Replacement Cost vs Actual Cash Value (ACV)

The single most important phrase in a homeowners policy is how it settles a claim: replacement cost or actual cash value. The difference can be thousands of dollars after a loss, and it is often the reason a “cheaper” policy turns out to be the expensive one.

The core difference

  • Replacement Cost Value (RCV): pays what it costs to repair or replace the damaged property with new materials of like kind and quality, no deduction for age or wear.
  • Actual Cash Value (ACV): pays replacement cost minus depreciation — the lost value from age and use.

The same claim, two payouts

A 12-year-old asphalt shingle roof (typical lifespan ~20 years) is destroyed in a storm. New roof cost: $15,000.

Settlement basis Calculation You receive
Replacement cost (RCV) $15,000 − deductible ~$13,000–$14,000
Actual cash value (ACV) $15,000 − ~60% depreciation − deductible ~$5,000–$6,000

On ACV, the depreciation gap — here roughly $9,000 — comes out of your pocket. That gap is the whole reason this choice matters.

The 80% coinsurance rule (the trap)

Most policies require you to insure the home to at least 80% of its full replacement cost to receive full replacement-cost claims — even on partial losses. Fall below 80% and the insurer applies a coinsurance penalty, paying only a proportion of the claim. Example: a home that costs $400,000 to rebuild, insured for only $280,000 (70%), files a $40,000 claim — the insurer may pay roughly (70/80) × $40,000 = $35,000 minus deductible, leaving you to absorb the rest. Insure to replacement cost, not market price — see how much coverage you need.

Which should you choose?

  • Replacement cost is the right default for the dwelling itself — it is what actually rebuilds your home.
  • ACV lowers the premium but shifts depreciation risk to you; it shows up most often on older roofs, where insurers increasingly settle roof claims on ACV. Check your roof’s terms in roof replacement coverage.
  • Extended/guaranteed replacement cost adds a buffer (often 25–50% above the limit) for spikes in construction costs after a widespread disaster.

Frequently Asked Questions

Is replacement cost or actual cash value better?

Replacement cost protects you better because it pays without subtracting depreciation; ACV is cheaper but leaves you covering the depreciated gap.

What is the 80% coinsurance rule?

You must insure your home to at least 80% of its replacement cost to collect full replacement-cost claims; below that, the insurer applies a penalty.

Why did my insurer switch my roof to ACV?

Older roofs are commonly moved to actual cash value to limit the insurer’s exposure to age-related claims — check your declarations page.

Does ACV apply to the whole policy?

It can apply to the dwelling, the roof specifically, or personal property — read each section; they can differ.
