About this calculator
Your Total Daily Energy Expenditure (TDEE) is roughly how many calories you burn per day. This calculator estimates your Basal Metabolic Rate with the Mifflin-St Jeor equation, scales it by your activity level, and suggests targets for losing or gaining weight.
Frequently asked questions
What is BMR vs TDEE?
BMR is the calories your body burns at complete rest. TDEE multiplies BMR by an activity factor to include movement and exercise — it is the number you eat around to maintain weight.
How many calories to lose weight?
A deficit of about 500 calories a day is a common target for losing roughly half a kilogram (about one pound) per week. Do not go below what is safe for you.
