Cap Table (Capitalization Table)

What Is a Cap Table?

A cap table, short for capitalization table, is the authoritative record of who owns a company. A cap table lists every share, option, warrant, and convertible instrument, who holds it, what was paid for it, and the ownership percentage each position represents on both an issued and a fully diluted basis.

How a Cap Table Works

A cap table starts simple and gets complicated in a predictable order. Founders hold common stock, an option pool is reserved, SAFEs or convertible notes are issued, and a priced round creates preferred stock with its own rights. Each subsequent round adds a class, and each sits above the previous one in a liquidation.

Two views of the same table tell different stories. The issued view counts only securities outstanding. The fully diluted view counts everything that could become a share: granted options, the unallocated pool, warrants, and the shares convertible instruments will produce. Investors negotiate on the fully diluted number, and founders who quote the issued number overstate what they own.

Every entry needs paper behind it: a board consent, a signed grant, an executed stock purchase agreement, and where relevant a timely 83(b) election. Diligence reconciles the cap table against those documents line by line, and missing paperwork delays closings or triggers a price re-trade.

How to Calculate Fully Diluted Ownership on a Cap Table

Formula: Ownership Percentage = (Shares Held / Fully Diluted Shares Outstanding) x 100

Worked example: a company has 8,000,000 common shares, 2,500,000 shares of Series A preferred, 900,000 granted options, 600,000 unallocated pool shares, 100,000 warrants, and SAFEs that will convert into roughly 400,000 shares. Fully diluted shares outstanding total 12,500,000.

A founder holding 4,000,000 shares owns 4,000,000 / 12,500,000 x 100, or 32 percent fully diluted. On issued shares alone the same founder appears to own 38 percent. That six point gap is the difference between a pitch deck slide and the number that governs a payout.

Cap Table in Plain English

A cap table is the scoreboard for ownership. Every time the company sells stock, grants an option, or takes convertible money, a row is added and everyone else's slice shrinks. The percentage matters less than what it is a slice of, which is why founders accept dilution: a smaller share of a much larger company is the trade.

Preferred Shares, SAFEs, and Convertible Notes on a Cap Table

Preferred stock is not common stock at a higher price. It carries a liquidation preference, usually 1x non participating: the holder takes their money back first or converts to common and takes their percentage, whichever is better. Participating preferred does both. Preferences also stack by seniority, so a later round is often paid ahead of an earlier one.

SAFEs and convertible notes surprise founders most, because they sit outside the share ledger until conversion. Instruments with different valuation caps convert at different prices in the same round, and post money SAFEs guarantee the investor a fixed percentage, pushing dilution from later instruments onto existing holders. Model the conversion before signing the next term sheet.

Option Pools and the Pre Money Pool Shuffle

Investors typically require an option pool of 10 to 20 percent of post round shares, large enough to hire the team the round is meant to fund. Where that pool is created decides who pays for it.

Consider a $20,000,000 post money round. A 15 percent pool represents $3,000,000 of value. Created pre money, as term sheets normally specify, that entire $3,000,000 comes out of existing holders before the new investor's shares are counted. Created post money, the new investor would share the cost. Negotiating the pool down, or basing it on a real hiring plan rather than a round number, is one of the highest leverage conversations in a financing.

Liquidation Waterfalls and 409A Valuations

A waterfall model runs the cap table through an exit and shows who receives what at each price, exposing what percentages hide. If a company has accumulated $40,000,000 of liquidation preferences and sells for $45,000,000, preferred holders take $40,000,000 and common splits $5,000,000, whatever the ownership column says.

A 409A valuation is a separate exercise: an independent appraisal of the fair market value of common stock, used to set option strike prices. It is refreshed at least annually and after any priced round; getting it wrong exposes option holders to tax penalties. The 409A value normally sits well below the preferred price investors pay, which is why employee options have value at grant.

Cap Table and the Closing Motion

A cap table is the permanent record of every time a company funded growth by selling ownership. Some is unavoidable, but much of it funds working capital gaps that better close mechanics would have prevented. When Propose, Close, Collect, and Renew are fragmented, contracted revenue arrives months after commitment and the shortfall gets covered with equity. Ratio, the Closing Motion Platform for B2B tech, addresses that gap at its source. Ratio Trade pays the seller the full total contract value upfront while the buyer pays monthly or quarterly, and Ratio Boost converts an existing base of recurring contracts into upfront growth capital with no dilution and no warrants. Neither adds a row to the cap table.

Common Questions About Cap Tables

What is the difference between issued and fully diluted shares?

Issued shares are securities outstanding today. Fully diluted shares add granted options, the unallocated pool, warrants, and shares issuable on convertible notes and SAFEs. Fully diluted is the basis investors use, and it always shows the lower ownership percentage.

Does a SAFE appear on the cap table before it converts?

Not as issued shares, but it must be tracked and modeled. Well run companies keep a pro forma view showing what each SAFE and note converts into at the expected next round price. Discovering that mid negotiation is how founders end up with far less than they thought.

How often should a cap table be updated?

At every event that changes ownership: each grant, exercise, transfer, conversion, or financing. Companies past a few dozen holders usually move off spreadsheets onto dedicated software, because a stale cap table creates legal exposure and slows every future transaction.

Key Takeaways

• A cap table records every share, option, warrant, and convertible instrument, and who holds each.
• Fully diluted ownership divides shares held by all shares that could exist, and it is what investors negotiate on.
• Preferred stock carries liquidation preferences that can leave common holders with little at modest exits.
• Option pools created pre money are paid for entirely by existing holders, so pool sizing is a real negotiation.
• Keeping the cap table clean is a diligence requirement, and non dilutive funding keeps rows off it entirely.
