The first step in using the Expenditure and Energy Requirement Calculator is to provide your personal information. This data is essential for the calculator to estimate your daily energy expenditure accurately. The following details will be required:
Your weight is one of the key factors used to calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). To enter your weight:
Your height is also used in the calculation to estimate your BMR. Height affects the overall energy requirement because taller individuals generally have more muscle mass and a higher BMR. To input your height:
Age plays a significant role in energy calculations because metabolic rate generally decreases as you get older. The calculator adjusts your energy needs based on your age. To provide your age:
Gender is another important factor influencing your metabolic rate. Typically, men have higher energy needs than women due to differences in muscle mass and hormonal influences. The calculator provides gender-specific formulas to calculate your energy expenditure. To select your gender:
Once you have entered your personal information, the next step is to choose the formula that will be used to calculate your energy expenditure. Different formulas have been developed over the years to provide more accurate estimates of daily energy needs. Below are the three available formulas for calculation:
The Harris-Benedict formula, developed in 1919, is one of the oldest and most widely used methods for calculating Basal Metabolic Rate (BMR). This formula takes into account weight, height, age, and gender to estimate the number of calories you burn at rest. It has been a trusted approach for many years, although newer formulas may provide more accurate results for specific populations.
In 1984, Roza and Shizgal recalculated the Harris-Benedict formula to improve its accuracy. This revised formula considers more recent data, which may make it more relevant for certain populations. It provides a more refined estimate of BMR and energy expenditure based on updated measurements.
The Black & al (1996) formula offers a modern approach to calculating energy expenditure. It incorporates data from a variety of studies and is based on a more comprehensive understanding of how body composition, such as muscle mass, affects metabolism. This formula is especially helpful for individuals with specific needs and goals, including those focused on physical fitness and muscle development.
Once you have input your personal details and selected your preferred calculation formula, the Expenditure and Energy Requirement Calculator will generate your energy expenditure results. These results include the total number of calories your body burns in a day, as well as different energy requirements based on your activity level. Here are the key results you will receive:
This value represents the total amount of calories your body needs to perform all its daily functions, including basic physiological functions like breathing, digestion, and circulation, as well as any physical activity. The total energy expenditure (TDEE) is the sum of your Basal Metabolic Rate (BMR) and the calories burned through physical activities.
This value estimates the number of calories you need if you lead a sedentary lifestyle, meaning you engage in minimal physical activity throughout the day. This could include activities like sitting at a desk, driving, or watching TV.
This value estimates your daily calorie needs if you engage in regular physical activity, such as exercise, sports, or manual labor. It accounts for a higher energy expenditure due to increased physical movement throughout the day.
After you have entered all the necessary information and selected your preferred calculation formula, the next step is to trigger the calculation of your energy expenditure results. This is done by clicking the "Calculate" button. Here's how to use it:
The "Calculate" button is located at the bottom of the form, after you have filled in your personal details and selected the desired formula for energy calculation. Once you've completed all the input fields, you can proceed by following these steps:
When you click the "Calculate" button, the calculator will automatically generate the following results:
The calculator will display these results in the respective fields for each value. Once the results are calculated, they will appear on the screen, and you can use them for diet planning, exercise adjustments, or other health-related goals.
If any fields are left empty or contain incorrect data, the calculator will not perform the calculation and will leave the result fields blank, allowing you to correct the input and try again.
Once you click the "Calculate" button, the calculator will process your inputs and display the results in the form of energy expenditure values. These results are essential in understanding your body's daily calorie requirements based on the selected formula. Below is a guide to interpreting the calculation results:
The calculator will provide the following key results:
These values help you understand how your body burns calories based on your lifestyle and activity levels. By analyzing these results, you can make informed decisions about your diet, exercise, and overall health management.
Energy expenditure is closely related to your activity level. Here’s how different levels of activity influence your energy needs:

The Expenditure and Energy Requirement Calculator is a tool designed to help you estimate your daily calorie needs based on your personal characteristics (weight, height, age, and gender) and activity level. It calculates your Total Energy Expenditure (TDEE) and provides specific recommendations for sedentary and active individuals.
To use the calculator, simply enter your weight, height, age, and gender. Then, select the energy calculation formula that best suits you. After filling in all the necessary fields, click the "Calculate" button, and the calculator will display your energy expenditure results.
The calculator provides three different formulas to choose from:
Total Energy Expenditure (TDEE) is the total number of calories your body needs each day to maintain its current weight. It includes your Basal Metabolic Rate (BMR) and the calories burned through physical activities. The calculator will estimate your TDEE based on your personal information and activity level.
Your activity level plays a crucial role in determining how many calories you need. The calculator provides results for both sedentary and active individuals. A sedentary lifestyle requires fewer calories, while a more active lifestyle increases your calorie needs due to higher energy expenditure from physical activity.
If you’re unsure about your activity level, think about your daily routine. If you mostly sit at a desk, walk around occasionally, or engage in minimal physical activity, you likely have a sedentary lifestyle. If you engage in regular exercise or have a physically demanding job, you may fall into the active category.
Yes, the calculator is a great starting point for setting up your diet and exercise plans. By understanding your energy requirements, you can adjust your calorie intake to meet your weight loss, maintenance, or muscle gain goals. To lose weight, aim for a calorie deficit (consume fewer calories than your TDEE), and to gain muscle, you may need a calorie surplus (consume more calories than your TDEE).
While the calculator provides helpful estimates for most individuals, it may not be suitable for those with specific medical conditions or unique dietary needs. For personalized advice, it’s always recommended to consult a healthcare professional or a registered dietitian.
The accuracy of the calculator depends on the quality of the data you enter and the formula you choose.
