Loss Settlement and the 80% Replacement Cost Rule
How much a homeowners claim actually pays depends on the loss settlement provisions, and the dwelling and personal property follow different rules. Buildings under Coverages A and B are settled at replacement cost — with no deduction for depreciation — only if the Coverage A limit equals at least 80% of the dwelling's full replacement cost at the time of loss. Fall below 80% and a coinsurance-style penalty applies: the insured recovers the LARGER of actual cash value or a pro-rata share of replacement cost based on the ratio of insurance carried to insurance required. Insurers also apply a replacement-cost hold-back: on larger losses the carrier initially pays ACV and releases the depreciation hold-back only after repair or replacement is actually completed. Personal property, by contrast, is settled at actual cash value (replacement cost minus depreciation) under the unendorsed form. The ISO HO 04 90 Personal Property Replacement Cost endorsement upgrades contents to replacement-cost settlement, with an age-of-property exception for categories where depreciation-based valuation still governs. HO 23 84 is a variant that grants replacement cost but carves out personal effects such as antiques, fine arts, and collectibles — items that appreciate rather than depreciate — leaving them at ACV or for separate scheduling. Going the other direction, HO 04 81 converts windstorm losses (typically roof-related) to ACV settlement as an underwriting concession. Keeping the limit adequate over time is its own endorsement family. HO 04 11 and HO 04 46 Premises Inflation Guard raise Coverages A through D continuously and pro rata across the term at a scheduled annual percentage. HO 04 20 provides a specified additional amount of insurance above Coverage A, and HO 04 52 lets the insured elect Coverage Locked-in (the limit stays fixed at the declarations amount all term) or Coverage Floating (the limit tracks replacement-cost changes up to a stated cap). HO 03 03 increases Coverage A by a percentage at renewal, and HO 04 47 applies a roof surfacing schedule that reduces roof recovery by age.
Key rules
Full replacement cost on the dwelling requires Coverage A of at least 80% of RC
The test is applied at the time of loss against the dwelling's full replacement cost. Below 80%, the insured gets the greater of ACV or the pro-rata replacement-cost figure.
Why the exam cares: The 80% threshold and the greater-of penalty formula are core calculation questions on every personal lines exam.
Replacement-cost hold-back: depreciation is released only after actual repair
On partial losses the insurer pays ACV up front and the balance when repair or replacement is completed; failing to rebuild leaves the insured at ACV even at a total loss under hold-back mechanics.
Why the exam cares: Scenario questions test what the insured collects before versus after completing repairs.
Unendorsed contents settle at ACV; HO 04 90 upgrades them to replacement cost
HO 04 90 removes the depreciation deduction on personal property, subject to an age-of-property exception. HO 23 84 grants replacement cost but keeps antiques, fine arts, and similar personal effects at ACV.
Why the exam cares: Matching the valuation endorsement to its effect — and knowing what stays at ACV — is a repeat exam pattern.
Inflation guard raises limits continuously and pro rata through the term
Under HO 04 11 the applicable limit on any date equals the inception limit times one plus the annual rate times the fraction of the term elapsed — e.g., $300,000 at 6% is $309,000 six months in.
Why the exam cares: The pro-rata mid-term computation is a named calculation question; candidates who apply the full annual rate get it wrong.
HO 04 52 offers Locked-in (fixed limit) versus Floating (limit tracks RC to a cap)
Locked-in fixes Coverage A at the declarations amount regardless of construction-cost movement; Floating lets the limit follow replacement-cost changes during the term up to a stated percentage cap.
Why the exam cares: The two elections produce very different total-loss outcomes in inflationary periods, and the exam tests which election does what.
Numbers to memorize
- 80% — minimum ratio of Coverage A to dwelling replacement cost for full RC settlement on buildings
- $300,000 × (1 + 0.06 × 6/12) = $309,000 — inflation guard worked example: 6% annual rate, loss at 6 months
- 5 of 6 forms settle contents at ACV unendorsed — HO 04 90 converts personal property to replacement cost
Common traps
- Confusing the 80% requirement with a policy-writing minimum — remember it is measured against replacement cost AT THE TIME OF LOSS, so construction inflation can silently push an insured below 80%.
- Confusing the underinsurance penalty with pure pro-rata — remember the insured recovers the GREATER of ACV or the pro-rata replacement-cost amount, never less than ACV.
- Confusing HO 04 90 with HO 04 06 — remember HO 04 90 changes contents VALUATION to replacement cost, while HO 04 06 changes contents PERILS to open peril.
- Confusing inflation guard mechanics — remember the annual percentage accrues pro rata across the term, so a mid-term loss gets only the elapsed fraction of the annual increase.
For any settlement question, first classify the property (building vs contents), then check the 80% test, then ask whether repair is complete — that three-step order resolves nearly every valuation item.
