Loan cost formula

A lower monthly payment is not always the cheapest option. A longer loan term can reduce the amount you pay each month, but it usually increases the total interest paid. Always compare the total repayable amount as well as the monthly figure.

Loan repayments are based on the amount borrowed, the interest rate and the term. Actual lender quotes can vary because APR, fees, early repayment rules and credit checks may change the final cost.
