The TDEE Calculator estimates your Total Daily Energy Expenditure — the number of calories you burn each day including exercise and daily activities. It uses both the Mifflin-St Jeor and Harris-Benedict equations with your activity level to provide accurate estimates.
Four modes let you calculate TDEE with each formula individually, compare both side by side, or see a detailed breakdown by activity level. Pairs with our Calorie and BMR calculators for complete nutritional planning.
