**Health Calculators** ▶ BMR Calculator

Basal Metabolic Rate Calculator or BMR Calculator is a tool to know the minimum amount of energy your body needs to stay alive. BMR meaining is Basal Metabolic Rate mostly depends upon the muscular mass a body has. Calculating BMR is important because if you don’t know what is that least amount of calories your body needs, you may end up as tired and lethargic. Your body will not be performing its basic functions. So it’s better to get an idea of BMR using this Basal Metabolic Rate Calculator.

**Are You on Weight Loss Mission and Eager to Know What’s That Least Amount of Calories You Need to Stay Alive then This BMR Calculator is the Tool You Need?**

BMR Calculator or Basal Metabolic Rate Calculator tells you the number of calories your body needs to keep functioning well. If you want to know what my BMR then you need to calculate BMR using this BMR Calculator. Basal Metabolism depends upon the muscle mass you have in your body. If you are more muscular than your BMR will be higher than the person who is just fat but doesn’t have good muscles. And your muscles need energy to keep performing, and if your body doesn’t get the least amount of energy, it will loosen your muscles, and you’ll start feeling tired and lethargic.

As we narrated above that BMR or Basal Metabolic Rate is the consumption of calories by the body at zero activity level. In other words, this is the amount of energy you need for your healthy survival. And if your body won’t get this minimum amount of calories, basal metabolism will decline, and you will start feeling tired with no energy to do anything. So it’s important for every person to calculate BMR and how to calculate BMR, you can calculate basal metabolic rate with the ease of our efficient Basal Metabolic Rate Calculator.

This BMR calculator is designed for the layman so that everyone can use it easily. No technical skills or BMR formula is required here. All you need to do is to put in the basic figures like your age, gender, your weight, and your daily activity level and calculate BMR by clicking or tapping on the calculate button. While putting in the information, be assured that this information you are providing us while calculating BMR is never stored anywhere, nor will be used for any other purpose. This information is used only to calculate your BMR, and as you leave the page or site, the information is no more these.

Given three equations are utilized by our base metabolic rate calculator:

**For men:**

BMR = 10W + 6.25H – 5A + 5

**For women:**

BMR = 10W + 6.25H – 5A – 161

**For men:**

BMR = 13.397W + 4.799H – 5.677A + 88.362

**For women:**

BMR = 9.247W + 3.098H – 4.330A + 447.593

BMR = 370 + 21.6(1 – F)W

Where:

- W is body weight in kg
- H is body height in cm
- A is age
- F is body fat in percentage

This Basal Metabolic Rate Calculator can be a handy tool for people want to lose weight. We have often observed the people who started their weight loss mission without proper information, soon we found them in the hospital because they felt that staring is the only way to lose weight and in order to lose weight, they forgot that their body need a certain amount of calories daily to perform routine tasks like breathing, thinking, blood supply, digestion, etc. And when your body doesn’t get this energy, more are the chances that you will get faint.

So, if you want to lose weight, the first thing that you need to know is your BMR. Calculate BMR using this Basal Metabolic Calculator and keep it in mind while planning your diet for weight loss. If your body has fat, you can afford to keep daily intake of calories lower than your BMR because in such case your body fat will be used to fulfill the gap and hence you will start losing the fat.

But if your body doesn’t have fat but muscles only, you must take care of your BMR. You can’t take lesser calories than least required amount of energy else your body will not perform well.

List of factors which may have a direct or indirect but a considerable effect on your BMR is long. Here we will discuss a few of the factors that affect BMR.

**Age:** It is the most important factor in most of body-related indices and ratios like BMR, RMR, BMI, etc. the first thing you need to know while calculating BMR is your age. Age is directly used in BMR formula, and BMR is inversely proportional to age, i.e. higher age, lower the BMR will be.

**Gender:** It is another factor that decides your BMR while calculating BMR. Men are normally more muscular mass, so their BMR is normally higher than the women.

**Daily Activity:** It is the factor that affects BMR figures. If you are active and exercise daily, your BMR will be high. While, on the other hand, if you don’t have active routine and exercise is something you don’t even care about then your BMR will be much lower than an active person.

**Body size:** keep in mind the metabolic rate increases as height, weight and even the surface area increase.

**Body composition:** According to experts, if the lean muscle mass increases, then the metabolic rate also increases. Also, the fat tissue has a lower metabolic activity than the muscle tissue.

**Climate and body temperature:** The people who live in tropical climates areas generally have 5-20 percent higher BMR than individuals who live in more temperature areas as it takes energy to keep the body cool. Remember that exercise/physical activity that performed in hot weather also imposes an additional metabolic load.

**Hormonal Levels:** Thyroxine (T4) is the key hormone that has a significant effect upon BMR and it is released by the thyroid glands. Hypothyroidism is a condition that is relatively common, especially in female near or after menopause. Additionally, an individual with a weight problem and if his/her thyroid function turns out to be low, then he/she should have to consult with a health care providers for treatment.

**Health:** Optimistic studies reveal that illness, fever, or injury can increase resting metabolic rate (RMR) two-fold.

Well, what so ever, you don’t need to get involved in complex calculations using basal metabolic rate formula rather keep it simple using this BMR Calculator or Basal Metabolic Calculator.

It is very simple and easy, you can readily do the math yourself with the ease of the given equation:

If you are a man, then;

BMR = (6.23 x weight in pounds) + (12.7 x height in inches) – (6.8 x age in years)

**For Example;**

Weight = 170 pounds

Height = 5’11’’

Age = 43

BMR = 66 + (6.23 x 170) + (12.7 x 71) – (6.8 x 43) = 1,734.4 calories

If you are a woman, then;

BMR = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) – (4.7 x age in years)

**For Example:**

Weight = 130 pounds

Height = 5’3’’

Age = 36

BMR = 665 + (4.35 x 130) + (4.7 x 63) – (4.7 x 36) = 1,357.4 calories

Very next, there is a need to calculate your daily caloric requirement by multiplying your BMR by your level of activity:

- If you are rarely exercising, then you have to multiply your BMR by 1.2
- If you have exercise on 1-3 days per week, then you have to multiply your BMR by 1.375
- If you have exercise on 3-5 days per week, then you have to multiply your BMR by 1.55
- If you have exercise 6-7 days per week, then you have to multiply your BMR by 1.725
- If you have exercised every day and have a physical job or even exercise twice per day, then you have to multiply your BMR by 1.9

**From the above examples:**

If a man exercises 3 days a week, then his daily caloric requirement is 1,734.4 x 1.55, or 2,688.3 calories.

If a woman only sticks on exercise routine 6 days/week, then her daily caloric requirement will be 1,357.4 x 1.725 or 2,342.5 calories.

Normally, men have a BMR of about 1,600-1,800 kCals a day and when it comes to women; they have a BMR of 1,550 kCals a day. But remember that this is variable.

It is best to use the above calculator to track your BMR!

All you need is your height, weight, and age to perform such calculations! If you want to get weight in KG, then you ought to divide your weight in pounds by 2.2. And, if you want to calculate your height in centimeters, then there is a need to multiply the inches by 2.54.

**For men:**

BMR = (9.99 x weight in kilograms) + (6.25 x height in centimeters) – 4.92 x age in years + 5.

**For women:**

BMR = (9.99 x weight in kilograms) + (6.25 x height in centimeters) – (4.92 x age in years) – 161.

Well, these predictive equations just provide a baseline for estimating calories, and remember that the metabolic rates vary due to genetics and muscle mass.

BMR = 1766 Kcal/day

According to experts, RMR value represents on average 50 percent to 70 percent of an individual’s daily energy expenditure. Keep in mind, your BMR is something that slows down at roughly 2 percent every 10 years after the age of 20. That’s the prominent reason why most people gain weight as they get older while maintaining the same caloric count.

Well, an individual body’s composition of lean muscle and fat is indicated as LBM or lean body mass, it is a key indicator that has the ability to maintain a high BMR in the long-term. However, an individual with higher lean body mass (LBM) will enjoy a higher BMR than someone at the same weight with a higher percentage of fat and even also naturally burn more calories.

According to several studies, any amount that is less than your normal total daily energy expenditure (TDEE) may cause to lose excess flab, it just based on how quickly you to see outcomes. Medical experts reveal that an individual need to subtract 500 calories from his/her diet each day to lose one pound of fat per week.

As we mentioned above there are several factors that influence BMR, your metabolic rate increases as your weight, height, and surface area increase.

BMR is said to be as the number of calories required to keep your body functioning at rest. Sometimes BMR is referred as body’s metabolism, that’s why any increase to your metabolic weight like exercise, will increase your BMR. To track your BMR, you just have to enter the values into the designated field of the above accurate bmr calculator.
