Frequently Asked Questions

Why scenario modeling instead of Monte Carlo simulations?

Monte Carlo gives you probability ranges ("70% chance of success"). For real life planning, you need to model specific high-impact events — "What if there's a 50% crash in Year 3?" or "What if inflation spikes to 8%?" — and build concrete contingency plans. Our deterministic engine gives you actionable conviction, not probability fog.

Where is my data stored?

100% data sovereignty — everything stays in your browser's local storage. Your financial data never touches our servers. You own and control your data completely.

Is FinP4l really free? What's the catch?

Yes, completely free. FinP4l is a public benefit project — no ads, no premium tiers, no selling data.

Can I calculate my FIRE number?

Yes! FinP4l calculates your FI number based on expenses and shows when you'll reach it.
