The exact mechanics carriers use to value your claim—and why their numbers are often $15,000–$75,000 short of what you're owed.

Settlement calculation is not magic. It follows a formula. Understanding that formula—and where carriers manipulate it—puts you in position to recover what you're entitled to.
Every property insurance settlement follows the same basic structure. The carrier calculates a gross loss, then applies deductions. The formula:
Gross Loss (Scope × Unit Prices) − Deductible − Depreciation (if ACV) = Net Settlement
Use our insurance settlement calculator to estimate your claim value and identify potential gaps.
The gross loss is capped by your policy limits. If the calculated loss exceeds your dwelling or contents limits, you receive the limit amount minus deductible and depreciation.
Where carriers reduce payouts: in scope (omitting items), in pricing (using below-market rates), in quantities (undercounting square footage, linear feet, units), and in depreciation (applying excessive wear-and-tear deductions). Each of these is controllable—and disputable.
Scope is the list of damaged items and repairs required. It drives the entire calculation. If the carrier omits an item from scope, that item generates $0 in the estimate—even if it is clearly damaged and covered.
Carriers systematically reduce scope through:
Water damage behind walls, roofing decking, insulation, and structural elements are routinely omitted. The carrier's position: "We didn't see it." Your documentation—photos of removal, moisture readings, contractor observations—creates the record that supports scope inclusion.
Once scope is set, each line item is priced. Labor and material rates come from carrier databases—typically proprietary or outdated versions of industry software.
Most carriers use Xactimate or similar platforms. The software is the same; the configuration is not. Carriers set labor rates, material costs, and regional modifiers. These are often 15–30% below current market.
Contractor estimates reflect market rates. A line-by-line comparison between carrier and contractor estimates reveals pricing gaps. Those gaps are recoverable.
Even when line items exist, quantities are often wrong. Square footage of flooring, linear feet of gutters, number of outlets, square footage of roofing—all can be undercounted. A 2,200 sq ft roof billed as 1,800 sq ft loses 400 sq ft of payment. At $4/sq ft, that's $1,600. Multiply across dozens of line items and undercounts add up to $5,000–$20,000. Verify every quantity against your contractor's estimate and actual measurements.
Your deductible is subtracted once per claim, typically from the building loss first. A $2,500 deductible on a $35,000 dwelling loss yields $32,500.
With ACV (actual cash value), the carrier pays replacement cost minus depreciation. A 10-year-old roof with a 25-year life may get 40% depreciation—so a $20,000 replacement becomes $12,000 paid.
With RCV (replacement cost value), you receive ACV upfront and recover depreciation after repairs are complete. The carrier holds back the depreciation amount until you submit proof of repair. Many carriers delay or underpay.
Depreciation schedules vary by carrier. Excessive depreciation—beyond reasonable useful life—can be disputed with evidence of condition and market data.
Your dwelling and contents limits cap recovery. A $250,000 dwelling limit means the carrier will not pay more than $250,000 for structure damage, regardless of calculated loss. Under-insured losses are a separate problem; within limits, scope and pricing disputes determine your payout.
Depreciation reduces the value of aged property. A 15-year-old HVAC system might receive 60% depreciation—so a $6,000 replacement is paid at $2,400 under ACV. Carriers use internal schedules: roof 20–25 years, HVAC 10–15, flooring 15–25. These schedules are not fixed; you can dispute excessive depreciation with evidence of condition, maintenance records, and manufacturer data. RCV policyholders recover the withheld amount after repairs—but must submit invoices and request payment.
These items are routinely excluded from initial estimates. Document them; dispute their omission.
Do not wait for the carrier to include these items. Obtain contractor estimates that explicitly list O&P, decking, permits, and code upgrades. Submit them with your initial proof of loss or first supplement. Carriers are more likely to pay when the omission is documented upfront rather than discovered later.
Roof and storm claims often follow this pattern of scope and pricing gaps.
Storm, hurricane, and tornado claims often involve multi-trade scope and O&P disputes.
State law affects how carriers calculate and pay claims. Timelines for payment, bad faith standards, and appraisal rights vary. Regional labor and material costs also vary—carriers use different regional modifiers.

When the carrier's calculation is wrong, escalate systematically:
Carriers use proprietary software (often Xactimate or similar) to build scope and pricing. The formula: scope (what's damaged) × unit prices (labor, materials) − deductible − depreciation (if ACV) = settlement. Scope and pricing are where carriers systematically reduce payouts.
Insurance estimates exclude scope items, use below-market labor rates, undercount quantities, and apply heavy depreciation. Contractor estimates reflect full repair cost at market rates. Gaps of $15,000-$50,000 are typical—and recoverable with proper documentation and supplementation.
Xactimate is estimating software carriers and contractors use. Carriers configure it with their own pricing, which often lags market rates by 15-30%. Line-item disputes and quantity adjustments in Xactimate can recover thousands. See our Xactimate estimate review guide for dispute strategies.
ACV (actual cash value) policies pay replacement cost minus depreciation. A 10-year-old roof might have 40-50% depreciation applied. On a $20,000 roof, that's $8,000-$10,000 withheld. RCV policies hold depreciation until repairs are complete; you recover it after work is done. Excessive depreciation can be disputed.
Overhead and profit (O&P) covers a general contractor's supervision and profit when multiple trades are required. Carriers often omit it to reduce payouts. If your repair requires roofing, framing, electrical, and drywall, O&P is typically owed—often $4,000-$8,000 or more. See our overhead and profit dispute guide.
Yes. Submit a supplement with line-by-line comparison, contractor estimates, and supporting documentation. Dispute missing scope, underpriced items, excessive depreciation, and omitted O&P. Most policyholders recover $10,000-$40,000 through supplementation.
Your deductible is subtracted from the gross settlement. A $2,500 deductible on a $30,000 claim yields $27,500. Deductibles are applied per claim, not per line item. You cannot dispute the deductible itself if it's clearly stated in your policy.
Settlement cannot exceed your policy limits. If your dwelling limit is $300,000 and the repair cost is $350,000, you receive $300,000 (minus deductible). Policy limits cap recovery; scope and pricing disputes apply within those limits.
With RCV coverage, the carrier pays ACV first and holds back depreciation. After you complete repairs and submit invoices, you receive the withheld depreciation. Many carriers delay or deny this payment. See recoverable depreciation not paid for recourse.
Yes. Each carrier uses different software configurations, labor rate databases, and internal guidelines. State Farm, Allstate, Farmers, USAA, and others each have distinct practices.
