FAQ

Frequently Asked Questions

What should I consider when comparing installment loans?

Always compare the effective annual interest rate, not the nominal rate. Check for hidden fees, flexible repayment options, and whether special repayments are allowed without penalty.

Can I repay an installment loan early?

Yes, since 2010 EU regulations allow early repayment of consumer loans. The maximum prepayment penalty is 1% of the remaining balance (or 0.5% if less than 12 months remain).

Are my entered amounts stored anywhere?

No. All calculations happen exclusively in your browser. Your inputs are never sent to our server or stored. You can safely enter sensitive financial data.

Key Data and Facts

The effective annual rate is the best comparison metric. Typical terms: 12-120 months. Credit-score-dependent rate: the actual rate depends on your SCHUFA score.

Step-by-Step Guide

How to calculate your instalment loan step by step: 1. Set the loan amount: The required net loan amount (e.g. EUR 15,000). 2. Choose the term: A shorter term = a higher instalment, but less interest overall. 3. Enter the interest rate: Distinguish between the nominal interest rate and the effective annual interest rate. The effective annual interest rate includes all costs and is the value used for comparison. 4. Calculate the monthly instalment: Annuity formula or determined by the calculator. 5. Check the total costs: The sum of all instalments = loan amount + total interest. 6. Compare offers: Always use the effective annual interest rate, not the nominal interest rate. Creditworthiness-dependent interest rates can deviate significantly from the advertised rate. Example: Instalment loan of EUR 15,000, 48 months, effective annual interest rate 5.9 %. Monthly instalment: 15,000 x (1.004917^48 x 0.004917) / (1.004917^48 - 1) = EUR 352.37. Total payment: 352.37 x 48 = EUR 16,913.76. Total interest: EUR 1,913.76. Comparison over 84 months (5.9 %): instalment EUR 217.54, total interest EUR 3,273.36 -- EUR 1,360 more interest.

Calculation Example

Instalment loan of 15,000 EUR, 48 months, 5.9 % effective annual interest. Monthly payment: 352.37 EUR. Total interest: 1,913.76 EUR. Over 84 months: payment 217.54 EUR, interest 3,273.36 EUR.
