Depreciation & Actual Cash Value Calculator
Estimate the depreciation amount and actual cash value (ACV) of an insured item using the straight-line depreciation method commonly used by insurance companies.
Replacement Cost New (RCN) ($)
Current Age of Item (years)
Useful Life of Item (years)
Salvage / Residual Value ($) (optional, default 0)
Maximum Depreciation Cap (%) (optional, e.g. 80)

// Apply depreciation cap const maxDepreciation = rcn * (capPct / 100); const capApplied = totalDepreciation > maxDepreciation; if (capApplied) totalDepreciation = maxDepreciation;
// Depreciation percentage of RCN const depreciationPct = (totalDepreciation / rcn) * 100;
// Actual Cash Value const acv = Math.max(rcn - totalDepreciation, salvage);
// Annual depreciation as % of depreciable base const annualDepPct = ((rcn - salvage) > 0) ? (annualDepRate / rcn) * 100 : 0;

#### Formulas Used
Annual Depreciation ($): Annual Dep = (RCN − Salvage Value) ÷ Useful Life
Total Accumulated Depreciation: Total Dep = Annual Dep × Age (capped at Max Depreciation Cap %)
Actual Cash Value (ACV): ACV = RCN − Total Dep (ACV ≥ Salvage Value)
Annual Depreciation Rate (%): Rate = (Annual Dep ÷ RCN) × 100
#### Assumptions & References
- Straight-Line Method: Depreciation is spread evenly over the item's useful life — the standard approach used by most property & casualty insurers for ACV claims.
- Replacement Cost New (RCN): The cost to replace the item with a new equivalent at today's prices, not the original purchase price.
- Salvage Value: The estimated residual value of the item at the end of its useful life. Defaults to $0 if not specified.
- Depreciation Cap: Many insurers cap total depreciation at 80% of RCN to ensure the ACV never falls below a minimum threshold. Adjust as per your policy terms.
- Useful Life Guidelines: The IRS Publication 946 and industry tables (e.g., Xactimate, Marshall & Swift) provide standard useful-life estimates by item category.
- ACV vs. RCV: ACV policies pay the depreciated value; Replacement Cost Value (RCV) policies pay the full RCN. This calculator computes ACV only.
- Reference: ISO (Insurance Services Office) and NAIC guidelines on property loss settlement and depreciation methodology.
