How this is calculated
  1. Scoops per feed — from the official feeding chart for your baby's age.
  2. Daily grams = scoops × scoop weight × feeds per day.
  3. Total grams = daily grams × 7 days × weeks.
  4. Packages needed = total grams ÷ package size, rounded up.

All quantities above are based on zero spill/waste. For average real-world usage, add approximately 20% extra to account for typical spill and waste.

This estimate assumes that baby formula is your baby’s primary source of nutrition. It is based on standard packaging sizes, scoop measurements, and the manufacturer’s recommended feeding guidelines for each age. 

 


 

Unlike most formula calculators, our Formula Calculator includes an option to add extra formula for waste and spills. Based on our experience, we recommend using the 20% waste/spill setting when ordering. This accounts for common real-life factors such as spit-up, reflux, the one-hour time limit on prepared bottles, spilled feeds, and other minor losses.

 


 

For more details, you can find information on the Feeding Chart tab of each formula’s product page. If you have any further questions please feel free to contact our support team. (make this a link that opens a email to support@organicformulashop.com)

 


 

If you are supplementing with breast milk or introducing solid foods, your actual needs may be lower. Always follow your pediatrician’s advice for feeding guidance specific to your baby.
