About BMR Calculator
BMR Calculator is a free online tool that estimates your Basal Metabolic Rate — the number of calories your body burns at rest to maintain basic functions like breathing and circulation.
Using the Mifflin-St Jeor equation, enter your gender, age, weight, and height to instantly see your estimated daily BMR in calories.
This tool is useful for anyone planning a diet, fitness routine, or calorie budget, since BMR forms the baseline for calculating total daily energy needs.
