Insurance ACV / Depreciation + Coinsurance Calculator
Exact property-claim math in your browser: ACV, depreciation, recoverable holdback, and the coinsurance penalty.
See it run - a worked example, 100% in this browser tab
The problem
Property-claim settlements turn on depreciation, the recoverable-depreciation holdback, and coinsurance did/should math that is easy to fumble across age, useful-life, and under-insurance scenarios. A single arithmetic slip can shift an ACV figure or hide a coinsurance penalty an insured never sees coming.
The local-first solution
This Pro plugin runs the standard property-insurance formulas as exact arithmetic entirely in your browser, with each formula citing its convention (ACV, straight-line depreciation, ISO CP 00 90 coinsurance). Nothing is uploaded - no API, no key, no network, no AI - so claim figures and appraised values never leave the device.
What it does
Straight-line depreciation by age vs useful life (annual rate = 1 / useful life)
Optional salvage and a depreciation cap so a functional aged item retains value
Actual Cash Value as RCV minus depreciation
Recoverable-depreciation split: initial ACV payment vs held-back recoverable, with a non-recoverable carve-out
Coinsurance did/should penalty: (limit carried / limit required) x loss, less deductible, capped at the limit
Penalty dollars lost to under-insurance vs a fully-insured claim, with limit-binds and zero-floor handling
Honest scope
This is a calculation aid only - not a coverage determination and not legal, tax, or financial advice; the policy language, endorsements, schedule of values, and applicable state law control the actual settlement. ACV is defined differently in some jurisdictions (fair market value or the broad evidence rule), and useful-life, salvage, condition tables, and the value at time of loss are inputs/appraisals you supply and must confirm against the controlling policy and authority.
Authorities cited
- Actual Cash Value (ACV) = Replacement Cost Value - depreciation (the "replacement cost less depreciation" definition; the most common but NOT universal). ACV is alternatively defined as fair market value or under the "broad evidence rule" in a number of jurisdictions - confirm the controlling state law / policy definition.
- Straight-line depreciation: annual rate = 1 / useful life; depreciation = (RCV - salvage) x min(age / useful life, cap). Useful-life and condition tables are carrier- and line-item-specific (e.g. Verisk/Xactimate depreciation schedules) - reference-data-to-confirm, not encoded here.
- Recoverable depreciation: on a Replacement-Cost (RCV) policy the insurer pays ACV first and releases the withheld recoverable depreciation upon proof of repair/replacement; non-recoverable depreciation is never released - confirm the policy and line-item.
- Coinsurance (standard commercial-property convention, e.g. ISO CP 00 90 - Commercial Property Coinsurance): required limit = coinsurance% x value at time of loss; if the carried limit is less than required, loss payment = (limit carried / limit required) x loss, then less the deductible, capped at the policy limit. Value at time of loss must be appraised.
- This tool encodes the formulas only; figures such as useful life, salvage, condition, ACV definition, and value at time of loss are inputs/appraisals the user supplies and must confirm against the controlling policy and authority.
