About GoBuildCalcs
GoBuildCalcs is a free online toolkit of trade, construction, electrical, and building calculators. Whether you are sizing wire, estimating concrete, or planning a deck, our tools help you get reliable numbers quickly — right in your browser, with no account required.
Why GoBuildCalcs Exists
On every job site, someone needs a fast answer: How many bags of concrete? What wire gauge? How much lumber? Too often, those calculations mean digging through spreadsheets, outdated reference charts, or guesswork.
GoBuildCalcs was built to remove that friction. We turn common trade math into simple, focused tools you can use on a phone in the field or at a desk during estimating. Less time calculating, more time building.
Who We Help
GoBuildCalcs is for anyone who works with building materials and trade math:
- Tradespeople — electricians, carpenters, masons, roofers, and other pros who need quick field calculations
- Builders & contractors — teams planning jobs, ordering materials, and checking quantities before purchase
- DIYers & homeowners — people tackling projects who want clear numbers before they buy supplies
- Estimators & project planners — anyone preparing takeoffs, budgets, or material lists with confidence
You do not need special software or training. Enter your measurements, get your results, and move on.
Our Mission
Our mission is to provide fast, accurate calculators for every trade — tools that are easy to use, grounded in real-world formulas, and built for the way people actually work.
Every calculator on GoBuildCalcs is designed with a single goal: give you a trustworthy answer in seconds, so you can make better decisions on the job.
Our Vision
GoBuildCalcs is just getting started. We plan to expand with more calculators, cover more trades, and improve accuracy over time — adding new tools based on what builders and tradespeople actually need.
Our long-term vision is a comprehensive, go-to resource for construction and trade calculations: one place where pros and DIYers alike can find the right tool for the job, backed by clear explanations and sensible defaults.
Built by Franck
GoBuildCalcs was created by Franck, a developer with a passion for practical tools that solve real problems on the job site. The project started from a simple idea: trade math should be accessible to everyone, not buried in complicated software or scattered reference materials.
