Estimate your Basal Metabolic Rate (BMR), the calories your body burns at rest. This tool gives a quick, science-based estimate you can save or share.
What Is BMR and Why Should You Care?
Ever wondered how many calories your body burns just by existing? No walking, no eating, no Netflix, just you, breathing, thinking, and keeping your internal organs alive. That magical number is your Basal Metabolic Rate (BMR). It’s the silent calorie engine running behind the scenes.
Why Even Estimate BMR?
Because it’s the foundation. Think of BMR as your metabolic baseline, everything you eat, every step you take, every workout you do, sits on top of it. If you know your BMR, you get a clearer picture of how many calories your body really needs to do nothing, so you can build from there.
The Magic (Or Math) Behind the Scenes
This calculator uses the Mifflin St Jeor equation, one of the most trusted formulas in the fitness world today. You simply enter your age, gender, weight, and height. Then poof, the math gives you your resting-calorie estimate.
In Formula Form
Men: 10 × weight (kg) + 6.25 × height (cm) – 5 × age + 5
Women: 10 × weight (kg) + 6.25 × height (cm) – 5 × age – 161
Yes, math is involved, but you don’t have to sweat it, the tool does it for you.
How to Use It
Enter your age, gender, weight (kg), and height (cm). Click Calculate BMR. Get your result - the number of calories your body would burn in a day if you did nothing but rest. Copy it, send it via WhatsApp, or email it to your future self. (Yes, that’s a thing now.) Knowing your BMR helps you set realistic calorie targets, whether your goal is weight loss, maintenance, or gain.
