Negative equity means the car is worth less than you owe. You can settle, sell with the shortfall covered, or wait until you're back in positive equity.

How we work this out
Equity = the car's market or part-exchange value − your settlement figure. A negative result is negative equity (a shortfall you must cover); a positive result is equity you could use towards a new car.
Use a realistic trade or part-exchange value, not the higher forecourt price — dealers pay the trade price when you part-exchange.
Full method: how we calculate.
Negative equity is when your car is worth less than the amount you still owe on it. This calculator works out your position from the car's current value and your settlement figure, and shows the shortfall if there is one — or the equity if you're in the black.
Negative equity matters most when you want to sell, part-exchange, or end a finance deal early. If the car is worth less than the settlement figure, the sale won't cover what you owe and you'll need to find the difference in cash. Knowing the number before you act stops a nasty surprise at the dealership.
What is negative equity on car finance?
Negative equity means you owe more on your car finance than the car is worth. If you sold the car today, the price wouldn't cover the settlement figure, and you'd need to cover the gap.
It's common in the early years of a PCP or HP deal, when the car depreciates fastest while your finance balance falls more slowly. Cars typically lose 15–35% of their value in the first year and continue to depreciate for several years, but finance balances reduce steadily — so there's a window where the two lines cross and you're 'underwater'.
Negative equity isn't a default, a fine, or a credit-file problem. It only bites if you try to exit the deal before the balance has caught up with the value — by selling, part-exchanging, or settling early. If you simply keep paying to the end of the term, negative equity usually resolves itself.
Am I in negative equity?
You're in negative equity if your settlement figure is higher than the car's current value. Enter both above to see the shortfall — or the equity if the car is worth more.
To check your position you need two numbers: your settlement figure (from your lender) and the car's current trade or part-exchange value (from a valuation tool). Don't use the forecourt retail price — a dealer part-exchanging your car pays the trade price, which is lower.
Worked example
Why it happens — PCP, HP and depreciation
Negative equity happens because cars lose value fastest early on, while your finance balance falls more slowly. A small deposit and a long term make it more likely; a big deposit and a short term make it less so.
On PCP the effect is amplified, because the monthly payments are deliberately kept low (they only cover depreciation plus interest, with the balloon deferred). That means the balance stays high for longer relative to the car's value. On HP you're paying off the full price, so the balance falls faster and negative equity tends to clear sooner.
Depreciation is steepest in year one and gradually flattens. So negative equity is usually worst in the first 12–24 months and improves as you go — provided you're not adding to the debt by rolling in fees or another car's negative equity.
| Year | Car value | Finance balance | Position |
|---|---|---|---|
| Year 1 | £17,000 | £19,500 | £2,500 negative |
| Year 2 | £15,000 | £16,800 | £1,800 negative |
| Year 3 | £13,500 | £13,800 | ≈ break-even |
| Year 4 (end) | £12,000 | £10,000 (balloon) | £2,000 equity |
How to get out of negative equity
You can wait it out, settle the shortfall, or sell and cover the difference — though rolling it into a new deal adds to your next debt. Waiting is usually the cheapest option if you can.
- Wait: keep paying until the balance falls below the car's value. Negative equity usually clears itself as the balance reduces and depreciation flattens. This is almost always the cheapest option.
- Overpay to close the gap: put extra towards the balance to reach positive equity faster — see the overpayment calculator.
- Settle the shortfall: pay the gap in cash to clear the finance — work out the figure with the settlement calculator.
- Sell or part-exchange and cover the difference from savings — see selling on finance.
- Avoid rolling the negative equity into a new agreement unless you've weighed the total cost carefully — it increases your new balance and your new interest.
Beware rolling it over
Voluntary termination and negative equity
Voluntary termination (VT) sidesteps negative equity: once you've paid 50% of the total amount payable, you can hand the car back and owe nothing more, even if it's worth less than the balance.
VT is a powerful escape hatch precisely because it ignores the car's current value. Whether you're in £1 or £5,000 of negative equity, the right is the same: pay 50% of the total amount payable (deposit + all monthly payments + balloon on PCP) and return the car. See voluntary termination for the conditions — mainly reasonable condition and mileage.
Your VT right
Depreciation curves and the negative-equity window
Negative equity is a window, not a permanent state — it opens the day you drive off the forecourt (the car's first big value drop) and usually closes partway through the term as the balance catches up.
A new car typically loses 15–35% of its value in the first year and a similar chunk again by year three, while the finance balance falls in a straight line (HP) or a shallow curve (PCP, where the balloon keeps the balance high). Where the falling value line crosses the falling balance line, negative equity turns into equity. On the illustrative PCP in the table above, that crossover lands around year three.
Two things widen the window: a small deposit (the balance starts closer to the price, so it's higher for longer) and a long term (the balance falls more slowly). A bigger deposit and a shorter term narrow it. Depreciation also varies by car — desirable models hold value and may never go negative; high-volume models can sink faster than the balance for years.
Read the curve, not the snapshot
Part-exchange and roll-over: the maths
When you part-exchange a car in negative equity, the shortfall doesn't vanish — the dealer adds it to your next finance balance, and you pay interest on it inside the new loan. That's why roll-over is the most expensive way out.
Say your car is worth £8,500, the settlement is £10,000, and you're buying a £20,000 car. The dealer pays off your £10,000 finance, but only £8,500 of that came from the part-exchange — so £1,500 of shortfall is folded into the new deal. Your new finance is now £21,500 (£20,000 + £1,500) instead of £20,000, and you pay interest on the rolled-in shortfall for the whole new term. On a 48-month deal at 9.9% APR, that's roughly £390 extra in interest on top of the £1,500 itself.
Roll-over also puts you straight back into negative equity on the new car, because you're starting with a balance above the new car's price. The cleaner route is to settle the shortfall in cash, wait for the curve to recover, or use voluntary termination at the 50% mark if you just want out.
Common negative-equity mistakes
Negative equity at the end of a PCP
At the end of a PCP, the balloon is fixed — so if the car is worth less than the balloon, you simply hand it back and the lender takes the loss. Negative equity is the lender's problem, not yours, on a regulated PCP.
That's the 'guaranteed' in GMFV working in your favour. If the car is worth more than the balloon, you have equity to put towards a new deal or to keep the car for less than expected. If it's worth less, you walk away. The only time end-of-PCP negative equity costs you is if you choose to buy the car for more than it's worth — which you're never obliged to do.
