About Calculator365

What Is Calculator365?

Calculator365 is a free, multilingual collection of browser-based calculators created and operated by MSoft Studio. Our goal is to make useful calculations easy to find, understand, and complete on any modern device.

The website includes calculators for mathematics, finance, health and fitness, and everyday date and time tasks. We also offer Calculator365: All-In-One Calc, our iOS app for calculations on the go.

How Our Calculators Work

Calculator inputs and results are processed locally in your browser. They are not sent to Calculator365 servers. You can learn more about the limited technical and analytics data used to operate and improve the website in our Privacy Policy.

We design each calculator around its stated formula, inputs, assumptions, and intended use. Where appropriate, calculator pages include explanations, formulas, examples, and frequently asked questions so you can understand how a result is produced. We also update calculators when we identify errors or opportunities to make them clearer and easier to use.

Important Limitations

Calculator365 provides general informational and educational tools. Calculated results are estimates and may depend on assumptions, rounded values, or information you provide. Financial and health results should not be used as the sole basis for important decisions and are not a substitute for advice from a qualified professional.

For more information about using the website, please review our Terms of Use.
