Calculate your Basal Metabolic Rate (BMR) - the number of calories your body burns at complete rest.
| Basal Metabolic Rate | |
| Calories/day at rest | calories |
This is the number of calories your body burns at complete rest just to maintain basic functions. Multiply by an activity factor (see our TDEE Calculator) to estimate your total daily calorie needs.
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic life-sustaining functions like breathing, circulation, and cell production, while at complete rest. This calculator uses the Mifflin-St Jeor equation, the most widely used and research-backed BMR formula.
BMR does not include calories burned through daily activity or exercise. To estimate your total daily calorie needs including activity, use our TDEE Calculator.

This calculator uses the Mifflin-St Jeor equation, the most widely used and research-backed BMR formula.
BMR does not include calories burned through daily activity or exercise. To estimate your total daily calorie needs including activity, you would use a TDEE calculator.
It calculates your BMR based on standard inputs used in the Mifflin-St Jeor equation, such as age, gender, height, and weight.
BMR tells you the calories your body burns at complete rest, forming the baseline used to calculate total daily calorie needs.
