Is car finance worth it? How to pay for a car, judged on the arithmetic

The four routes, and what each actually costs

1. Cash costs the least and carries the whole depreciation. Buying outright has no interest and no agreement, so it is the cheapest way to own a car and the only one where nobody can repossess it. What it does not avoid is depreciation, which is the largest cost of running a car whether you financed it or not. The real comparison is between the interest you would pay and the return you would otherwise get on the money, plus the value of keeping it accessible.
2. A personal loan buys the car outright with borrowed money. An unsecured personal loan makes you the owner from the first day, which means you can sell the car whenever you like and the lender has no claim on it. That flexibility is the main advantage over hire purchase, and it matters if your circumstances may change. The trade off is that unsecured lending is usually priced higher than secured motor finance for the same borrower, and the rate advertised is not necessarily the rate offered.
3. Hire purchase is secured on the car and ends in ownership. Hire purchase spreads the whole price with interest and transfers ownership at the final payment. Because the debt is secured on the vehicle, rates are typically lower than an unsecured loan for the same file. The protections are real: s.90 blocks repossession without a court order once a third of the total price is paid, and s.99 lets you hand the car back once you have paid half. You cannot sell the car until it is settled.
4. PCP defers depreciation risk to the lender, at a price. PCP repays only part of the price and defers the rest to a guaranteed minimum future value the lender is bound by. The monthly payment is lower and you are protected if the car falls below that value. The costs are that interest is charged on the deferred amount too, the mileage limit is a real price, and at the end you own nothing unless you fund the balloon. It suits a buyer who changes cars often and is expensive for one who keeps them.

Is pcp a good idea? It depends on one question you can answer now

The question is whether you intend to keep the car past the end of the term. If you do, the deferred final payment costs you interest on money you were always going to pay, and hire purchase over the same period is usually cheaper in total. If you do not, the lower payment buys you the option of walking away at a value the lender guaranteed, and that option has real worth on a car whose used value is hard to predict.

So it is a good idea for a driver who changes car every few years and wants the residual risk on somebody else's books, and a poor one for a driver who keeps cars for a decade. Nothing about the rate decides it: the structure does.

The dangers of pcp finance are the mileage, the condition and the equity

Three things turn a comfortable PCP into an expensive one. Exceeding the contracted mileage is charged per mile at the end and is the commonest surprise. Returning the car outside fair wear and tear produces a bill set against an inspection standard most people have never read. And negative equity, where the car is worth less than the settlement figure, removes the part exchange that the whole plan assumed.

None of the three is hidden: the mileage, the excess rate and the condition standard are all in the agreement, and equity can be measured at any point from a trade valuation and a settlement figure. They become dangers when nobody looks at them until the last month.

Common questions

Is it better to buy a car outright or finance it?

Outright is cheapest in interest and gives you immediate ownership. Finance is worth it where the interest is less than what the money earns elsewhere, or where the alternative is a much older car.

Hire purchase or personal loan: which is better?

A loan makes you the owner immediately so you can sell the car at will. Hire purchase is secured on the vehicle and so is usually cheaper for the same borrower. The right answer depends on whether flexibility or rate matters more.

What are the disadvantages of PCP?

Interest is charged on the deferred balloon, the mileage limit is priced, condition is assessed at the end, and you own nothing unless you pay the balloon.

What are the advantages of hire purchase?

It ends in ownership, it is secured so usually cheaper than unsecured borrowing, and it carries the s.90 protected goods rule and the s.99 voluntary termination right.

Can I get out of any of them early?

Section 94 gives the right to settle a regulated agreement early at any time. Section 99 adds voluntary termination once half the total amount payable has been paid.
