Loan Repayment Calculator
Calculate monthly loan repayments and total interest. Repayment or interest-only. Early overpayment savings calculator included.
How to use
Enter your loan details
Enter the loan amount, interest rate and term. For a personal loan or car loan, choose Repayment — payments cover both interest and principal. Interest-only loans charge only the interest each month, with the full balance due at the end.
Early repayment calculator
Use the slider to see how much you'd save in total interest by overpaying each month. Even small regular overpayments can save hundreds in interest and shorten the loan term significantly. Always check your lender allows overpayments without a penalty.
