Loan Repayment Calculator

How Loan Repayments Work

Every loan repayment is divided between two components: principal — the amount that directly reduces what you owe — and interest — the cost of borrowing that money. Early in a loan, a larger share of each payment goes toward interest because the outstanding balance is at its highest. As the balance falls month by month, the interest portion decreases and the principal portion increases. This is called amortization.

Our loan repayment calculator uses the standard amortization formula to give you the exact monthly payment for any loan amount, rate, and term — whether it is a personal loan, car loan, student loan, or consumer credit.

How to Use This Calculator

Enter your loan amount — the total you are borrowing. Add the annual interest rate from your loan agreement. Set the loan term in months — for example, a 4-year loan is 48 months, a 5-year loan is 60 months. Optionally, add an extra monthly payment above the minimum to see how much time and interest you would save by paying slightly more each month. Click Calculate to see your full repayment breakdown.

The Power of Extra Payments

Paying even a small amount above your minimum monthly payment every month can dramatically shorten your loan term and reduce total interest paid. On a €15,000 loan at 6.5% over 48 months, the minimum monthly payment is around €356. Adding just €50 extra per month — bringing the total to €406 — cuts approximately 5–6 months off the loan and saves several hundred euros in interest. Adding €100 extra saves even more.

This works because every extra euro goes directly to reducing the principal balance, which then means less interest accrues in subsequent months. The effect compounds month after month, which is why small extra payments early in a loan have such a significant impact on the total cost.

Types of Loans This Calculator Works For

Personal loans are typically unsecured, ranging from €1,000 to €50,000, with terms of 1–7 years and rates of 5–20% depending on credit profile. Car loans are secured against the vehicle, usually at lower rates of 3–8% over 2–6 years. Student loans vary by country — many have fixed low rates and extended terms. Consumer credit for purchases like appliances or furniture often comes with short terms and high rates if not paid off quickly. Enter the specific figures from your loan agreement for an accurate result.

Frequently Asked Questions

What is APR and how does it differ from the interest rate?

APR (Annual Percentage Rate) is the total cost of borrowing per year expressed as a percentage, including the interest rate plus any mandatory fees. The interest rate alone is the base rate without fees. For this calculator, use the interest rate from your agreement — if you only have APR, use that as an approximation, though the result will slightly overstate the monthly payment if fees were included in the APR.

Can I pay off my loan early?

Most loans allow early repayment, but some charge an early repayment fee — typically 1–2% of the outstanding balance, or up to two months' interest. Check your loan agreement before making a large lump-sum payment. Even with a fee, early repayment can still save money on longer or higher-rate loans.

What happens if I miss a payment?

Missing a payment typically incurs a late fee, may trigger a higher default interest rate, and negatively affects your credit score. Contact your lender as soon as possible if you are struggling to make payments — many lenders offer payment holidays or restructuring options for borrowers in genuine difficulty.

Should I consolidate multiple loans?

Consolidation combines multiple loans into a single loan, ideally at a lower rate. It simplifies management and can reduce total monthly payments, but can also extend your term and increase total interest paid if not carefully compared. Use this calculator to model both scenarios — your current total monthly payments against a consolidated loan — to see which is genuinely cheaper overall.

Tips for Paying Off Loans Faster and Cheaper

Round your payment up to the nearest convenient figure — paying €380 instead of €356 makes a real difference without feeling significant. Put windfalls such as tax refunds, bonuses, or unexpected income directly toward the principal. If you have multiple loans, focus extra payments on the highest-rate loan first (the avalanche method) to minimise total interest, or pay the smallest loan first (the snowball method) for motivational momentum. Avoid taking on new debt while repaying existing loans, and always check whether refinancing at a lower rate makes sense if market rates have fallen since you originally borrowed.
