What we do
Most calculator websites give you a number and nothing else. We take a different approach: every Calculate.Studio calculator shows the underlying formula, explains each variable, provides a worked example, and lists the standards or references the method is based on. The goal is that you can trust the result because you can see exactly how it was produced.
All calculations run in your browser and return instantly. There is no signup, the tools are free, and they work in metric or imperial units and in 15 languages.
How we are funded
Calculate.Studio is free to use. We intend to support the site through unobtrusive advertising and our free embeddable-widget program. We never charge for access to a calculator, and we never sell user data — because, by design, we do not collect it (see our Privacy page).
Who writes and reviews the calculators
Calculators and supporting articles are produced and reviewed by the Calculate.Studio editorial team, working from published standards and primary sources. Every formula is checked against its published reference and covered by an automated test before it goes live. For the standards we work to and how we handle corrections, see our Editorial Policy and Calculation Methodology.
