0% Car Finance Deals: Are They Worth It?
How interest-free finance really works, where to find it, and the catch behind the headline.
0% car finance is genuinely free of interest — you pay back exactly the cash price, spread over the term. But it's rarely free of every cost: 0% deals usually skip the cash discount you'd get for paying outright, so the true saving can be smaller than it looks.
The honest test is simple. Add up everything you pay on the 0% deal, then compare it with the cash price minus any discount you'd be offered. The cheaper total wins — not the one with 0% on the sticker.
Is 0% car finance really free?
Yes — on a true 0% APR deal you pay no interest, so the total you repay equals the cash price. Borrow £20,000 over 48 months at 0% and you pay £20,000, in 48 payments of about £417.
Compare that with the same car on a typical 9.9% APR deal, where you'd repay around £23,700 — roughly £3,700 in interest. On paper, 0% saves you that £3,700. The catch is what you give up to get it.
Check any quote against the APR & true-cost calculator — it turns a monthly figure back into an APR and shows the total interest, so a '0%' claim is easy to verify.
How do 0% car finance deals work?
0% deals are usually manufacturer offers, subsidised by the carmaker to shift specific models. The dealer still gets paid; the manufacturer covers the interest instead of you.
Because the carmaker is footing the interest bill, the deal is built to suit them, not you. That's why the terms are tighter than a standard HP or PCP agreement.
- They're tied to certain models, trims or registration plates — often slower-selling or end-of-range stock.
- They usually need a larger deposit (often 20–40%) and a shorter term (typically 24–36 months), which pushes the monthly up.
- They're offered to buyers with a strong credit file — a 0% headline doesn't mean everyone qualifies for it.
Where to find 0% car finance
0% finance comes almost entirely from manufacturer finance arms, not high-street lenders or brokers. You'll find it on new cars during a sales push, rarely on used.
Look at carmaker websites, franchised dealer offers, and end-of-quarter or plate-change periods (March and September) when targets are tightest. Independent dealers and personal loans almost never run at 0%. Read more in manufacturer car finance.
0% finance vs a cash discount
0% finance often costs more overall than taking a cash discount, because you forfeit the discount to get the 0%. Work out both totals before you sign.
In this example the cash discount wins by £2,000, even though the finance is interest-free. If you don't have the cash, a low-rate loan plus the discount can still beat 0% — see interest-free car finance for how to run that comparison.
| 0% finance | Pay cash with discount | |
|---|---|---|
| Headline price | £20,000 | £20,000 |
| Discount offered | £0 | £2,000 |
| Interest paid | £0 | £0 |
| Total you hand over | £20,000 | £18,000 |
Check the true cost before you sign
The number that decides it is the total amount payable, not the 0% on the poster. Compare every deal on what you actually hand over.
Put your figures into the APR & true-cost calculator to see the total and any hidden interest, then run the same car on the main car finance calculator to compare 0% against a discounted cash buy or a standard finance deal side by side.
