TLDR:
A conversion discount gives convertible note or SAFE holders the right to convert their investment into equity at a lower price per share than what new investors pay during a subsequent financing round.
How Conversion Discounts Work in Practice
If an investor puts $100,000 into a SAFE with a 20% conversion discount and the company later raises a Series A at $1.00 per share, the SAFE investor would convert at $0.80 per share (20% discount), receiving 125,000 shares instead of 100,000 shares — 25,000 more shares than a Series A investor investing the same amount.
Typical Discount Ranges
Conversion discounts typically range from 10% to 25%, with 20% being the most common. The discount represents compensation to the early investor for taking risk before the company was priced. A larger discount is often paired with a more founder-friendly valuation cap, or vice versa — sophisticated investors and founders model the combined economics across different exit scenarios.
Discount vs. Cap Mechanics
When a SAFE has both a cap and a discount, conversion happens at whichever produces a lower effective price (more shares for the investor). In a high-valuation priced round, the cap is typically more favorable; in a modestly-priced round, the discount may apply. Some SAFE structures specifically offer “Most Favored Nation” terms allowing the early investor to take the better of these mechanisms based on later SAFE rounds.
Tax and Reporting Considerations
The discount embedded in a convertible note may be characterized as original issue discount (OID) for US tax purposes, requiring imputed interest accrual. Founders and finance teams should coordinate with tax counsel when issuing convertible instruments to avoid surprises at conversion.
