Frequently Asked Questions
What is the difference between nominal and effective interest rate?
The nominal rate is the pure interest rate. The effective APR (EJZ) includes all costs and is always used for comparison. German law requires the APR to be stated.
What is the maximum monthly payment I should aim for?
Rule of thumb: the loan payment should be max. 10–15 % of net income. At 2,000 EUR net that is 200–300 EUR. Higher payments are possible but reduce financial flexibility significantly.
Are extra repayments worth it?
Yes – they reduce the outstanding balance directly and thus future interest. Many banks allow up to 5–10 % of the loan amount annually without penalty. An extra payment of 1,000 EUR can shorten the term by months.
When can I repay a loan early?
For consumer loans under 7,500 EUR: anytime, free of charge. For larger amounts: early repayment fee max. 1 % (remaining term > 1 year) or 0.5 % (< 1 year). Mortgage loans can be cancelled after 10 years with 6 months notice.
What is the Consumer Loan Calculator?

How does the Consumer Loan Calculator work?
Enter loan amount, term and nominal interest rate. The calculator uses the annuity formula to compute the monthly payment, total interest and effective APR. An optional amortisation schedule shows how debt and interest evolve month by month.
