What Are BMR and TDEE?

BMR (Basal Metabolic Rate) is the amount of energy (calories) your body burns at complete rest, just to keep you alive—think breathing, pumping blood, and keeping your organs functioning. Various factors like body weight, muscle-to-fat ratio, age, sex, and genetics can influence your BMR. Knowing your BMR gives you a baseline for how many calories you need in a day, even if you do nothing else.

TDEE (Total Daily Energy Expenditure) goes a step further by adding the calories you burn through everyday tasks (like walking, cleaning, or working) and exercise. It’s a helpful way to figure out how many calories you actually need each day—whether you’re looking to lose weight, maintain, or build muscle.

Keep in Mind: It’s Only a Starting Point

This calculator is meant to give you a rough idea of your daily calorie needs, but it doesn’t account for every personal factor (like hormones, health conditions, or unique dietary requirements). Think of it as a guide, not a strict rulebook.
