Loan calculator — work out your monthly payment online
Our free loan calculator works out the monthly instalment, total interest, and total repayment amount for a mortgage or personal loan in seconds. Enter the amount, nominal annual interest rate, and loan term, then choose a repayment type — fixed or decreasing instalments. You can also add the bank's fee to see the full cost of the loan. Results appear instantly, no sign-up required.
Repayment schedule — principal and interest instalment by instalment
Below the results you will find a full repayment schedule: for each instalment we show the payment amount, the principal portion, the interest portion, and the remaining balance. This makes it easy to see how quickly your debt is reducing and how much of each payment goes to interest alone. The first instalments are shown immediately, and you can expand the full schedule with a single click.
Frequently asked questions
- What is the difference between fixed and decreasing instalments?
- With fixed (annuity) instalments you pay the same amount every month for the entire term — early payments are mostly interest, later ones mostly principal. With decreasing instalments the principal portion is constant, so the first payment is the highest and each subsequent one is lower. Decreasing instalments usually result in less total interest paid, but require a higher credit capacity at the start.
- Does the calculator include APR?
- No. The calculator shows the instalment and interest based on the nominal annual rate you enter. APR additionally includes fees, insurance, and other time-distributed costs, so the actual cost at a bank may be higher. Treat the results as indicative only.
- Is my data secure?
- Yes. All calculations run entirely in your browser. The loan amount, interest rate, and any other data are never sent to a server or stored anywhere.
- What should I enter in the interest rate field?
- Enter the nominal annual interest rate of the loan as a percentage (e.g. 7.5). The calculator will convert it to a monthly rate and spread it across the number of instalments. If you set the rate to 0, the instalment will simply be the loan amount divided by the number of months.
