About the BMR Calculator
Your Basal Metabolic Rate is the energy your body burns just staying alive. This calculator computes it with the Mifflin-St Jeor equation and shows your total daily burn at all five activity levels.
Like every Pixveil tool, this calculator runs 100% in your browser — the numbers you enter are never uploaded, stored, or seen by anyone, and results appear instantly with every keystroke. Use it as often as you like, on any device, free forever, with no account and no ads chasing you around.
Results are estimates for general information only and are not medical advice. Talk to a healthcare professional before making significant changes to your diet or exercise.
