Startup math, done transparently
Free calculators for founders, angels and employees. Every formula is explained on the page, and everything runs locally in your browser.
Liquidation waterfall
Who gets what at exit: multiple preferred series, 1x/2x preferences, participation with caps, seniority vs pari passu, and the convert-or-take-preference decision.
SAFE conversion
Post-money and pre-money SAFEs with valuation cap, discount and MFN, converting into a priced round with an option pool top-up. Cap table before and after.
Round dilution
Round size, pre-money valuation and the option pool shuffle: price per share, new shares and post-money ownership.
Disclaimer: These calculators are simplified educational models, not legal, tax, investment or financial advice. Real outcomes depend on the exact wording of your charter, SAFE, side letters and shareholder agreements (e.g. rounding, dividends, anti-dilution, carve-outs, escrow, fees). Always verify with a qualified lawyer or advisor before relying on any figure. No data you enter leaves your browser.
