A total loss after hail is a situation in which the cost of repairing the car exceeds a certain percentage of its value, so the repair is no longer economically justified. The indicator is simple to calculate: repair cost divided by the vehicle's value, times 100. The actual threshold is set by the insurer in the policy conditions, so as a technician or workshop you mainly keep an eye on how close your estimate is to that threshold.
What a total loss is and why hail “produces” one
In a collision, a total loss brings to mind a badly smashed car. Hail works differently. A single dent is minor, but a storm can leave hundreds of them — on the bonnet, roof, wings, doors and pillars all at once. Every panel has to be assessed, some require removing trim, mouldings or glass, and some go for painting or replacement.
As a result, the repair cost grows faster than the car's appearance suggests. The most exposed are:
- older cars with a low market value,
- cars with a large number of dents on the roof and horizontal panels,
- cars with aluminium panels or with damage that requires painting,
- cars where access to the dents requires many removals.
A mechanically sound car after hail can therefore be declared a total loss. This is a frequent source of misunderstandings with the customer, who sees “just a few dimples in the metal”.
How to calculate the total loss percentage
There is one formula, and it is worth keeping it in mind at every inspection:
damage percentage = (repair cost ÷ vehicle value) × 100
Two numbers in this formula decide everything:
- Repair cost — the full estimate, not just the PDR repair. Include the flat rate for the dents, surcharges for larger dents (41–70 mm and above 70 mm), aluminium, paintwork, removals and part replacement.
- Vehicle value — the market value of the car before the damage. In practice the insurer determines it using its own methodology, so your working value may differ from it.
If you calculate the cost net in one place and the value gross in another, the result will not be comparable. Stick to one convention and record where the car's value came from.
We cover how to build the estimate itself in the article how to estimate hail damage step by step.
Warning thresholds — how to read the result
The percentage on its own says little without a point of reference. In WE-PDR we divide the result into four colour bands. These are the app's working thresholds, not a legal rule or a specific insurer's policy:
| Band | Percentage of vehicle value | What it means in practice |
|---|---|---|
| Green | 0–50% | Repair economically justified, a comfortable margin. |
| Yellow | 51–60% | Watch every additional line in the estimate. |
| Orange | 61–69% | High risk — further surcharges may tip the balance. |
| Red | ≥70% | Total loss zone in the app's default setting. |
The total loss threshold differs between insurers and policies. That is why you should treat the bands as an early warning and take the final point of reference from the policy terms of the customer's policy.
The most useful thing is not the colour itself but the margin to the threshold — the amount you can still add to the estimate before the repair crosses the line. The total loss threshold in WE-PDR shows this margin live, with every change in the assessment.
Why the estimate “grows” and how not to be caught out
The estimate from the first inspection is rarely final. After removing the headliner or covers, dents often appear that were not visible under the lamp. On top of that come panels which, on closer inspection, qualify for painting or replacement.
If the first estimate comes out in the orange band, be prepared for a correction to push it into the red. Practical rules:
- Assess the whole vehicle straight away, not just the most visible panels. The roof and horizontal panels usually carry the most dents.
- Count the dents on the whole car together. With a flat rate from a band table, it is the total of dents ≤40 mm from all panels that determines the price band. Above 100 dents, a fixed amount per dent is added — in the WE-PDR default price list, PLN 13.50 net.
- Enter removals and replacements straight away, not “at the end”. These are what most often shift the result by a whole band.
- Record the source of the vehicle's value in the job, so that in the conversation with the insurer you do not have to argue about it from scratch.
What to do when the estimate approaches the threshold
When the damage percentage enters the orange or red band, do not stop working on the estimate — finish it properly. The decision on classifying the claim is made by the insurer, and your job is to give it honest numbers.
Check in turn:
- Whether every panel has the right repair method. Sometimes replacing a small panel works out cheaper than repairing it with PDR and lowers the total. More in the article PDR repair or panel replacement.
- Whether the vehicle's value is up to date and reflects the condition of the car before the damage.
- Whether the estimate contains duplicates — for example a removal counted on two panels.
- Whether the customer knows what the result means. It is better to warn them early than to explain yourself after the insurer's decision.
In a conversation with the claims handler, the documentation is your argument: photos, the technical assessment and a calculation with itemised lines. In WE-PDR, the damage percentage and band go into the PDF calculation along with the rest of the estimate, so both sides are looking at the same numbers.
Total loss and the customer's policy
Hail damage is usually covered by comprehensive (own-damage) cover, not by third-party liability — with hail there is no at-fault party whose policy could cover the damage. A customer without comprehensive cover usually pays for the repair themselves, and then the concept of a total loss matters to them only economically: whether the repair is worth its price.
With comprehensive cover, the details — the threshold, how the car's value is determined, how the salvage is settled — are set by the contract. Do not promise the customer an outcome before you have seen the wording of their policy terms. We describe the whole claim process from the workshop's perspective in the article hail damage claims under comprehensive cover.
Checklist: total loss in workshop practice
- Establish the vehicle's value before the damage and record its source.
- Assess all damaged panels, including the roof and pillars.
- Include surcharges for size, aluminium, paintwork, removals and replacements.
- Calculate the percentage: repair cost ÷ vehicle value × 100.
- Check the margin to the threshold, not just the colour of the result.
- Compare the result with the threshold in the policy terms of the customer's policy.
- Give the insurer a complete calculation with photos.
If you calculate this by hand in a spreadsheet, it is easy to make a mistake with every correction. The hail damage calculator in WE-PDR recalculates the cost and damage percentage automatically, from the same data you enter during the inspection.
