4.4 Replacement Cost vs. ACV and Loss Settlement in Homeowners

How Homeowners Losses Are Settled

The amount paid on a homeowners claim depends on the valuation basis of the coverage and on the 80% coinsurance / replacement-cost condition in the loss settlement clause. This is the most numerically tested topic on the national portion.

• Actual Cash Value (ACV) = Replacement Cost − Depreciation. Personal property (Coverage C) is settled on ACV unless a replacement-cost endorsement is added.
• Replacement Cost (RC) = the cost to repair/replace with new materials of like kind and quality, no deduction for depreciation. The dwelling (Coverage A) is settled on RC if the insured-to-value condition is met.

The 80% Replacement-Cost Condition

To receive full replacement cost on a partial dwelling loss, the insured must carry Coverage A equal to at least 80% of the dwelling's full replacement cost at the time of loss. If they do, partial losses are paid at full RC up to the limit, with no depreciation. If they carry less than 80%, the loss is settled at the greater of (a) ACV, or (b) the coinsurance-style formula:

Payment = (Carried Limit ÷ Required Limit) × Loss − Deductible

where Required Limit = 80% × full replacement cost. The insured never collects more than the policy limit, and a total loss is generally paid at the policy limit (subject to state valued-policy laws).

Worked Example — Underinsured Dwelling

A home has a replacement cost of $400,000. The owner carries Coverage A = $240,000. A covered fire causes a $100,000 partial loss. Deductible = $1,000.

1. Required limit = 80% × $400,000 = $320,000.
2. Did-carry ÷ should-carry = $240,000 ÷ $320,000 = 0.75.
3. RC formula payment = 0.75 × $100,000 = $75,000 − $1,000 deductible = $74,000.
4. Compare to ACV: if depreciation on the damaged portion is 20%, ACV = $80,000 − $1,000 = $79,000.
5. The insured collects the greater of the two = $79,000.

Because the owner insured to only 75% of value (below the 80% requirement), the carrier applies the penalty formula but still guarantees at least ACV.

Worked Example — Properly Insured Dwelling

Same $400,000 replacement-cost home, but now the owner carries Coverage A = $340,000 (above the $320,000 / 80% requirement). Same $100,000 fire loss, $1,000 deductible.

• Insured-to-value test passed → loss paid at full replacement cost: $100,000 − $1,000 = $99,000. No depreciation, no penalty.

Best practice: carriers strongly encourage insuring to 100% of replacement cost and adding a Guaranteed/Extended Replacement Cost endorsement, which pays an additional 25%-50% over the limit if rebuild costs spike (e.g., post-disaster demand surge).

Coverage C (Personal Property) Settlement

Under a replacement-cost contents endorsement, the insurer typically advances ACV first and pays the withheld depreciation (recoverable depreciation) once the insured actually repairs or replaces the item and submits receipts.

Two settlement traps round out this topic. First, roofs: many carriers now schedule roof claims on an ACV/roof-payment-schedule basis even on a replacement-cost dwelling, so an old roof damaged by hail pays depreciated value, not full replacement. Second, valued policy laws: in some states, a total loss to the dwelling by a covered peril must be paid at the full Coverage A limit regardless of actual replacement cost, overriding the usual replacement-cost-or-ACV calculation. The coinsurance/80% formula applies to partial losses; a statutory valued-policy total loss simply pays the face amount.

The 80% Coinsurance-Style Condition on Buildings

Homeowners building losses (Coverage A and B) settle at replacement cost without deduction for depreciation only if the insured carries at least 80% of the full replacement value at the time of loss. Carry less, and the insurer pays the greater of (a) ACV or (b) the coinsurance-formula amount: (amount carried ÷ 80% of replacement cost) × loss, then minus the deductible, capped at the limit. The denominator is always 80% of replacement value, not the full value — a common arithmetic trap.

Worked Example — Underinsured Dwelling

Replacement cost of the home is $400,000. The insured carries $280,000. A windstorm causes a $60,000 loss; deductible $1,000.

1. Required amount = 0.80 × $400,000 = $320,000.
2. Carried ($280,000) is less than required, so coinsurance penalty applies.
3. Recovery = ($280,000 ÷ $320,000) × $60,000 = 0.875 × $60,000 = $52,500.
4. Less deductible = $51,500 paid.

The insured eats the $8,500 difference as a coinsurance penalty for under-insuring.

Worked Example — Properly Insured Dwelling

Same $400,000 home, but the insured carries $340,000 (above the $320,000 requirement). The same $60,000 loss settles at full replacement cost: $60,000 − $1,000 = $59,000, with no penalty, because the 80% test is met. Above 80%, partial losses are paid in full up to the limit.

Coverage C Personal Property: ACV by Default

Unless a Personal Property Replacement Cost (HO 04 90) endorsement is added, Coverage C settles at ACV — replacement cost minus depreciation. With the endorsement, contents pay at replacement cost (subject to the special category sub-limits). The exam frequently pairs a building loss settled at RC with a contents loss settled at ACV on the same claim to test whether you remember that personal property is ACV by default even on an HO-3 or HO-5.
