Pre-money and Post-money Valuation Calculator

Know exactly what an offer means. Enter either the pre-money or the post-money valuation and the investment amount to see investor ownership, what existing shareholders keep and, if you add an ESOP pool, the effective pre-money you are really getting.

QUICK ANSWERPost-money valuation = pre-money valuation + new investment. The investor’s ownership = investment ÷ post-money. Example: ₹40 Cr pre-money + ₹10 Cr investment = ₹50 Cr post-money, so the investor owns 20% and existing shareholders keep 80%.

Post-money = Pre-money + Investment
Investor % = Investment ÷ Post-money
Price per share = Pre-money ÷ Fully diluted shares before the round

Pre-money vs post-money: why the difference matters

When an investor says “₹10 Cr at ₹50 Cr”, always ask whether ₹50 Cr is pre or post. At ₹50 Cr pre-money they own 16.7%; at ₹50 Cr post-money they own 20%. The difference on a single round is several percentage points of the company.

Term sheets often require a new ESOP pool to be created “in the pre-money”. That means the pool is carved out before the investor comes in, so only existing shareholders are diluted by it. The effective pre-money (headline pre-money minus the pool’s value) is the number to compare between offers.

Worked example

₹40 Cr pre-money and ₹10 Cr investment with a 10% post-money ESOP pool in the pre-money: post-money ₹50 Cr, investor 20%, pool 10%, existing holders 70%. Effective pre-money is ₹35 Cr, not ₹40 Cr.

Frequently asked questions

How do I calculate post-money valuation?

Add the new investment to the pre-money valuation. ₹30 Cr pre-money plus ₹6 Cr raised gives ₹36 Cr post-money.

How do I calculate the investor’s percentage?

Divide the investment by the post-money valuation. ₹6 Cr ÷ ₹36 Cr = 16.67%.

Does a SAFE or convertible note change pre-money?

Yes. When SAFEs or notes convert in a priced round, their shares are usually counted in the pre-money, which dilutes founders further. Use the SAFE or convertible note calculator to see the full effect.
