How the calculator depreciates
Each line uses straight-line depreciation (age ÷ expected life), capped at the maximum you choose. Real estimates may adjust for condition, use different life tables or leave some items such as permits undepreciated. Treat the output as a planning figure, not a payment promise.
Life expectancies often seen in estimates
| Item | Common range |
|---|---|
| Laminated asphalt shingles | 25–30 years |
| Steel roofing panels | 40–50 years |
| Interior paint | 8–12 years |
| Carpet and pad | 8–12 years |
| Vinyl siding | 30–40 years |
| Gas furnace | 15–20 years |
Collecting the holdback
Most replacement-cost policies release recoverable depreciation once repairs are complete, often within a set number of days. Send final invoices and photos of finished work. The claim timeline planner can remind you before your window closes.
Questions about this calculator
Should labor be depreciated?
Approaches differ by insurer, policy wording and court decisions. Ask your insurer to explain in writing whether and how labor was depreciated in your estimate.
What happens if I don’t repair?
Under most replacement-cost policies you keep the actual cash value payment but give up the depreciation that was held back.
Can depreciation itself be appraised?
Often yes, since depreciation is part of the value of a loss. Policy language and the facts of the claim control.
