Enter your details to calculate your BMR
How is your BMR calculated?
We use the Mifflin-St Jeor equation as the default — it is the most validated formula for estimating resting calorie burn in modern populations. The Harris-Benedict Revised equation is also available as an alternative; it tends to produce slightly higher estimates.
Your BMR is not your calorie target — it is the floor. To get your actual daily calorie needs, multiply by your activity level using our TDEE Calculator.

Frequently asked questions
BMR (Basal Metabolic Rate) is the number of calories your body burns at complete rest just to keep you alive — breathing, circulating blood, cell repair, and organ function. It does not include any activity, digestion, or exercise.
