Calculate daily calorie needs (TDEE & BMR)
How Calorie Calculation Works (Mifflin-St Jeor)
Formula
BMR = 10×weight(kg) + 6.25×height(cm) − 5×age − (161 or +5)
- 1Calculate BMR using the Mifflin-St Jeor equation (the most accurate widely-used formula).
- 2Men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5.
- 3Women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161.
- 4Multiply BMR by your activity level multiplier to get TDEE (Total Daily Energy Expenditure).
- 5Subtract 500 calories for weight loss (~0.5kg/week) or add 500 for weight gain.
About Calorie Calculator
Calculate your daily calorie needs using the Mifflin-St Jeor equation. Find your BMR and TDEE based on age, gender, weight, height, and activity level.
Frequently Asked Questions
What is BMR vs TDEE?
BMR (Basal Metabolic Rate) is calories burned at rest. TDEE (Total Daily Energy Expenditure) includes BMR plus calories from activity.
How accurate is this calculator?
The Mifflin-St Jeor equation is accurate to within 10% for most people. Individual metabolism varies.
How many calories to lose weight?
A deficit of 500 calories/day below your TDEE results in ~0.5 kg (1 lb) of weight loss per week.
