My family of four (2 adults, a tween & a teen) living in the southern United States has spent $1,072 on average every month this year for groceries, with the lowest month being $886 and the highest being $1,337. That's up from an average of $1015 per month in 2022. Note this is groceries only; we average an additional $662 each month eating at restaurants.

I have been tracking my spending with an Excel spreadsheet for the past 20 years, but I think tools like YNAB and Dave Ramsey's Everydollar are fine for those who like them.
