MaterialCalc builds free online calculators for real home-improvement and trade projects — concrete, gravel, paint, tile, and more. The goal is simple: give you an accurate number in seconds, and explain how it was worked out so you can trust it.
Calculators that respect your privacy
Every calculator runs entirely in your browser. Your measurements are never uploaded, stored, or sent to a server — the math happens on your device and nothing you type ever leaves it. That also keeps the tools fast and working even on a flaky connection.
Content you can trust
A calculator is only useful if you understand the result. Every tool is paired with a plain-English explanation: the formula, a worked example, sensible defaults (like standard slab thickness or paint coverage), and answers to the questions people actually ask. We show our working, state the assumptions, and date each page so you know it's current.
Results are estimates to help you plan and order materials — always confirm quantities with your supplier before buying.
Who's behind it
MaterialCalc is built by a small, independent team that likes making fiddly calculations effortless. No accounts, no upsells — just tools that do one thing well.
