Replacement Cost Meets the 80% Rule
The Riveras insure a 2,200 sq ft home for $400,000 on a replacement-cost homeowner policy. Their agent's replacement-cost estimator, run at policy inception two years ago, put full replacement cost at $500,000, but the Riveras chose the $400,000 limit to lower premium. Construction costs in their region have risen 12% since then, so current replacement cost is now about $560,000. A kitchen fire causes $120,000 in damage. The policy contains a standard replacement-cost provision requiring insurance to at least 80% of full replacement cost to collect full replacement cost on a partial loss; otherwise settlement is limited to the greater of actual cash value or (limit ÷ required amount) × loss. The policy also has a $2,000 deductible.
1. Compute the required insurance-to-value amount and determine whether the Riveras face a coinsurance penalty on the $120,000 kitchen loss.

Step 1 - Required amount: 80% × current replacement cost. Using the current $560,000 figure, required = 0.80 × $560,000 = $448,000.
Step 2 - Compare to carried limit: The Riveras carry $400,000, which is below the $448,000 required. They are underinsured and the coinsurance/replacement-cost penalty applies.
Step 3 - Penalty formula: Payment = (limit ÷ required) × loss = ($400,000 ÷ $448,000) × $120,000 = 0.8929 × $120,000 ≈ $107,143 (replacement-cost basis).
Step 4 - Deductible: Subtract $2,000 → approximately $105,143 payable on a replacement-cost basis.
The critical trap: the required amount is measured against current replacement cost ($560,000), not the $500,000 estimator figure from two years ago. Rising construction costs pushed the 80% threshold above the Riveras' limit even though they were arguably close at inception. Had they carried $448,000+, they would have collected the full $120,000 less deductible.
2. The insurer offers to settle at actual cash value first. Explain how ACV settlement interacts with the replacement-cost provision and what the Riveras must do to capture the replacement-cost difference.
Read the worked answer
Replacement-cost policies commonly pay actual cash value first (replacement cost minus depreciation) and hold back the replacement-cost difference until the insured actually repairs or replaces the damaged property. So the initial check reflects depreciated value of the kitchen - say the $120,000 loss has $30,000 of depreciation, giving an ACV of $90,000, then the coinsurance formula and deductible are applied to that figure.
To capture the withheld depreciation, the Riveras must (1) complete the repair/replacement, and (2) submit proof - typically within a stated window (commonly 180 days, per policy terms). Only then does the insurer release the recoverable depreciation, still subject to the coinsurance penalty above.
The judgment point: the coinsurance penalty and the ACV-first mechanism compound. The Riveras lose money twice - once to underinsurance and once to the holdback timing - unless they repair promptly and document it. The durable fix is to raise the limit to at least $448,000 (ideally to the full $560,000) and to re-run the estimator annually, since the 80% test moves with construction costs.
