Separate value, deductible and payment
A replacement-cost estimate is not necessarily the amount of a check. Separate the cost of replacing the damaged item, depreciation, the deductible and any policy limit before comparing an estimate with a payment.
The Texas Department of Insurance example makes this distinction: a $10,000 replacement roof has an illustrated actual cash value of $7,000 at ten years old. With its $4,000 deductible, the illustrated payment is $3,000, not $7,000. Those values illustrate coverage differences; they are not a universal roof depreciation schedule.
A worked example you can change
Our starting scenario uses a $28,000 replacement estimate, an age of ten years, an illustrative 25-year useful life and a $2,500 deductible. Straight-line depreciation is 10 ÷ 25, or 40%: $11,200. That leaves a modeled actual cash value of $16,800 and an initial payment estimate of $14,300 after the deductible.
Under the replacement-cost scenario, the tool shows up to $11,200 of additional payment and a $25,500 total. This assumes eligible repairs support the full replacement estimate. Change the coverage selector to ACV and the additional amount becomes zero; the modeled gap between replacement cost and payment becomes $13,700. The difference is an assumption comparison, not a determination of coverage.
Try increasing the deductible to $18,000. The initial estimate becomes zero, but the replacement-cost scenario can still show a potential $10,000 total after eligible repairs. A zero initial check does not establish that a replacement-cost claim has no further value. Conversely, this tool cannot establish that the insurer owes the additional amount.
Before relying on recoverable depreciation
A replacement-cost policy may make additional payment conditional on completed repairs and documentation. Ask for the deadline, eligible-cost rules and required proof. DIY work or spending less does not automatically forfeit every dollar of depreciation; the settlement depends on the policy and accepted expenses. The Texas home insurance guide explains repair documentation and withheld payments.
- Get the itemized estimate, including quantities, age, condition and depreciation.
- Confirm whether the damaged item has ACV or replacement-cost coverage.
- Ask which expenses, receipts and completion evidence support an additional payment.
- Record the repair deadline and any extension in writing.
- Keep the initial payment separate from the potential remaining amount in your repair budget.
What this calculator leaves out
The straight-line model does not reproduce an insurer’s depreciation method. Presets are editable illustrations, not verified lifespans. It does not model exclusions, coverage limits, taxes, labor-depreciation rules, code upgrades, actual repair spending or multiple-loss deductible credits. The percentage selector assumes the base is dwelling coverage; confirm your own endorsement before using it.
If the estimate and payment disagree
Compare each input with the adjuster’s written calculation. Ask for the policy provision behind a disputed deduction. Appraisal, if available, can involve costs and a binding amount-of-loss decision; it is not a universal way to resolve coverage disputes. Your state insurance department can explain complaint options.
For a separate comparison of possible premium changes, use the claim scenario tool. Its assumptions are not a forecast and should never delay required notice, emergency mitigation or a claim deadline.
