Formula calculator

A reference range for how much formula to offer, per day and per feed, from your baby's age and weight. It's a starting point — not a target — and always defers to your pediatrician.

A starting estimate — not a target to hit.

Before you use this number

  • This is general information, not medical advice. Always follow your pediatrician's guidance.
  • Feed responsively: the number is a guide, not a target. Follow hunger and fullness cues.
  • Never force your baby to finish a bottle.
  • The real signs your baby is getting enough are weight gain, wet nappies, and a content baby — not hitting a number.
  • Never exceed ~960 ml (32 oz) of formula per day; if your baby seems to want more, see your pediatrician.
  • Always prepare formula exactly as the tin says — wrong dilution is dangerous.
  • Not for: preterm/low-birth-weight babies, any medical condition, breastfed/mixed-fed babies, or over 6 months.
