Loan Repayment Calculator
Annuity and linear repayment with amortization schedule
Enter your loan amount, interest rate, and repayment term to see your monthly payment, total interest, and a detailed amortization schedule. Choose between annuity or linear repayment.
How to use it
Enter your loan details
Fill in the loan amount, annual interest rate (nominal), and repayment term in months.
Choose the repayment type
Annuity — fixed monthly payment throughout the term. Linear — payment decreases as interest shrinks with the remaining balance.
Review the result and schedule
See your monthly payment, total interest, and a month-by-month amortization breakdown.
This calculator uses the nominal annual interest rate (APR). The effective rate includes additional costs — fees, insurance, and charges. To get a realistic picture of your total loan cost, always compare the effective rates across different lender offers.
Frequently asked questions
What is the difference between annuity and linear repayment?
With annuity repayment, your monthly payment stays the same throughout the loan term — more goes to interest at first, then more to principal. With linear repayment, the principal portion is fixed each month, so your total payment decreases over time as interest shrinks.
What interest rate should I enter?
Enter the nominal annual interest rate (APR before fees). This is the basic rate your lender quotes. The effective rate (which includes fees and charges) will be higher.
How does early repayment affect my loan?
Early repayment reduces your remaining balance, which decreases future interest charges. Some lenders may charge a prepayment penalty — check your loan agreement.
Which repayment method costs less overall?
Linear repayment typically results in less total interest paid because your balance decreases faster. However, the initial payments are higher than with annuity repayment.
What factors affect my interest rate?
Your credit score, loan type, term length, currency clause, fixed vs variable rate, and the reference rate (e.g., EURIBOR) all influence the interest rate you receive.
What happens if I make extra payments on my loan?
Extra payments reduce your outstanding principal faster, which lowers the total interest you pay over the life of the loan. Some lenders may charge a prepayment fee, so check your agreement first.
How does the loan term affect total interest paid?
A longer term means lower monthly payments but significantly more interest paid overall. A shorter term costs more each month but saves money in total interest.
What is the difference between APR and interest rate?
The interest rate is the base cost of borrowing. APR (Annual Percentage Rate) includes the interest rate plus additional fees and charges, giving a more complete picture of the loan cost.
What is an amortization schedule?
An amortization schedule is a table showing each monthly payment broken down into principal and interest portions, along with the remaining balance after each payment.
Is a fixed or variable interest rate better?
Fixed rates provide payment predictability throughout the loan term. Variable rates may start lower but can increase over time as the reference rate changes. The best choice depends on your risk tolerance and market conditions.
