How Much Formula Should a Baby Drink Per Feed?
If you want the short answer, a common rough guide is about 150mL per kilo per day, then split across the number of feeds. That gives you a practical starting point, not a perfect rule for every baby.
The catch is babies are not robots. Appetite changes, growth spurts happen, and any feeding concerns should beat internet maths every time.

Worked example
A 5.5kg baby using a rough 150mL/kg/day guide lands around 825mL per day. Split across 6 feeds, that is about 138mL per feed.
Bottom line
Use the number as a starting point, not an argument. The calculator is there to make the prep maths less annoying.
