Financial Planning Shouldn't Require a Finance Degree

Probability Fog

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.

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.
