Calorie Calculator for Children — How Much Energy Does Your Child Need Each Day?

A practical, professional tool to estimate your child’s daily energy needs based on age, sex, weight, height, and activity level — with an option to build a daily meal plan around the calorie target.

Based on established formulas For initial estimation Includes meal planning

How does it work?

In 3 simple steps, you get a daily calorie target and can start building a meal plan.

Step 1

Enter the details

Sex, age (manual entry or date of birth), weight, and height — just like in the dashboard.

Step 2

Choose the activity level

Sedentary / lightly active / active / extra active — based on real everyday life.

Step 3

Get the target + meal plan

The tool shows a daily target, and then you can build meals and track “consumed” versus “remaining”.

What does “activity level” mean, and how do you choose the right one?

Choose the option that fits most days, not just one unusual day.

Sedentary

Most of the day is spent sitting or on screens, with very little movement beyond a basic routine.

Lightly active

Daily walking or light play, with some movement here and there but no substantial exercise.

Active

Outdoor play, sports classes, long walks, or structured exercise several times a week.

Extra active

A child who is moving almost all the time, plus frequent intense sports or training.

Important tip

Tip: If you are unsure between two activity levels, choose the lower one. After a few days, you can compare the result with appetite and growth over time.

What will you get in the result?

A clear result that helps you quickly understand the target — and then use it in a practical way.

Frequently Asked Questions

Short answers to help you use the calculator correctly and understand the result more clearly.

Does this replace advice from a dietitian or doctor?
No. This is a tool for an initial estimate. If there is a sharp weight change, feeding difficulty, a medical condition, or any concern about growth, it is best to speak with a qualified healthcare professional.
How should I choose the activity level if I’m not sure?
Choose the level that fits most days. If you are between two options, start with the lower one and then compare the result with your child’s appetite, routine, and growth over time.
What should I do on sick days or during holidays?
On less active days, you can choose a lower activity level. That usually gives a result that better reflects the reality of that specific day.
How do I use the meal plan builder?
Add foods to each meal, and the tool will show how many calories have been consumed and how many are still remaining compared with the daily target. You can also reset a meal or clear the full plan.
Is the calorie target an exact number I must follow?
Not exactly. The result is an estimate, not a strict rule. Children’s appetite, growth rate, and daily needs naturally vary, so the target is best used as a practical guide rather than a fixed limit.
Important note Important: The calorie target is only an estimate. Appetite, needs, and growth patterns vary from child to child. Use the result as a helpful guide, not as a rigid goal.
