0% Finance vs a Cash Discount: Which Is Cheaper?
Take the interest-free deal or the discount for paying cash — which really costs less.
Work out both in pounds: a 0% deal saves you the interest, but a big cash discount can beat it — compare the total you actually pay, not the headline.
A 0% finance deal costs nothing in interest, but a cash discount can be worth more — so compare the total you actually pay either way. One waives the interest; the other cuts the price upfront.
Dealers often make you choose: take 0% finance at the full price, or pay cash for a discount. The cheaper route depends on the size of that discount.
0% finance vs a cash discount at a glance
0% finance saves the interest; a cash discount cuts the price now. The winner is whichever leaves you paying less in total.
On a true 0% deal you pay only the list price, spread over time, with your savings intact. With a cash discount you pay less, but in one lump from your own money. The bigger the discount, the more likely cash wins.
| 0% finance | Cash discount | |
|---|---|---|
| Interest paid | None | None (you pay cash) |
| Price paid | Full list price | Discounted price |
| Keep your savings? | Yes | No |
| What to compare | Total at full price | Discounted total |
| Best for | Keeping cash free at 0% | A big enough discount |
Worked example: 0% finance vs a cash discount
On a £20,000 car, 0% finance means paying £20,000 over the term; a £1,500 cash discount means paying £18,500 now — so the discount wins on price.
If your savings earn very little, the cash discount usually wins. If keeping that money available matters, 0% can be worth the higher price. Check that the 0% is genuine — sometimes it's only on the list price after the discount is removed. Compare totals on the APR and true-cost calculator.
Worked example
Who each option suits
Take the cash discount when it's bigger than the value of keeping your money; take 0% when keeping your savings free is worth more.
- Cash discount if: the saving is substantial, your savings earn little interest, and you can comfortably part with the money.
- 0% finance if: it's a genuine interest-free deal, you'd rather keep your cash for emergencies, or your savings earn more than you'd save by discounting.
- Beware deals where you can't have both — work out the true total each way before you choose.
Work out your own numbers
Put the discounted cash price next to the full-price 0% total — the lower number wins.
Use the APR and true-cost calculator to confirm a 0% deal is genuine, and read 0% car finance deals to spot the catches. For the wider call, see finance vs paying cash.
