Calorie Calculator for Women
Understanding your daily calorie needs is key to reaching your health and fitness goals. This calorie calculator for women uses the Mifflin-St Jeor equation — the gold standard for BMR estimation — and factors in your activity level to give you a personalized TDEE (Total Daily Energy Expenditure).
How many calories should a woman eat per day?
Calorie needs for women vary by age, height, weight, and activity. A sedentary woman may need around 1,600–2,000 calories per day, while an active woman could need 2,200–2,800 or more. The calculator below gives you a number tailored to your body.
Factors that affect women's calorie needs
- Age: BMR decreases slightly with age after the 20s.
- Body composition: More lean muscle increases resting metabolism.
- Activity level: Everything from daily walking to intense training.
- Hormonal factors: Menstrual cycle, pregnancy, and menopause can affect metabolism.
What is BMR for women?
Your Basal Metabolic Rate (BMR) is the number of calories your body burns at complete rest. For women, the Mifflin-St Jeor formula is:
BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161
Activity levels for women
- Sedentary (1.2): Little or no exercise, desk job
- Light (1.375): Light exercise 1–3 days/week
- Moderate (1.55): Moderate exercise 3–5 days/week
- Very active (1.725): Hard exercise 6–7 days/week
- Extra active (1.9): Intense daily training or physical job
