Hire purchase is used when someone cannot afford to buy the item; a deposit is usually paid and the balance is paid over a fixed period of time.
A customer is usually required to pay a deposit. From there, the interest is charged onto the balance that is owed and this is then divided into equal instalments which are paid over a fixed period of time.
We use the simple interest formula for this calculation.
An electronics company offered a $1,200 television to the purchaser where a deposit of $100 was provided upfront with the balance to be paid over 18 equal monthly instalments. Interest is charged at 12.4% p.a. flat rate.

Deposit =
Use this information to calculate the balance of the loan.

Now write the balance () and additional information we were provided with- making sure that the rate and time are in the same units.

Use the simple interest formula to calculate the amount of interest.
Total interest paid will be $204.60.
b) Calculate the repayment value.
First, find the total repayment amount (not including the deposit).
Total repayment = interest + principal
Total repayment =
Total repayment =
To calculate the repayment amount, take the total amount and divide it by the number of repayments.
Repayment =
Repayment = $72.477$
The regular monthly instalments are $72.48.
c) What is the total cost of the television?
To find this amount, add the marked price with the interest amount.
Total cost =
Total cost =
The total cost of the television is $1,404.60.
