Calorie Calculator
Estimate daily calorie needs for weight maintenance, loss, or gain.
What Is the Calorie Calculator?
A calorie calculator estimates your Total Daily Energy Expenditure (TDEE). The calories you burn in a day including all activity. Use this to set targets for weight maintenance, loss, or gain.
The Formula
TDEE = BMR x Activity Multiplier (1.2 sedentary to 1.9 very active).
Example
A moderately active 35-year-old man with a BMR of 1,765 calories needs about 2,735 calories daily to maintain his current weight. To lose one pound per week, he should target roughly 2,235 calories. For muscle gain, aiming for 3,235 calories supports building mass.
Common Uses
Weight loss planning, muscle building, athletic performance, general nutrition.
