Valuing the loss
What a car is worth after an accident
How much resale value a repaired vehicle actually loses, what drives the size of the drop, and why the same accident costs one owner $600 and another $6,000.

The short answer
A repaired vehicle typically loses somewhere between 5% and 25% of its pre-accident value, with the size of the drop driven mainly by how expensive the repair was relative to the car's value, whether structural repair was needed, and how new and low-mileage the vehicle is.
The honest answer is a range, because the same collision produces very different losses on different cars. What follows is what actually drives the number.
The headline ranges
| Situation | Typical loss |
|---|---|
| Minor cosmetic repair, no structure | 3–8% |
| Moderate repair, panels replaced | 8–15% |
| Major repair with structural work | 15–25% |
| Near-total repair on a newer vehicle | 25%+ |
On a $30,000 car, that is roughly $900 at the bottom and over $7,500 at the top.
These are ranges, not promises. Below is what moves you within them.
What actually drives it
1. Repair cost relative to the car's value
The single strongest factor, and the one a buyer reads directly off the history report, because the report shows the damage amount.
A $9,000 repair on a $30,000 car reads as serious. A $1,500 repair on the same car reads as a parking-lot incident. Same vehicle, very different discounts.
This is why any method that applies a flat percentage of repair cost is wrong in both directions: it produces trivial numbers on cheap repairs to expensive cars, and absurd numbers on expensive repairs to cheap ones.
2. Structural or frame repair
The largest single step change. "Structural damage" on a history report is the phrase that empties a buyer pool.
It is also the line between "this car had an accident" and "this car had a serious accident" in the mind of every dealer appraiser. Certified pre-owned programmes routinely exclude structurally repaired vehicles outright, which removes an entire retail channel and pushes the car towards auction, a materially lower price.
Check your repair invoice for frame, unibody, rail, apron, pillar, core support or sectioning.
3. How new the car is
A one-year-old car has the furthest to fall. Its buyers are paying a premium for as-new condition and have plenty of clean alternatives at the same price.
By twelve to fifteen years old, buyers are pricing mechanical condition far more than provenance, and the same accident costs proportionally less.
4. Mileage against expectation
A five-year-old car with 30,000 miles is a premium example, and the accident record destroys precisely the premium. The same car with 95,000 miles is already being bought on price.
Note what this is not: a reason to zero out the claim. The insurer's 17c formula reduces the loss to zero at 100,000 miles, which asserts that a high-mileage car suffers no accident discount at all. Nothing in the market supports that.
5. What the car is
Premium and enthusiast buyers screen harder on history. Someone cross-shopping six clean examples of a three-year-old German saloon will simply take a clean one. Someone shopping a high-supply economy car on price weighs the discount differently.
6. Parts and repair quality
Aftermarket or salvage parts get discounted on top of the accident record itself, and so does any visible imperfection, paint mismatch, an uneven panel gap, overspray on trim. These are worth photographing, because unlike the history record they are concrete and easy for an adjuster to verify.
7. Whether it already had an accident
If the car already carried a reported accident, only the incremental loss from this one is claimable. Claiming the full step from clean overstates it and is easy to defeat.
Why the drop is permanent
It does not fade with time in the way people expect. The record stays on the report for the life of the vehicle, and every subsequent buyer sees it. What changes is that the loss shrinks in dollar terms as the car depreciates, 15% of $30,000 is $4,500; 15% of $9,000 is $1,350.
Which is an argument for claiming sooner rather than later. Your loss is measured against the pre-accident value at the time of the collision, and a claim brought promptly is also simply more credible.
The two ways to find your number
Comparable listings. Search your exact year, make, model and trim. Find several clean-history listings and several with a reported accident, adjust for the mileage difference, and read the spread. This is what an appraiser does and it is the most persuasive evidence available to you, because it replaces opinion with the market.
A documented method. Apply the factors above to your specific vehicle. Our calculator does this and shows every step, and the full methodology is published including the curve shape and every coefficient. If you supply comparables, it blends the market reading in at 40% against the model.
What it is not
It is not what the insurer will offer you. Their opening number comes from a formula that caps your loss at 10% of the car's value before reducing it twice more, which on many claims lands at a fraction of the market reality, and on high-mileage cars lands at zero.
The gap between those two numbers is the entire negotiation. See both for your own car. It takes about three minutes and costs nothing.
