Finance and tax calculators
Work out mortgage payments, loan interest, savings growth, income tax and VAT with calculators that show the full schedule, not just a single number.
About Finance & tax tools
Money questions rarely have one answer. A mortgage quote depends on the term as much as the rate; a savings plan depends on how often interest compounds; a tax bill depends on allowances that change every April. The calculators in this category are built around those details.
Each one shows its working: amortisation tables you can export, interest-versus-capital charts, and the tax year and thresholds used. Where a rule is country-specific — UK stamp duty, German Umsatzsteuer, Turkish gelir vergisi — the tool says so and links to the official source.
Choosing the right calculator
- Borrowing: start with the mortgage or loan calculator, then use the affordability and overpayment tools to test scenarios.
- Saving and investing: compound interest, savings goal and inflation tools show real (after-inflation) outcomes.
- Tax: pick the calculator for your country so the bands, allowances and social contributions are right.
- Everyday money: VAT, percentage, tip and currency tools handle the quick checks.
Frequently asked questions
Are these calculators suitable for a mortgage application?
They produce the same arithmetic a lender uses for repayment schedules, but lenders add product fees, stress-test rates and their own affordability rules. Treat our figures as an accurate estimate for planning.
Which tax year do the tax tools use?
Each tool shows the tax year selector and states the default. Where a country changes rates mid-year, both sets are available.
