BMR Calculator

Your Basal Metabolic Rate (BMR) is the number of calories your body needs just to stay alive at rest.

How BMR is calculated

We use the Mifflin-St Jeor equation, widely considered the most accurate for the general population:

• Men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5
• Women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161

To turn BMR into your daily calorie needs, multiply by an activity factor — use our calorie (TDEE) calculator.
