About TDEECalculator

TDEECalculator.it is a free tool that helps you find out how many calories your body burns each day. We call this your Total Daily Energy Expenditure, or TDEE.

Our Mission

We want to make calorie tracking simple and accessible for everyone. Our calculators use proven scientific formulas to give you a clear picture of your daily energy needs. Whether you want to lose weight, build muscle, or maintain your current shape, knowing your TDEE is the first step.

The Science Behind Our Calculators

We use three well-known formulas to estimate your calorie needs:

Mifflin-St Jeor — The most widely recommended formula for estimating basal metabolic rate (BMR). It uses your age, weight, height, and gender.
Harris-Benedict — One of the oldest and most cited BMR equations, updated in 1984 for better accuracy.
Katch-McArdle — Best for people who know their body fat percentage. It uses lean body mass for a more precise result.

Your BMR is then multiplied by an activity factor to estimate your total daily calorie burn.

Who Is This For?

Our tools are designed for anyone who wants to understand their body better. Athletes, dieters, fitness beginners, and health-conscious people all benefit from knowing their TDEE. We offer specialised calculators for women, men, teens, pregnancy, breastfeeding, and specific goals like keto or bodybuilding.
