This calculator uses the Mifflin-St Jeor equation to determine Basal Metabolic Rate (BMR), then multiplies by an activity factor:
Men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 5
Women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161
Activity multipliers: Sedentary ×1.2, Lightly Active ×1.375, Moderately Active ×1.55, Active ×1.725, Very Active ×1.9.
Example: A 30-year-old male, 80 kg, 180 cm, moderately active.
It is a formula developed in 1990 that estimates Basal Metabolic Rate based on weight, height, age, and gender. It is considered more accurate than older equations like Harris-Benedict.
Sedentary means little or no exercise. Lightly active means light exercise 1-3 days per week. Moderately active means moderate exercise 3-5 days per week. Active means hard exercise 6-7 days per week. Very active means very hard exercise or a physical job.
To lose weight, you typically need a caloric deficit of 500-750 calories per day, which results in about 0.5-0.75 kg of weight loss per week. Consult a healthcare professional before starting any diet plan.
