SAFE cap vs discount: which wins (with conversion example)

TL;DR outcome

• The SAFE converts at the lower price: valuation cap or discounted price.
• In the base case, the cap wins once pre-money rises above $10M.
• Ownership impact moves more with pre-money valuation than with discount tweaks.

The situation

You have a SAFE with both a valuation cap and a discount. The question is simple: which term actually sets the conversion price at the priced round?

Inputs that matter (and which ones do not)

Matters most

• Valuation cap.
• Discount rate.
• Pre-money valuation at the priced round.

Does not matter here

• Board size, liquidation preferences, or pro-rata rights.

Interactive model

Breakpoints / inflection points

The breakpoint table shows the pre-money valuation where the cap price equals the discount price. Above that valuation, the cap drives the conversion.

Worked example (numbers)

What changes if...

• Cap is raised: the discount wins more often, increasing the conversion price.
• Discount increases: the break-even cap point shifts higher.
• Pre-money jumps: the cap dominates, boosting SAFE ownership.

Common mistakes

1. Using post-money valuation for the discount calculation.
2. Assuming the cap always applies even at modest valuations.
3. Forgetting the new money in the priced round when calculating ownership.

Checklist / next steps

• Confirm whether the SAFE is pre-money or post-money (this model is pre-money).
• Ask for the priced-round term sheet to verify the pre-money.
• Use the Convertible Calculator for stacked SAFEs and convertible notes.
