TDEE Calculator
Estimate total daily energy expenditure.
How it’s calculated
Resting energy comes from Mifflin–St Jeor, then an activity factor scales it to your total daily burn.
TDEE = resting energy × activity factor.
Resting energy = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5 (men) or − 161 (women). Factors: 1.2 sedentary to 1.9 very active.
