We don't pull prices out of a hat. Every calculator is rebuilt twice a year from published 2026 cost guides, with the source list visible inside each estimate.
Estimates. They reflect typical 2026 prices for a typical project in a given region. Real quotes come from a licensed contractor inspecting your specific site — use our estimate as a sanity check, not a bid.
For well-defined projects (replacing existing materials with industry-standard alternatives), our estimates fall within roughly ±10% of the median of 3 contractor bids — with a typical band of ±8–12%. Larger structural work has more variance.
Even within the same region, contractor pricing varies ±20% based on backlog, crew size, and overhead structure. The low–high range reflects that real-world spread.
No. Everything works without an account. Sign up only if you want to save estimates, share them, or unlock contractor Pro features.
Labor pricing is adjusted by a regional multiplier (0.88 for low-cost regions to 1.45 for major metros). Materials are national averages — they don't vary as much as labor.
Yes. Many do — both for sanity-checking their own estimates and for educating clients. Our Pro tier lets you replace our default rates with your own.
