Calculate your startup's post-money valuation after a funding round using investment amount and equity percentage.
Pre-money Valuation ($)
Investment Amount ($)
Use this calculator to estimate post-money valuation and ownership after a funding round.
Add the agreed company valuation before the new investment. Use the same valuation basis shown in the term sheet or investor discussion.
Add the amount of new capital being invested in the round. Keep the currency consistent with the pre-money valuation input.
Run the calculator to see post-money valuation, investor equity, and remaining founder ownership based on the basic round math.
Test different investment amounts and pre-money valuations to see how dilution changes before negotiating or accepting a funding offer.
Understand valuation and dilution before negotiating a startup financing round.
01
See how much ownership shifts to new investors after the round so founders can understand the tradeoff between capital raised and equity retained.
02
Use clear pre-money and post-money numbers when discussing term sheets, ownership, and round structure with angels, seed funds, or venture investors.
03
Model different valuation and check-size combinations to see which offer creates the best balance of capital, dilution, and post-round ownership.
04
Keep pre-money, investment amount, post-money valuation, investor equity, and founder ownership in one calculation to reduce negotiation mistakes.
A post-money valuation calculator estimates a startup’s value immediately after a funding round by adding the investment amount to the pre-money valuation. It also helps estimate investor and founder ownership after the round.
Post-money valuation equals pre-money valuation plus new investment. If a company has a $5 million pre-money valuation and raises $2 million, the post-money valuation is $7 million.
Investor equity is the investment amount divided by post-money valuation. For a $2 million investment at a $7 million post-money valuation, investor ownership is about 28.6% before considering option pool or other round terms.
Pre-money valuation is the company value before new funding. Post-money valuation is the value after the investment is added. The distinction matters because it determines how much ownership new investors receive.
No. This calculator focuses on the basic pre-money plus investment calculation and implied ownership split. Term sheets may also include option pool expansion, SAFEs, notes, preferences, and other terms that change dilution.
Use post-money valuation when comparing funding offers, estimating dilution, preparing for investor discussions, or explaining how a round changes ownership between founders and new investors.
