The discount rate on a convertible note or SAFE gives the early investor a built-in price break when the instrument converts into equity at the next priced round. A 20% discount means the holder converts at 80% of the new investors’ price per share.
The discount compensates early backers for taking risk before a valuation is set. Where an instrument has both a discount and a valuation cap, conversion usually applies whichever gives the investor the lower (more favorable) price.
How the discount interacts with the cap
The discount rate on a convertible rewards early investors for taking risk before a price is set: at the next priced round their money converts at, say, 20% below the round price, buying them more shares per dollar. The subtlety is its interaction with a valuation cap. When a note carries both, the investor almost always converts at whichever gives the lower effective price — the cap in a strong up-round, the discount in a modest one. Founders should therefore model both mechanisms together, not in isolation, because a generous discount stacked on a low cap can hand early investors a much larger stake than the headline numbers suggest.
Discount reads together with the cap
The discount alone is half the information: convertible instruments typically carry both a discount (10–25% band) and a valuation cap, and the investor converts at whichever is better. The practical consequence: in companies gaining value quickly, the cap nearly always sets the price, while the discount protects flat scenarios. Founder modelling discipline: for every new instrument, compute “cap or discount — which binds?” across bad/base/good round scenarios, and view cumulative dilution where instruments stack. In Turkish-law convertibles, writing the formula into the contract with a numerical worked example — discount, cap, which applies — is the cheapest preventer of conversion-day arithmetic disputes.
