Quick Answer
Paying off car finance early means asking your lender for a settlement figure — today's outstanding balance plus up to 58 days' interest — in exchange for a rebate of the future interest you would have paid. For example, £250 a month with 24 payments left at 10% APR settles at about £5,524 instead of £6,000, saving roughly £476. This calculator works out that settlement figure and saving, or checks the 50% "voluntary termination" point where you can hand the car back and owe nothing more.
How the Car Finance Early Payoff Calculator Works
There are two ways to end UK car finance early, and this calculator covers both. Early settlement means paying the balance off now: you ask for a settlement figure, get a rebate of future interest under the Consumer Credit Act, and keep the car. Voluntary termination means handing the car back once you have paid half the total — the “50% rule”. Both are legal rights on regulated HP and PCP agreements, and neither carries an early-repayment penalty beyond the statutory interest.
Interest saved: what you’d pay to the end (monthly × payments left) − the settlement figure.
50% rule (voluntary termination): you can hand the car back once you have paid 50% of the total amount payable.
The settlement balance is the present value of your remaining payments at the agreement’s rate — so it is always less than simply multiplying the monthly payment by the months left. Under the Consumer Credit (Early Settlement) Regulations 2004 the lender rebates the future interest, though on agreements over 12 months they may keep up to 58 days’ interest. The result is the exact figure your lender quotes (valid for about 28 days).
How to Use the Early Settlement Calculator
-
Pick a mode
Use Settle & pay off now to price paying the finance off, or Hand it back (50% rule) to check voluntary termination.
-
Settle mode: enter your payment, payments left and APR
Type your monthly payment, how many payments remain (switch to years if easier) and the APR from your agreement. The tool shows the settlement figure and what you save.
-
Hand-back mode: enter the total amount payable and what you’ve paid
Put in the “total amount payable” from your agreement and everything you’ve paid so far, including the deposit. Add your monthly payment to see how many payments reach the 50% point.
-
Read the result and confirm with your lender
You get the settlement figure and saving, or the halfway figure and whether you’ve reached it. Always request the official settlement figure before paying.
Worked Examples: Settlement & the 50% Rule
Every figure below is exactly what the calculator prints — enter the same inputs to check.
Early settlement figure & saving
| Monthly | Payments left | APR | Settlement | You save |
|---|---|---|---|---|
| £250 | 24 | 10% | £5,523.82 | £476.18 |
| £300 | 36 | 12.9% | £9,181.42 | £1,618.58 |
| £200 | 18 | 8% | £3,430.64 | £169.36 |
| £250 | 12 | 0% | £3,000.00 | £0.00 |
At 0% APR there is no future interest to rebate, so settling early saves nothing — you simply pay the balance.
Voluntary termination — the 50% point
| Total amount payable | Paid so far | 50% point | Result |
|---|---|---|---|
| £15,000 | £6,000 (40%) | £7,500 | £1,500 to go — about 6 more payments |
| £20,000 | £11,000 (55%) | £10,000 | Reached — hand back, £1,000 over halfway |
| £12,000 | £6,000 (50%) | £6,000 | Reached exactly — you can terminate |
The 50% Rule (Voluntary Termination) Explained
Voluntary termination is a protection under section 99 of the Consumer Credit Act 1974. Once you have paid 50% of the total amount payable, you can end the agreement, hand the car back and owe nothing further — as long as the car is in reasonable condition and within any mileage limit. If you have paid less than 50%, you can still terminate but must pay the difference up to the halfway point. An insurance write-off ends the agreement a different way — the car insurance write-off calculator checks the repair-to-value ratio and the payout after excess.
| Situation | What you pay to hand it back |
|---|---|
| Paid less than 50% | The difference up to the 50% point (plus any damage/excess mileage) |
| Paid exactly or over 50% | Nothing more (subject to condition and mileage) — but you don’t get the extra back |
