Calculate your Basal Metabolic Rate and estimate the calories your body needs at rest.
BMR stands for Basal Metabolic Rate. It is an estimate of the number of calories your body needs to perform basic functions while at rest.
Your BMR represents energy used for essential functions such as breathing, blood circulation, maintaining body temperature, and supporting normal organ function.
This calculator uses the Mifflin-St Jeor equation, which estimates BMR using your age, gender, weight, and height.
BMR is an estimate and does not account for all factors that can affect individual calorie requirements. It should not be considered medical advice.

A BMR Calculator estimates your Basal Metabolic Rate (BMR), which is the approximate number of calories your body needs to maintain basic functions while at rest. These functions include breathing, circulation and maintaining body temperature.
BMR is commonly estimated using a person's age, sex, height and weight. Different mathematical formulas can produce slightly different estimates.
Our BMR Calculator uses the commonly used Mifflin-St Jeor equation to provide an estimated BMR value.
BMR represents the estimated calories your body uses at rest. Total Daily Energy Expenditure (TDEE) is higher because it also considers physical activity and other daily energy requirements.
Knowing your estimated BMR can provide a starting point for understanding your daily energy requirements. It can be useful when planning general nutrition, fitness or weight-management goals.
BMR is only an estimate and individual calorie requirements can vary depending on activity level, body composition and other factors.
BMR stands for Basal Metabolic Rate. It is an estimate of the energy your body requires to maintain basic physiological functions while at rest.
No. BMR estimates energy used at rest. Your actual daily calorie needs are generally higher because they include physical activity and other daily energy expenditure.
A BMR calculator provides an estimate rather than a direct measurement. Individual metabolism can vary, so calculated results should be treated as a general guide.
