Frequently Asked Questions

Are these financial calculators really free?
Yes — every calculator on this page is completely free, with no paywall, no premium tier, and no usage limits. They're maintained as part of the free My Financial Freedom Tracker app, so there's no catch hidden inside the tools.
Do I need an account or email to use them?
No. All eight calculators run directly in your browser without registration, email, or credit card. If you want to track your progress over time, you can optionally create a free account in the app.
Which free FIRE calculator should I start with?
Start with the FIRE Planner to find your overall FIRE number and timeline. Then use the Coast FIRE Calculator to see when you could stop saving, and the Barista FIRE Calculator if part-time work is part of your plan.
How accurate are the calculations?
Each calculator uses the same calculation engines as the full My Financial Freedom Tracker app, including inflation adjustment and Monte Carlo simulation where it matters. Results are projections based on your assumptions, not financial advice — small changes in return or inflation assumptions can shift outcomes significantly.
Can I save my results?
The calculators themselves don't store anything — your inputs stay in your browser. If you want to go further, create a free account: the app uses the same calculation engines, so you can rebuild your plan in minutes and track it against your real numbers.

Why are these calculators free?

My Financial Freedom Tracker is built by a developer on his own FIRE journey, and the calculators run on the same engines as the app. Keeping them free, with no sign-up, is the best demo of what the full app can do — if a tool helps you, you might stick around for budgeting, net worth tracking, and the complete FIRE planner.
