About All Financial Calculators

What we do

All Financial Calculators gives you straightforward tools to answer everyday financial questions — from working out a loan repayment to projecting investment growth to understanding how inflation erodes purchasing power. Every result comes with the formula, assumptions and methodology used, so you always know exactly how the number was calculated.

Why we built it

Most financial calculators online are either locked behind accounts, cluttered with ads, or built for one specific country. We wanted something universal — tools that work with any currency, any rate, any financial system — and transparent, where the maths is never a black box.

Our principles

• 1 Universal by default. No currency presets, no country-specific tax rules, no regional defaults baked in. All inputs are yours to define.
• 2 Transparent maths. Every calculator shows the formula it uses, the assumptions it makes, and the limits of its results.
• 3 Free forever. No accounts, no subscriptions, no ads blocking your results. Just tools that work.
• 4 Results are estimates, not advice. Our calculators are educational tools. They help you understand numbers and explore scenarios — they are not a substitute for professional financial advice.

What's coming

Phase 1 covers 25 essential universal calculators. Later phases will add advanced personal finance tools, property and insurance calculators, and country-specific calculators for income tax, pension schemes, and more — built carefully with the correct local rules for each jurisdiction.
