How do you calculate hire purchase interest?

To calculate hire purchase interest, first determine the total cost of the item and the deposit amount. Subtract the deposit from the total cost to find the financed amount. Next, apply the interest rate, typically expressed as an annual percentage rate (APR), to the financed amount over the repayment period to calculate the total interest. Finally, add the interest to the financed amount to determine the total amount payable over the hire purchase term.
