TDEE calculator
TDEE is a daily energy estimate: the Mifflin–St Jeor resting figure times an activity multiplier. It is not a measurement and it is not a target for how much to eat.
The resting figure is explained on the BMR page, which uses the same equation. Use that page if you want the formula written out on its own.
Calculator
Required fields are marked with *.
Use a comma or a dot for the decimal, as in 12.5 or 12,5. Type thousands as 1000 or 1 000. A single comma or dot is the decimal mark, so 1,000 means 1.

How to use this calculator
- Enter age, height, and weight for an adult, and choose the sex coefficient.
- Pick the activity level. Each option shows its multiplier.
- Read the daily estimate first. The resting estimate is beside it.
Formula
BMR (men) = 10×kg + 6.25×cm − 5×age + 5
BMR (women) = 10×kg + 6.25×cm − 5×age − 161
Daily calories are that result times 1.2, 1.375, 1.55, 1.725, or 1.9. Those factors are conventional planning numbers. Two people with the same label can use very different amounts of energy.
Worked example
A 40-year-old man, 180 cm, 80 kg, sedentary
The resting estimate is 1,730.
Times 1.2, the daily estimate is 2,076.
About 2,076 daily calories. Resting estimate 1,730.
Questions
Should I eat exactly this number?
No. Illness, pregnancy, and some medicines change energy needs. A dietitian or clinician can put the figure in context.
How is this different from the BMR page?
The equation is the same. This page leads with the daily calorie estimate. The BMR page leads with the resting figure and the same multipliers.
Are the activity levels measured?
No. They are labeled estimates. “Sedentary × 1.2” is not a laboratory result.
