What is replacement cost vs actual cash value?
It depends on what your declarations page says. Replacement cost vs actual cash value are the two valuation bases a property policy uses to settle a loss: replacement cost pays today's rebuild cost; actual cash value pays that figure minus depreciation (IRMI). On a 20-year-old roof at end-of-life, ACV settles for a fraction of a new one.
Replacement cost and ACV are the standard property-insurance valuation pair. The International Risk Management Institute defines replacement cost as 'the cost to replace the damaged property with materials of like kind and quality, without any deduction for depreciation', with ACV as the matched-pair concept. On a standard HO-3 homeowners policy, the dwelling is covered on a replacement-cost basis; personal property defaults to ACV unless a replacement-cost contents endorsement is added. Example: a 20-year-old asphalt-shingle roof destroyed by hail. On replacement cost the policy pays the cost to install a new roof today; on ACV it pays that figure minus depreciation for two decades of wear.
Where this catches homeowners out
The line that says 'replacement cost' or 'actual cash value' on your declarations page usually goes unread until a claim. A non-renewal notice is one of the few times a homeowner looks at it twice. When shopping a replacement policy, the quote that comes back cheaper often turns out to be on an ACV basis, not because the carrier said so out loud but because the form changed.
At claim time the consequence shows up. IRMI defines actual cash value as replacement cost less depreciation, with the deduction calculated from age and wear. On an ACV policy a 20-year-old roof damaged in a fire pays at a depreciated value, not at the cost of putting on a new one. The same fire on a replacement-cost policy pays the cost to rebuild today, with no depreciation deducted.
If you just got a non-renewal letter and the cheapest replacement quote is materially below the one you had, check the loss-settlement basis before signing. The Insurance Information Institute identifies three valuation methods on a homeowners policy: actual cash value, replacement cost, and guaranteed replacement cost. FAIR Plan dwelling forms in most states are written on the first; a standard open-peril HO-3 is usually written on the second.
How replacement cost and ACV are calculated
The contract language sets the basis. On an HO-3, the standard ISO form puts the dwelling (Coverage A) and other structures (Coverage B) on a replacement-cost basis by default; personal property (Coverage C) defaults to actual cash value unless the insured endorses 'replacement cost on contents.' On a DP-1, both are typically ACV. On an HO-5, dwelling and contents are both on a replacement-cost basis. The peril basis is a separate axis on the same form and is often confused with the valuation basis at intake.
IRMI defines replacement cost as 'the cost to replace the damaged property with materials of like kind and quality, without any deduction for depreciation.' No haircut for age, wear, or obsolescence; the carrier pays the current cost to rebuild at like-kind-and-quality construction. The Insurance Information Institute identifies a third option that shows up on a quote alongside RC and ACV: guaranteed (or extended) replacement cost, which lets the carrier exceed the dwelling limit by a stated percentage if rebuild costs overshoot the policy.
Actual cash value is the harder calculation. IRMI lists three settled methods courts and adjusters use to fix it: replacement cost minus depreciation; fair market value; and the broad evidence rule, meaning any relevant factor a reasonable adjuster would weigh (age, condition, obsolescence, comparable sales, repair history). The applicable method varies by state and by contract. Many policies define ACV explicitly; many leave it open and have it litigated.
Two contract triggers matter at claim time. Most replacement-cost contracts pay the ACV of the loss first and release the depreciation holdback, known as recoverable depreciation, only after the insured actually rebuilds within a stated window (often 180 days or two years). Coinsurance still applies: under-insuring the dwelling below the carrier's replacement-cost threshold, usually 80%, reduces even a partial-loss settlement to the coinsurance fraction.
Why it matters
The basis your policy pays on decides what you can actually rebuild after a loss, and the gap is widest where coverage is hardest to find. If you just got a non-renewal notice, this is the number that changes silently when you replace the policy.
If the only quote you can get is from a FAIR Plan, the dwelling will usually be written on a basic dwelling form (DP-1 style) that pays actual cash value, not replacement cost. Pairing that with a difference-in-conditions policy is the route many homeowners take to restore replacement cost and add back the perils the FAIR Plan excludes.
- Coastal or wind-exposed homes often carry an ACV endorsement on the roof for wind and hail, even when the rest of the dwelling is on replacement cost. Older roofs are the common trigger.
- Investor and rental dwellings often run on DP-1 (basic, ACV) or DP-3 (special, RC) forms instead of an HO-3. The same fire claim settles for very different dollars depending on which one is on the contract.
- Mortgaged homes: lenders typically require coverage at least equal to the loan balance, which may be lower than the home's full rebuild cost. A policy can be replacement cost and still be underinsured.
To check your own situation, read the declarations page (the "dec page") at the front of your policy. It lists the coverage-form designation (HO-3, HO-5, DP-1, DP-3) and states "replacement cost" or "actual cash value" next to each coverage line. If a non-renewal notice prompted the question, the next steps are on the non-renewal page.
How to check which basis your policy uses
- Find your declarations page, usually the first one to three pages of the policy. It lists your dwelling limit, the form code (HO-3, HO-5, DP-1, DP-3), and the loss-settlement basis.
- Look for the exact words 'replacement cost', 'actual cash value' or 'ACV', and 'guaranteed' or 'extended replacement cost'. Some policies use one basis for the dwelling and a different basis for the roof or contents.
- If the basis isn't obvious, email your agent and ask plainly: is Coverage A on a replacement-cost or ACV basis, and what about the roof? A verbal answer doesn't help at claim time.
- Compare your dwelling limit to the current rebuild cost, not the market price or the tax-assessed value. Rebuild cost is what a contractor would charge today to put the same house back in the same place.
- If you're on a FAIR Plan, check the basis carefully: most pay on ACV by default, and a difference-in-conditions policy is the usual route to close the gap.

Frequently asked questions
What is 'guaranteed replacement cost'?
Guaranteed (or extended) replacement cost pays above the policy's stated dwelling limit if rebuild costs run higher than expected, usually up to 125% or 150% of the limit (Insurance Information Institute). Plain replacement cost is capped at the limit; ACV is capped at depreciated value.
How do I tell whether my current policy is replacement cost or actual cash value?
Check your declarations page near 'Coverage A' or 'loss settlement.' Wording of 'actual cash value' or 'ACV' means depreciation is deducted at claim time; 'replacement cost' or 'RCV' means it isn't. Both terms are formalized by IRMI and used industry-wide.
Will my mortgage lender accept an actual cash value policy?
Most lenders require coverage at least equal to the loan balance and many require replacement-cost dwelling coverage; the requirement is set by the servicer, not by state law. Read the insurance clause in your loan documents before binding an ACV-only policy, or your servicer may force-place a replacement-cost policy at your expense.
On an HO-3 policy, is the dwelling settled on replacement cost or ACV?
Replacement cost by default for the dwelling on a standard HO-3; personal property defaults to actual cash value unless endorsed (IRMI). Carriers vary those defaults by endorsement, so the declarations page is the source of truth.
What is recoverable depreciation on a replacement-cost claim?
Recoverable depreciation is the amount a carrier withholds from an initial replacement-cost settlement until the insured actually rebuilds (IRMI defines RC as 'no deduction for depreciation'). Most contracts release it only after rebuild, within a stated window of 180 days to two years.
Does the broad evidence rule apply in every state?
No. IRMI lists it as one of three settled ACV methods, alongside replacement cost minus depreciation and fair market value. Which one governs a given loss depends on state law and the contract's own ACV definition.
Does a FAIR Plan pay replacement cost or actual cash value?
It varies by state and by the form the plan writes; many FAIR Plans pay actual cash value on the dwelling by default, others offer replacement cost as an option. The declarations page states the basis. Pairing the FAIR Plan with a difference-in-conditions policy is the common route to restore replacement cost when the plan does not.
What if my policy uses ACV and only my roof is damaged?
The carrier pays the roof's depreciated value, not the cost of a new roof. With a 20-year-old roof on a 25-year life, the deduction can be steep.
Is replacement cost always better than actual cash value?
For the claim payout, almost always yes. ACV runs a lower premium, but the gap at claim time is often many times the annual saving.
