The Starting Point: What Was Actually Lost?
Before any math happens, an insurer needs to establish what was damaged or lost and confirm it falls within your covered perils. An adjuster — either employed by the insurer or contracted independently — inspects the damage, reviews documentation, and produces a scope of loss. This scope becomes the foundation for every calculation that follows.
If you've ever wondered what happens between filing a claim and receiving an offer, the claims process walkthrough explains each stage in detail. The settlement calculation doesn't begin until the scope of loss is agreed upon, which is why thorough documentation on your end — photos, receipts, serial numbers — matters from day one.

Average depreciation on a 10-year-old roof
Depreciation rates for roofing commonly range from 2–5% per year depending on material type, per standard insurer schedules.
$2,000–$3,000
Most common homeowners deductible range
Industry data from the Insurance Information Institute indicates most homeowners carry deductibles in this range, directly reducing net claim payments.

Gap between ACV and replacement cost payouts
On older property, the difference between an ACV settlement and a full replacement cost settlement can be substantial, particularly for roofing and appliances.
ACV vs. Replacement Cost: The Core of the Calculation
The single biggest factor in any settlement figure is which valuation method your policy uses. This isn't a decision the insurer makes after the fact — it's defined in your policy language before any loss occurs.
- Actual Cash Value (ACV): The insurer estimates what your property was worth at the moment of loss — essentially, replacement cost minus depreciation. A five-year-old laptop doesn't get replaced at today's full retail price; it gets valued at what a five-year-old laptop in similar condition would fetch.
- Replacement Cost Value (RCV): The insurer calculates what it would cost to replace the damaged property with a comparable new item at current prices. Many RCV policies pay ACV up front, then release the remaining "recoverable depreciation" once you provide proof of replacement.

Request a Written Valuation Breakdown
You have the right to ask your insurer for a line-by-line explanation of how your settlement figure was calculated. This includes the replacement cost estimate, the depreciation schedule applied, and the deductible subtracted. Reviewing this document carefully is the most direct way to identify figures you can support challenging with documentation.
Depreciation Schedules and How They're Applied
Depreciation is calculated using schedules that assign an annual value-loss rate to categories of property. Roofing materials, for example, may depreciate over 20 years; consumer electronics may lose value much faster. The insurer multiplies the item's replacement cost by the applicable depreciation rate and the item's age to arrive at a deduction.
These schedules are generally standardized within a company and are subject to state insurance regulations, but they can vary. If you feel the depreciation applied to your claim is excessive or uses an incorrect age for your property, you can — and should — ask for the schedule and challenge specific line items with documentation.
Deductibles, Policy Limits, and Final Math
Once the gross value of your loss is established, two more numbers come into play before you see a check.
- Deductible: This is subtracted first. If your roof sustains $12,000 in damage and your deductible is $2,000, the insurer's base payment is $10,000.
- Policy limits: No payment can exceed the coverage limit stated in your policy, regardless of the actual loss. If your personal property limit is $30,000 and your documented loss is $45,000, the most the insurer will pay is $30,000.
Understanding these caps before a loss occurs is part of making sure your coverage actually fits your needs. If you're navigating your first claim and want a full walkthrough, the first insurance claim guide covers each step from documentation to final payment.
“Policyholders who understand how their insurer values a loss are far better positioned to have a productive conversation about the settlement — and to identify when a figure deserves a second look.”
