Mifflin St Jeor Equation Calculator
Men: (10 ร weight) + (6.25 ร height) – (5 ร age) + 5
Women: (10 ร weight) + (6.25 ร height) – (5 ร age) – 161
The Mifflin St Jeor Equation Calculator helps estimate your Basal Metabolic Rate (BMR) using the trusted Mifflin-St Jeor equation.
About the Equation
Developed in 1990, this formula is widely accepted in nutrition science and often preferred over the Harris-Benedict equation.
Inputs Required
- Gender
- Age
- Weight
- Height
- Activity Level
Calculation Logic
Men:
BMR = (10 ร weight) + (6.25 ร height) โ (5 ร age) + 5
Women:
BMR = (10 ร weight) + (6.25 ร height) โ (5 ร age) โ 161
Multiply BMR by activity factor for TDEE.
Example
Male, 40 years, 85 kg, 180 cm, sedentary:
BMR = 1790 calories
TDEE = 1790 ร 1.2 = 2148 calories
Benefits
