About This Calculator
The Baby Formula Calculator helps parents and caregivers determine how much infant formula a baby needs each day based on their weight and feeding frequency. Whether you are exclusively formula feeding or supplementing breastfeeding, knowing the right amount ensures your baby gets adequate nutrition for healthy growth and development.
This calculator uses the standard pediatric guideline of 150 milliliters per kilogram of body weight per day, which is recommended for infants aged 5 days to 3 months by health authorities including the National Health and Medical Research Council of Australia and Stanford Children's Health. For newborns under 5 days, the recommendation is 30-60 ml/kg, and for older babies the amount adjusts to 120 ml/kg (3-6 months) and 100 ml/kg (6-12 months). The total daily amount is divided by the number of feedings to determine the volume per feeding.
Every baby is unique and has individual feeding needs. This calculator provides estimates based on population-level guidelines. Always follow your baby's hunger cues — look for signs like rooting, lip smacking, or sucking on hands. A well-fed baby will have 5-6 wet diapers daily after 5 days old, gain weight steadily, and meet developmental milestones. If you have concerns about your baby's feeding or growth, consult your pediatrician or a lactation consultant.

Frequently Asked Questions
How much formula should I give my baby per day?
The general guideline is 150 ml of formula per kilogram of body weight per day for infants aged 5 days to 3 months. Newborns (1-4 days) need 30-60 ml/kg, babies 3-6 months need 120 ml/kg, and babies 6-12 months need 100 ml/kg. Always consult your pediatrician for personalized advice.
How do I calculate baby formula per feeding?
Divide the total daily formula amount by the number of feedings per day. For example, if your baby needs 750 ml daily and feeds 8 times, each feeding should be approximately 94 ml (about 3.2 oz).
How often should I feed my baby formula?
Newborns typically feed 8-12 times per day (every 2-3 hours). At 1-2 months, feedings reduce to 6-8 times daily. By 4-6 months, most babies feed 5-6 times daily. Always follow your baby's hunger cues.
Can I overfeed my baby with formula?
Yes, overfeeding is possible. Signs include frequent spit-up, excessive weight gain, and fussiness after feeds. Follow the recommended amounts from the baby formula chart and consult your pediatrician if concerned.
How do I know if my baby is getting enough formula?
Signs your baby is well-fed: 5-6 wet diapers daily after 5 days old, steady weight gain, contentment after feeding, and meeting developmental milestones. Your pediatrician tracks growth on infant growth charts.
Should I wake my baby for formula feeds?
For newborns under 4 weeks, wake them if they sleep longer than 4 hours without feeding. After they regain birth weight and are growing well, you can let them sleep longer between feeds.
How much formula does a 3-month-old need?
A 3-month-old typically needs about 150 ml per kg of body weight daily, divided into 6-7 feedings. For a 6 kg baby, that is about 900 ml total, or roughly 130-150 ml per feeding.
What is the difference between formula feeding and breastfeeding amounts?
Formula-fed babies may need slightly more volume than breastfed babies because formula is less bioavailable. While breast milk changes composition to meet baby's needs, formula has a fixed composition, so serving sizes are more standardized.
