Use this free loan repayment calculator online to estimate your monthly repayments, total interest, and overall borrowing cost in pounds sterling. Enter the loan amount, annual interest rate, repayment term, and any extra monthly payment to compare a standard repayment plan with an overpayment scenario.

How Monthly Loan Repayments Are Calculated

For a typical fixed-rate loan with equal monthly payments, each repayment covers interest and reduces the outstanding principal. The monthly payment depends on the amount borrowed, the interest rate, and the repayment term. This calculator estimates the standard monthly payment first, then models how extra monthly payments could change the repayment period and total interest.

How Extra Monthly Payments Can Reduce Interest

Paying extra towards your loan can reduce the outstanding balance faster, which may lower the interest charged in later months. The potential saving depends on your balance, interest rate, payment timing, and lender’s rules. Some agreements restrict overpayments or charge early repayment fees, so check your loan terms before making additional payments.

Compare Loan Terms and Total Borrowing Costs

A longer repayment term can reduce your regular monthly payment but may increase the total interest paid over the life of the loan. A shorter term or additional payments may reduce interest, although the required monthly commitment could be higher. Compare the monthly payment, total interest, and estimated payoff time to understand these trade-offs.

What This UK Loan Repayment Calculator Includes

This calculator estimates repayments for a fixed-rate loan with monthly interest and regular monthly payments. It can also model an additional monthly payment.

The estimate excludes fees, changes in interest rates, lender-specific payment rules, and any early repayment charges. The APR entered is treated as a nominal annual rate divided into monthly rates, so the result may differ from a lender’s APR-based quotation.
