How insurers calculate actual cash value on a totaled car

Last reviewed October 19, 2026 · General information, not legal advice. Rules vary by state and by policy.

"Actual cash value" (ACV) is what your car was worth just before the loss. Insurers don't guess it; they assemble it from market data and adjustments, usually with valuation software from vendors such as CCC, Mitchell or Audatex. Knowing the pieces tells you where to look for mistakes.

The building blocks

1. Your car's profile: year, make, model, trim, drivetrain, mileage, options and condition.
2. Market data: comparable vehicles for sale or recently sold near you, dealer quotes, or a database. State rules list what's allowed. Florida, for example, permits two or more local comparables from the prior 90 days, a recognized industry source such as a database or guidebook, or quotes from two or more licensed local dealers [1].
3. Adjustments: each comparable is adjusted for differences from your car (miles, options, sometimes condition), and the results are combined.
4. Taxes and fees: depending on your state and policy, sales tax, title and registration may be added.

What states require of those adjustments

• California: adjustments must be discernible, measurable, itemized and appropriate in dollar amount, and condition deductions aren't allowed unless the documented condition is below average for that year, make and model [2].
• Washington: offers must be based on itemized and verifiable dollar amounts, and insurers must consider relevant information you supply [3].
• New York: the minimum cash offer must follow an approved method, such as an average of approved valuation manuals, a qualified dealer quote within 25 miles, or an approved statistically valid database [4].

Taxes and fees

California requires the settlement to include applicable taxes and one-time transfer fees [2]; Washington requires applicable government taxes and fees [3]; New York regulators have said ACV includes sales tax paid or payable unless the law or policy defines it otherwise [5]. Florida lets insurers defer sales tax until you actually incur it [1]. Check your state's rule.

Where ACV goes wrong most often

• Wrong trim or drivetrain pulls in cheaper comparables
• Overstated mileage
• Missing options or packages
• Unsupported condition deductions
• Blanket "projected sold" or "typical negotiation" cuts
• Distant or unverifiable comparables
• Tax and fees left out
