Depreciation by Category: What Insurers Typically Apply

When an insurer calculates your Actual Cash Value payment, they apply depreciation to each item in the claim using schedules that assign expected useful life and annual rates to different property categories. The result — how much is withheld from your payment — can vary dramatically by item type.

Understanding typical depreciation ranges by category helps you identify when rates are reasonable and when they may be more aggressive than your property's actual condition warrants.

How Do Depreciation Schedules Work?

Depreciation is typically calculated on a straight-line basis:

(Age ÷ Expected Useful Life) × Replacement Cost = Depreciation Amount

If a carpet has a 10-year expected life and is 7 years old, straight-line depreciation would apply 70%. A $4,000 carpet replacement has an ACV of $1,200.

Insurers have internal schedules that vary — the ranges below are representative, not guarantees of what your specific insurer will apply. The rates applied to your claim appear in your line-item estimate.

What Are Typical Depreciation Rates for Roofing?

Asphalt shingle: Expected life 20-30 years. One of the most commonly disputed depreciation categories — a 15-year-old asphalt shingle roof could be deprecated 50-75% depending on the insurer's schedule and assumed remaining life.

Metal roofing: Expected life 40-70 years. Significantly slower depreciation than asphalt. A 15-year-old metal roof is generally deprecated far less than an asphalt roof of the same age.

Clay or concrete tile: Expected life 50+ years. Very slow depreciation rate.

Slate: Expected life 75-150 years. Among the slowest depreciation of any roofing material.

Wood shake: Expected life 20-30 years. Similar to asphalt shingle in depreciation profile.

What Are Typical Rates for Mechanical Systems?

HVAC (heating and cooling): Expected life 15-20 years. A 12-year-old system might be deprecated 60-80% under some schedules — meaning the insurer pays only 20-40% of replacement cost. Well-maintained systems with documented service histories support lower depreciation rates.

Water heaters: Expected life 10-15 years. A water heater more than 10 years old may be deprecated 67-100%. Document installation date carefully.

Electrical systems/wiring: Expected life 30-40 years. Slow depreciation relative to mechanical systems.

Plumbing (copper): Expected life 50+ years. Very slow depreciation.

Plumbing (PVC/CPVC): Expected life 25-40 years.

What Are Typical Rates for Interior Finishes?

Carpet: Expected life 5-10 years. Among the fastest depreciating interior items. A 7-year-old carpet may be deprecated 70-100% under standard schedules — often resulting in minimal ACV payment.

Hardwood flooring: Expected life 25-100 years, depending on species and thickness. Dramatically slower depreciation than carpet. A 20-year-old hardwood floor may be deprecated only 20-40%.

Laminate flooring: Expected life 10-25 years.

Tile flooring: Expected life 20-50 years.

Interior paint: Expected life 5-10 years.

Cabinets and millwork: Expected life 15-30 years.

Drywall/plaster: Expected life 30-70 years. Slow depreciation for structural wall surfaces.

What Are Typical Rates for Personal Property?

Electronics (laptops, computers): Expected life 3-5 years. One of the highest depreciation rates of any category. A 3-year-old laptop may be deprecated 60-100%, resulting in very low ACV on items that still function normally.

Televisions and home electronics: Expected life 5-8 years.

Major appliances (refrigerator, washer/dryer): Expected life 10-15 years.

Small appliances: Expected life 5-10 years.

Furniture (upholstered): Expected life 5-10 years.

Furniture (hardwood): Expected life 15-30+ years.

Clothing: Expected life 1-5 years, varies significantly by type and quality.

Jewelry and fine art: Often not depreciated — valued at current market or appraised value. This is one of the most significant differences between jewelry/art and general personal property.

When Should You Dispute Depreciation Rates?

Depreciation schedules are starting points, not immutable facts. If the rates applied don't reflect your property's actual condition and remaining life, dispute them with documentation:

Purchase or installation records establish actual age — which may be younger than assumed.

Maintenance and service records for mechanical systems support a lower effective depreciation rate than a neglected system of the same age.

Inspection reports or manufacturer warranties showing remaining useful life or good condition.

Pre-loss photos showing the item in good working condition.

An HVAC system that's 12 years old but has been professionally serviced every year may have significantly more remaining useful life than the standard schedule assumes. Your maintenance invoices are the evidence.

Frequently Asked Questions

Do depreciation rates vary between insurers? Yes, significantly. Two insurers can apply different depreciation rates to the same item of the same age under the same policy type. There is no universal standard depreciation schedule — each insurer maintains its own. If your estimate's rates seem aggressive, that's a disputable position, not a fixed outcome.

Is depreciation the same for covered perils vs. excluded perils? Depreciation only applies when the damage is covered. If a loss is excluded, depreciation is moot. For covered losses, depreciation applies to the ACV calculation regardless of which covered peril caused the damage.

Can the insurer depreciate an item I just purchased? Technically yes — even new items have some depreciation applied based on their age from the date of purchase. For items purchased within the prior year, dispute any depreciation with your purchase receipt showing the current price is the replacement cost.

Why do electronics depreciate so much faster than flooring? Expected useful life and technological obsolescence both factor in. Electronics become functionally obsolete faster than structural materials. A 5-year-old laptop may cost the same to replace as a new one, but its ACV reflects its short functional life in the insurer's schedule.

If I have RCV coverage, does the depreciation schedule still matter? Yes — because your initial payment is based on ACV, and the withheld depreciation is what you file to recover after repairs. Knowing the depreciation rates on major items helps you understand how large the second payment will be and plan accordingly.

Depreciation Reference Checklist

• Roofing: asphalt shingles depreciate fastest; metal, tile, and slate depreciate much more slowly
• Mechanical systems: HVAC and water heaters depreciate quickly — document installation dates and maintenance history
• Interior finishes: carpet depreciates very fast; hardwood flooring much more slowly
• Electronics: among the highest depreciation rates of any category — document purchase dates carefully
• Dispute rates that don't reflect actual age, condition, or maintenance history with purchase records, maintenance invoices, and condition documentation
• Under RCV policies, withheld depreciation is recoverable after repairs — file within your deadline
