BMR Calculator

The Basal Metabolic Rate (BMR) represents the absolute minimum number of calories your body requires to maintain basic physiological functions while in a complete state of rest. These functions include respiration, blood circulation, cellular synthesis, and body temperature regulation. Because BMR accounts for roughly 60% to 75% of your total daily energy expenditure, calculating this metric helps you better plan your nutrition and manage your weight.

Here you can instantly calculate your BMR. The tool utilizes the Mifflin-St Jeor equation, incorporating your specific age, gender, height, and weight. Once your baseline BMR is established, you can select your current physical activity level. The calculator then instantly computes your Total Daily Energy Expenditure (TDEE). With your TDEE, you can plan your diet to lose, maintain, or gain weight. All biometric computations are executed strictly within your local browser, keeping your data private. This tool is completely free to use and requires no registration.

It is important to note that these calculations provide estimates and individual results may vary based on other factors. This tool is provided for informational purposes only and does not substitute professional medical or nutritional advice.
