If you are tracking your spending (and you really should…there are many choices for OSS finance software out there…), it is easy to pull a report and say, “I’ve spent $4,554.96 on groceries so far this year. Holy crap that is a lot!”
Another way to look at it is the opportunity cost or what you would have spent on an equivalent product, say if you had outsourced the product. In this case the product is groceries (whether from a grocery store, 7-11, local bodega, or from your local dairy. So with the above amount, I spent roughly $4,555 over 105 days, which equates to $43 a day and just under $9 per person in my family. All for mostly organic, whole foods (don’t look on the top shelf).
Hope you did your taxes.
