Enter your details to calculate your BMR
How is your calorie deficit 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
Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic life functions at complete rest — breathing, circulation, cell production, and temperature regulation. It accounts for roughly 60–70% of your total daily calorie burn.
