Free calculators

Do the maths before you decide.

Salary, tax, savings, loans and pensions: every calculator uses the figures for 2026, shows how it calculates and runs entirely in your browser. Nothing is stored or transmitted.

Salary & tax

Net salary, hourly wage and the main taxes for employees, investors and the self-employed.

Trade tax calculator

Calculate trade tax (Gewerbesteuer): trading income, €24,500 allowance, 3.5% base rate, your municipal multiplier and the income tax credit under § 35 EStG.

Saving & investing

How money grows over the years, what inflation leaves of it and how long a lump sum lasts.

Savings calculator

Savings calculator for regular and ETF savings plans: final balance with compound interest, deposits, interest, annual increases and inflation – year by year.

Interest calculator

Compound interest calculator: final balance and interest on a lump sum with annual, quarterly or monthly crediting, including the effective annual rate.

Loans & property

Monthly instalment, outstanding balance and the additional costs of buying a property.

Loan calculator

Loan calculator for annuity loans: monthly instalment, balance after the fixed-rate period, interest costs, term and repayment plan, with special repayments.

Pensions & protection

Get a realistic picture of your pension gap, occupational disability pension, term life insurance and contents insurance.

The results are non-binding estimates for guidance only and do not replace tax, legal or investment advice. What counts are your payslip, your tax assessment (Steuerbescheid) and the terms of your contracts.
