BMR & TDEE Calculator

Calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) to better understand your body's energy needs.

Calculate Your BMR & TDEE

Sedentary (little or no exercise)

Understanding BMR and TDEE

Your Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic, life-sustaining functions while at rest. These essential functions include breathing, circulation, cell production, nutrient processing, and maintaining body temperature.

Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a 24-hour period. It includes your BMR plus the calories burned during physical activity, digestion, and other daily movements. Knowing your TDEE is crucial for effective weight management, whether you aim to lose, gain, or maintain your current weight.

Activity Levels Explained:

Sedentary

little or no exercise

Lightly active

light exercise/sports 1-3 days/week

Moderately active

moderate exercise/sports 3-5 days/week

Very active

hard exercise/sports 6-7 days a week

Super active

very hard exercise/physical job

This calculator uses the Mifflin-St Jeor equation, a widely accepted formula for estimating BMR, and then applies an activity multiplier to determine your TDEE.
