4.4 Replacement Cost vs. ACV and Loss Settlement in Homeowners

Two Valuation Standards

How a homeowners loss is paid depends on the valuation basis in the loss-settlement condition. Two standards dominate the exam:

• Replacement Cost (RC): The cost to repair or replace with new property of like kind and quality, with no deduction for depreciation.
• Actual Cash Value (ACV): Replacement cost minus depreciation. Most states define ACV as RC − depreciation; some use the 'broad evidence rule' or market value.

In the HO program, Coverage A and B (the structure) are settled on replacement cost if the insured carries adequate insurance, while Coverage C (personal property) is settled on ACV unless a Personal Property Replacement Cost endorsement (HO 04 90) is added.

Worked ACV example: A roof costs $20,000 to replace new. It is 15 years into a 20-year useful life, so it has depreciated 75% (15/20). ACV = $20,000 − $15,000 = $5,000. Under an RC settlement the insurer pays the full $20,000 (subject to the deductible); under ACV it pays $5,000.

The 80% Replacement-Cost Coinsurance Requirement

To earn full replacement-cost settlement on the dwelling, the insured must carry Coverage A equal to at least 80% of the full replacement cost at the time of loss. If the insured carries less, partial losses are paid by the insurance-to-value formula — the larger of ACV or:

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

where Required Limit = 80% × full replacement cost.

Worked Coinsurance Example

A home has a replacement cost of $400,000. The 80% requirement = $320,000. The owner insured only $240,000 and suffers a $60,000 partial loss (no deductible for simplicity):

• Coinsurance ratio = $240,000 ÷ $320,000 = 0.75
• RC-formula payment = 0.75 × $60,000 = $45,000

The insurer pays $45,000; the owner absorbs the $15,000 shortfall as a coinsurance penalty. Note this formula applies only to partial losses on the structure — a total loss is paid up to the policy limit regardless of the 80% test (and many states cap recovery at the face amount).

Loss Settlement Mechanics and Other-Insurance

Holdback / Recoverable Depreciation

Under an RC dwelling settlement, the insurer often pays ACV first and holds back the depreciation until repairs are actually completed. The insured then submits proof of repair to collect the recoverable depreciation. If the insured chooses not to rebuild, recovery is capped at ACV.

Pair-or-Set and Functional Loss

A loss to one item of a pair or set (one earring, one of a matched pair of vases) is settled at the difference between the ACV of the set before and after the loss — the insurer is not forced to replace the whole set or pay for the whole set.

Other Insurance and Deductibles

Split-limit analogy (auto cross-reference): Just as auto liability shows as 100/300/50 (per-person/per-accident/property), homeowners Section II uses a single combined limit per occurrence — do not split it. This is a common distractor on combined P&C exams.

Putting the Numbers Together

Work settlement problems in a fixed order: (1) confirm the peril is covered; (2) determine the valuation basis (RC for dwelling if 80% met, ACV for contents); (3) apply the coinsurance ratio if the structure is underinsured; (4) subtract the deductible last; and (5) check whether other insurance prorates the result. Skipping the coinsurance step or subtracting the deductible too early are the two most common arithmetic errors candidates make under time pressure.

Finally, distinguish a partial loss from a total loss. The 80% coinsurance penalty applies only to partial losses; a total loss pays the lesser of the policy limit or the cost to rebuild, and in valued-policy-law states a total loss by a covered peril pays the full face amount regardless of actual rebuild cost. Reading 'partial' vs. 'total' in the stem tells you whether the coinsurance formula even applies.

Insurance-to-Value Is the Heart of HO Loss Settlement

The 80% replacement-cost requirement exists so insureds cannot shave premium by insuring a house for far less than it costs to rebuild and still expect full payment on the common partial loss. Carry at least 80% of full replacement cost at the time of loss and partial losses settle at full replacement cost; carry less and the insurance-to-value formula pays the greater of ACV or the proportion the carried limit bears to the required limit, minus the deductible.

Worked Underinsurance Comparison

A home with a $500,000 replacement cost requires $400,000 (80%). The owner carries $300,000 and has a $40,000 partial loss.

The insurer pays the larger figure, $30,000, then subtracts any deductible. Because the home was underinsured, the owner absorbs the $10,000 gap - the lesson the exam wants you to internalize before reading partial-vs-total in the next stem.
