How Is ACV Determined for Home Insurance?
An adjuster takes the cost to replace the item new and subtracts depreciation for its age and wear.

How your adjuster gets to a number
The adjuster starts with what it costs today to replace the damaged item or material with something comparable, then subtracts an amount for how old it was and how much life it had left. A ten-year-old roof rated for twenty-five years gets less back than a roof installed last year, even though both suffered the same storm damage. The same logic applies to flooring, appliances, siding, almost anything with a usable lifespan. Insurers often lean on depreciation software or standard tables for this, and two adjusters can land on different numbers for the same item depending on which one they use and what condition they judge it to be in. Ask for the itemized worksheet showing the replacement cost and the depreciation applied to each line. If your policy includes replacement cost coverage, you may recover that withheld depreciation later, once repairs are done.
Check your ACV payout before you settle
If depreciation was estimated high or the condition rating was off, the gap shows up in your check. Comparing coverage now shows whether a policy with better replacement cost terms would serve you next time.
What to do if the ACV offer looks too low
Start by asking the adjuster for the full depreciation worksheet, not just the settlement number. It should list each damaged item, its replacement cost new, the age and expected lifespan used, and the percentage knocked off for depreciation. If the worksheet lists your roof as fifteen years old and it was installed eight years ago, that's a documented error you can dispute with a receipt or permit record. Contractor estimates, product manuals, and photos from before the loss all help establish the true age and condition of what was damaged.
Depreciation applies to materials and labor differently depending on the insurer and the state you're in, so two claims that look identical on paper can settle for different amounts. Some adjusters depreciate labor costs along with materials, which pushes the payout lower than if only materials were depreciated. Ask directly whether labor was depreciated on your claim. If your state restricts that practice or your policy doesn't allow it, the answer to that question changes what you're owed.
If you believe the number is wrong, you don't have to accept it to keep the claim moving. Most policies let you submit your own repair estimates from a licensed contractor as a counter to the insurer's figures. Put the dispute in writing, attach your documentation, and ask for a written response rather than a phone call. Many policies also include an appraisal clause, a process where each side picks an appraiser, the two appraisers pick a neutral umpire, and that panel settles the dollar amount. It costs something to invoke, usually split between you and the insurer, but it exists for exactly this kind of disagreement and doesn't require a lawsuit.
If your policy carries replacement cost coverage, the ACV check you're holding now isn't the end of it. That payout is the depreciated amount, and the withheld portion, what's usually called recoverable depreciation, becomes available once you complete the repairs and submit the receipts. Insurers set a window for claiming it, often a year or two from the date of loss, and miss that window and the money is gone. Check your declarations page for the deadline and keep every invoice from the repair work, because that's what releases the second payment.
Can you negotiate an ACV settlement before repairs start
An ACV offer is a starting point, not a final word. Nothing in a standard policy says you have to accept the first number the adjuster writes down. You can push back with your own documentation at any point before you sign a release, and in most cases signing that release is the only thing that actually closes the claim.
The strongest counter is a second opinion from someone who repairs houses for a living. Get a written estimate from a licensed contractor covering the same scope of damage the adjuster inspected. If the contractor's estimate is higher, ask them to note why, maybe they priced a different grade of shingle, or they found damage the adjuster's report left out. Submit that estimate to the insurer along with photos and any receipts you have for the damaged item. A specific, documented counter carries more weight than a general complaint that the number feels low.
Timing matters here too. Most policies set a deadline for submitting proof of loss and supporting documents, often within 60 days of the loss, though your declarations page and policy wording set the actual number for your state and insurer. Negotiating doesn't pause that clock, so keep filing your paperwork on schedule even while you're disputing the dollar amount. If the adjuster revises the offer after seeing your contractor's estimate, get the new number in writing before you agree to anything.
If the gap between your estimate and theirs doesn't close through back and forth, that's usually when the appraisal clause in your policy becomes the next step, not a lawsuit. Some homeowners also loop in a public adjuster at this stage, someone licensed to represent your side of the claim for a fee, usually a percentage of the final settlement. Whether that fee is worth paying depends on how large the dispute is and how complicated the damage turns out to be.
Before you sign anything
Check your declarations page for the recoverable depreciation deadline and your proof of loss deadline, then compare today's ACV offer against a contractor's written estimate before you settle.
