About FitCalcLab

FitCalcLab is a collection of simple fitness calculators designed to help people estimate useful numbers such as BMI, BMR, TDEE, macros, protein intake, water intake, body fat percentage and training estimates.

Our goal

The goal of FitCalcLab is to make fitness numbers easier to understand. Instead of complicated spreadsheets or unclear formulas, each calculator is built to be fast, clean and easy to use on both desktop and mobile devices.

Privacy-friendly by design

FitCalcLab does not require an account to use its calculators. Some preferences and calculator values may be saved locally in the browser to make the tools easier to use, but this information stays on the user's device.

Informational estimates

The calculators provide estimates for educational and informational purposes. Fitness and nutrition needs can vary from person to person, so results should be used as a starting point, not as medical advice.
