Fincal is a free loan and compound-interest calculator that turns your numbers into clear answers and charts — and keeps everything private on your device.
Compare equal-principal, equal-instalment, and flat-rate loans side by side — and see the real effective rate, so a “low” flat rate can't fool you.

Handle interest rates that change over time, add early repayments, and instantly see how much time and money you save.

Project compound growth with regular contributions and a clear year-by-year breakdown.

Every calculation is saved automatically, so you can reopen and tweak it anytime.

Keep favourite setups as named scenarios and compare them side by side — all fully offline, no account, your amounts never leave your phone.
