PCP vs HP vs leasing: which way to finance a car is cheapest?

HP (hire purchase) spreads the whole car price over the term. PCP (personal contract purchase) defers a chunk of it — the guaranteed minimum future value (GMFV) — to an optional final balloon payment, which is why the monthlies are lower. Leasing is long-term rental: you only ever pay for depreciation and interest, and you never own anything.

A £25,000 car over 4 years — £2,500 deposit, 9.9% APR on the finance, £10,000 GMFV on the PCP, a £320-a-month lease (9 months’ initial rental), and an £11,000 resale value at the end:

True cost = everything you paid minus the value you keep. Notice the inversion: the lease has the lowest monthly (£320) and beats HP on true cost here, while the PCP — the mid-priced monthly — is the most expensive way to end up owning this particular car, because you pay interest on the deferred balloon all term. Your numbers will differ: run them through the calculator, which ranks all the options for your actual deal.

A PCP splits the car into two parts: what you pay monthly (deposit + the gap between price and GMFV, plus interest on the whole balance) and the balloon at the end. Then you choose:

1. Hand the car back — walk away, subject to mileage and condition charges;
2. Pay the balloon and keep it — often by refinancing the balloon, which adds yet more interest;
3. Part-exchange — if the car is worth more than the GMFV, the difference (“equity”) becomes the deposit on the next PCP. This is the dealer’s favourite ending, and why PCP customers often roll from deal to deal indefinitely.

The key insight: you pay interest on the full amount owed — including the balloon you might never pay off. That’s the price of the flexibility.

• Mileage penalties — PCP and lease deals charge per excess mile (commonly 5–15p+). 4,000 miles over at 10p is £400; understating your mileage to lower the quote always backfires.
• Condition charges — “fair wear and tear” is defined by the finance company, not you; scuffed alloys and dents are billed at hand-back.
• Negative equity — if the car is worth less than you owe mid-contract, changing cars means rolling the shortfall into the next agreement.
• Gap insurance upsells — worth considering on PCP (an insurance write-off pays market value, which can be less than you owe), but shop around rather than buying at the dealer’s counter.
• Voluntary termination — under the Consumer Credit Act you can usually return an HP or PCP car once half the total amount payable has been paid; useful escape hatch worth knowing before you need it.

• Buy with cash (or mostly cash) if you can — it’s almost always the lowest true cost, and our example shows why: £14,000 versus £17,900–£21,600 financed.
• HP if you want to own the car and keep it well beyond the finance term — highest monthlies, but every payment builds towards ownership and there are no mileage rules.
• PCP if you value flexibility or change cars every 2–4 years — just judge it on total cost including the balloon, not the showroom monthly.
• Leasing if you’re happy never owning: predictable motoring costs, often including road tax, and no resale risk — but nothing to show at the end and strict limits throughout.

Whatever the route, compare the APR and the total amount payable on the finance agreement — dealers make more margin on finance than on many cars, and a personal loan plus a cash purchase sometimes beats all three.
