Calculators — Finance

Finance calculators: loan instalment, flat tax, health contribution, leasing. Calculate in a minute.

Note: banks and offers vary

Some calculators in this category (loan, leasing) are indicative. Interest, fees, insurance and APRC depend on the specific bank or leasing company — each institution has different terms. The result is for estimation; check the actual offer with your chosen bank or lessor.

Other calculators (lump-sum tax, JDG health contribution, PCC, gift tax) are based on uniform regulations (MF, ZUS) — rates and thresholds are the same for everyone.
