That’s approximately $12/day/person. I figure $15/day/person.
But it’s gas, taxes and insurance that have been going up; much more so than foo.
I used to track household costs like this when I was off from work and my friend was going through a divorce... I was coming over to let his dogs out mid day... and eventually he just asked me to move in.
Our arrangement had me buying fuel oil, groceries and doing stuff around the property like cutting the lawn, cooking, cleaning, installing a custom designed HVAC control for moving hot air from the pelletstove in the basement den to the rest of the house... servicing the oil burner on the water heater... all sorta stuff.
Well I remember tracking costs and I had the groceries and dry goods provisioning down to about $11 per day for both of us... plus, we did a shitload of entertaining at the farmhouse... and my groceries covered that too.
Granted, sometimes he would not show up for dinner... but I was making good healthy homecooked meals (other than chili cheese fry night... hahahaha!)... but it was a lot of work. I was constantly checking all the circulars for the sale items... constantly cutting USEABLE coupons for staple items... and being extra frugal buying stuff like cheese ends from the deli department (perfect for Mac-N-Cheese), produce that had tiny imperfections... or the bagels in the bulk bins went from 89 cents each to $1.99/dozen at 8:30pm... I made good use of the 1967 chest freezer that cost him $60 to run until I defrosted it... which hadn’t been done in 20 years.
Anyways... $11/day for 2 guys plus weekend entertainment of a houseful of lady friends.
