FIRE: Retirement Calculator

Support

A retirement countdown and FIRE calculator whose Home Screen widget counts down to the day your investments are projected to reach financial independence.

How is my FIRE number calculated?

Your FIRE number is your annual retirement expenses divided by your safe withdrawal rate (for example, $40,000 ÷ 4% = $1,000,000). The countdown projects when your current investments, growing at your assumed return and topped up by your yearly contributions, are expected to reach that number. Tap "How this is calculated" on the Plan tab to see the math with your own figures.

Is this financial advice?

No. The app provides educational estimates only. Projections are illustrative and are not guarantees or personalized investment advice.

How does the free trial and Pro work?

You get full access to every Pro feature free for the first 14 days. After that, the core app — your FIRE number, the countdown, the standard widget, and your growth chart — stays free forever. Pro is a one-time purchase that unlocks the advanced tools for good; there is no subscription and nothing auto-renews.

I bought Pro — how do I restore it on a new device?

Open Settings in the app and tap Restore purchases. Your one-time unlock is tied to your Apple ID and will be restored at no charge.

How do I add the Home Screen widget?

Touch and hold your Home Screen, tap the + in the corner, search for "FIRE", and add the widget. Pro unlocks extra widget styles and per-goal widgets.

Is my data private?

Yes. Everything you enter stays on your device — no account, no tracking, no network. See our Privacy Policy.
