The total paid under hire purchase terms generally results in a greater overall price for the item than its original sale price. The extra amount paid is again called interest and is expressed as a percentage rate per annum. The advantage of paying under hire purchase terms is that the customer has the use of the item whilst still paying it off; the disadvantage is that often you will pay much more than the original price in the long term.1.
