TDEE Calculator
Enter your sex, weight, height, age and activity level to estimate your Total Daily Energy Expenditure (TDEE) — roughly how many calories you burn per day.

This is a population-average estimate for general planning, not medical advice.
How It Works
TDEE starts from your Basal Metabolic Rate (BMR), the calories your body burns at rest, then multiplies it by an activity factor reflecting how much you move throughout the day.
Formula
BMR (Mifflin-St Jeor) = 10×weight(kg) + 6.25×height(cm) − 5×age + 5 (men) or − 161 (women). TDEE = BMR × activity multiplier.
Example
A 30-year-old man weighing 80 kg at 180 cm with a moderately active lifestyle has an estimated TDEE of roughly 2,700 calories per day.
Frequently Asked Questions
- Is this an exact number?
- No. This is a population-average estimate using the Mifflin-St Jeor equation. Individual metabolism varies, so treat this as a starting point rather than a precise measurement.
- How do I use TDEE for weight goals?
- Eating close to your TDEE tends to maintain weight, eating below it tends to support weight loss, and eating above it tends to support weight gain — always in the context of overall health, not this estimate alone.
