ProjectFigure builds free, fast calculators for home and DIY projects — turning your measurements into the exact quantities you need to buy.
Every project starts with the same question: how much do I actually need? Order too little concrete and you get a cold joint; buy too much tile and you have eaten your budget. ProjectFigure exists to answer that question precisely, for free, in a few seconds.
Each calculator shows its method and assumptions in plain language, applies a sensible waste allowance, and tells you when a job is better handed to a licensed professional. We would rather show our working than ask you to trust a black box.
We are an independent project based in Australia, building for a worldwide audience. The calculators run entirely in your browser — nothing you type is sent to us.
ProjectFigure is free to use and supported by advertising and affiliate links. When a calculator works out what you need, it can show a matching shopping list; if you buy through those links we may earn a small commission at no extra cost to you. We only suggest products that match your result. See our disclosure for the details.
