Car Depreciation Damage Calculator
A scratch today can cost thousands at trade-in. Here's the math.
Depreciation Impact Estimator
| Car value (clean) | $30,000 |
| With minor unrepaired damage (scratch/dent) | $27,000–$28,500 (5–10% hit) |
| With accident history on Carfax | $22,500–$25,500 (15–25% hit) |
| With frame damage reported | $15,000–$21,000 (30–50% hit) |
| Value lost — minor scratch, unrepaired | $1,500–$3,000 |
CarShake helps you avoid the depreciation hit by documenting pre-existing condition at handover — so someone else's damage doesn't become your Carfax entry.
Why cosmetic damage hurts resale value
When a dealer appraises your trade-in, cosmetic condition is the first thing they evaluate. A car with visible scratches or dents signals "this owner didn't care" — and the dealer mentally deducts for everything else they assume was neglected: oil changes, tire rotations, brake pads. A single visible scratch can trigger a cascade of value deductions totaling 5–15%.
Prevention beats repair
The best way to protect your car's value is to never incur the damage in the first place — or to document its absence so thoroughly that someone else's negligence can't stick to your car's history. CarShake gives you that defense: a 60-second guided scan before every handover, producing a timestamped, geotagged condition report you can produce months later if a surprise scratch appears.
