About Calorie Calculator

The Calorie Calculator estimates the daily calories required to maintain, lose, or gain weight. It is designed to compute your Basal Metabolic Rate (BMR) and your Total Daily Energy Expenditure (TDEE).

Mifflin-St Jeor Formula:

  • Men BMR: 10 * weight (kg) + 6.25 * height (cm) - 5 * age (y) + 5
  • Women BMR: 10 * weight (kg) + 6.25 * height (cm) - 5 * age (y) - 161

This BMR is multiplied by activity multipliers ranging from 1.2 (sedentary) to 1.9 (highly active) to find TDEE.
