Daily Formula Intake vs Baby Weight

Baby Formula Intake Estimation

Infants typically need about 2.5 ounces of formula per pound of body weight per day, with a maximum of about 32 oz/day.

Formula

Daily Intake (oz) = Baby Weight (lbs) x 2.5 (max 32 oz)

Monthly Cost = Daily oz / 2 (powder oz) x Cost per oz x 30 days

One ounce of powder typically makes 2 fluid ounces of formula. Always follow the specific mixing instructions on your formula brand.

Example Calculation

A 12 lb baby using formula that costs $1.20/oz of powder.

  1. 01Daily intake = 12 x 2.5 = 30 fl oz/day
  2. 02Feedings = ceil(30 / 4) = 8 feedings of ~3.75 oz each
  3. 03Powder needed = 30 / 2 = 15 oz powder/day
  4. 04Monthly cost = 15 x $1.20 x 30 = $540
