Is 0% Car Finance Worth It? How to Tell

Is 0% car finance actually worth it?

Sometimes. You can work out which.

0% means you pay back what you borrowed and no interest on top. That part is real. What it doesn't tell you is the price of the car.

A rate gets applied to a price. The rate can be zero and the price can still be high. So the question isn't whether 0% is a good rate, because it plainly is. It's whether this deal, at this price, beats the alternative you could get.

One comparison settles it. You can do it on a phone.

The only comparison that settles it

Put the two routes side by side as total amounts of money.

1. The 0% deal. Add the deposit to every monthly payment, plus any final payment and any fees. That's what the car costs you.
2. The alternative. Take the best cash price you can get for the same car. Add whatever it would cost you to borrow that sum, if you'd need to.

Then compare the two numbers. Not the rates. The numbers.

A regulated credit agreement has to set out what you'll pay in total, so you shouldn't have to build the figure yourself. Ask for it in writing before you decide.

Why this matters: the offer and the discount can come out of the same budget. The FCA's own market analysis says 0% APR deals are subsidised by manufacturers through captive lenders or white-label products, to promote particular vehicles. In promotional periods, it says, many of them "prioritise discounting financing costs rather than the RRP of the vehicle" (FCA, Technical Annex 2, October 2025).

Which lever they've pulled on your car is one question away. That's the next chapter.

What to ask before you sign

Four questions. Ask them in this order and write the answers down.

• What's the cash price of this car if I don't take the finance?
• What's the cash price if I do?
• What deposit does the 0% deal need, and over how many months?
• What fees are there, and are they inside or outside the total?

If the two cash prices are the same, the finance is genuinely free money and I'd probably take it. If the cash price is higher with the 0% deal, you now know exactly what the interest-free borrowing is costing you. Either way you've turned a sales pitch into a number.

The deposit and the term are set by the offer, not by you, and they needn't match a standard agreement. Neither is a catch on its own. Both change whether you can actually afford it, so get the numbers rather than assuming. Eligibility is worth asking about early, too: the FCA describes new-car finance offers as catering "almost exclusively to prime customers" (FCA, Technical Annex 2).

What finance gives you that paying cash doesn't

This is the part most comparisons leave out, and it can decide the question on its own.

When you buy a car on hire purchase or PCP, the finance company buys the car and supplies it to you. Legally they're the supplier, not just the lender. The Consumer Rights Act 2015 counts hire purchase as a contract to supply goods (s.3).

So if the car turns out to be faulty, your claim is against them. They're a company that's regulated and still exists.

Compare that with handing cash to a private seller who stops answering their phone.

Section 75 is a different route, and not this one

Section 75 of the Consumer Credit Act 1974 makes a lender jointly liable with the supplier for misrepresentation or breach of contract. It gets cited a lot in car-buying advice, and it's worth being clear about where it lands.

It doesn't apply to hire purchase or PCP. Section 75 reaches only the agreements in section 12(b) or (c) of the Act (s.75). Those are the ones where the lender and the supplier are two different parties. On HP and PCP the lender is the supplier, which puts the deal in section 12(a) instead.

You lose little by that. The claim described above runs straight at the finance company and is the stronger one anyway. Where section 75 does earn its keep is a deposit paid by credit card, because the card is a separate agreement with a third party. It doesn't apply where the cash price of the item is £100 or less, or more than £30,000, and that upper limit rules out a good many new cars.

For how hire purchase and PCP differ from each other, and what you can walk away from, read our guide to HP vs PCP car finance. There is more of this in our car ownership advice.

Buying used from a dealer rather than new? Finance already owing on the car is a different problem from the finance you're being offered, and our guide to outstanding finance covers it.

Where motor finance regulation stands, as at September 2026

Motor finance has been under regulatory scrutiny for years, and it's worth knowing where that has got to.

The FCA banned discretionary commission arrangements with effect from 28 January 2021, having announced the ban the previous July. Those let a broker adjust your interest rate and earn more commission for doing it (FCA).

The FCA then confirmed a consumer redress scheme in March 2026. It covers motor finance agreements taken out between 6 April 2007 and 1 November 2024 where the lender paid the broker commission. Lenders had until 30 June 2026 to get ready for agreements from April 2014 on, and until 31 August 2026 for older ones.

Then, on 2 July 2026, parts of the scheme were suspended by an order of the Upper Tribunal while legal challenges are heard. The case is listed for December 2026 or February 2027 (FCA).

Lenders are still identifying complaints. They don't have to work out or pay compensation while the legal process runs. If the scheme is upheld without appeal, the FCA expects payments to start in 2027 (FCA).

Two things follow for you. A 0% deal is not what any of this is about. The FCA's final rules except zero-APR agreements from counting as a "relevant arrangement", so they can't give rise to a scheme case at all (FCA, PS26/3). And if you had car finance between 2007 and 2024, watch how the case lands rather than assuming an outcome either way.

When 0% is genuinely the better deal

It's the better deal when the cash price doesn't move. Same car, same price, no interest: you keep your money for longer and the agreement brings protections that cash doesn't.

It's worth taking seriously when the deposit and the term suit you anyway, and when you were going to borrow the money regardless. Interest-free borrowing beats paying interest, every time, on the same price.

It's the worse deal when the price goes up to pay for it, when the deposit stretches you, or when it pushes you into a car you didn't want. None of that shows up in the headline rate. All of it shows up in the total.

Finance isn't automatically the right answer either. It affects your credit file and it commits you for years. The point of this page isn't to talk you into it. It's to make sure you're comparing prices, not rates.
