🔥 BMR Calculator — Estimate Your Basal Metabolic Rate
Welcome to our Free Online BMR Calculator, the easiest way to estimate your Basal Metabolic Rate (BMR) — the number of calories your body burns at rest. This tool helps you understand how many calories you need each day just to maintain basic body functions like breathing, circulation, and cell production.
No sign-up, no login — just simple, instant results based on your personal information. It works on phones, tablets, and desktops.
🧠 What Is BMR?
Basal Metabolic Rate (BMR) is an estimate of the minimum calories your body needs each day if you were at rest all day. BMR doesn’t include calories burned from physical activity — it only reflects the energy used for essential internal functions.
Knowing your BMR can help with:
Weight loss or gain planning
Setting daily calorie goals
Monitoring metabolic changes over time
🧮 How It Works
To calculate your BMR, the tool uses your:
Age
Gender
Height
Weight
Some calculators also include your activity level to estimate your total daily energy expenditure (TDEE), which shows how many calories you burn including daily movement.

🔎 Tips for Better Understanding Your Results
Your BMR is just the starting point — actual calorie needs depend on day-to-day activity.
If you’re trying to lose weight, aim for a calorie intake slightly below your daily energy needs (safely and gradually).
If you want to gain weight, eat more nutrient-rich calories than your body uses.
✨ Note: This calculator gives you an estimate based on widely accepted formulas. For personalized health or diet planning, consulting a healthcare or nutrition professional is always best.
