- A cap table is the record of who owns what, on both an issued and a fully diluted basis. Its value comes entirely from being correct and current.
- It tracks four things: founders, investors, the ESOP pool, and convertible instruments that will become shares.
- Fully diluted is the number that matters. It assumes every option and convertible has already turned into shares.
- Clean means reconciled. Update on every trigger (grant, exercise, transfer, round, lapse) and keep the table matched to your statutory registers and resolutions.
- A spreadsheet has a shelf life. Once ownership has moving parts, move to software that calculates and versions for you.

What a Cap Table Is, and What It Tracks
A capitalisation table, or cap table, is the record of who owns your company and in what form. It is not an accounting statement and it is not the same as your shareholder register at the registrar, though it must agree with both. Think of it as the master ownership ledger: for every holder it records how many shares or options they hold, of which class, on what date, and what percentage of the company that represents. Managing it well is a founder responsibility that never goes away, because the cap table is what everyone else trusts to know their stake.
The reason it needs management is that a cap table has four distinct kinds of rows, and each behaves differently over time. Founders hold plain Equity Shares. Investors hold shares, often of a different class. The ESOP pool is a reserved block that is granted out over years. Convertibles are promises that turn into shares later. Here is the anatomy.
| Row type | What it holds | What moves it |
| Founders | Equity Shares from incorporation | Transfers, buybacks, new rounds diluting them |
| Investors | Equity or preference shares, by class and round | New rounds, secondary sales, conversions |
| ESOP pool | Reserved options plus each employee grant | New grants, vesting, exercises, lapses, top-ups |
| Convertibles | Notes, CCPS, CCDs, warrants awaiting conversion | Conversion at the next round on their terms |
Notice that the ESOP pool is not a separate document that lives beside the cap table. It sits on the cap table as one of these row types, reserved up front and then filled in grant by grant. That is why pool design and cap-table management are really the same discipline seen from two angles. For how to size and structure that pool in the first place, read our guide on the ESOP pool. For the wider view of running your ownership record and equity program the company-side way, see our pillar guide on administering ESOPs and equity.
Issued vs Fully Diluted Shares
The single concept every founder must be fluent in to manage a cap table is the difference between issued and fully diluted shares. Get this wrong and every percentage you quote is wrong. Issued shares are the shares actually allotted and sitting on the register today. Fully diluted shares assume everything that can become a share already has: the entire ESOP pool, all options, all warrants, and every convertible converted at its terms.
- Founders’ Equity Shares
- Investor shares already allotted
- Options already exercised into shares
- Excludes the ungranted pool
- Excludes unconverted instruments
- Everything in the issued column, plus
- The whole ESOP pool, granted and ungranted
- All outstanding, unexercised options
- All warrants
- All convertibles, converted at their terms
The whole ESOP pool counts against fully diluted ownership even before a single option is granted. This is why creating or topping up the pool dilutes existing holders on day one, and why the pool always belongs on the cap table, not in a side file.
Because both views are legitimate for different purposes, a well-managed cap table shows each holder’s percentage on both bases at once. When someone asks for your ownership breakdown, the professional answer states which basis you are on. Confusing the two is one of the most common cap-table errors, and we cover the rest in our companion piece on the cap-table mistakes founders make.
How to Build and Maintain One
Building a first cap table is not hard; keeping it correct is the work. Start simple and add structure only as events demand it. The sequence below is the one that keeps a table trustworthy from incorporation onward.
The ESOP portion of this work is the part that moves most, because grants vest monthly, get exercised, and lapse on exit. Doing it by hand is where cap tables drift. A dedicated tool that runs the vesting engine and feeds exercises and lapses straight into your option-pool view removes most of that drift, which is exactly what ESOP Flow is built to do for the equity side of your cap table.
Keeping It Clean and Reconciled
A cap table is only worth anything if it is correct, and correct means reconciled: the cap table, your statutory registers, and the resolutions that authorised each change all tell the same story. Most cap-table pain is not from a single big error but from many small unreconciled ones that compound until nobody trusts the file. Here is the hygiene checklist that prevents it.
The most expensive cap-table failure is the reconciliation gap: the cap table says one thing, the ESOP register says another, and the board resolution a third. It stays invisible until a buyer’s or investor’s lawyer finds it, at which point it can hold up a deal or shave the valuation. Reconcile continuously, not the week before a raise.
Triggers to Update, and When the Spreadsheet Stops Working
You do not update a cap table on a schedule; you update it on events. If you can name the triggers, you will never let the table drift. Every one of these is a moment the cap table changes and must be edited the same day.
A spreadsheet can hold all of this at the very start, when it is just founders and a clean split. It stops working the moment these triggers start firing often, and especially once ESOPs vest, because now the numbers change every month and formulas get copied wrong, versions diverge, and there is no audit trail. That is the point to move to software: not for the features, but for one live, calculated, versioned source of truth. We go deeper on the exact signals and the tool options in our guide to cap-table mistakes and how to avoid them.
“The cap table is not a document you build for a fundraise. It is a ledger you keep every week, so that when the fundraise comes, there is nothing to build. Founders who treat it as hygiene never have the pre-diligence panic.”
Ankit Sarawagi, Founder, CFOmatrixFrequently Asked Questions
What is a cap table?
A cap table, or capitalisation table, is the record of who owns your company and in what form. It lists founders and their Equity Shares, each investor’s holding, the ESOP pool and every option grant, and any convertible instruments waiting to become shares. Its job is to answer, at any moment, who owns what percentage on both an issued and a fully diluted basis. Kept properly, it is the single source of truth that founders, the board, investors and auditors all rely on.
What does a cap table track?
A cap table tracks every claim on your company’s equity: founders’ Equity Shares, each investor’s shares and share class, the ESOP or option pool (both the reserved size and individual grants through vesting, exercise and lapse), and convertible instruments such as convertible notes, CCPS, CCDs or warrants that will turn into shares later. For each holder it records the number of shares or options, the class, the issue or grant date, and the resulting ownership percentage on an issued and a fully diluted basis.
What are fully diluted shares?
Issued shares are the shares actually allotted and sitting on the register today. Fully diluted shares assume every instrument that can become a share has already become one: the entire ESOP pool (granted and still ungranted), all outstanding options, warrants, and every convertible instrument converted at its terms. Fully diluted ownership is almost always the number that matters, because it shows each holder’s true stake once all commitments crystallise. Investors, term sheets and pool-sizing are all discussed on a fully diluted basis.
How do I keep my cap table clean?
Keep one master version that everyone treats as authoritative, and update it on every trigger rather than in a rush before a raise. The triggers are: a new option grant, an exercise, a share transfer or buyback, a new round or convertible, a pool top-up, and a lapse or forfeiture on exit. After each change, reconcile the cap table to your statutory registers and board and shareholder resolutions so the two always agree. Store the supporting document with every entry, and once your ownership picture has moving parts, move off a shared spreadsheet onto software that calculates and versions for you.
When should I stop using a spreadsheet for my cap table?
A spreadsheet is fine while it is just founders with a simple split. It stops working once ownership starts moving: your first external round or convertibles, and especially your first ESOP grants, because vesting, exercises and lapses change the numbers every month. The warning signs are multiple versions floating between founder, CFO and lawyer, no audit trail, manual dilution math you no longer trust, and a scramble to rebuild the table before diligence. At that point move to dedicated software so there is one live, calculated, versioned source of truth.
How does the ESOP pool show up on the cap table?
The ESOP pool sits on the cap table as a reserved block of fully diluted equity, typically five to fifteen percent for startups. On a fully diluted basis the whole pool counts against ownership, whether or not it has been granted yet, which is why creating or topping up the pool dilutes existing holders. Within that block the cap table tracks each grant through vesting, exercise and lapse: exercised options become issued shares, and lapsed or forfeited options return to the pool. Keeping the pool and the grant ledger reconciled to the cap table is core cap-table hygiene.
