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.
