How Many Calories a Day for a Woman?
In short
There is no single number that applies to "women". Official tables give a population range, not a personal prescription — your own estimate comes from your BMR and your activity level.
There is no single figure that holds for "women": age, height, weight, activity level and life stage (menstrual cycle, pregnancy, breastfeeding, menopause) all move the real energy requirement. What reference tables give you is an order of magnitude for a population, not an individual prescription.
Why there is no single number
Calorie needs rest on two building blocks: BMR (basal metabolic rate, the energy you spend at rest) and TDEE (BMR × an activity factor). For women, BMR depends on weight, height and age — equations such as Mifflin-St Jeor use a different constant for women than for men, precisely because average muscle mass differs. TDEE then varies with activity, exactly as it does for men. If the goal is simply eating well day to day, our eating well, day to day guide picks this up.
What health authorities publish
The nutritional reference values used for the French population are set by the ANSES opinion updating the PNNS reference points (in French), which gives energy reference points by age bracket and sex for a given level of physical activity — not a single number. The EFSA publishes European reference values built on the same logic (BMR × physical activity level). Those documents make the point themselves: these are population reference points, to be adjusted to the individual.
To stay honest about what we state: this article does not reproduce a fixed kcal figure from those documents until it has been checked against the primary source by our dietetics reviewer — a mis-copied number would be worse than no number at all.
Note for readers outside Europe: the sources cited above are European. National bodies in the United States, Canada and Australia publish their own energy reference tables, built on the same BMR × activity logic. We only cite sources our dietetics reviewer has gone through, so we point to the two above rather than to a table we have not sourced ourselves.
Pregnancy, breastfeeding, menopause: outside the generic calculation
The generic BMR/TDEE calculation does not apply as-is during pregnancy or breastfeeding (additional requirements are documented by ANSES and the WHO) or in specific medical situations. In those cases, the advice of a healthcare professional takes precedence over any online calculator.

An individual calculation (BMR from weight, height and age, then an activity factor) is still the best approach available without medical equipment — see our article "How many calories a day?" for the full method. Tracking what you actually eat over a few weeks then lets you adjust the estimate to your own body, rather than relying on a national average. If this is part of a weight-loss effort, our calorie counter for gentle weight loss guide covers it separately.
FAQ
Is there a standard daily calorie figure for women?
No. Official tables publish ranges by age, sex and activity level, and state that they are population reference points to be adjusted to the individual.
Why do BMR equations use a different constant for women?
Because average body composition differs, in particular average muscle mass, which drives energy expenditure at rest.
Does the calculation still apply during pregnancy or breastfeeding?
No. Additional requirements are documented by health authorities, and a healthcare professional should be consulted rather than an online calculator.
General information, not medical advice. If you are pregnant, breastfeeding or in a specific medical situation, talk to a healthcare professional.
