FAQ
Frequently Asked Questions
What is an amortisation schedule?
An amortisation schedule shows how the payments split into interest and principal and how the remaining balance falls. This calculator works month by month internally and sums the schedule per year: opening balance, interest, principal, extra repayment and balance at year end. It helps understand total loan costs and plan extra payments.
What initial repayment rate is recommended?
Experts recommend at least 2–3 %. At 4 % interest, full repayment takes just over 40 years with 1 % repayment, about 27.5 years with 2 % and only about 21 years with 3 %.
What are extra repayments?
Extra repayments are payments beyond the regular instalment. They reduce the outstanding balance immediately and thus future interest payments. Many loans allow up to 5–10 % of the loan amount p.a. penalty-free.
What is the difference between annuity and instalment loan?
Annuity loan: constant payment, falling interest share, rising principal share. Instalment loan: constant principal + falling interest = falling total payment. The instalment loan has lower total interest but a higher initial burden.

What is the Amortization Calculator?
The amortisation calculator creates a full repayment schedule for annuity loans and shows how interest, principal and remaining debt evolve over the entire term.
How does the Amortization Calculator work?
Enter loan amount, interest rate, initial repayment rate and, optionally, an annual extra repayment. The monthly payment is loan × (rate + repayment) ÷ 12. The calculator works month by month: interest portion = remaining debt × monthly rate; principal portion = payment − interest; new remaining debt = old debt − principal. The schedule sums the months per year.
Key Data and Facts
Annuity loan: constant payment, falling interest share, rising principal share. Initial repayment 2 % at 4 % interest: term approx. 28 years. Annual overpayment of 5 % can shorten term by several years. Early repayment penalty possible before fixed-rate end.
Step-by-Step Guide
Step-by-step: 1. Enter loan amount and interest rate. 2. Choose repayment rate (min. 2 % recommended). 3. Calculate monthly payment: payment = loan × (rate + repayment) ÷ 12. 4. Read the year-by-year amortisation schedule. 5. Plan overpayments to save on interest. 6. Remaining debt for refinancing: read it in the row of the last year of your fixed-rate period.
Calculation Example
Loan 200,000 EUR, 3.5 % interest, 2 % repayment: payment 200,000 × 5.5 % ÷ 12 = 916.67 EUR/month. Month 1: interest 583.33 EUR, principal 333.33 EUR. After 10 years: remaining debt approx. 152,189 EUR, interest paid approx. 62,189 EUR (120 payments = 110,000 EUR, of which 47,811 EUR principal).
