About the Founder

BuilderCal was built by a developer and DIY home-improvement enthusiast who wanted faster, clearer material estimates. Each calculator shows the formula and assumptions behind its result so you can review the math. Results are planning estimates; material yields, site conditions, product specifications, and local building requirements can change the amount you should order.
