How much does baby formula cost for a month?

From 3-6 Months,your infant is entirely dependent on Formula.Hence the consumption would be max..on an average a good branded formula would cost anything bw 18-22 $ per can.So you would be requiring around 10 such cans for the month ( Based on personal experience),this may change depending on an infants consumption.Now my infant is 8 month old & has started eating solid foods,so the consumption of formula is only 5 cans a month.

Hope this is helpful.
