Assumes burn stays flat and revenue compounds at the rate above. Funding rounds rarely land exactly — 15–25% buffer is healthy.

FAQ
What buffer % should I use?
15–25% is healthy. Rounds slip, hires take longer than planned, and revenue lands later than your model — buffer absorbs that.
Why does dilution feel high?
Dilution = raise ÷ (pre-money + raise). A bigger raise at the same pre-money means more dilution; raising less or pushing pre-money up are the two levers.
