About the BMR Calculator

The BMR Calculator estimates your Basal Metabolic Rate, the number of calories your body burns at rest. You enter basic body details and get a daily calorie figure you can use for weight management and nutrition planning.

The calculator uses the Mifflin-St Jeor equation, a standard formula for estimating resting energy needs. It requires your age, sex, height, and weight. For a more complete picture, add your activity level to convert BMR into total daily calorie needs. Since results are estimates, consider a healthcare professional or dietitian for personal nutrition decisions.

  • Choose your units and enter your age, sex, height, and weight.
  • Press calculate to see your BMR in calories per day.
  • Apply an activity multiplier to estimate your total daily calorie needs.
