Frequently asked questions
How do I calculate my Stripe option value?↓
Enter your number of vested shares, your equity type (ISO or NSO), and your strike price. The calculator computes the in-the-money value using secondary market data, then runs three additional methods. The most important output: Method B (secondary-implied) minus your strike price = your estimated intrinsic value per share.
Should I wait for the Stripe IPO to exercise options?↓
Generally, waiting for the IPO is lower risk — you exercise and immediately sell at the public market price. The downside: you miss the long-term capital gains clock. If your options have a low strike price and a long expiration window, early exercise may save significant taxes. Consult a CPA.
