Home Insurance Depreciation (ACV) Calculator

Q: What's the difference between ACV and RCV?

ACV pays replacement cost minus depreciation for age and wear. RCV pays the full cost to replace the item today, with no depreciation deduction.

Q: How is depreciation calculated on a home insurance claim?

Most commonly through straight-line depreciation: age divided by total expected useful life determines the depreciation percentage.

A 10-year-old roof worth $20,000 new might only pay out $9,000 on an actual cash value policy after depreciation and your deductible. See the real gap before a claim, not after.

Two very different numbers for the same claim

When something covered gets damaged, your policy pays out based on one of two methods. Replacement Cost Value (RCV) pays what it actually costs to replace the item today, with no deduction for age or wear. Actual Cash Value (ACV) pays that same replacement cost minus depreciation — the item's value is reduced to reflect how much of its useful life has already been used up.

How depreciation actually gets calculated

The most common approach is straight-line depreciation: divide the item's age by its total expected useful life to get a depreciation percentage, then subtract that percentage of the replacement cost. A 10-year-old asphalt shingle roof with a typical 20-year lifespan is considered 50% depreciated — if it would cost $10,000 to replace today, its actual cash value is $5,000, before any deductible is even applied.

Scenario	RCV payout	ACV payout
10-yr roof, 20-yr life, $20,000 to replace, $1,000 deductible	$19,000	$9,000
15-yr roof, 20-yr life, $15,000 to replace, $1,000 deductible	$14,000	$9,000

Why RCV protects against more than just depreciation

Replacement cost coverage also protects against something people often overlook: construction cost inflation. A roof installed 15 years ago for $12,000 might genuinely cost $20,000 to replace today, purely from rising labor and material costs — RCV pays close to that current $20,000 figure, while ACV would depreciate the ORIGINAL, lower cost even further. In a period of rising construction costs, that gap between "what it cost then" and "what it costs now" can matter as much as depreciation itself.

Watch for roof-specific ACV, even on an otherwise RCV policy

A meaningful and growing number of insurers now apply ACV specifically to roofs once they pass a certain age — commonly around 20 years, sometimes younger in high-risk states — even when the rest of the policy pays replacement cost. This is a genuine coverage gap that many homeowners don't discover until they're filing a claim on an older roof and learn the payout is far less than they expected. Check your policy declarations specifically for roof age thresholds and any "ACV roof endorsement," separate from your general dwelling coverage type.

Recoverable depreciation — the middle ground

Many RCV policies don't pay the full replacement cost upfront. Instead, they pay the ACV amount first, then reimburse the remaining "recoverable depreciation" after you complete the actual repair or replacement and submit proof. This protects the insurer against paying for work that never happens, but it means you may need to cover the depreciation gap out of pocket temporarily, even with full RCV coverage, until the work is finished.

Is ACV ever the right choice?

Some industry voices frame ACV as a legitimate way for homeowners to lower premiums by accepting a form of self-insurance on the depreciated portion of older items — a reasonable tradeoff for someone who could comfortably absorb the gap. The honest question is whether you could actually afford the difference this calculator shows, out of pocket, if a claim happened tomorrow. If not, the premium savings from ACV coverage may not be worth the exposure.

Straight-line depreciation methodology, the recoverable depreciation mechanic, and the roof-specific ACV coverage trend verified across multiple independent 2025-2026 insurance industry sources, with the calculator's formula validated against two independently published worked examples. Actual depreciation schedules vary by insurer, material, and state. This is a planning estimate — review your specific policy's valuation method with your agent.

Frequently asked questions

Before you file a home insurance claim.

What's the difference between ACV and RCV?

Actual Cash Value (ACV) pays the replacement cost minus depreciation for age and wear. Replacement Cost Value (RCV) pays the full cost to replace the item today, with no deduction for depreciation.

How is depreciation calculated on a home insurance claim?

Most commonly through straight-line depreciation: the item's age divided by its total expected useful life determines the depreciation percentage applied to its replacement cost.

Can my roof be covered under ACV even if the rest of my policy is RCV?

Yes - many insurers apply ACV specifically to roofs past a certain age, commonly around 20 years, even when the rest of the policy pays full replacement cost. Check your declarations page for a roof-specific ACV endorsement.

What is recoverable depreciation?

Many RCV policies pay the ACV amount first, then reimburse the remaining depreciation after you complete the actual repair and submit proof - meaning you may need to cover that gap temporarily even with full RCV coverage.

Does replacement cost coverage protect against rising construction costs?

Yes - RCV pays what it costs to replace the item today, which can be significantly more than the original cost due to labor and material inflation since installation, unlike ACV which depreciates a value based on the original cost.
