About

HomeMathCalc is a small collection of free calculators for home improvement and garden projects. We built it because most material calculators online are slow, cluttered, or hide the math. Ours load instantly, work on any phone, and always show the formula.

How the calculators work

Every result is calculated in your browser using standard construction formulas and typical product sizes (for example, an 80 lb bag of concrete mix yields about 0.6 cubic feet). Nothing you type is sent to a server.

Accuracy

Results are estimates. Real quantities depend on the exact product, compaction, surface level and how carefully material is placed. For large orders, confirm with your supplier or contractor before you buy.

Who is behind it

HomeMathCalc is made by Atar Games, an independent studio that builds games and simple, useful web tools.
