Car Finance vs Paying Cash: Which Is Cheaper?
Borrow or pay outright — the true cost of financing a car versus paying cash.
Paying cash is cheaper because you pay no interest, but financing can be worth it if you'd rather keep your savings or land a genuine 0% deal.
Paying cash is cheaper overall because you pay no interest, while financing spreads the cost but adds interest. Cash saves you the interest; finance keeps your savings free and may unlock a 0% deal.
The maths usually favours cash. The exception is a true 0% offer, or when keeping a cash cushion is worth more to you than the interest.
Finance vs cash at a glance
Cash avoids all interest and you own the car instantly; finance keeps your savings but adds the cost of borrowing. The gap is the total interest.
Finance lets you keep money in the bank for emergencies, but you pay for the privilege through interest. Cash costs you nothing extra and you own the car from the moment you pay — but it empties your savings.
| Car finance | Paying cash | |
|---|---|---|
| Upfront cost | Low (deposit only) | Full price now |
| Total cost | Price + interest | Just the price |
| Own the car? | Depends on the product | Instantly, outright |
| Keep your savings? | Yes | No |
| Best for | Keeping cash free, 0% deals | Lowest total cost |
Worked example: financing vs paying cash
Buy a £20,000 car on HP and you pay about £3,695 in interest over the term; pay cash and that £3,695 stays in your pocket.
If your savings earn less interest than the finance charges, cash wins outright. If a dealer offers a genuine 0% deal, financing can match cash while keeping your money free. Check any deal on the APR and true-cost calculator, and compare a 0% offer against a cash discount.
Worked example
Who each option suits
Pay cash for the lowest total; finance to keep your savings or to use a true 0% deal.
- Pay cash if: you have the money spare, your savings earn less than the finance rate, and you want the lowest total cost.
- Finance if: emptying your savings would leave you exposed, you can get 0% or a low rate, or you'd rather keep cash for emergencies.
- Watch for cash discounts the dealer drops if you finance — sometimes paying cash and skipping the deal still wins.
Work out your own numbers
Put the total interest next to your lost savings interest — whichever is larger points to the answer.
Use the APR and true-cost calculator to see the interest on any deal, then compare products on the car finance calculator. If you're weighing a discount, see 0% finance vs a cash discount.
