Calculate Your Daily Calorie Needs

Estimate how many calories you need per day based on your body stats and activity level using the Mifflin-St Jeor equation — the most accurate formula recommended by dietitians.

Activity Level Guide

  • 1.2 — Sedentary: Desk job, little exercise
  • 1.375 — Light: Light exercise 1-3 days/week
  • 1.55 — Moderate: Exercise 3-5 days/week
  • 1.725 — Active: Hard exercise 6-7 days/week
  • 1.9 — Very active: Athlete or physical job + training

Calorie Goals

To lose weight: subtract 500 calories/day (1 lb/week loss). To gain weight: add 300-500 calories/day. Never go below 1,200 calories/day for women or 1,500 for men without medical supervision.
