Make the next step clearer
Project Amounts helps you turn a few measurements into a material plan. Our free tools focus on the questions that come before a supplier visit: how much to buy, how waste affects the order, and what your own material prices add up to.
Our approach
Calculations run in your browser. There is no account to create, no subscription to unlock a result and no live price feed pretending to know your local shop. The formulas, packaging rules and exclusions are explained on each calculator page.
Metric and imperial inputs describe the same project. Printable and downloadable lists include inputs and assumptions so you can check them against an actual layout.
What an estimate can do
It can help you plan and ask better questions. It cannot inspect a site, choose structural dimensions or replace a product installation guide. Always verify quantities, site conditions and requirements with the relevant supplier or professional.
