How hire purchase works
Hire purchase (HP) lets you spread the cost of a car or other goods. You pay a deposit, then fixed monthly payments for the term. The finance company owns the goods until the last payment, including any option-to-purchase fee, is made — then they are yours.
Each payment covers the month's interest on the outstanding balance plus some of the amount borrowed, so early payments are mostly interest and later ones mostly capital. The year-by-year table shows this for your figures.
How this calculator works
- Amount of credit = cash price − deposit.
- Monthly rate = (1 + APR)1/12 − 1. A UK APR is an annual effective rate, so dividing it by 12 would overstate the cost slightly.
- Monthly payment = (credit − final payment ÷ (1 + r)n) × r ÷ (1 − (1 + r)−n), paid at the end of each month for n months. Interest runs on the whole balance, including any final payment, until it is paid.
- Total charge for credit = interest + fees. Total amount payable = cash price + total charge for credit.
Lenders round payments to the penny and may time fees differently, so a quote can differ from these figures by a few pounds.
Your rights under the Consumer Credit Act
For a regulated HP agreement, you can end it at any time before the final payment is due by giving notice (section 99). You may then have to pay the amount by which half of the total price exceeds what you have paid, unless the agreement asks for less (section 100). Once you have paid a third or more of the total price, the goods are "protected" and the finance company needs a court order to take them back if you fall behind (section 90). The calculator shows both thresholds for your agreement.

Official rules this calculator applies
UKCalc assumptions — not official figures
- Payments are equal, monthly and paid at the end of each month; the final payment and option-to-purchase fee are paid with the last month; the documentation fee is paid at the start.
- Fees are added on top of the interest at the APR you enter. If your quote's APR already includes the fees, the true interest rate is lower than that APR.
- Excluded: insurance, servicing, road tax, and any arrears, late-payment or settlement charges.
