One 23-year-old Gen Zer told Business Insider by text that he spends about $130 for a week and a half on groceries. "Fancy sodas and drinks" and "random snacks at Trader Joe's" account for the bulk of the bill. He also said he spent about $35 on protein bars.
$660 a month on groceries is high but really not the issue. No mention of rent, healthcare, education (student loans) etc.
The typical American household now needs to spend $445 more on groceries a month to purchase the same amount of goods they were spending a year ago, according to a report from Moody's.
Not sure how you arrived at $660 a month.
$130 for a week and a half's worth of food, assuming it's $130 each subsequent week and a half of course, would be $346.67 a month.
I'm also assuming the $35 of protein bars is part of the $130 every 1.5 weeks.
If it's extra then that's $440 monthly.
