Calorie Calculator
Estimate your daily calorie needs (TDEE) from your body stats and activity level.
Daily calorie needs (TDEE)
2,430 kcal
- Base metabolic rate (BMR)
- 1,568 kcal
- Daily needs (TDEE)
- 2,430 kcal
How this is calculated
BMR is calculated with the Mifflin-St Jeor equation from your weight, height, age, and sex. TDEE multiplies BMR by an activity factor ranging from 1.2 (sedentary) to 1.9 (very active).

Frequently asked questions
What formula does this use?
The Mifflin-St Jeor equation, widely considered one of the more accurate formulas for estimating basal metabolic rate (BMR), multiplied by an activity factor to estimate total daily energy expenditure (TDEE).
Should I eat exactly my TDEE every day?
TDEE is your maintenance calorie level — eating below it typically leads to weight loss and above it to weight gain, but individual metabolism varies. Treat this as a starting estimate to adjust based on your own results over a few weeks.
