About CostTo.Build

CostTo.Build is a free home improvement cost calculator site for homeowners, contractors, real estate investors, and anyone planning a renovation. Every tool runs entirely in your browser, requires no signup, and returns a low/average/high price range in under a second — so you can budget before you pick up the phone to a contractor.

Why This Site Exists

Most homeowners go into renovation projects blind. The first quote looks reasonable, the second is twice as high, and by the time the third arrives you have no idea which one is fair. Contractor pricing guides are gated behind newsletter signups. Cost articles are written for SEO traffic, not for someone trying to decide whether to redo their bathroom this year. We built CostTo.Build to just answer the question: how much should this actually cost in 2026?

Who Maintains This

CostTo.Build is maintained by the CostTo.Build Editorial Team— an editorial group that builds and reviews each calculator's cost model against published industry pricing and government wage data. We focus on getting the inputs that actually move a project's price right: which line items contractors add, where the published "average" diverges from a real quote, and how costs shift by region.

We're not a brokerage, an aggregator, or a lead-generation business. We don't take a cut of any contractor referral, and we don't pay-for-placement on any of the links you'll see. The site is funded by display advertising, fully disclosed in our disclaimer.

How We Calculate Cost

Every calculator estimates two things and adds the standard fees that come with the job:

  1. Material cost — a per-unit price (per sq ft, per linear foot, per fixture or unit) drawn from published retail and industry cost data, multiplied by your project size.
  2. Labor cost — a per-unit or per-job labor figure for the trade, scaled to your project. Where permits, disposal, or similar fees are a standard part of the job, we fold them in.

We then adjust labor (and, to a smaller degree, materials) for your state using an index derived from U.S. Bureau of Labor Statistics construction wage data — a state-level approximation, not a ZIP-precise figure. We do notadd general-contractor overhead and markup, so a managed, turnkey job can run higher than the estimate. The full method, with what's included and excluded, is on our methodology page.

The result is presented as a range — low, average, and high — because single-number estimates are misleading. A bathroom remodel might run $8,000 in one metro and $24,000 in another for the same scope; presenting a range forces both us and you to think about which end your situation lands on.

Our Data Sources

We don't invent numbers. Each calculator's cost model is built from, and cross-checked against, published sources, and the relevant ones are listed on every calculator page. They include:

  • U.S. Bureau of Labor Statistics (BLS) — wage statistics for construction and related trades, used to build the state-level regional index.
  • National retailers— material price reference from home-improvement retailers such as Home Depot and Lowe's.
  • Industry cost references — Fixr, HomeAdvisor, and Angi for benchmark project ranges.
  • Building codes & standards — IRC, EPA, and similar requirements for sizing calculations (e.g., septic tank sizing, egress dimensions).

We review pricing periodically — the current data was last reviewed June 2026. If you spot something that doesn't match what you're seeing in your market, please tell us (contact below). We'd rather be corrected than stale.

What This Site Is Not

Three things you won't get from CostTo.Build:

  • Not a quote. A real contractor needs to visit the site to give a real price. Our estimates are starting points for comparison, not commitments.
  • Not a lead-gen funnel.We don't collect or sell your information. The calculators run in your browser; your project inputs aren't sent to our servers.
  • Not professional advice. For structural changes, permits, or anything safety-critical, hire a licensed pro. Our tools help you go into that conversation informed.

Privacy

The calculators run entirely in your browser — your project inputs aren't sent to our servers. We use Google Analytics to understand which calculators get used and which confuse people. See our privacy policy for full detail.
