← 所有工具TDEE Calculator
Calculate your Total Daily Energy Expenditure (TDEE) based on your activity level.
Your BMR tells you what you burn at rest, but your TDEE (Total Daily Energy Expenditure) tells you what you burn in the real world. By accounting for your daily movement—from walking to the fridge to an intense gym session—your TDEE represents the 'Maintenance Calories' you need to keep your current weight. Whether you want to lose fat, build muscle, or maintain your progress, your TDEE is the most important number in your fitness arsenal. Our TDEE Calculator provides a precise estimate of your daily burn, helping you set calorie targets that actually work.
工作原理
The tool first calculates your BMR and then applies an 'Activity Multiplier' (known as a Katch-McArdle or Harris-Benedict multiplier) to account for the thermic effect of your daily movement and exercise.
计算公式
TDEE = BMR × Activity Multiplier
Calculation Examples
1. **Active**: A woman with a 1,400 BMR who is 'Moderately Active' (x1.55) has a TDEE of **2,170 kcal/day**.
Why use this tool in your daily life?
Your TDEE is the master key to weight management. By understanding how your physical activity level influences your caloric needs, you can make informed decisions about your exercise routine and food choices to reach your goals faster.
