How it's calculated
Men: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age + 5. Women: BMR = 10×weight(kg) + 6.25×height(cm) − 5×age − 161. TDEE = BMR × Activity Multiplier.

About this calculator
The BMR Calculator computes your Basal Metabolic Rate - the calories your body burns at rest - using the Mifflin-St Jeor equation, then multiplies it by an activity factor to estimate your Total Daily Energy Expenditure (TDEE).
Frequently Asked Questions
BMR (Basal Metabolic Rate) is the number of calories your body needs to maintain basic life functions - breathing, circulation, cell production - while completely at rest.
BMR is calories burned at rest, while TDEE adds your daily activity level on top, giving a more realistic estimate of total daily calorie burn.
It uses the Mifflin-St Jeor equation, which is widely regarded by nutrition professionals as more accurate than older formulas like Harris-Benedict.
