The method used
This planner applies straight-line depreciation — age divided by expected life — capped at the maximum you choose. Real estimates may adjust for condition, use different life expectancies or treat some items as non-depreciable, so treat the result as a planning figure.
Common life expectancies
| Item | Typical range |
|---|---|
| Three-tab shingles | 18–25 years |
| Laminated shingles | 25–30 years |
| Vinyl siding | 30–40 years |
| Interior paint | 8–12 years |
| Carpet | 8–12 years |
| Furnace | 15–20 years |
Getting the holdback paid
Most policies release recoverable depreciation once repairs are finished within a set time. Send invoices and photos of the completed work, and use the deadline calendar so the window doesn’t close on you.
Questions about this tool
Can labor be depreciated in Illinois?
Practices and court decisions on labor depreciation vary. Check whether your estimate depreciates labor and ask the carrier to explain its approach in writing, or ask an attorney.
What if I don’t make repairs?
Under most replacement-cost policies, you keep the ACV payment but may not collect the held-back depreciation.
