Step 1 — Find your resting energy
Enter age, sex, weight, and height to estimate your resting metabolic rate—the calories your body uses at rest. Ready to add how activity changes it?
Step 2 — Choose your activity level
Pick how active you are: sedentary, lightly active, active, or very active. That choice scales your resting rate and shifts your daily total. Want to see the math?
Step 3 — Calculate your TDEE
Multiply your resting rate by the activity factor to get your Total Daily Energy Expenditure (TDEE). This number shows calories to maintain weight. Curious how to apply it?
Read your TDEE and act
Use TDEE to set goals: eat near it to maintain, below to lose, above to gain. Learn when results need adjustment and what affects accuracy. Want the full breakdown?
