What we do
Calculatte is an independent website of free calculators and short guides for everyday questions about dates, money, health and the kitchen. The goal is simple: give a clear answer, show how it was worked out, and stay out of your way.
How we make it
Every calculator runs in your browser, so the numbers you type are not sent anywhere. Each page explains its formula and includes a worked example you can check by hand. We use AI tools to help draft explanations and guides, and every formula is tested against worked examples. Where a rule comes from an official source, such as Social Security retirement ages, we say so and point to that source. Read more in our editorial policy.
Who is behind it
Calculatte is run by an independent publisher. If you have a question, spot a mistake or want a calculator added, please get in touch. We read every message.
How the site is funded
Calculatte is free to use. We may show advertising, which pays for the domain and the time spent building the site. Ads never influence the results our calculators give.
