About Calorie Calculator

Calculate your daily calorie needs (TDEE) based on age, gender, weight, height and activity level.

Calorie Calculator is part of Smart2Office's suite of free browser-based utilities. It is designed to handle everyday tasks that would otherwise require installing dedicated desktop software or subscribing to a paid service. Open the page, use the tool, and close it — there is nothing to set up and nothing to maintain.

It works on any modern device — Windows PC, Mac, iPhone, Android phone or tablet — because it runs entirely in your web browser. That also means there is no version to update, no compatibility issues between operating systems, and no licence to renew.
