Child Calorie Calculator

Calories Needed: 0 calories per day

Maintaining a healthy diet is crucial for a child’s growth and development. To ensure they are getting the right amount of calories, it’s important to calculate their daily calorie needs. This Child Calorie Calculator simplifies the process, helping you determine the appropriate calorie intake for your child based on their age, weight, height, and activity level.

Formula The formula used in this calculator is based on the Harris-Benedict equation, which calculates the Basal Metabolic Rate (BMR) and then adjusts it according to the child’s activity level. The formula can be summarized as follows:

  • For boys: Calories Needed = 10 * weight (in kg) + 6.25 * height (in cm) – 5 * age (in years) + 5
  • For girls: Calories Needed = 10 * weight (in kg) + 6.25 * height (in cm) – 5 * age (in years) – 161

The result is then multiplied by the child’s chosen activity level to determine their daily calorie needs.

How to Use Using the Child Calorie Calculator is simple. Just input your child’s age, weight, and height. Then, choose their activity level from the drop-down menu, and click the “Calculate” button. The calculator will instantly display the estimated daily calorie needs for your child.

Example Suppose you have a 10-year-old girl who weighs 30 kg, is 140 cm tall, and has a moderately active lifestyle (activity level of 1.55). After inputting these values and clicking “Calculate,” you’ll find that her daily calorie needs are approximately 1741 calories.


  1. What is a child’s Basal Metabolic Rate (BMR)? BMR is the number of calories a child’s body needs to maintain basic functions at rest, like breathing and digestion.
  2. Why is the child’s activity level important in the calculation? Activity level affects the total daily calorie needs. More active children require more calories.
  3. Is this calculator suitable for all children? This calculator is designed for generally healthy children. If your child has special dietary needs, consult a healthcare professional.
  4. Can I use this calculator for infants and toddlers? No, this calculator is intended for children older than 2 years. Infants and toddlers have different calorie requirements.
  5. How accurate is this calculator? The calculator provides a reasonable estimate, but individual variations exist. Consult a nutritionist for precise guidance.
  6. Should I strictly follow the calorie recommendation? The calculated value is a guideline. Monitor your child’s growth and consult a healthcare provider for adjustments.
  7. What factors can affect a child’s calorie needs? Genetics, growth spurts, and underlying health conditions can influence calorie requirements.
  8. Can this calculator help with weight management? It can be a useful tool, but remember that overall health includes a balanced diet and physical activity.
  9. Is this calculator suitable for teenagers as well? While designed for children, it can be used for teenagers; however, more complex equations exist for adults.
  10. Why do the calorie needs differ for boys and girls? The formula takes into account gender-based variations in metabolism.

Conclusion Ensuring that your child receives the right amount of calories is an essential part of promoting their growth and well-being. Our Child Calorie Calculator simplifies the process of determining daily calorie needs, making it easier for parents and caregivers to plan nutritious meals. Remember that this is just a guideline, and individual needs may vary. Always prioritize a balanced diet and consult with a healthcare professional if you have concerns about your child’s nutrition.
