US home improvement cost research

Know what your home project should cost.

Cost guides, interactive calculators, and maintenance research for homeowners — built from public data and a methodology we publish in full, not guesswork.

Methodology

How our cost estimates work

Every figure on this site traces back to a published, repeatable method.

01

Start from public data

Labor and materials indices from the BLS, Census, and other government sources — never invented numbers.

02

Apply regional adjustment

Costs are adjusted for regional labor rates and cost-of-living differences across US states and metros.

03

Run the estimation engine

Base cost, labor, materials, complexity, and inflation are combined into a documented calculation.

04

Publish a disclosed range

We show a range, not a false-precision quote — and link the sources and assumptions behind it.

Why trust this data

Independent research, published methodology.

HomeCostGuide isn't a contractor marketplace or a lead-gen funnel dressed up as content. We publish how every estimate is calculated, where the underlying data comes from, and when it was last updated — so you can judge the number, not just read it.
