Calorie Calculator
Estimate your Total Daily Energy Expenditure (TDEE) based on your age, gender, height, weight, and activity level. Use this to find out how many calories you need to maintain, lose, or gain weight.
Estimate your daily calorie needs using the Mifflin-St Jeor, Revised Harris-Benedict, or Katch-McArdle formula. Results show your maintenance calories plus weight-change targets.

Mifflin-St Jeor (recommended)
Male: BMR = 10W + 6.25H − 5A + 5
Female: BMR = 10W + 6.25H − 5A − 161
Revised Harris-Benedict
Male: BMR = 13.397W + 4.799H − 5.677A + 88.362
Female: BMR = 9.247W + 3.098H − 4.330A + 447.593
Katch-McArdle (requires body fat %)
BMR = 370 + 21.6 × (1 − F) × W
W = weight (kg) · H = height (cm) · A = age · F = body fat fraction
