BMR estimates calories used at rest from weight, height and age. Daily calorie needs are higher after activity is considered.

Formula: Mifflin–St Jeor: Men = 10W + 6.25H − 5A + 5; Women = 10W + 6.25H − 5A − 161

Enter age, body measurements, dates, or activity choices exactly as requested. These calculators estimate a result from the inputs rather than directly measuring a physical condition.

Repeat the calculation with the same values to confirm the output, then review the unit and method before interpreting the number.

Frequently Asked Questions FAQ

What is BMR?
BMR stands for Basal Metabolic Rate, which represents the number of calories your body needs to maintain basic bodily functions at rest. It accounts for the energy required for essential functions like breathing, digestion, and circulation.
How is BMR calculated?
BMR can be estimated using various formulas, with the most commonly used being the Mifflin-St Jeor equation. This equation takes into account factors such as weight, height, age, and gender to estimate BMR. Other equations like the Harris-Benedict formula or Katch-McArdle equation may be used, depending on specific factors like body composition.
