How to Use the Calorie Requirement Calculator
Using the Calorie Requirement Calculator is quick and straightforward. Just follow these steps:
- Enter Your Age
- Input your age in years.
- Calorie needs vary with age since metabolism slows down over time.
- Select Your Gender
- Choose male or female.
- Men typically require more calories due to higher muscle mass.
- Enter Your Height and Weight
- Provide accurate measurements in either metric or imperial units.
- This helps calculate your Basal Metabolic Rate (BMR).
- Choose Your Activity Level
- Sedentary (little or no exercise)
- Lightly active (light exercise 1–3 days/week)
- Moderately active (moderate exercise 3–5 days/week)
- Very active (hard exercise 6–7 days/week)
- Extra active (very hard exercise/physical job)
- Click Calculate
- The tool will instantly show your daily calorie requirement.
A Practical Example
Let’s say we have a 30-year-old female who is 5’6” (167 cm) tall, weighs 150 lbs (68 kg), and exercises moderately (3–5 days per week).
- Step 1: Enter Age = 30
- Step 2: Select Gender = Female
- Step 3: Enter Height = 167 cm
- Step 4: Enter Weight = 68 kg
- Step 5: Choose Activity Level = Moderately Active
- Step 6: Click Calculate
Result:
- Daily Calorie Requirement = ~2,150 calories
This means she needs around 2,150 calories per day to maintain her current weight. If she wanted to lose weight, she could aim for a calorie intake of about 1,650–1,750 calories per day. For weight gain, she would increase to around 2,400–2,600 calories.

Frequently Asked Questions (FAQ)
1. What is the Calorie Requirement Calculator?
It’s a tool that estimates how many calories you need daily to maintain your weight.
2. How does it calculate calories?
It uses your BMR (Basal Metabolic Rate) and multiplies it by your activity level to find your Total Daily Energy Expenditure (TDEE).
3. What is BMR?
BMR is the number of calories your body burns at rest to maintain basic functions like breathing and digestion.
4. What is TDEE?
TDEE is your total daily calorie burn, including activity and exercise.
5. Can I use this for weight loss?
Yes. Subtract 500–700 calories from your daily requirement to lose around 1–1.5 lbs per week.
6. Can I use it for weight gain?
Yes. Add 300–500 calories daily to promote healthy weight or muscle gain.
7. Does age affect calorie needs?
Yes. As you age, metabolism slows, so fewer calories are needed.
8. Why do men need more calories than women?
Men usually have more muscle mass, which burns more energy at rest.
9. Is this calculator accurate?
It provides a close estimate, but individual factors like genetics and metabolism can vary.
10. Can athletes rely on this?
Yes, but athletes with intense training may need additional adjustments.
11. What if my activity level changes?

No. It’s a helpful guide, but dieticians can provide tailored plans.
14. Can it help with medical conditions?
It’s not designed for medical purposes. Always consult a healthcare provider if you have specific conditions.
