Financial calculators that use your country's actual rules

Most calculators run one formula and change the currency symbol. Ours apply each country's real repayment conventions, current reference rates and local costs — so the number you see is the one you'd actually pay.

Choose your country

Repayment maths genuinely differs. Canadian fixed-rate mortgages compound semi-annually. German mortgages leave a balance outstanding when the fixed period ends. Pick a country and we apply the right rules.

Official sources. Reference rates come from central banks and national statistics agencies, with the source and date shown on every page.

Open methodology. Every formula is published, with worked examples you can check.

No lead capture. No email, no quote form, no broker handoff. The calculator just works.
