New Car Finance vs Used Car Finance: Which Is Cheaper?
Finance a new car or a used one — compared on rate, depreciation and total cost.
Used car finance usually has a lower total cost because the car is cheaper, but new car finance often carries a lower rate and sometimes a 0% deal.
Used car finance usually costs less overall because the car is cheaper, while new car finance often has a lower interest rate and sometimes 0% offers. Less to borrow on used; a better rate on new.
New cars depreciate fastest in the first years, so a nearly-new used car can give you most of the car for far less finance — and the lower rate on new is rarely enough to close the price gap.
New vs used car finance at a glance
Used finance means borrowing less; new finance often means a lower rate. Depreciation hits new cars hardest in the early years.
A new car loses value quickest in its first three years — often 30–50% of its price — so you finance a price that drops fast. A used car has already taken that hit, so you borrow less, though the rate is often a touch higher to offset the lender's risk on an older car. The two forces pull in opposite directions, and the cheaper price usually wins.
This is the central insight of the new-vs-used comparison: the rate advantage on new finance is real but small (a few percentage points), while the price advantage on used is large (often thousands of pounds). A lower rate on a much bigger balance usually loses to a slightly higher rate on a much smaller balance — and the depreciation makes the gap worse, because the new-car buyer is paying interest on a price the car will never be worth again.
| New car finance | Used car finance | |
|---|---|---|
| Amount borrowed | Higher (full new price) | Lower (cheaper car) |
| Typical rate | Often lower, sometimes 0% | Usually a bit higher |
| Depreciation profile | Fastest in year 1–3 | Already taken the hit |
| Total cost | Higher (price + rate) | Usually lower |
| 0% deals? | Common via manufacturers | Rare outside approved-used |
| Warranty | Full manufacturer warranty | Shorter or expired |
| Best for | Latest model, 0% deals | Lowest total outlay |
Worked example: new vs used finance
A £20,000 new car on finance can cost about £23,695 in total on HP; a £14,000 used version of the same model borrows far less, even at a slightly higher rate.
The cheaper car usually wins on total cost; the lower rate (or a 0% deal) is what makes new finance competitive, and even a 0% offer rarely closes the price gap. Compare both on the used car finance calculator and the new car finance calculator, then verify the totals on the APR & true-cost calculator.
Worked example
Who each option suits
Finance used for the lowest total outlay; finance new for the latest model, a lower rate or a 0% deal.
- Used car finance if: you want the lowest total cost, want to dodge the steepest depreciation, and don't need the very latest model.
- New car finance if: you want the newest car with a full warranty, can get a genuine 0% or low rate, and plan to keep it long enough to offset the depreciation.
- A nearly-new car (1–3 years old) often blends most of both — a modern car at a lower price, gentler depreciation, and sometimes still under the manufacturer warranty.
Pros and cons: new vs used finance
New finance wins on rate, warranty and 0% deals; used finance wins on price, depreciation and total cost.
| Pros | Cons | |
|---|---|---|
| New car finance | Lower rate, possible 0%, full warranty, latest tech | Higher price, steep depreciation, higher total cost |
| Used car finance | Lower price, past the steepest depreciation, lower total cost | Higher rate, shorter or no warranty, needs more checks |
The sweet spot: nearly-new (1–3 years old)
A nearly-new car often gives you the best of both routes — most of the modern car, a much lower price, gentler depreciation, and often a manufacturer warranty still in force.
The first owner of a new car takes the steepest depreciation hit — often 30–40% in the first year alone, and 50%+ by year three. A nearly-new buyer steps in after that cliff, paying substantially less for what is still a modern car with current technology, low mileage, and frequently the balance of the manufacturer warranty (typically 3 years, sometimes up to 7 on some brands).
On finance, a nearly-new car borrows less than the new equivalent, so the total is lower even at a slightly higher rate. The depreciation curve from year 3 onwards is much gentler, which means if you finance it on PCP the balloon is more predictable and the negative-equity risk is smaller. For most buyers, the nearly-new route is where the value sits — the new-car premium buys you the latest registration plate and the first-owner feeling, but very little that materially changes the car.
The exception is when a genuine 0% deal narrows the gap. A 0% offer on the new car removes the interest and can make the new route competitive with nearly-new on total cost — though it usually still doesn't beat it outright, because the price gap is larger than the interest saved. Run both on the new car finance calculator and used car finance calculator to see how close they land for your specific car.
Warranty, repairs and reliability
A new car comes with a full warranty and zero repair history; a used car carries more repair risk and may need checking. The warranty value is a real part of the new-car premium.
The new-car warranty is worth money. A typical 3-year manufacturer warranty covers most major failures at no cost to you, which means the first three years of new-car ownership carry very little repair risk. That peace of mind is part of what you're paying for with the higher new-car price.
A used car outside warranty carries the repair risk directly. An older car is statistically more likely to need work — clutch, timing belt, suspension, electrical — and those bills can run to thousands. Approved-used schemes from manufacturers soften this with at least 12 months of warranty, which is one reason they're popular, but independent used purchases carry whatever warranty the seller offers, often short or none.
Build the expected repair cost into the comparison rather than treating it as a separate worry. Add a realistic annual repair budget to the used-car side on the total cost of ownership calculator, and treat the new-car warranty as a built-in saving on the new side. The picture that emerges is more honest than a pure finance comparison — and for buyers who'd struggle to absorb a £2,000 repair bill, the new-car warranty can be worth the premium on its own.
The three-quote rule and how to negotiate either route
Whichever car you choose, get at least three written finance quotes — a dealer quote, a broker quote, and a bank or online lender — because the APR spread on the same car is often 2–4 percentage points, which is hundreds of pounds a year.
On the new-car side, the dealer's manufacturer-subsidised rate isn't always the cheapest, even with a 0% headline; some 0% deals require a large deposit and a short term that pushes the monthly up, while a low-rate subsidised deal over a longer term can have a lower total. Ask for the total amount payable on each option, and compare a 0% offer against a deposit-contribution deal where the discount comes off the price rather than the rate.
On the used-car side, dealer finance is convenient but rarely the cheapest source — a broker or your own bank will often undercut the forecourt rate, especially on older cars where dealers price in a wider margin. Get a quote in principle from a broker before you visit the dealer, so you have a benchmark. Dealers sometimes match a cheaper outside rate to keep the finance commission, which is a genuine win for you.
On both routes, settle early and you're entitled to a rebate of interest under the Consumer Credit Act 1974 for HP and PCP — see how to settle car finance early. That means a slightly higher rate isn't a trap if you expect to clear the finance early (a bonus, an inheritance, selling another car), because you won't pay the full term's interest. Run the settlement maths before you assume a lower headline rate is automatically the better deal.
VAT, deposits and how the car's price is built
On a new car the sticker price includes VAT the dealer can sometimes discount; on a used car from a dealer the VAT is already accounted for, which changes how you negotiate the deposit and the discount.
New car prices include 20% VAT, and dealers have some flexibility on that margin when they quote finance — a deposit contribution or a free servicing pack is often easier to win than a cash discount, because it preserves the headline price. On a used car sold by a dealer under the VAT margin scheme (common for older stock), the dealer pays VAT only on their profit, not the full price, which is why used-car discounts are usually smaller and harder to negotiate than new-car ones.
The deposit matters more on used finance, because borrowing less at a slightly higher rate can still beat borrowing more at a lower rate. Putting £2,000 rather than £1,000 down on a £14,000 used car can drop the total interest noticeably even at 11% APR, because the rate works on a smaller balance for the whole term. Run different deposit levels on the used car finance calculator to see how the split moves the total.
If you part-exchange, the trade-in value comes off the amount you're borrowing, which has the same effect as a bigger deposit — but only the net figure after settling any existing finance counts. Check your current car's settlement figure first on the settlement route, because negative equity on a part-exchange can quietly inflate the new loan and undo the used-car price advantage.
Work out your own numbers
Compare the amount borrowed and the rate side by side, factor in depreciation and warranty value, and check whether a 0% deal closes the gap.
Run the figures on the used car finance calculator and the new car finance calculator, then check each deal's true APR and interest. Add depreciation and expected repairs on the total cost of ownership calculator, and test a few deposit levels and part-exchange figures to see how the balance shifts. See it all on the car finance calculator. The comparison that matters is total cost to own, including the depreciation you'll eat on the new car and the repair risk you absorb on the used — and on that measure, used or nearly-new usually wins unless a 0% deal is in play.
