About Estimatool
Fast, free tools — built with a point of view.
Estimatoolis a small, independent collection of estimate calculators for home projects — flooring, roofing, HVAC sizing, and more to come. It's for homeowners, DIYers, and contractors who want a real number before they walk into a store or get on the phone with a quote. Every tool is free, runs in your browser, and gets straight to the point.
Why it exists
Most “calculator” sites are slow, buried in ads, and gated behind email walls — and half of them give you a single number with no context. We wanted the opposite: tools that load fast, explain their assumptions, and respect your time and your privacy. The site is funded by ads, but the tools come first.

How we think about accuracy
Every calculator here produces an estimate — material counts, cost ranges, BTU loads. We are deliberate about labeling them as estimates, showing honest low-to-high ranges instead of false precision, and documenting the formulas and assumptions behind them right on the page. The goal is to help you plan and sanity-check a quote, not to replace one. For the work itself, confirm with a contractor and a firm bid.
