I've been trying to stay under $600 a month for food for a couple of months now. I failed in June. But as of today, after one last $21.11 trip to Aldi, July looks good.
I know $600 probably sounds like a lot to some people. However the Maptitude map linked below shows average household food expenditure in NJ is $8109, or $675 a month. And the National Standards the IRS puts out (for figuring out how much delinquent taxpayers can afford to pay) says $646 for two people per month. I'll link to that page, too. And it's a lot lower than we have been spending.
Quicken tells me we averaged $718 a month from July 2017 through June 2018. It was probably higher than that because I've missed recording a lot of things during chaotic periods. Right now it says I should have $785 in cash! It's more like $50, and I'm sure a lot of that unknown spending was on food.
I've been using an app called Daily Budget on my phone. It tells me every day how much I can spend without getting too far ahead of myself during the month. It's designed to budget everything, but I'm only using it for food spending right now. It's been a big help. I found it after reading about a similar app someone came up with to help Food Stamp users spread their spending out more evenly over the month.
