Metabolism Calculator

Estimate your basal metabolic rate (BMR) and approximate daily calorie needs.

Formula (Mifflin-St Jeor Equation):

For Men:
BMR = 10 × weight + 6.25 × height - 5 × age + 5

For Women:
BMR = 10 × weight + 6.25 × height - 5 × age - 161

Daily Calorie Needs = BMR × Activity Factor

This gives an estimate of the calories your body burns at rest and daily based on activity.
