Reading Your Cap Table: How to Project Employee Dilution Across Rounds

You joined a Series B startup three years ago with 0.4% of the company. The company just closed a Series D at a $2.1 billion post-money valuation. You do the math and expect $8.4 million on paper. Your grant documents say you still own 35,000 shares. The actual number on your equity portal reads 0.19%. The difference is dilution, and it compounds silently across every financing, option pool refresh, and convertible note conversion.

Reading a cap table is the only way to project where your ownership actually lands at exit. Most employees never see the full document. What you can see, in your offer letter and equity portal, is enough to model the likely range if you know what to pull out and what assumptions to apply.

This guide walks through the line items that matter, how to model dilution from a typical late-stage path, and how to convert shares to dollars under common exit scenarios.

What a cap table actually contains

A cap table lists every share-issuing event and every security convertible into shares: founder common, employee option pool, preferred shares by series, warrants, SAFEs, convertible notes, and phantom equity if any. The columns usually show shares outstanding, shares on a fully-diluted basis, price per share, liquidation preference, and ownership percentage.

Fully-diluted count includes all issued shares plus every unexercised option, unvested RSU, warrant, and convertible instrument. This is the number you care about when projecting your stake. Issued and outstanding excludes options not yet exercised and is almost always smaller.

Three numbers matter most to an employee projecting outcomes:

• Total fully-diluted shares outstanding.
• Unissued option pool reserved for future grants (the “available pool”).
• Liquidation preference stack by series.

Your offer letter gave you a share count. Your percentage at grant equals your shares divided by fully-diluted shares on the grant date. Every subsequent financing and pool refresh changes the denominator.

How dilution compounds across rounds

A typical pre-IPO path from Series B to IPO involves three to five more priced rounds plus one or two pool refreshes. Each event dilutes existing holders unless they participate in the round pro rata, which employees almost never do.

A standard Series C might issue new preferred stock equal to 15 to 20% of post-money. The board also commonly refreshes the option pool back up to 10 to 15% at each round. If you held 0.4% before a Series C that issued 18% new shares and refreshed the pool by 5%, your post-round ownership falls to approximately 0.4% × (1 - 0.18 - 0.05) = 0.308%.

Two more rounds with similar dilution profiles take you to around 0.19%, which matches the scenario above. That is not a calculation error. That is how late-stage financing works.

Anti-dilution and what it does not protect

Employees holding common stock have no anti-dilution protection. Preferred investors often have weighted-average anti-dilution for down rounds, which adjusts their conversion ratio. When you read about anti-dilution in financing documents, it applies to the preferred stack, not to you.

Option pool refreshes before new rounds

A detail worth flagging: most term sheets require the option pool refresh to happen before the new money comes in. This means existing shareholders, including employees, absorb the full dilution of the pool refresh. Incoming investors get diluted only by their own round.

If you see a board deck showing “pre-money option pool shuffle,” that phrase describes the mechanic that shifts dilution from new investors onto existing holders.

Modeling your likely exit outcome

Start with the current fully-diluted share count and your current share count. Then project dilution from remaining rounds.

A framework that gets you within 20% of reality most of the time:

If you are at Series B now and expect the company to IPO in three years after two more priced rounds plus a pool refresh plus IPO issuance, total dilution from here is roughly 0.77 × 0.85 × 0.95 × 0.90 = about 56% of your current stake preserved. Your 0.4% becomes approximately 0.22% at IPO.

Converting percentage to dollars

Exit value × your percentage = gross proceeds on common. Subtract liquidation preference to common holders and you land on what you actually receive.

At a $5 billion IPO market cap with 0.22%, gross proceeds are $11 million. If the preference stack is 1x non-participating on $800 million raised, preferred either converts to common (because their common share is worth more than $800 million) or takes preference. Above roughly $1.2 billion valuation in most late-stage deals, preferred converts and common holders are not clawed back.

Reading liquidation preference

Liquidation preference sets the floor for preferred shareholders in a sale or IPO. The two variables that matter:

• Multiple: usually 1x, sometimes 1.5x or 2x in down rounds or distressed financings.
• Participation: non-participating (preferred takes preference or converts, not both), participating (preferred takes preference and then shares in the residual), or capped participation (participates up to a cap, usually 2-3x).

At IPO, preferred typically converts to common automatically, so the stack mostly matters in an acquisition scenario below the stack’s break-even conversion point.

The break-even math for acquisitions

If total preference is $600 million, total fully-diluted shares are 200 million, and preferred represents 120 million of those shares, the preferred break-even is the acquisition price at which preferred’s common share (120/200 = 60% of proceeds) equals the $600 million preference. That equation resolves to a $1 billion acquisition price. Below $1 billion, common holders get diluted by the preference stack. Above it, preferred converts and common holders take their pro-rata share.

Questions to ask your equity team

Most companies will answer these if you ask directly through IR, finance, or your equity portal support:

• What is the current fully-diluted share count?
• What is the current unissued option pool?
• What is the 409A price per share as of the most recent valuation?
• What is the aggregate liquidation preference across the preferred stack?
• Are there any outstanding SAFEs or convertible notes, and what is the aggregate face value?

You will not get a copy of the full cap table. You will usually get these aggregate numbers if you frame the request as “for personal financial planning.”

Frequently asked

Does exercising my options change my percentage?

No. Your percentage on a fully-diluted basis is the same whether your options are exercised or not. Exercising converts options to shares and changes the issued-and-outstanding count, but not the fully-diluted count.

How do SAFEs affect my dilution?

SAFEs convert at the next priced round, usually at a discount or cap. Face value divided by conversion price equals shares issued. If the company has $50 million in SAFEs that convert at a $1 billion cap, that is 5% new shares at the next priced round, on top of any new money in the round itself.

What about secondary sales by founders?

Founder secondary sales do not dilute you. They transfer shares from one holder to another. What can dilute you is a tender offer paired with a primary issuance to the acquiring investor, but pure secondary is share-count-neutral.

How do I know the fully-diluted share count?

Your equity portal often shows it under “company summary” or “plan summary.” If not, ask finance or investor relations. Public filings for late-stage companies sometimes disclose it in press releases or S-1 drafts shared during pre-IPO windows.

Will my options get repriced if there is a down round?

Usually not for employees. Repricing employee options requires shareholder approval and accounting consequences under ASC 718. Boards sometimes do it for retention during extended down markets, but it is not automatic.

Next step

Pull the three numbers from your equity portal today: your fully-diluted share count, total fully-diluted shares outstanding, and the latest 409A price per share. Multiply your shares by 409A to get your current paper value. Then run the dilution framework above for the rounds you expect before a liquidity event. That gives you a first-pass projection you can refine as the company raises.
