BMR & Daily Calorie Calculator
Your Basal Metabolic Rate is the minimum number of calories your body needs to maintain essential functions at rest. Calculate your BMR and Total Daily Energy Expenditure (TDEE) to build a nutrition plan grounded in your actual physiology, not guesswork.

What This Means for Your Diet
Your BMR is your absolute baseline. If you are trying to lose weight in a typical Indian diet heavy in carbohydrates, never drop your calories below this number—doing so can crash your metabolism and lead to muscle loss.

BMR and Calorie Planning for Smarter Nutrition Decisions
Most generic diet advice is built around a 2,000-calorie assumption that fits nobody's actual body perfectly. Your real calorie need depends on your age, height, weight, body composition, and how physically active your daily life actually is — not the idealised "moderately active adult" that nutrition labels are written for. BMR (Basal Metabolic Rate) is the starting point for a personalised estimate: the calories your body burns just to stay alive if you did nothing all day.
From BMR, your total daily calorie need is calculated by applying an activity multiplier that accounts for exercise, walking, and physical work. For a desk job professional who does 30 minutes of moderate exercise three times a week, total daily calorie need is typically 1.5 to 1.6 times BMR. For a physically demanding job or heavy gym training, it can be 1.7 to 1.9 times.
For Indian users planning fat loss, maintenance, or muscle-building nutrition get a personalised starting estimate. It is most valuable as a baseline from which to adjust — not as a rigid daily rule. Real-world progress, hunger levels, and energy are better feedback mechanisms than a fixed number.
How Daily Calorie Needs Are Estimated
Enter your age, height, weight, sex, and activity level. The calculator uses the Mifflin-St Jeor formula — widely considered the most accurate standard equation for general use — to estimate your BMR. It then applies the appropriate activity multiplier to show your Total Daily Energy Expenditure (TDEE), which is your estimated maintenance calorie level.
From maintenance calories, you can calculate your target intake: subtract 300-500 calories per day for gradual fat loss, add 200-300 for a controlled muscle-building surplus. Those moderate adjustments produce results without the metabolic slowdown and nutrient deficiency that accompany extreme calorie restriction.
A Desk-Job Calorie Check
You are 30 years old, weigh 72 kg, are 175 cm tall, and exercise moderately 3-4 times per week.
- 1Enter age (30), weight (72), height (175), sex, and activity level (moderately active).
- 2Review the BMR and the TDEE (maintenance calories) shown.
- 3If your goal is fat loss, subtract 400 from TDEE. That is your daily calorie target.
You get a personalised estimate — likely 2,100-2,400 maintenance calories at this profile — instead of following a generic diet built for an average person with a different body and lifestyle.
When Food Planning Needs a Baseline
- Before starting a fat-loss or muscle-gain plan, to establish a more personalised calorie baseline than a generic 1,500 or 2,000 calorie target.
- When your weight plateau persists despite following a plan, to check whether your original calorie target was set incorrectly.
- After a significant change in body weight — dropping 5-8 kg — because BMR decreases as body weight decreases, meaning your calorie target needs adjustment.
- When transitioning from a very sedentary period (recovery from illness, desk-only lifestyle) to an active routine, to recalculate your new daily calorie need.
- When evaluating nutrition advice that recommends a specific calorie target, to check whether it matches your individual profile before following it.
Activity Assumptions to Be Honest About
- Gives a more accurate starting calorie range than generic diet advice or 1-size-fits-all apps.
- Shows the meaningful difference between sedentary, lightly active, and moderately active daily calorie needs.
- Useful for adjusting nutrition plans as weight and activity level change over time.
- Calorie estimate reality check: The number shown is an estimate, not a metabolic measurement. Individual metabolic variation means actual calorie needs can differ by 10-15% in either direction. Treat the result as a starting point and adjust based on real-world progress over 2-3 weeks.
- Activity-level mistake: Overestimating activity level is the most common mistake. If you have a desk job and walk 20 minutes a day, "lightly active" is correct — not "moderately active." Overestimating activity inflates the calorie target and explains why many people do not lose weight despite "eating less and moving more."
- Metabolism caveat: This is a screening and planning estimate, not a clinically measured value. It does not account for thyroid function, hormonal conditions, medication effects, or metabolic adaptations from long periods of calorie restriction. If your results consistently differ from the estimate, consult a registered dietitian.
- After setting the calorie baseline: This is not medical advice. Before making significant dietary changes, especially if you have any health conditions, consult a qualified healthcare professional. Use this estimate as an awareness and planning reference, not a prescription.
