Every home insurance policy contains a quiet decision about what a dollar of damage is worth, and that decision, the valuation basis, does more to shape a claim payment than almost any limit on the declarations page. Two policies with identical dwelling limits can pay very different amounts for the same fire depending on whether they settle at replacement cost or actual cash value, and several other bases, functional replacement, agreed value, stated amount, appear in particular corners of the market. This page defines each valuation concept, where it is typically used, and what choosing it means on the day of a loss.
Replacement cost and actual cash value
Replacement cost value pays what it costs to repair or replace the damaged property with materials of like kind and quality at today's prices. Actual cash value starts from the same figure and subtracts depreciation for age and wear, so a fifteen-year-old roof settles at a fraction of its replacement price. The gap between the two is the single biggest valuation choice in the policy. The Insurance Information Institute, discussing contents coverage, puts the premium difference at about 10% more for replacement cost, and the same tradeoff logic runs through dwelling and roof settlement terms.
Functional replacement and older homes
Functional replacement cost pays to repair with modern, functionally equivalent materials rather than exact reproductions: drywall standing in for plaster, standard millwork for hand-carved trim. It exists because true reproduction of older construction can cost far more than the home's value, and insurers use it to make older housing stock insurable at reasonable premiums. Owners of historic homes should know which basis their policy uses before a loss, because the difference between reproduction and functional equivalence is the difference between restoring a period interior and replacing it.
Market value is not an insurance number
A home's market value bundles land, location and demand, none of which burns down. Insurance valuation concerns the cost of rebuilding the structure, which can sit far above market value in depressed areas and far below it in expensive ones. Consumer guidance from the CFPB frames homeowners coverage around repairing or rebuilding the home itself, and the legal definitions collected by Cornell's Legal Information Institute draw the same line for hazard coverage: the insured interest is the structure, not the real estate market around it.
Agreed value, stated amount and the fine print
In some corners of the market, notably older mobile homes and unusual properties, policies are written on an agreed value or stated amount basis, where insurer and owner fix the settlement figure when the policy is issued rather than measuring loss afterward. The certainty is real but so is the ceiling: the agreed figure is what a total loss pays regardless of what rebuilding costs that day. Whatever the basis, the practical homework is the same: reread the valuation clause whenever construction costs move, so the number in the policy still matches the world.
Questions people ask about home insurance valuation
What is the difference between RCV and ACV?
Replacement cost value pays today's cost to repair or replace with like kind and quality. Actual cash value subtracts depreciation for age and wear from that figure, so older components settle for less. The choice between them is the core valuation decision in the policy.
What is functional replacement cost?
A basis that repairs with modern, functionally equivalent materials rather than exact reproductions, common for older homes where reproducing original plaster, trim or masonry would cost far more than the home is worth.
Should my coverage equal my home's market value?
No. Market value includes land and location, which a loss never destroys. The right anchor is the cost of rebuilding the structure at current construction prices, which can be higher or lower than what the home would sell for.
Where are agreed value policies used?
Mostly for property that standard valuation handles badly, such as older mobile homes and unusual or historic structures. Insurer and owner fix the settlement figure at issue, which trades away inflation protection for certainty about what a total loss pays.
