Daily Calorie Calculator
Formula
BMR = 10×weight + 6.25×height − 5×age + 5 (male)
The Mifflin-St Jeor equation estimates your Basal Metabolic Rate (BMR) — calories burned at rest. Multiply by your activity factor for Total Daily Energy Expenditure (TDEE). Note: this uses the male formula. Female formula subtracts 161 instead of adding 5.
