Basal Metabolic Rate (BMR) Calculator
Our BMR Calculator helps you determine the number of calories your body needs at complete rest. Understanding your Basal Metabolic Rate is essential for creating effective nutrition and fitness plans tailored to your body’s specific needs. This tool uses scientifically validated formulas to provide accurate results based on your age, gender, height, and weight. With rising health awareness in India, knowing your BMR can help you make informed decisions about your diet and exercise routine. Calculate your BMR today and take the first step towards better health management.
Your Basal Metabolic Rate
How We Calculate Your BMR
We use the Mifflin-St Jeor Equation, which is considered one of the most accurate formulas for calculating Basal Metabolic Rate:
For men: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age(y) + 5
For women: BMR = 10 × weight(kg) + 6.25 × height(cm) – 5 × age(y) – 161
For “other” gender, we use an average of the male and female formulas. Your BMR represents the number of calories your body would burn if you were at complete rest for 24 hours. This value is essential for determining your daily calorie needs based on your activity level.
💡 Smart Nutrition Tips for Indian Users
- Use your BMR as a baseline to plan daily meals that meet your energy requirements without overeating.
- Include protein-rich Indian foods like dal, paneer, and sprouts in every meal to support muscle maintenance.
- Practice portion control with traditional Indian meals by using smaller plates and balancing food groups.
- Stay hydrated with water, coconut water, or buttermilk instead of sugary beverages to support metabolism.
- Incorporate whole grains like brown rice, millets, and whole wheat roti for sustained energy release.
- Time your meals appropriately, especially if practicing intermittent fasting common in Indian culture.
- Combine your BMR knowledge with TDEE calculations to create a personalized nutrition plan for your goals.

These average BMR values from the National Institute of Nutrition, India provide general reference points. Individual BMR can vary significantly based on body composition, genetics, and other factors not accounted for in these averages.
How to Use This Calculator
Gather Your Information
Before using the calculator, collect accurate information about your age, gender, height, and weight. Use a measuring tape for height measurement and a reliable weighing scale for weight. Ensure all measurements are as accurate as possible for the most precise BMR calculation.
Enter Your Details
Fill in all the required fields in the calculator. For height, use centimeters (cm), and for weight, use kilograms (kg). Select your gender from the dropdown menu. Double-check your entries for accuracy before proceeding to the calculation step.
Click “Calculate”
Once all fields are filled correctly, the “Calculate” button will become active. Click it to generate your BMR. The calculator uses the Mifflin-St Jeor Equation, which is widely recognized as one of the most accurate formulas for calculating basal metabolic rate.
Review and Save Your Results
Your BMR will be displayed prominently on the screen. You can copy these results to your clipboard or download them as a PDF for future reference. The results also include helpful information about what BMR means and how you can use this information for health planning.
Apply to Your Health Goals
Use your BMR as a foundation for calculating your Total Daily Energy Expenditure (TDEE) by factoring in your activity level. This will help you create a personalized nutrition plan whether your goal is weight loss, maintenance, or muscle gain.
Use this calculator as often as needed to fine-tune your nutrition decisions and reach your health goals faster.
Frequently Asked Questions
The calculator uses the Mifflin-St Jeor Equation, which is considered one of the most accurate formulas for calculating BMR. However, individual variations in metabolism, body composition, and genetic factors can affect actual BMR. The calculator provides a solid baseline that you can adjust based on your personal experience and results.
BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest in a neutral environment. RMR (Resting Metabolic Rate) is measured under less restrictive conditions and is typically slightly higher than BMR. For practical purposes, they are often used interchangeably, though RMR may be more representative of real-life resting calorie expenditure.
BMR generally decreases with age due to factors like loss of muscle mass, hormonal changes, and reduced cellular activity. On average, BMR decreases by about 1-2% per decade after age 20. This is why older adults often need fewer calories to maintain the same weight compared to when they were younger.
Yes, you can increase your BMR by building muscle mass through strength training, as muscle tissue burns more calories at rest than fat tissue. Other factors that can help include high-intensity interval training, getting adequate sleep, managing stress, and consuming enough protein. However, genetic factors also play a significant role in determining your BMR.
BMR is the foundation for determining your daily calorie needs. By calculating your Total Daily Energy Expenditure (TDEE), which multiplies your BMR by an activity factor, you can determine how many calories you need to maintain your current weight. To lose weight, you need to consume fewer calories than your TDEE; to gain weight, you need to consume more.
While the basic BMR formulas apply universally, Indian body types often have different body composition patterns that can affect metabolic rate. For instance, South Asians tend to have higher body fat percentages at the same BMI as Caucasians, which can slightly lower BMR. However, the standard formulas still provide a reliable baseline for most Indian users.
You should recalculate your BMR whenever there’s a significant change in your weight (5kg or more), body composition, or age. If you’re actively working to change your weight or muscle mass, recalculating every 2-3 months can help you adjust your nutrition plan to reflect your changing metabolism.
