Estimate the daily calories your child needs to support healthy growth, development, and an active lifestyle.
This tool helps parents understand how many calories their child needs each day to grow, learn, and stay active. Based on age, gender, weight, and activity level, it provides science-backed daily nutrition targets that align with WHO and CDC dietary guidelines. It's a useful tool for planning a healthy, balanced diet that fuels your child's development.
| Age Group | Estimated Daily Calories |
|---|---|
| Toddlers (2–3 years) | 1,000–1,400 |
| Kids (4–8 years) | 1,200–1,800 |
| Girls (9–13 years) | 1,600–2,200 |
| Boys (9–13 years) | 1,800–2,600 |
| Teens (14–18 years) | 2,000–3,200 |
This calculator provides an estimate. A child's appetite is often the best indicator of their needs. Focus on providing nutrient-dense foods and consult a pediatrician for personalized advice.
Children's energy needs are not just scaled-down adult numbers. Pediatric estimates add a growth component — the extra energy cost of building new tissue — on top of baseline metabolism and activity. That is why an active teenage boy can need as many calories as a grown man (up to ~3,200 per day), while a sedentary 4-year-old may need only ~1,200.
This calculator adjusts for age, sex, weight, and activity level using pediatric energy equations aligned with WHO and CDC guidance. Because children grow in spurts and plateaus rather than a straight line, treat the result as a flexible planning target — not a daily quota to hit exactly.

Estimates a child’s daily calorie requirement from age, sex, weight and activity level.
The calculator applies its age-, sex- and activity-specific energy-needs formula to the entered values. The calculation uses age, sex, weight and activity level.
Children’s energy needs change with growth, puberty, body size, activity and health status. Use the number as an estimate and consider professional advice when the result may affect health, treatment, pregnancy, nutrition, exercise safety or another important decision.
