What is a Maintenance Calorie Calculator?
A Maintenance Calorie Calculator is an online tool designed to estimate the number of calories you need to consume daily to maintain your current weight.
It calculates you daily calorie needs based on your gender, age, weight, height, and physical activity levels.
By knowing your maintenance calories, you can manage your diet effectively for weight management or other fitness goals.
How to Use the Maintenance Calorie Calculator?
Follow these simple steps to calculate the calories you need daily to maintain your weight:
1. Select Gender: Choose your gender, male or female to get gender-specific
results.
2. Enter Age: Enter your current age in years.
3. Input Height: Select your height using feet and inches or by entering in
centimeters.
4. Input Weight: Enter your weight in pounds (lb.) or kilograms (kg).
5. Select Activity Level:
- Sedentary: Little to no exercise.
- Lightly Active: Light exercise or sports 1-3 days a week.
- Moderately Active: Moderate exercise or sports 3-5 days a week.
- Very Active: Hard exercise 6-7 days a week.
- Extra Active: Very hard exercise, physical job, or training twice a day.
6. Click Calculate: After entering all details, hit the "Calculate" button to get your result instantly.
7. View Results: The results will show the calories needed to maintain your
current weight.
This tool uses the Harris-Benedict equation to determine your basal metabolic rate (BMR), then adjusted based on your activity level to provide a maintenance calorie estimate.
Example of Results
Once you calculate, you’ll get a result like:
- Maintenance Calories: 2395 Calories per day (kcal/day)
- This means you should consume approximately 2395 Calories daily to maintain your weight.
How It Works With Formula
The Maintenance Calorie Calculator estimates the calories required to maintain your current weight using the Revised Harris-Benedict Equation.
This equation calculates your Basal Metabolic Rate (BMR), which is then multiplied by an activity factor based on your physical activity level.
How to Use the Formula
To calculate your maintenance calories:
- Calculate your BMR using the Harris-Benedict equation.
- Multiply your BMR by the appropriate activity factor based on your daily physical activity level.
- The result is your daily calorie intake needed to maintain your current weight.
Revised Harris-Benedict Equation
For Men:
BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) - (5.677 x age in years)
For Women:
BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) - (4.330 x age in years)
Activity Factor
After calculating your BMR, the result is multiplied by an activity factor based on your daily activity level:
| Activity Level | Description | Multiplier |
|---|---|---|
| Sedentary | Little or no exercise | 1.2 |
| Lightly Active | Light exercise or sports 1-3 days a week | 1.375 |
| Moderately Active | Moderate exercise or sports 3-5 days a week | 1.55 |
| Very Active | Hard exercise or sports 6-7 days a week | 1.725 |
| Extra Active | Very hard exercise, physical job, or training twice a day | 1.9 |
Example Calculation
Let's calculate the BMR for a 35-year-old man who weighs 80 kg and is 180 cm tall:
BMR = 88.362 + (13.397 x 80) + (4.799 x 180) - (5.677 x 35)
BMR = 1825.25 kcal/day
This means that the man's body requires approximately 1825.25 calories daily to perform basic functions at rest.
