Diminished value:
the invisible loss on a Swiss vehicle
Even after a technically perfect repair, an accident vehicle may sell for less. Under German liability law, this commercial diminished value can be recoverable in addition to repair costs if it is justified and quantified.

1. What is commercial diminished value?
A repaired accident vehicle can achieve a lower market price than an accident-free equivalent, even after a technically flawless repair. Buyers pay less and the repaired accident must be disclosed on resale. This real financial loss is commercial diminished value and can be recoverable in addition to repair costs.
Recognised claim
German liability practice has recognised diminished value for decades. Whether it exists and how much it is depends on the particular vehicle and damage. Insurers usually consider it only when a report explains and quantifies it.
2. When does it arise?
- Age and mileage: younger, lower-mileage vehicles tend to lose more. About five years and 100,000 km are rough practical guides, not rigid limits, especially for valuable vehicles.
- Extent of damage: structural and body repairs weigh more heavily than replacement of bolt-on parts.
- Materiality: minor damage such as replacement of a bumper without further damage usually produces no diminished value.
- Marketability and prior damage: desirable vehicles without prior damage may lose more; existing damage can reduce the claim.
3. How is it calculated?
There is no statutory formula. Experts use recognised methods including MFM, Ruhkopf/Sahm and BVSK, considering replacement value, repair costs, damage, age and mileage. The result remains an expert estimate that must be reasoned.
Example
A three-year-old estate car with 60,000 km, replacement value CHF 28,000 and repair costs CHF 9,500 including work to a side panel may, depending on method and market, have diminished value of about CHF 800–1,500. The result may be lower or higher depending on the vehicle and damage.
4. The Swiss market matters
A Swiss-registered vehicle will later be sold on the Swiss used-car market. The diminished value must therefore reflect Swiss market conditions and be stated in CHF, not derived uncritically from German market values.
5. When is there little or none?
- Minor damage without interference with vehicle substance
- Very high age or mileage, although there is no automatic exclusion
- Significant prior damage in the same area
- Economic total loss, where settlement is based on replacement value rather than repair
Common mistake
Insurers seldom volunteer this payment and may reject it with generic references to age or mileage. Have any reduction checked rather than accepting it automatically.
6. How to claim
- Commission an independent report before repair.
- Require a reasoned diminished-value figure based on the Swiss market in CHF.
- Claim it separately from the German liability insurer; it may also accompany notional settlement.
- If reduced, obtain the expert's technical response.
Diminished value: FAQ
Can a Swiss claimant recover diminished value after an accident in Germany?
In principle yes, where German liability law applies and commercial diminished value is justified in the individual case.
How much is diminished value?
It depends on value, age, mileage, marketability and the nature and extent of the damage. An expert estimates and explains it using recognised methods.
Can I recover diminished value without repairing?
In principle yes. It is a separate claim and may also be claimed alongside a notional settlement where justified.
Is a vehicle over five years old excluded?
No. There are no rigid age or mileage limits; the individual vehicle and market determine the result.
Which market applies to my Swiss vehicle?
The Swiss market in CHF is relevant because that is where the vehicle would be sold.
