Daily Calorie Needs Calculator for Women

Knowing your daily calorie needs helps you make informed choices about your diet — whether your goal is maintaining your current weight, losing body fat, or gaining weight for health or pregnancy. Our calorie calculator uses the Mifflin-St Jeor equation, the most accurate formula for women.

How Calorie Needs Are Calculated

Your Total Daily Energy Expenditure (TDEE) is the number of calories you burn each day, accounting for your Basal Metabolic Rate (BMR) and activity level. Your BMR is the calories needed just to keep your body functioning at rest. Multiply by an activity factor (1.2–1.9) to get your TDEE.

Calorie Needs Change in Women's Health

  • TTC: Focus on nutrient density over calories — add 400mcg folate daily
  • Pregnancy: Add ~300 extra calories/day from the 2nd trimester
  • Breastfeeding: Add ~500 extra calories/day to support milk production
  • PCOS: Calorie quality matters more than quantity — focus on low-GI foods
  • Menopause: Calorie needs decrease as muscle mass declines with age
