Valuation before/after a funding round. The Pre/Post-Money Valuation Calculator takes investment amount, pre-money valuation and returns post-money valuation plus investor ownership, existing holders after the round. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Startup metrics are about the efficiency of growth: how much it costs to win and keep customers, how fast recurring revenue compounds, and how long the cash lasts. Investors read these numbers before they read the pitch. Use the worked example below to check the maths against your own figures.
How the Pre/Post-Money Valuation Calculator works
A $2 million investment at an $8 million pre-money valuation gives the investor 20% of a $10 million company. Always clarify whether a quoted valuation is pre- or post-money.
Worked example
With the example values (investment amount of $2,000,000, pre-money valuation of $8,000,000), the post-money valuation is $10,000,000.00; investor ownership 20%, existing holders after the round 80%. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.
