Baby Formula Calculator

Baby Formula Feeding Calculator

Estimate roughly how much formula your baby may need per day and per feed, based on weight and number of feeds.

This is a rough general estimate (about 150 ml per kg per day) for healthy full-term babies, for information only — not medical or feeding advice. Always follow your formula tin’s instructions and your paediatrician’s guidance, and feed responsively to your baby’s hunger cues.

How much formula by weight?

A common guide is roughly 150 ml of formula per kilogram of body weight per day, divided across feeds — but appetite varies day to day. Newborns feed little and often; older babies take more per feed and fewer feeds. Never force a baby to finish a bottle.
