buy once, own forever
FIRE Model
Will your money last — and what changes it.
Somebody has told you a number you are supposed to retire on, and nobody has shown you the working. This runs your actual plan through thousands of possible futures and tells you the odds it survives, the year it breaks if it does not, and which two changes move that the most.
Under half a minute of FIRE Model being used, recorded through its own interface. Nothing is drawn for the advert and there is no voice-over — every word in it is a word the app itself puts on the screen.
- Included: Web app + installable app
- Included: Every future update included
- Not included: No device-to-device sync in this version

One payment. No subscription, no trial to forget to cancel — the demo on the product page is the real app, so you already know what you're buying.
Not ready to commit? Rent it.
$63/week, cancel anytime. It is worse value on purpose — four weeks costs more than owning it outright, and rent doesn't count toward the purchase. Rent 5 weeks and we'll knock 50% off the lifetime price.
