BMR Calculator
Estimate your basal metabolic rate and total daily calorie needs (Mifflin-St Jeor).
BMR formula (Mifflin-St Jeor)
For men: BMR = 10·w + 6.25·h − 5·age + 5. For women: BMR = 10·w + 6.25·h − 5·age − 161, with weight in kg and height in cm.
From BMR to daily calories
Multiply BMR by an activity factor (1.2 sedentary to 1.9 very active) to get Total Daily Energy Expenditure (TDEE) — roughly the calories to maintain your current weight.
FAQ
What is the difference between BMR and TDEE?
