TDEE, your total daily energy expenditure, is your resting metabolism (BMR) multiplied by an activity factor. A common formula estimates BMR from your weight, height, age and sex, then multiplies by roughly 1.2 for sedentary up to about 1.9 for very active. A free TDEE calculator does this in your browser and reports an estimated daily calorie figure.

Open BMR Calculator →TDEE starts with basal metabolic rate, the calories your body uses at rest, commonly estimated with the Mifflin-St Jeor equation from weight, height, age and sex. That BMR is then multiplied by an activity multiplier: about 1.2 for sedentary, roughly 1.375 for light activity, about 1.55 for moderate, and up to about 1.9 for very heavy training. The result is an estimate of the calories needed to maintain your current weight.
These equations are population averages, so your real needs can differ. Use the TDEE figure as a baseline, then adjust based on how your weight actually responds over a couple of weeks. For any medical or dietary plan, consult a professional; the calculator provides a screening estimate, not health advice.
BMR is the calories your body burns at complete rest. TDEE is BMR multiplied by an activity factor to account for daily movement and exercise.
