TDEE Formula
The Total Daily Energy Expenditure (TDEE) formula helps you estimate the total number of calories your body burns in a day, crucial for setting effective calorie targets for fat loss. It combines your basal metabolism with your daily physical activity.
Formula
Copy the exact expression or work through it step by step below.
TDEE = BMR x Activity Factor Variables
TDEE
TDEE
The tdee value plugged into the tdee calculation.
BMR
BMR
The bmr value plugged into the tdee calculation.
AF
Activity Factor
The activity factor value plugged into the tdee calculation.
Step By Step
- 1
Set the baseline case with the real calculator inputs.
Gender = Male, Age = 30, Weight Kg = 80, Height Cm = 178
- 2
Translate rates, periods, and cash values onto the same footing before combining them.
Keep the tdee assumptions consistent instead of mixing monthly and annual views.
- 3
Apply the formula and read the first calculator outputs, not just the headline assumption.
The calculator lands with bmr at 1,767.5 and tdee at 2,739.63.
- 4
Run one changed scenario so the formula is stress-tested before it is trusted.
The tdee calculator page is the fastest way to compare that second case.
Worked Example
TDEE sample case
Gender
Male
Age
30
Weight Kg
80
Height Cm
178
TDEE = BMR x Activity Factor using gender Male, age 30, weight kg 80, height cm 178.
The calculator lands with bmr at 1,767.5 and tdee at 2,739.63.
