About

Project Math helps homeowners plan small projects before they buy.

The site is built for the moment before a store run, quote call, or weekend project, when a homeowner needs a practical material estimate and a clear explanation of the math behind it.

What we publish

Project Math publishes home improvement calculators and short planning guides for paint, flooring, tile, concrete, drywall, landscaping, fencing, decking, and contractor quote checks.

The goal is not to replace product labels, building codes, permit offices, licensed contractors, or professional safety advice. The goal is to make early planning less confusing and reduce obvious overbuying or underbuying mistakes.

How calculators are reviewed

Each calculator shows its formula, uses conservative rounding, and includes a waste buffer because real projects involve cuts, spills, breakage, texture, and measurement mistakes.

Before a calculator is treated as publish-ready, its assumptions should be checked against at least two reliable references, such as manufacturer coverage labels, retailer buying guides, trade guidance, or contractor estimating references.
