Understanding This Calculator
BMR Formula (Mifflin-St Jeor)
The Mifflin-St Jeor equation is considered one of the most accurate methods for estimating BMR.
Men: (10 × weight) + (6.25 × height) - (5 × age) + 5
Women: (10 × weight) + (6.25 × height) - (5 × age) - 161
- Weight: in kilograms (kg)
- Height: in centimeters (cm)
- Age: in years
Example 1
Male, 30 years old, 80 kg, 180 cm.
- Calculation: (10×80) + (6.25×180) - (5×30) + 5
- 800 + 1125 - 150 + 5 = 1,780 kcal/day
Example 2
Female, 25 years old, 60 kg, 165 cm.
- Calculation: (10×60) + (6.25×165) - (5×25) - 161
- 600 + 1031.25 - 125 - 161 = 1,345 kcal/day
How to Use
- Enter weight, height, and age.
