TDEE Calculator

Calculate your Total Daily Energy Expenditure and personalised macros for your fitness goal — cut, maintain, or bulk.

Quick Answer & Summary

A TDEE Calculator determines your Total Daily Energy Expenditure and Basal Metabolic Rate (BMR) based on age, gender, height, weight, and activity level using the Mifflin-St Jeor equation.

Mifflin-St Jeor BMR Formula
BMR (Men) = 10W + 6.25H - 5A + 5 | BMR (Women) = 10W + 6.25H - 5A - 161 (TDEE = BMR * Activity_Factor)

Where W = Weight in kg, H = Height in cm, A = Age in years.

How to Use TDEE Calculator

1

Enter your stats

Input your weight, height, age, gender, and activity level. Supports both metric and imperial.

2

Calculate

Get your BMR (calories at rest) and TDEE (calories needed to maintain weight).

3

Pick your goal

View calorie and macro targets for cutting, maintaining, or bulking.

Pro Tips
TDEE is more accurate than BMR for planning daily intake
Protein goal is set at 2g per kg of bodyweight for muscle preservation
Results are estimates — track progress and adjust every 2–4 weeks
