How this calculator works

Post-money sets the ownership

Post-money is pre-money plus the investment. The investor owns their cheque divided by post-money, and any pre-money option pool comes out of the existing shareholders.

The formulas
Post-moneyPre-money + Investment
Investor ownershipInvestment ÷ Post-money
Founders keep100% − Investor − ESOP pool
Share pricePre-money ÷ Existing shares
Every field explained

What each input actually means

Basis
Whether the valuation you are entering is pre-money or post-money. The calculator derives the other one for you.
Pre or post-money valuation
The agreed value of your company, either before the investment goes in, or after, depending on the basis you picked.
Investment amount
The total cash the new investor is putting into this round. It sets both post-money and investor ownership.
New ESOP pool
The employee option pool you create as part of the round, as a percentage. Set up pre-money, it dilutes existing shareholders.
Existing shares
The number of shares outstanding before the round. Used to convert pre-money valuation into a per-share price.
Benchmarks

How much dilution is normal?

Typical dilution bands by round, so you know where your deal sits.

Pre-seed and seed: 10 to 20%

Founders typically give up a tenth to a fifth of the company per early round, often alongside a fresh option pool.

Series A: 15 to 25%

The classic A round dilution band. Much more than this early can leave little equity for later stages.

Later rounds: 10 to 20%

As valuations rise, the same cheque buys a smaller share, so percentage dilution usually eases over time.

Option pool: 10 to 15%

A typical pool to attract talent. Remember a pre-money pool comes out of your slice, not the investor’s.
