Child Weight Growth Calculator

This is a tool to estimate your child’s weight based on their birth weight and current age in months. It assumes a growth rate of 0.5 kg per month.

Child weight Growth calculator formula

There are different growth weight formulas that can be used to estimate a child’s weight based on their birth weight and current age in months. One commonly used formula is the following:

Estimated weight = Birth weight + (Age in months x average monthly weight gain)

Monthly weight gain estimates based on child age

The average monthly weight gain can vary depending on the child’s age. Here are some rough estimates:

– Infants (0-12 months): 150-200 grams per week or 0.6-0.8 kilograms per month.

– Toddlers (12-24 months): 75-150 grams per week or 0.3-0.6 kilograms per month.

– Preschoolers (2-5 years): 50-75 grams per week or 0.2-0.3 kilograms per month.

Please note that these are approximate values, and actual weight gain can vary among children. It’s important to consult with your child’s pediatrician for more accurate and personalized information based on your child’s specific growth pattern and any individual factors that may affect their weight gain.

Weight Growth example

Using this formula, you can estimate your child’s weight at a given age by substituting the values into the equation. For example, if your child’s birth weight was 3 kilograms and they are now 10 months old, assuming an average monthly weight gain of 0.7 kilograms:

Estimated weight = 3 kg + (10 months x 0.5 kg/month)

Estimated weight = 3 kg + 5 kg

Estimated weight = 8 kg

Important note

Remember that this is just an estimation, and individual growth patterns may vary. Regularly tracking your child’s weight and consulting with their healthcare provider will provide a more accurate assessment of their growth.
