PCP vs HP vs Personal Loan: The Cheapest Way to Finance a £25,000 Car
PCP vs HP vs personal loan on a £25,000 car: monthly payments, total cost, ownership and mileage limits compared, with the maths behind every figure.
By Jonathan Pimperton, ACA-qualified accountant Published
The Verdict
On a £25,000 car over four years, the personal loan is the cheapest way to end up owning it — £27,666 all-in against £29,325 on HP and £30,280 on PCP with the balloon paid. PCP only wins if you treat it as renting: £370 a month is the lowest payment on the table, but the car goes back unless you find £10,000 at the end. Decide whether you're buying the car or buying the payment, then compare total amount payable — not APRs or monthlies.
| Feature | PCP | HP | Personal Loan |
|---|---|---|---|
| Monthly payment | £370 — lowest | £559 — highest | £524 |
| Total cost to own the car | £30,280 (incl. £10,000 balloon) | £29,325 | £27,666 — lowest |
| Total interest paid | £5,280 | £4,325 | £2,666 |
| Who owns the car | Lender, until you pay the balloon | Lender, until the final payment | You, from day one |
| Mileage limits | Yes — excess-mileage charges apply | None | None |
| Flexibility | Return, refinance, or keep at the end | Fixed term; can settle early | Sell the car or repay whenever |
| Best for | A new car every 3–4 years | Owning, with dealer convenience | Lowest total borrowing cost |
The same car, three very different bills
Take a representative deal: a £25,000 car, a £2,500 deposit, and 48 months to pay. The dealer offers PCP at 7.9% APR with a £10,000 balloon (the GMFV — 40% of the car’s value), or HP at 8.9%. Your bank offers a personal loan at 5.6% for the same £22,500. Standard loan amortization gives these numbers:
| Monthly | Total paid | Interest | |
|---|---|---|---|
| PCP (keep the car) | £370.41 | £30,279.61 | £5,279.61 |
| HP | £558.85 | £29,324.59 | £4,324.59 |
| Personal loan | £524.30 | £27,666.24 | £2,666.24 |
Three routes to the same driveway, with £2,613 between the cheapest and the most expensive. The gaps come from two things: the APR, and — in PCP’s case — how long the money stays borrowed.
Why PCP’s low payment costs the most
PCP’s £370 monthly payment looks unbeatable, and it’s the reason over 80% of new UK cars are financed this way. The payment is low because you only repay the car’s depreciation — £12,500 of the £22,500 borrowed — while the £10,000 balloon waits until the end.
The catch: interest runs on the full £22,500 for the whole term, including the balloon you’re not paying down. That’s why PCP generates £5,280 of interest against HP’s £4,325 at a lower APR (7.9% vs 8.9%). The deferred £10,000 sits there accruing interest for four years.
If you hand the car back instead of paying the balloon, you’ll have spent £20,280 (deposit plus 48 payments) for four years of driving — about £422 a month all-in. That’s not a bad deal for always driving a car under warranty; it’s just renting, not buying. Be honest with yourself about which one you’re doing.
HP: ownership on the dealer’s forecourt
Hire purchase is the straightforward middle option: repay the whole £22,500 plus interest over 48 months, and the car is yours after the final payment. No balloon, no mileage limits, no condition inspections.
At 8.9% APR the monthly payment is £558.85 — the highest of the three — and the total is £29,325. HP’s weakness is purely the rate: dealer HP typically prices 2–3% above a best-buy bank loan. Its strength is availability — HP is often easier to get than an unsecured loan for the same amount because the car secures the debt, and it can be arranged in an afternoon at the dealership.
The personal loan: cheapest ownership, from day one
Borrow £22,500 at 5.6% over 48 months and the payment is £524.30 — about £35 a month less than HP — with a total cost of £27,666. That’s £1,658 cheaper than HP and £2,613 cheaper than PCP-and-keep, purely because banks price unsecured personal loans more keenly than dealers price car finance.
You also own the car outright from day one. There’s no mileage cap, you can sell whenever you like, and the debt isn’t secured on the car. The trade-offs: the best advertised rates need a strong credit score, and the loan appears in full on your credit file, which can matter if you’re about to apply for a mortgage.
How to choose
- Want the lowest total cost of owning? Personal loan, if your credit score gets you a competitive rate. Run the exact deal through the Car Finance Comparison Calculator — it compares all three plus a cash purchase, including the opportunity cost of your deposit.
- Want a new car every three years and never plan to own? PCP — but compare the monthly cost including deposit against leasing before signing, and watch the mileage allowance.
- Want to own, but the loan rates you’re offered are poor? HP. Fixed payments, guaranteed ownership, no balloon risk.
- Negotiate the car price first, finance second. Dealers make margin on both, and a discounted price on 0% finance is sometimes recovered through a higher sticker price.
Whatever you pick, judge the deal on total amount payable — the Loan Amortization Calculator shows month-by-month how much of each payment is interest, which makes the comparison obvious.
Common questions
Is PCP cheaper than HP?
Monthly, yes — totally, no. On our £25,000 example, PCP costs £370 a month against HP's £559, because PCP only repays the car's depreciation. But PCP charges interest on the full amount borrowed for the whole term, including the £10,000 balloon you haven't paid off. Keep the car and PCP's total hits £30,280 versus £29,325 on HP — £955 more, despite the identical car.
Can I settle car finance early?
Yes. Personal loans and HP/PCP agreements can be settled early, with interest rebated under the Consumer Credit Act (lenders may charge up to around two months' interest). HP and PCP also carry a voluntary termination right: once you've paid half the total amount payable, you can hand the car back and walk away, subject to fair wear and tear.
What happens at the end of a PCP agreement?
You choose one of three exits: pay the £10,000 balloon (the guaranteed minimum future value) and keep the car; hand the car back with nothing more to pay if it's within mileage and condition limits; or trade it in, using any value above the balloon as the deposit on the next deal. Most PCP customers roll into a new agreement — which is exactly what the product is designed to encourage.
Should I take dealer finance or a bank loan?
Get a personal loan quote from your bank before you visit the showroom, then make the dealer beat it on total amount payable — not monthly payment. Best-buy personal loans (around 5.6% in 2026) typically undercut PCP and HP rates by 2–3%. Dealers earn commission on finance they arrange and must tell you how they're paid if you ask — the FCA requires commission disclosure.
