Formula Feeding Calculator
Calculate how much formula your baby needs by age and weight, with a daily schedule and monthly cost estimate.
Quick Answer
Most babies need about 2.5 oz of formula per pound of body weight per day, up to a max of 32 oz. A 10 lb baby needs roughly 25 oz/day. Feed on demand and look for hunger cues rather than strict schedules.

About This Tool
The Formula Feeding Calculator helps parents estimate daily formula intake, create a sample feeding schedule, and budget for monthly formula costs. It uses the standard guideline of 2.5 oz per pound of body weight per day, adjusted by age-appropriate feeding patterns.
The 2.5 oz Rule
Most pediatricians recommend 2.5 oz of formula per pound of body weight per day, up to a maximum of about 32 oz. This is a starting point — some babies need slightly more or less. Watch your baby's cues: turning away from the bottle, slowing down, or falling asleep all signal fullness.
Feeding on Demand vs. Schedule
While a schedule helps with planning, feeding on demand is generally recommended. Babies go through growth spurts where they need more, and quiet days where they need less. The schedule above is a guideline to help you prepare bottles, not a rigid requirement.
