Your BMR, or Basal Metabolic Rate, is the number of calories your body burns just to stay alive at rest — before you factor in any movement, exercise, or daily activity. This calculator estimates your BMR based on your age, sex, height, and weight, using standard formulas.
BMR is the starting point for any accurate calorie or weight management plan, since it’s the baseline your total daily calorie needs build on top of. For the full explanation of how BMR differs from TDEE and why the distinction matters, read our guide on TDEE vs BMR explained, then use our TDEE calculator to get your full daily calorie target.
