TDEE calculator
Calculator
The calculator needs JavaScript. The tables below give the same numbers for common cases.
How it is worked out
- BMR = 1,345 kcal (Mifflin-St Jeor).
- TDEE = BMR × activity multiplier = 1,345 × 1.375 = 1,850.
- The activity multipliers are the conventional ones; 500 kcal a day is about 0.5 kg (1 lb) a week using the common 3,500 kcal per pound approximation.
| Inputs | Answer |
|---|---|
| Units: Metric (cm, kg); Sex: Female; Age: 35; Height: 165; Weight: 65; Activity level: Light (exercise 1 to 3 days a week) | Your estimated total daily energy expenditure is about 1,850 calories a day. |
| Units: Metric (cm, kg); Sex: Male; Age: 30; Height: 180; Weight: 85; Activity level: Moderate (3 to 5 days a week) | Your estimated total daily energy expenditure is about 2,837 calories a day. |
| Units: US (inches, pounds); Sex: Female; Age: 50; Height: 64; Weight: 150; Activity level: Sedentary (little or no exercise) | Your estimated total daily energy expenditure is about 1,542 calories a day. |
How to use it
Total daily energy expenditure is the calories you burn in a day including activity. It is estimated as BMR × an activity multiplier: 1.2 sedentary, 1.375 light, 1.55 moderate, 1.725 very active, 1.9 extra active. Eating about your TDEE keeps weight steady.
The table also shows intakes about 500 calories below and above, which correspond to about 0.5 kg (1 lb) a week of loss or gain under the common 3,500 kcal per pound approximation. Real changes vary. This is general information and an estimate, not medical advice; talk to a healthcare professional about your own situation.
Frequently asked questions
What is TDEE?
The calories you burn per day in total, including exercise.
How do I use my TDEE to lose weight?
Eat fewer calories than your TDEE; a modest deficit is easier to keep up.
Which activity level should I choose?
The lower one if unsure; people tend to overestimate how active they are.
