What actual cash value means on a claim
Actual cash value is what your damaged property was worth immediately before the loss, in the condition it was actually in. Replacement cost is what it takes to put new property in its place. The gap between the two is depreciation, and on most claims it is the single largest number on the worksheet.
Three definitions of ACV are in use across US jurisdictions, and which one applies to you is a matter of state law and policy wording:
- Replacement cost less depreciation. The method this calculator uses and the one adjusters actually compute. Age over expected life, applied straight-line.
- Fair market value. What a willing buyer would pay a willing seller for the used item. Used for some personal property and vehicles.
- The broad evidence rule. Any relevant evidence of value, including all of the above, plus obsolescence, income the property produced, and the cost to reproduce it. Several states apply this by court decision.
The three rarely give the same answer. A fifteen-year-old asphalt shingle roof has essentially no market value on its own but a clear age-over-life depreciation figure, which is why the age-over-life method dominates building claims and the market-value idea dominates contents and vehicles.
The formula, term by term
You start with replacement cost — not what you paid, and not what the item is listed for online. It is the installed cost today of new property of like kind and quality: shingles plus underlayment plus tear-off plus labour, or a comparable washing machine plus delivery and hook-up. On building components it is drawn from a construction pricing database, and it moves with material and labour markets rather than with anything about your item.
You then compute the fraction of life used. Divide effective age by expected useful life and cap it at 1, because nothing depreciates past fully depreciated. The cap matters: an item at 30 years against a 20-year life is not 150% depreciated and does not have a negative value.
Effective age is where judgement enters. Two roofs installed the same week are not equally worn if one faces south in Phoenix and the other is shaded in Portland, and adjusters legitimately adjust for that. This calculator exposes the adjustment as a multiplier so you can see what a condition call is worth in dollars. A judgement that an item is worse than average for its age is contestable evidence, not arithmetic — photographs, maintenance invoices and a roofer's inspection report are how you contest it.
Salvage or residual value is the fraction of replacement cost the item never loses. Many published guides depreciate to zero; others floor at 10% or 20% on the reasoning that even a worn item has some remaining service. Because the salvage percentage reduces the depreciable base rather than the replacement cost, a 10% floor on a $20,000 item means the most you can ever be depreciated is $18,000.
Two numbers come out the other side. Actual cash value is what the carrier owes now. Recoverable depreciation is the rest of the replacement cost, and on a replacement-cost policy the carrier owes it once you have actually done the work and sent the invoice. On an ACV-basis item it is not owed at all.
Worked example: a 12-year-old roof on a replacement-cost policy
Hail destroys the roof on your house. The contractor's estimate to tear off and replace is $12,000. The permit shows the roof was installed 12 years ago. Your carrier's depreciation guide gives architectural asphalt shingles a 25-year expected life, depreciates to zero salvage, and the adjuster agrees the roof was average for its age. Your deductible is $1,000 and the dwelling is written on replacement cost.
- Effective age. 12 years × 1.0 (average condition) = 12 years.
- Fraction of life used. 12 ÷ 25 = 0.48.
- Depreciable base. With no salvage, the full $12,000 is depreciable.
- Depreciation. $12,000 × 0.48 = $5,760.
- Actual cash value. $12,000 − $5,760 = $6,240.
- First check. $6,240 − $1,000 deductible = $5,240.
- Recoverable depreciation. $12,000 − $6,240 = $5,760, released when the roof is finished and invoiced.
- Total you collect. $5,240 + $5,760 = $11,000, which is the $12,000 job less the one $1,000 deductible.
Notice that the deductible is applied once, not twice. The total is always replacement cost minus one deductible on a replacement-cost settlement, however the payments are split.
Now suppose the adjuster calls the roof worse than average and applies a 1.2 condition multiplier. Effective age becomes 12 × 1.2 = 14.4 years, the fraction of life used becomes 14.4 ÷ 25 = 0.576, and depreciation rises to $12,000 × 0.576 = $6,912. Your first check falls from $5,240 to $12,000 − $6,912 − $1,000 = $4,088. On a replacement-cost policy the total is unchanged at $11,000, because the extra depreciation is recoverable — but you are $1,152 further out of pocket while the work is underway. On an ACV-only roof endorsement that same condition call costs you the full $1,152 permanently.
How to read the result
The gap between the first check and the total is the money you have to float. On a replacement-cost policy the carrier hands you actual cash value up front and holds the depreciation until the work is complete. That is a cash-flow problem, not a coverage problem — but on a $40,000 rebuild with 45% depreciation it is an $18,000 cash-flow problem, and it is the reason contractors ask about your policy basis before they schedule.
Depreciation above about 60% of replacement cost tells you the item was near the end of its life. That is not a reason to argue — it is arithmetic on the age you supplied — but it is a reason to check two things. First, is the useful life the carrier applied right for this product? A 50-year standing-seam metal roof and a 20-year three-tab shingle roof do not share a depreciation table. Second, is the age right? Carriers sometimes date from the property's construction rather than from the component's install date, and a permit or an invoice settles it.
If the actual cash value comes out below your deductible, the first check is zero. On a replacement-cost policy the carrier still owes the balance after repairs, so the claim is worth filing. On an ACV-only item the claim produces nothing and filing it may still count against your loss history — that is the calculation the deductible break-even calculator makes explicit in the auto context, and the same logic applies here.
Watch for ACV-only endorsements on the very components most likely to fail. Roof schedules that step a roof onto actual cash value after ten or fifteen years are now common in hail-prone states, and they can appear on a policy whose dwelling coverage is otherwise replacement cost. The declarations page names them; the premium saving is real and so is the exposure.
Expected useful lives commonly applied to building components
| Component | Typical life (yr) | Depreciation after 10 yr, no salvage |
|---|---|---|
| Three-tab asphalt shingles | 20 | 50% |
| Architectural asphalt shingles | 25 | 40% |
| Wood shake roof | 25 | 40% |
| Standing-seam metal roof | 50 | 20% |
| Vinyl siding | 30 | 33.3% |
| Interior paint | 8 | 100% (capped) |
| Carpet | 10 | 100% (capped) |
| Water heater | 12 | 83.3% |
| Central air conditioner | 15 | 66.7% |
| Kitchen appliances | 12 | 83.3% |
The third column is 10 ÷ life, capped at 100%, which is exactly what the calculator computes at a salvage percentage of zero.
Where ACV settlements go wrong
- Depreciating labour. Whether the labour portion of a repair can be depreciated is contested and several states restrict it. If the estimate depreciates tear-off and installation as well as materials, ask on what authority.
- Using the building's age instead of the component's. A 40-year-old house can have a 6-year-old roof. Produce the permit, the invoice or the manufacturer's date stamp.
- Accepting a useful life that does not match the product. The difference between a 20-year and a 25-year life on a 12-year-old roof is 60% versus 48% depreciation — on a $12,000 roof, $1,440.
- Missing the deadline on recoverable depreciation. Policies set a window — often 180 days or one year from the loss — to complete the repair and claim the holdback. Miss it and the recoverable depreciation is simply gone.
- Assuming the whole policy settles the same way. Dwelling on replacement cost, roof on a schedule, contents on ACV, and outbuildings on ACV is an ordinary combination. Read each line of the declarations page.
- Confusing depreciation with betterment. If the repair genuinely improves the property beyond its pre-loss condition — a code upgrade, a better material — that is a separate adjustment and it is not what the age-over-life calculation is measuring.
Recoverable depreciation is a policy promise, not a favour
On a replacement-cost policy the carrier's obligation is the full cost to replace, subject to the limit and the deductible. The holdback exists to stop the policy from paying more than the loss when the insured never repairs — it is an anti-windfall device, not a discount. Once you have completed the repair and submitted the final invoice, the depreciation is owed. Keep the contract, the paid invoices and the photographs; those three documents are what release it. If the actual repair cost comes in below the original estimate, the carrier owes the actual cost, not the estimate, so keep the paperwork accurate.
How ACV interacts with the rest of the policy
Actual cash value is one of three things that shrink a settlement, and they compound. The first is the deductible, which on a wind or hail loss is often a percentage of Coverage A rather than a flat amount — the percentage deductible calculator converts that to dollars, and 2% of a $400,000 dwelling is $8,000. The second is depreciation, which this page computes. The third is the coinsurance or insurance-to-value provision, which reduces even a partial loss when Coverage A is set below the required percentage of replacement cost; the coinsurance penalty calculator works that reduction, and it applies before the deductible.
Getting Coverage A right is upstream of all of it. If the dwelling limit is short, the Coverage A calculator and the extended replacement cost calculator are where to start, because no amount of arguing about depreciation fixes a limit that cannot fund the rebuild. For contents, the personal property calculator sizes the limit, and the same ACV-versus-replacement-cost question arises there in sharper form: household goods depreciate fast, so an ACV contents settlement on a total loss is often a small fraction of what refurnishing costs.
Vehicles work differently. A total-loss auto settlement is market value for a comparable vehicle rather than age-over-life depreciation, which is why the total loss settlement calculator is built on comparable sales rather than a life table.
