Need to mix higher-calorie/fortified formula for your baby?

Use this tool to calculate how much water and formula powder to use based on feeding volume, desired caloric density, number of feeds that you want to mix, and any pump priming needs.

Note that this calculator assumes formula manufacturer instructions that call for 1 scoop of formula per 2 oz of water to make 20 cal/oz formula. Always check your formula label and consult your provider before making any changes.
