What is a cap table?
A cap table, short for capitalization table, is a document that details your company's equity ownership structure. It records every shareholder, the number of shares they own, the types of equity they hold, and any convertible instruments—SAFEs or convertible notes—that may convert into equity later. For startups, the cap table is the single source of truth for your company's ownership, tracking ownership from the day you incorporate through every funding round, new hire, and change in ownership.
Maintaining an accurate cap table is especially important for startups and high-growth companies where ownership percentages can change dramatically following funding rounds, employee option pool creation, and secondary transactions. Cap tables also play a major role in due diligence for potential investors.
This video gives an introduction to cap tables as part of Carta’s free Cap Table 101 curriculum.
Why do startups need a cap table?
A cap table is more than a record of who owns shares. It's a tool you'll rely on at nearly every major milestone.
Fundraising readiness
Investors expect a clean cap table before they write a check. During due diligence, venture capitalists (VC) review your ownership structure to assess founder commitment, existing investor rights, and potential red flags. If your ownership structure is unclear, investors will question your ability to manage the company itself. A well-maintained cap table signals operational maturity and makes the fundraising process faster. A messy or incomplete cap table slows deals down and can kill them outright.
When the market tightens, investors often use their leverage to negotiate for complex terms that can complicate your ownership structure. For example, as the market cooled, the use of investor-friendly deal terms spiked. The share of rounds with participating preferred stock climbed from 4.8% in Q4 2021 to more than 15% in early 2023—then fell by more than half by Q4 2024 as market conditions shifted back in founders' favor.
The market has since shifted back in founders' favor. According to Carta's State of Private Markets Q1 2026 report, the down-round rate fell to 11.4% in Q1 2026, returning to 2019–2020 levels. Deal terms now broadly favor founders, which means you may have more negotiating room on provisions like liquidation preferences and anti-dilution provisions, depending on your stage and traction.
Dilution tracking
Every time you issue new shares, whether to investors, employees, or advisors, your existing ownership percentages drop. Dilution is unavoidable as you grow—but manageable if you track it. What matters is understanding exactly how much dilution each round creates and whether the tradeoffs are worth it.
Your cap table lets you model scenarios before they happen. You can see what a $5 million Series A at a $20 million pre-money valuation does to your ownership, or how a 15% option pool expansion affects existing shareholders. Without this visibility, you are negotiating blind.
Hiring and talent retention
Equity is one of the most powerful tools startups have for attracting talent, especially when you cannot compete on cash salary alone. Your cap table tracks the employee equity pool, individual option grants, vesting schedules, and exercise prices.
When a candidate asks, “What percentage of the company does my grant represent?” you need an accurate answer. When your board asks, “How much of the option pool remains unallocated?” you need that answer, too. A cap table keeps both numbers current and defensible.
Beyond recruiting, your cap table supports retention decisions. You can identify employees whose grants are approaching full vesting (and who may need a refresh grant to stay motivated), track the cost of exercises for early employees considering whether to buy their shares, and model the impact of a new option pool expansion on existing holders.
The structure of a cap table
The complexity of your cap table depends on your company’s size and stage. A pre-seed startup with two founders may have a cap table that fits on a single page. A Series C company with multiple investor classes, an option pool, and convertible instruments will have something considerably more involved.
Regardless of your stage, every cap table tracks the same core information: who owns equity, what type of equity they hold, and how much of it they have. The structure should make it possible for any reader, whether an investor, a lawyer conducting diligence, or a new CFO joining the company, to understand the full ownership picture without needing additional context.
Key components
A cap table is organized into categories that cover ownership, transaction history, and other financial information.
Ownership details
This section covers who holds equity, in what form—shares, options, warrants, convertibles—and what percentage of the company that stake represents.
Shareholder information: Names, entities, and roles like founders, investors, employees, and advisors.
Number of shares: Total shares owned by each shareholder.
Ownership percentage: The percentage of the company each shareholder owns.
Types of equity
Not all equity is the same, and your cap table distinguishes between the different types you issue and the terms of each. As a founder, you'll encounter several common forms of equity.
Common stock: The basic ownership shares in a company. Founders and early employees typically hold common stock.
Preferred stock: Typically issued to investors in funding rounds, preferred stock usually carries special rights like priority repayment in a sale and additional voting rights.
Stock options: The right to buy a set number of shares at a fixed price.
Restricted stock: Shares granted to employees or service providers that are subject to vesting and other restrictions.
Warrants: Similar to stock options but are often granted to investors, lenders, or partners as an incentive.
Convertible instruments: Investments that convert into equity at a later date. The most common types are SAFEs (Simple Agreements for Future Equity) and convertible notes.
Share classes
Different types of equity are organized into share classes, and each class can have different rights. The most important distinction for a startup founder is between common and preferred shares.
Preferred shares, held by investors, often include a liquidation preference. This means investors get their money back before common stockholders in the event of a sale. Share classes can also have different voting rights, which affects control over company decisions and overall board management.
Transaction history
Your transaction history is the official record of every equity event that changes who owns what on your cap table.
Maintaining a detailed transaction history is important for valuations audits and due diligence. Examples of transactions you'll need to record include:
Funding rounds where new shares are issued to investors.
Stock grants issued to new hires or advisors.
Employees exercising their stock options to purchase shares.
Valuations
Valuations give your company's shares a monetary value. The cap table tracks these values as they change over time. Here are the types of valuations you might include:
Pre-money valuation: The value of the company before a new funding round.
Post-money valuation: The value of the company after the funding round.
409A valuation: An independent appraisal of a private company's fair market value (FMV). The 409A value sets the strike price for employee stock options.
Price-per-share: The value of each preferred share sold in the funding round, calculated using the valuation divided by the total number of fully-diluted shares. Note that the valuation of the latest preferred share class does not necessarily imply that common shares have the same FMV.
Dilution analysis
When you issue new shares to investors or employees, the ownership percentage of existing shareholders decreases. A well-maintained cap table allows you to use scenario modeling to understand how new funding or hiring will affect everyone’s ownership.
Dilution is a normal and necessary part of growing a startup through fundraising and hiring. The key is to manage it strategically.
Exit scenarios
One of the most powerful uses of a cap table is modeling exit scenarios. This involves running a waterfall analysis, which projects how the money from a future sale, initial public offering (IPO), or other liquidity event would be distributed among all shareholders.
This analysis is based on the specific rights of each share class, especially the liquidation preferences of your preferred stock. It shows who gets paid, in what order, and how much they receive, providing clarity on liquidity for founders, employees, and investors alike.
Common formats
Choosing the right format for a cap table depends on your company's needs. At the earliest stages, many founders use simple spreadsheets in Excel or Google Sheets to track ownership. A basic spreadsheet cap table typically has shareholders listed in rows and ownership details in columns, with separate tabs for each share class or equity instrument. This format is adequate when you have two or three founders and no outside capital.
As your company grows, spreadsheets become unreliable. Formulas break, version control becomes impossible, and the risk of errors increases with every transaction. Most companies transition to dedicated cap table software after their first or second funding round, when the complexity of tracking multiple share classes, vesting schedules, and convertible instruments exceeds what a spreadsheet can safely handle.
Cap table example
While there's no standard format, here's an example of what a cap table could look like:
In practice, your cap table will also show the price per share, the date of each issuance, any vesting conditions, and the rights attached to each share class. A fully diluted cap table would additionally include shares from the conversion of all outstanding SAFEs, convertible notes, options, and warrants.
Fully diluted shares and the fully diluted cap table
As you add options, warrants, SAFEs, and convertible notes, your cap table starts to show two different pictures of ownership. Fully diluted shares are the total number of shares that would exist if every option, warrant, SAFE, and convertible note were exercised or converted into stock. A fully diluted cap table, sometimes called your fully diluted capitalization, shows ownership on that basis, rather than counting only the shares issued and outstanding today.
The distinction matters because it changes the ownership percentages people actually hold. Consider three related terms:
Authorized shares: The maximum number of shares your company is allowed to issue, set in your incorporation documents.
Issued and outstanding shares: The shares that have actually been granted and are held by shareholders today.
Fully diluted shares: Outstanding shares plus everything that could convert into shares later, such as your unexercised option pool and outstanding convertibles.
Investors negotiate on the fully diluted number, not the outstanding one. When a term sheet quotes a price per share or a target ownership percentage, it almost always assumes full dilution, including the new option pool you agree to create. That is why founders are sometimes surprised by their ownership after a round: the outstanding cap table looked healthier than the fully diluted one. Modeling ownership on a fully diluted basis, ideally with scenario modeling, lets you see the real effect of share dilution before you sign anything.
How to create a cap table
The first cap table you build will be the simplest one you ever have. You're capturing a small set of facts: who owns equity, what type, and on what terms. What matters is getting those facts down accurately, in a format that can grow with you. Work through the steps below in order, adding each layer as it applies to your company.
The initial setup
Gather all the current equity and ownership information and legal documents to create a complete and up-to-date picture of your company's ownership structure. Any missing or inaccurate information can lead to complications during fundraising or audits.
You will need:
Total authorized shares: The maximum amount of shares the company can issue.
Issued and outstanding equity (stock, shares, convertibles): The number of shares currently allocated to stakeholders.
Shareholder details: Names, roles, and contributions of all equity holders.
Equity types: Details of issued securities including common and preferred stock, stock options, warrants, and convertible notes.
Funding rounds: Details of previous financing rounds, including valuations, total amount raised, and share price.
Option pool allocation: This includes the number of shares reserved for employee equity plans, issued and outstanding shares, exercised stock options, and more.
Relevant documentation: Any documents including incorporation documents will streamline this process.
Add founders’ equity
Next, you'll record the initial equity split between you and your co-founders. To add founders' equity, record the number of common shares assigned to each founder based on agreed ownership split, and include a column for any applicable vesting schedules.
How you split equity has long-term consequences, and the norms are shifting. Equal splits are now the most common approach, though the right structure for your team depends on each founder's contributions, capital invested, and role going forward.
If you receive restricted stock, file a timely 83(b) election with the IRS, and as part of your tax planning for small businesses, explore strategies like qualified small business stock (QSBS) to potentially save on future taxes.
Add investor equity
If you've raised money from an angel investor or through a pre-seed round, add their investment to the cap table. This section will record the total investment amount, the total number of shares purchased by investors (or convertible notes or SAFEs), the price-per-share, the share class of the equity, and the voting rights and liquidation preferences agreed to with their equity.
For SAFEs and convertible notes, the instruments will not convert into equity until a qualifying financing event. Your cap table should still track them as outstanding obligations, showing the investment amount, the valuation cap, and the discount rate. This gives you and your investors a clear picture of the fully diluted ownership structure.
Pro-forma (post-financing) cap table
Before you close a round, you'll want to see what your ownership looks like the day after it closes. A pro-forma cap table, also called a post-financing cap table, is a modeled version of your ownership that reflects a proposed round: the new money in, the new shares or converted SAFEs, any option pool top-up, and the resulting ownership percentages for everyone.
This is the view founders and investors actually negotiate against. During a raise, you'll typically compare your current cap table with one or more pro-forma versions to answer a simple question: If we accept these terms, who owns what afterward? Building it on a fully diluted basis, and using scenario modeling to test different valuations and pool sizes, turns a term sheet into numbers you can react to. Depending on your situation, a small change in the pre-money valuation or option pool can move your ownership by several points, so it pays to model the round before you sign it.
Add an option pool
An employee stock option pool is a portion of your company's shares that you reserve for future employees as equity.
Be strategic about the size of your option pool, as it's a resource that changes as your company grows. While every situation is different, benchmark data can provide a concrete starting point. Carta data shows that the median startup has set aside 15% of its fully diluted equity for its employee option pool at the time it raises a Series A. This number inches up gradually from one fundraising stage to the next, reaching 16.4% by Series C and 19.6% by Series E+.
Cap table management best practices
As your company grows, your cap table becomes a strategic tool. Regular cap table management helps you avoid costly errors, remain in compliance with regulations, and build trust with your stakeholders.
Maintain accurate records
Your cap table must be the single record of ownership. Managing ownership across multiple spreadsheets, email threads, and legal documents is how errors find their way into your cap table—and into due diligence conversations.
"Everything is on one platform, which is really nice. I don't have to worry about information being manipulated or misinterpreted, because data integrity is built into how the system operates."
—Amanda Purfurst, Senior Controller, Automox
To stay ahead of mistakes:
Regularly verify share ownership, equity types, and transaction history.
Reconcile cap table data with term sheets, stock certificates, and board resolutions.
Include all equity and convertible debt instruments in your cap table.
Use consistent layouts and labels on columns and rows, and differentiate clearly between share classes and their associated rights.
Update your cap table regularly
Your cap table must be updated in real time with every new stock grant, transfer, or funding round to keep you investor-ready.
Record new issuances, grants, and transfers immediately after they occur.
Show changes in ownership percentage and share dilution after a funding round.
Review and update quarterly.
Plan for dilution
Don't let fundraising rounds catch you off guard. Use scenario modeling to understand exactly how new investments will impact ownership across the table.
Dilution adds up fast across rounds. Carta's Founder Ownership Report 2026 shows that after a seed round the median founding team collectively owns 56.2% of its equity, and that figure falls to 36.1% at Series A and 23% at Series B. Seeing the curve early makes it easier to plan.
Model dilution scenarios when preparing to issue new shares during fundraising.
Communicate the impact of dilution to stakeholders.
Size your option pool appropriately to avoid frequent dilutive increases in the future.
Ensure compliance
Equity is governed by a complex set of tax and legal regulations. Using a platform with built-in compliance for things like 409A valuations and financial reporting helps you avoid penalties and stay audit-ready. That audit-readiness becomes real as you scale, as ButterflyMX found working through a Big Four audit:
"As you become a bigger and more complex company, equity work is a consequential part of a Big Four audit. The audit required extensive cap table details and comprehensive equity analysis."
—Bary Dunn, CFO and Head of Strategy, ButterflyMX
What this looks like in practice:
Use cap table software with built-in compliance support.
Maintain documentation of board approvals and 409A valuations.
Understand the regulatory landscape and comply with reporting requirements.
Common cap table mistakes to avoid
Experienced founders make cap table errors. The consequences range from a painful due diligence conversation to a failed round. Here are the most common mistakes to watch for.
Relying on spreadsheets too long: Spreadsheets work fine when you have two founders and no outside capital. But once you add investors, convertible notes, or an option pool, manual tracking becomes error-prone. A single misplaced formula can misstate ownership percentages across your entire table.
Not updating after every transaction: Every stock grant, option exercise, note conversion, or share transfer needs to be recorded immediately. Batching updates (or forgetting them entirely) creates discrepancies that surface at the worst possible time, usually during due diligence.
Ignoring convertible instruments: SAFEs and convertible notes don't appear as equity on your cap table until they convert, but they will affect ownership when they do. Failing to model their impact gives you an incomplete picture of dilution.
Not planning for dilution: Founders who don't model future rounds often underestimate how much ownership they'll give up. Running scenario models before each fundraise helps you negotiate from a position of clarity rather than surprise.
Choosing the wrong management tool: Not every cap table platform handles every stage well. Some tools are built for pre-seed simplicity; others support the complexity of multi-round, multi-class structures. Picking software that won't grow with you means a painful migration later, in most cases right when you can least afford the distraction.
Getting ahead of these is easier when your cap table is clean from the start, a lesson George Avetisov took into his second company:
"When we founded 1up, I bought Carta immediately, pre-funding, pre-customer, pre-revenue, because the cap table was such a mess at my first startup. I wasn't going to make the same mistake. This time, our cap table and all of our investor docs have been clean since day one."
George Avetisov, founder and CEO of 1up
Tools for cap table management
As a founder, you have two main choices for managing your cap table: a simple spreadsheet or dedicated cap table software. Modern, professional software is designed to handle the complexities of equity management, saving you time and preventing expensive mistakes. Here's what each option looks like in practice.
Cap table template
In the very early stages of a startup, cap tables often live in a spreadsheet because ownership is usually relatively simple and easy to track early on. But if you're creating a cap table for the first time, starting from scratch can get complicated quickly.
Download Carta's free cap table template for a useful starting point, but remember that Excel and Google Sheets won't scale with you as you grow.
Why spreadsheets don't scale
Relying on a spreadsheet to manage your cap table is a common mistake for early-stage founders. As you hire employees, raise funds, and issue more equity, the risk of a small formula error or an outdated version causing a major problem increases.
While some companies begin by tracking their ownership in a spreadsheet, the path for growing VC-backed startups is clear. More than 65,000 companies now use dedicated platforms to manage over $4.5 trillion in equity, establishing a clear best practice for scalable and accurate cap table management.
Spreadsheets | Cap table software |
Manual updates required | Automatically updates with each transaction |
High risk of human error | Reduces errors with built-in checks |
Difficult to share and track versions | Centralized, single source of truth |
Lacks built-in compliance | Includes compliance and reporting tools |
Does not scale with company growth | Scales from incorporation to IPO |
Carta began over a decade ago with the simple solution of fixing cap tables and taking them off manual spreadsheets. If your cap table still lives in a spreadsheet, you have to be diligent about using consistent names, updating your version whenever something happens, and sending the updated version to relevant stakeholders, like your lawyer.
Cap table software
Cap table software is the modern standard for serious founders who want to manage their equity professionally. It automates workflows, provides a secure portal for all stakeholders, and saves you time and legal fees. Request a demo to see how it works.
Carta is the equity management platform trusted by over 65,000 companies, from new startups to mature companies.

Keeping your ownership clear as you grow
Your cap table is the foundation of everything that follows: fundraising, hiring, dilution, and eventually an exit. Build it accurately from day one, keep it current after every event, and model rounds on a fully diluted basis before you sign, and it becomes a strategic tool rather than a source of surprises. Founders who start on dedicated software avoid the version-control mess that so often shows up during due diligence.

Frequently asked questions about cap tables
Why is it called a cap table?
"Cap" is short for capitalization, which refers to how a company is funded through its equity and other securities. A cap table is simply the table that lays out that capitalization: who holds it, how much, and in what form. You'll also see it written as "captable" or "cap. table," but "cap table" is the standard spelling.
How do I create a cap table?
Start by listing all shareholders in your company, including founders, investors, and employees. For each, record the number of shares they own, the type of shares, and any other issuances like option grants or convertible notes. Next, calculate the total outstanding shares and determine each person's ownership percentage. Organize this information into a table, updating it whenever new equity is issued, options are exercised, or ownership changes.
Can an LLC have a cap table?
Yes. LLCs issue "membership units" instead of shares, but a cap table is still needed to track ownership percentages and capital accounts. Carta for LLCs is specifically designed to handle the unique equity structures of limited liability companies.
Do all companies have a cap table?
Any company with more than one owner, or that plans to issue equity to investors or employees, needs a cap table. It's the only way to maintain a clear and accurate record of who owns what.
Is a cap table a public document?
No. For private companies, the cap table is a highly confidential document, typically shared only with key stakeholders like board members, investors, and lawyers during specific events like fundraising or legal reviews.
How do I prepare my cap table for due diligence or audits?
Verify all equity issuances, transfers, option grants, and conversions against your supporting legal documents so the record is accurate and current. Make sure ownership percentages, vesting schedules, and any outstanding convertible securities are clearly documented and current.
How do stock options and vesting show up on a cap table?
Options affect your fully diluted share count before they affect anyone's issued shares. Establishing an option pool increases the fully diluted count, which reduces existing shareholders' ownership once options are exercised, even though outstanding share counts don't change until exercise. For each grant, a cap table typically tracks the total shares granted, the vesting schedule, and the number of shares vested to date, often in separate columns, so you can see what's earned versus still unvested.
How do I handle multiple share classes in a cap table?
List each share class separately, recording the number of shares, holders, and specific rights for each. Then calculate ownership percentages and fully diluted shares for each class and in total.
How do I use cap table analytics to inform my growth strategy?
Cap table analytics reveals ownership distribution, potential dilution from future fundraising or option grants, and identifies capacity for new equity incentives. This enables more informed decisions during investor negotiations, employee compensation, and planning for future capital needs.
Can I add historical stock purchase plans and equity grants in a cap table?
Yes. You should include historical stock purchase plans, shareholder agreements, and equity grants in your cap table to maintain an accurate record of all ownership changes and provide a complete view of your company's equity history.
What is the best way to share cap table data with investors securely?
Use reputable cap table management software with controlled access, or share encrypted files via secure platforms, so only authorized recipients can view or download sensitive information.
How do funding milestones reflect on a cap table?
Funding milestones appear as new share issuances or classes to new investors, updating ownership percentages and valuations to show the impact of each financing round on all shareholders.
How does cap table software help with fundraising, forecasting, and growth decisions?
Cap table software with scenario modeling ties all of these together. It displays current ownership, models dilution from new investments, and forecasts exit values by calculating payouts to each shareholder class based on ownership, preferences, and dilution.
How do I choose the right cap table software for my startup?
Match the software to how your equity will grow. Look for accurate equity tracking, support for multiple share classes, vesting and option management, scenario modeling, compliance tools, secure document storage, permission controls, and investor reporting, plus the integrations, data security, scalability, and customer support your team will lean on as you scale.
