SAFE Conversion Formula
Transparent mathematical methodology explained in plain English.
Conversion Price = Min[ Valuation Cap / Post-Money Shares, Priced Round Price × (1 - Discount Rate) ]Determines the effective price per share when a SAFE or convertible note converts into preferred shares at a qualified priced round.
Variables Explained:
- SAFE Investment ($): Principal capital invested via SAFE note.
- Valuation Cap ($): Maximum valuation at which the investment converts into equity.
- Discount Rate %: Percentage discount on next round priced share price (typically 20%).
$250,000 SAFE with $5,000,000 Post-Money Cap Converting in Series A ($15M Valuation)
Calculating SAFE conversion ownership percentage.
- Post-Money SAFE Ownership Formula: Investment / Valuation Cap.
- Calculate Ownership: $250,000 / $5,000,000 = 5.00%.
- Series A Value of SAFE Stake: 5.0% of $15,000,000 = $750,000 (3.0x return on paper).

What is the difference between pre-money and post-money SAFEs?
Y Combinator's Post-Money SAFE (introduced in 2018) locks in the exact ownership percentage at the time of investment (Investment / Cap), making dilution fully predictable before priced rounds.
What happens if a priced round is below the valuation cap?
If the Series A valuation is lower than the valuation cap, the SAFE investor benefits from the discount rate (e.g. 20% discount on the lower priced round share price).
