Online Calorie Calculator: Estimate Your Daily Calorie Needs
Calorie Calculator
If you’re a Cookout fast food lover and also want to stay mindful of your health, it’s important to know the calories in your food. To help with this, we have a calorie calculator.
This calorie calculator helps you determine how many calories you need per day based on your age, weight, height, gender, and activity level. You can estimate your Total Daily Energy Expenditure (TDEE) and adjust your diet for weight loss, maintenance, or muscle gain by inputting your details.
How This Calorie Calculator Works
This calculator uses the Harris-Benedict Equation to estimate your Basal Metabolic Rate (BMR)—the number of calories your body burns at rest. It then multiplies BMR by your activity level to determine your TDEE.
Step 1: Enter Your Information
- Age (years) – Your body’s calorie needs decrease with age.
- Weight (kg) – Heavier individuals require more energy.
- Height (Feet) – Height is converted to centimeters for accurate calculations.
- Gender – Men generally have a higher BMR than women due to muscle mass differences.
- Activity Level – Choose from sedentary to super active based on your lifestyle.
Step 2: Calculate BMR
The Harris-Benedict Equation is used for BMR calculation:
- For men: BMR=88.362+(13.397×weight in kg)+(4.799×height in cm)−(5.677×age)BMR = 88.362 + (13.397 \times \text{weight in kg}) + (4.799 \times \text{height in cm}) – (5.677 \times \text{age})
- For women: BMR=447.593+(9.247×weight in kg)+(3.098×height in cm)−(4.330×age)BMR = 447.593 + (9.247 \times \text{weight in kg}) + (3.098 \times \text{height in cm}) – (4.330 \times \text{age})
Step 3: Multiply by Activity Level
| Activity Level | Multiplier | Description |
|---|---|---|
| Sedentary | 1.2 | Little to no exercise |
| Lightly Active | 1.375 | Light exercise (1–3 days/week) |
| Moderately Active | 1.55 | Moderate exercise (3–5 days/week) |
| Very Active | 1.725 | Intense exercise (6–7 days/week) |
| Super Active | 1.9 | Very intense exercise or physical job |
Step 4: Display Results
After clicking “Calculate Calories,” the script multiplies your BMR by your activity level to estimate your daily calorie needs.
Example Calculation
A 25-year-old woman, weighing 65 kg, 5 feet 6 inches (167 cm) tall, and moderately active (1.55 multiplier):
- BMR Calculation: 447.593+(9.247×65)+(3.098×167)−(4.330×25)=1,449.7 kcal447.593 + (9.247 \times 65) + (3.098 \times 167) – (4.330 \times 25) = 1,449.7 \text{ kcal}
- TDEE Calculation: 1,449.7×1.55=2,247 kcal/day1,449.7 \times 1.55 = 2,247 \text{ kcal/day}

FAQs about the Online Calorie Calculator:
1. What is the purpose of this Calorie Calculator?
This Calorie Calculator helps estimate the number of daily calories you need based on your age, weight, height, gender, and activity level. It uses the Harris-Benedict Equation to calculate your Basal Metabolic Rate (BMR) and adjusts it according to your activity level to determine total calorie requirements.
2. What information do I need to use this Calorie Calculator?
To use this calculator, you need to provide your age, weight (in kilograms), height (in feet), gender, and activity level. This information allows the calculator to estimate your daily caloric needs.
3. How do I calculate my daily calorie requirements?
After entering your information, click the “Calculate Calories” button. The calculator will apply the Harris-Benedict Equation to estimate your BMR and multiply it by your activity level to determine your daily calorie needs.
4. What are the different activity levels in the calculator?
The activity levels in the calculator are as follows:
- Sedentary (little to no exercise)
- Lightly active (light exercise or sports 1-3 days per week)
- Moderately active (moderate exercise or sports 3-5 days per week)
- Very active (hard exercise or sports 6-7 days per week)
- Super active (very hard exercise and a physical job)
5. How does the calculator determine the daily calorie requirements?
The calculator uses the Harris-Benedict Equation, which takes into account your weight, height, age, gender, and activity level to estimate the calories needed to maintain your current weight.
6. Can I use the calculator for both males and females?
Yes, the calculator works for both males and females. It adjusts the formula based on your gender to provide a more accurate estimate of your daily calorie needs.
