This calculator will provide the amount of ounces or ml of formula a baby should receive per feeding based on weight. A formula feeding chart is also available to provide general recommendations.
How Much Formula To Feed A Baby
According to the American Association of Pediatrics, babies under 6 months of age should receive 2 1/2 ounces (or 75ml) of formula for every pound of body weight per day. These feeding guidelines can vary depending on each individual baby, so the AAP offers suggestions that let you know when a baby may need more or less.

How do I calculate how much formula my baby needs?
Based on the AAP’s recommendation, you would multiply your baby’s weight in in pounds times 2.5 or by 75 for kilograms. This will tell you how much your baby might drink for an entire day. For a six and one half pound baby, the formula would be 6.5 X 2.5. This equals 16.25 ounces.
