Car Written Off: How Much Will I Get?
The short answer: you should get the pre-accident market value of your car — what it would have cost you to buy the same car, in the same condition, from a dealer the day before it was damaged. Not what a trader would pay for it. Not the cheapest example on the internet. What replacing yours would actually cost.
Free to check, no obligation — and you can challenge your insurer yourself for free, with the Financial Ombudsman free after that. This takes you to Allegiant Finance Services, our car write-off partner — Claims Bible is paid for accepted introductions.
That's the rule. The practice is less reliable: the FCA reviewed how insurers value written-off cars and found firms making offers below the available guide prices, applying deductions that could produce unfair outcomes, and making initial offers that were not their best offers. So the number in your settlement letter is a starting position, not a verdict — and it's worth understanding how it was produced before you accept it.
How insurers actually calculate the payout
When your insurer declares the car a total loss, its valuation should be built from your exact car: make, model and trim, engine, year, mileage, condition, service history, MOT status and factory options. In practice insurers lean on the motor trade guides — the industry valuation databases that price cars by spec and mileage — plus advertised prices for comparable cars.
Where it goes wrong is which numbers get used. An offer built on trade or auction prices (what a dealer pays, not what you'd pay), matched against a lower specification than your car, or anchored to a handful of outlier cheap adverts will land below a fair replacement cost — sometimes by hundreds of pounds, sometimes by thousands on newer or higher-spec cars.
What gets deducted from the payout
Before the money reaches you, expect some or all of these to come off:
- Your policy excess — always deducted from a claim on your own policy.
- The salvage value, if you keep the car — buying back a Cat S or Cat N car means the insurer deducts what the salvage was worth.
- Outstanding premium — the FCA found around half of firms deduct the remaining year's instalments from the settlement rather than letting you keep paying monthly. Check your final statement for this.
- Prior write-off markers — some insurers deduct heavily (the FCA saw 20%) where the car was previously a total loss. The regulator's view is that the individual circumstances and category should be considered, not a flat cut.
What should not be deducted is value your car genuinely had: a full service history, a fresh MOT, recent big-ticket maintenance, or factory options the valuation ignored.
What a fair offer looks like
A fair settlement lets you walk into a dealer and buy the car you lost. Practical test: search the classifieds for your exact model, year, trim and mileage, and see what those cars are actually advertised at today. If the insurer's offer wouldn't buy one, the offer is light. The Financial Ombudsman Service takes the same approach — it cross-checks offers against the motor trade guides, and it regularly finds for customers where the offer sat below them.
Check your settlement gap
You now have everything the sums need: the insurer's offer, and what your advert research says replacing the car actually costs. Put both in — the checker shows the shortfall on your figures, what you'd keep after our partner's fee, and what you'd keep challenging it yourself for free. We don't estimate your car's value; the two numbers are yours.
Write-off settlement gap checker
Your figures, honest arithmetic — we don’t guess your car’s value.
You do not need a claims company. You can challenge the valuation with your insurer yourself for free and, if you are not satisfied with their final response, escalate free to the Financial Ombudsman Service within six months.
You said the remaining premium was (or may have been) deducted. The FCA’s review of total loss claims found around half of firms deducting the rest of the year’s instalments from settlements — check your final statement, and query the deduction if the treatment seems unfair.
This is arithmetic on the two figures you entered, not a valuation — we don’t estimate what your car was worth, because only the motor trade guides and real like-for-like adverts can do that. Whether a challenge succeeds depends on the evidence, and no outcome is guaranteed.
Why this checker doesn't guess your car's value
Because no formula can. A car's real value lives in the motor trade guides the insurers and the Ombudsman use, and in what like-for-like cars are actually advertised at this week — not in a depreciation curve applied to whatever you paid. A tool that types your car's age into a formula and prints a "valuation" isn't telling you what your car was worth; it's giving you a number to anchor on, and if that number is wrong in the insurer's favour, it can talk you into accepting a low settlement.
So ours works the other way round. You bring the two numbers that are actually knowable — the insurer's offer, and the replacement cost from your own advert research — and the checker does honest arithmetic on them. The side effect is the point: the adverts behind your replacement figure are exactly the evidence a valuation challenge is built on, so by using the checker properly you've already done Step 2 of challenging the offer.
If your car was on finance
The payout goes first towards settling what you owe the finance company on PCP or HP. If the valuation was low, that shortfall is your problem — which makes an undervaluation on a financed car doubly expensive. A successful challenge closes the gap, and if the agreement itself had hidden commission you may also have a separate car finance claim.
If the number looks low
You don't have to accept it, and the first offer is often not the best offer — the regulator said as much. Read our step-by-step guide to challenging a write-off offer that's too low, or have the valuation checked professionally:
You can challenge your insurer yourself for free, and escalate to the Financial Ombudsman Service at no cost. If you'd rather our partner Allegiant Finance Services handled it, their success fee is between 18% and 36% including VAT of the compensation recovered — and only if you win.
Frequently asked questions
Is the payout based on what I paid for the car?
No. It's based on the car's market value immediately before the damage. If you bought well, the payout can be more than you paid; on a nearly-new car that has depreciated, it can be less. What matters is the cost of replacing it today, not the price on your receipt.
Do I get more if I only had the car a few weeks?
Not automatically — the pre-accident value rule still applies. Some policies include new-car replacement in the first year or two; check your policy schedule, because where it applies the insurer should replace the car rather than pay out its depreciated value.
Will I get my excess back?
Your excess is deducted from the settlement. If the accident was another driver's fault, the excess is normally recovered from their insurer alongside the rest of your losses.
Can I keep the car and still get paid?
Often, for Cat S and Cat N cars — the insurer pays the pre-accident value minus the salvage value and the car stays with you, carrying its category marker. Cat A and B cars cannot be kept.
The settlement was years ago. Is it too late to question it?
Not necessarily. A complaint can normally be considered within six years of the settlement or, if later, three years from when you realised it was too low. But once an insurer issues a final response you have six months to reach the Ombudsman, so don't sit on it.
