SAFE Note Estimator
Estimate equity conversion from a SAFE note with valuation cap and discount.
The valuation cap sets a ceiling on the price the SAFE investor pays per share. If the company's valuation at conversion exceeds the cap, the SAFE investor converts at the cap, getting more shares for their money. The discount rate gives the investor a percentage reduction on the price per share paid by the new round's investors. At conversion, whichever mechanism produces a lower effective price, and therefore more equity, is the one that applies.
This SAFE Note Estimator models the conversion math so both founders and investors can see the outcome before the priced round happens. You enter the SAFE investment amount, the valuation cap, the discount percentage, and the expected pre-money valuation at the time of conversion. The tool calculates the ownership percentage under both the cap and discount scenarios, selects the better deal for the investor, and shows the effective valuation and effective discount.
Understanding these numbers early prevents friction during conversion. Founders sometimes discover that a low valuation cap combined with a steep discount produces far more dilution than they anticipated. Running the numbers in advance lets you negotiate SAFE terms that both parties find reasonable.
Whether you are a founder about to sign your first SAFE or an angel investor evaluating a deal, this estimator gives you immediate clarity on what the conversion will look like under different valuation scenarios.

FAQ
What happens if the valuation cap and discount produce different results?
The SAFE investor gets whichever mechanism produces a better deal for them, meaning whichever results in a lower effective share price and therefore a higher ownership percentage. If the valuation cap produces a lower price per share than the discount, the cap governs. If the discount produces a lower price, the discount governs. They never stack on top of each other.
Can a SAFE have only a cap or only a discount?
Yes. Some SAFEs include only a valuation cap with no discount, and others include only a discount with no cap. Cap-only SAFEs are common in hot markets where founders have leverage. Discount-only SAFEs are less common but do exist. This tool handles both scenarios. Set the discount to zero for a cap-only SAFE, or set the cap very high for a discount-only SAFE.
How does a SAFE differ from a convertible note?
A SAFE is not debt. It has no interest rate, no maturity date, and no repayment obligation. A convertible note is a loan that accrues interest and must be repaid or converted by a maturity date. SAFEs are simpler and faster to execute, which is why they dominate early-stage fundraising. Convertible notes are still used in some markets and by investors who prefer the additional protections that debt instruments provide.
