What a Water Claim Costs Insurers — and Why That Is Not Your Quote

Two independent bodies publish what homeowners claims actually cost. The figures are real, they are better sourced than anything in the consumer cost guides, and they answer a question most people asking about cost are not asking. This page sets out both, and is careful about the gap.

Both figures read from the publishing bodies' own tables, August 14, 2026.

The two numbers

FigureWhat it measuresSource
$13,954Average claim severity, water damage and freezing Insurance Information Institute, “Average Homeowners Losses, 2018–2022”, sourced to ISO, a Verisk Analytics business
$13,349Average claim severity, all perils, 2024, in 2025 dollars NAIC Center for Insurance Policy and Research, 31 July 2026, from Market Conduct Annual Statement filings covering 715 homeowners companies

The NAIC figure is the more rigorous of the two: mandatory regulatory filing, a regulator with no commercial stake, and a countrywide population of 715 companies. It is not broken out by cause of loss, so it cannot answer a water question directly — the MCAS data call has no peril field at all.

The observation nobody seems to have made

A water claim is an ordinary-sized homeowners claim, not a catastrophic one. III's water-and-freezing severity and NAIC's all-peril severity land within about 5% of each other, from different data pipelines in different years. Water damage is not a distinctive price tag; it is roughly what any homeowners claim costs. It is the frequency that makes water matter to insurers — 1.61 claims per 100 house-years — not the size.

Treat the closeness of the two figures as an observation, not a measurement: they cover different years, different perils and different reporting populations, and only the NAIC figure is inflation-adjusted.

Why neither number is your quote

Read the footnotes, because they are load-bearing

One number you should never see on a page like this

FEMA has stated that the National Flood Insurance Program paid an average claim of more than $66,000 over 2016–2022. That figure is sometimes repeated in water damage articles. It should not be. Flood is a separate peril, excluded from standard homeowners policies — which is precisely why the NFIP exists. It reflects catastrophic inundation of whole structures, usually in a declared disaster. Applied to a failed supply line under a sink it is wrong by an order of magnitude, which is a worse error than the ones this page exists to correct.
