This TDEE calculator finds your total daily energy expenditure — the calories you burn in a day — by scaling your BMR by an activity factor. Enter your details above.
Formula
TDEE = BMR × activity factor
Sedentary 1.2 | Light 1.375 | Moderate 1.55 | Active 1.725 | Very active 1.9
Example
BMR 1,780, moderately active (1.55): TDEE = 2,759 kcal/day.
Eat around TDEE to maintain weight, below it to lose, and above it to gain.

Frequently Asked Questions
What is TDEE?
Total daily energy expenditure — all the calories you burn in a day, including activity, on top of your basal metabolic rate.
How do I calculate TDEE?
Multiply your BMR by an activity factor from about 1.2 (sedentary) to 1.9 (very active).
How do I use TDEE for weight loss?
Eat below your TDEE for a deficit; a moderate 300-500 kcal deficit is a common, sustainable approach.
