The rule in Colorado
Colorado uses a 100% simple percentage threshold to decide when a damaged vehicle must be declared a total loss. Once estimated repair cost reaches 100% of the vehicle's actual cash value (ACV), state law treats it as a total loss — regardless of what the vehicle's salvage value would be.
Worked example — a $10,000.00 vehicle:
Repair estimate: $10,000.00 (100% of $10,000.00). On a $10,000.00 vehicle, repair costs reaching $10,000.00 (100% of ACV) meet Colorado's total-loss threshold.
What this means practically
At 100%, Colorado sets one of the highest bars in the country — insurers are only required to total a vehicle once estimated repairs would cost as much as the car itself is worth, leaving more room for heavily damaged vehicles to be repaired and returned to the road than in most other states.
How Colorado compares nationally
Of the 29 jurisdictions that use a fixed percentage, 27 set a lower bar than Colorado's 100%, 1 uses the same 100%, and 0 set a higher one. Another 22 use the Total Loss Formula instead of any percentage.
Colorado vs. bordering states
| State | Rule | Compared with Colorado |
|---|---|---|
| Colorado | 100% of ACV | — |
| Arizona | Total Loss Formula | Different method |
| Kansas | 75% of ACV | Lower bar — cars total out sooner |
| Nebraska | 75% of ACV | Lower bar — cars total out sooner |
| New Mexico | Total Loss Formula | Different method |
| Oklahoma | 60% of ACV | Lower bar — cars total out sooner |
| Utah | Total Loss Formula | Different method |
| Wyoming | 75% of ACV | Lower bar — cars total out sooner |
Across the state line — Take a $10,000.00 car with a $9,000.00 repair estimate. It is not a total loss in Colorado (100% of ACV), but it is a total loss in Arizona (Total Loss Formula, with an assumed $1,000.00 salvage value). If your accident happened near the Arizona line, check which state's rule actually applies — usually the state where the vehicle is registered and insured.
Who regulates total losses in Colorado
Total-loss rules are enforced by Colorado's insurance regulator. If you think your insurer applied the wrong threshold or undervalued your vehicle, you can file a consumer complaint there. Find the department's contact details in the NAIC directory of state insurance departments, and see how to file a complaint with your state insurance department.

What this page can't tell you
It can't tell you Colorado's threshold with legal certainty — this reflects one compiled secondary review as of mid-2026, not a direct reading of the state's current statute or administrative code, and state rules can change. It also can't tell you what your specific vehicle's ACV or salvage value actually is; for that, see How Insurers Value a Total-Loss Vehicle and run your own numbers through the Total-Loss Offer Audit calculator.
Frequently Asked Questions
What is the total-loss threshold in Colorado?
Colorado uses a 100% simple percentage threshold: if estimated repair cost reaches 100% of the vehicle's actual cash value (ACV), state law treats it as a total loss.
Does Colorado use a percentage rule or the Total Loss Formula?
A percentage rule — specifically 100% of ACV. Some neighboring states use the Total Loss Formula instead, so the same repair estimate can produce a different result just across a state line.
Is this the exact test my insurer will use?
It's the state-law minimum, compiled from a secondary source and one example state regulator's published methodology — not a live read of the current statute, and not necessarily identical to your insurer's own internal total-loss policy, which can be more (but not less) generous. Confirm the current rule with your state insurance department if it matters to your claim.
