Frequently asked questions
Can I cancel at any time?
Yes. Cancel from your account page anytime. Access continues through the end of the annual period you paid for.
What happens when my subscription expires?
The ISO Planner and RSU Calculator become inaccessible. The AMT Calculator's free mode stays available — no data is deleted.
Do I need an account for the free calculator?
No. The free AMT Calculator is fully accessible without signing in. An account is only needed for premium features.
Is my payment information stored here?
No. All payment processing is handled by Stripe. We never see or store your card details.
Is it worth it?
If you have ISOs across multiple grants or RSUs vesting in a high-tax state, almost certainly. A single good exercise decision from the ISO Planner typically saves far more than $99.
