Car finance and the real cost of ownership

Set an all-in budget

Write down the deposit or cash price, monthly payments, insurance, vehicle tax, fuel or electricity, servicing, tyres, parking and a repair allowance. Get an insurance quote for the actual registration. Leave a cash reserve instead of spending every pound on the purchase.

A lower monthly payment can hide a longer term, higher interest cost or a large final payment. Compare the total amount payable, not just the amount due each month.

Know what each payment method means

Cash means no borrowing interest but less money left in savings. With a personal loan you normally buy the car outright and repay the lender separately. With hire purchase (HP), you make payments under a finance agreement and ownership passes at the end when its terms are met.

Personal contract purchase (PCP) normally has a deposit, monthly payments and an optional final payment if you want to keep the car. Returning it can trigger charges for mileage or condition under the agreement. Personal contract hire (PCH) is a lease: you normally return the car and do not own it.

Ask for the numbers in writing

For each quote, record the cash price, deposit, term, APR, every fee, total amount payable and any final payment. For PCP or leasing, also record annual mileage, excess-mileage charges, condition rules and your end-of-contract choices. Compare quotes using the same deposit and term.

Ask whether warranty, gap insurance, paint protection or servicing products are optional and what each adds to the total. Read early-settlement and missed-payment terms before signing. If the figures on the final agreement differ from the quote, stop and ask why.

• Check the final payment is affordable if you expect to keep the car.
• Keep the pre-contract information and signed agreement.
• Do not treat a predicted future car value as guaranteed.

Recheck costs before paying a deposit

Insurance quotes, fuel prices, charging prices and tax rules change. Recalculate with current figures for the exact car and your circumstances. If you are comparing an EV with a petrol car, use the electricity price you will actually pay at home or on public chargers, not an assumed cheap tariff.

If the budget only works when nothing breaks, look at a less expensive car. A service history reduces uncertainty but does not remove the need for maintenance.
