How this TDEE Calculator works
The TDEE Calculator estimates your total daily energy expenditure by combining your basal metabolic rate with an activity multiplier. Enter weight (kg), height (cm), and age to estimate bmr, tdee, and cutting calories. The calculator updates instantly and adds a comparison table plus chart so you can test the sensitivity of the result before you use it in a decision.

Inputs
- Body weight in kilograms.
- Height in centimeters.
- Age in years.
- 1.2=sedentary, 1.375=light, 1.55=moderate, 1.725=active, 1.9=very active.
Outputs
- Basal metabolic rate (calories/day).
- Total daily energy expenditure.
- TDEE minus 500 for weight loss.
Assumptions
- Uses the Mifflin-St Jeor equation for males.
- Activity multiplier is a self-assessed estimate.
Tips
- Track actual intake for 2 weeks to calibrate.
- Adjust by 200-300 calories if weight isn't changing as expected.

Example
Active adult estimate
Inputs
- Example input Weight (kg): 80
- Example input Height (cm): 180
- Example input Age: 28
- Example input Activity multiplier: 1.55
Outputs
- Example result BMR: 1,790
- Example result TDEE: 2,774.5
- Example result Cutting calories: 2,274.5
Moderate activity (3-5 days of exercise) uses a 1.55 multiplier.
TDEE by activity level
| Activity multiplier | TDEE | Cutting calories |
|---|---|---|
| 1.2 | 2,038.5 | 1,538.5 |
| 1.38 | 2,335.78 | 1,835.78 |
| 1.55 | 2,633.06 | 2,133.06 |
| 1.73 | 2,930.34 | 2,430.34 |
| 1.9 | 3,227.63 | 2,727.63 |
