I am terrible about groceries and food budget...so I will just kinda think out loud here.
I figure I spend about $600 a month on all things consumable (including paper products and dog food and kitty litter etc...and I figure all of that is about $100 a month) That leaves me $500 for food and there are 4 of us and an occasional guest.
So for breakfast they usually eat a piece of fruit, toast or cereal. We will budget for cereal since it is the most expensive. Almond milk is about $3 a carton and a box of cereal is about $2.50. So $8 a week for three girls. I usually have a protein bar or left overs so that's about $6 a week for me. So breakfast comes out to about $14 a week or $2 a day or $.50 per person a day.
girls get a sandwhich...usually p b and j. an apple. something crunchy and sweet. and a veg.
So a loaf of bread and a jar of pb and jelly, 15# of apples, a box of cookies or granola bars, and a couple pounds of baby carrots (right now they take cucumbers or cherry tomatoes which are free).
$2.50 $5 $2 $15 $5 $2 = about $30 or $10 a week each girl or about $1.50 a day
i suck and spend about $4 a day at work but eat leftovers on my days off. So $20 or average about $3 a day which brings our daily lunch total to $4.50
Supper is our most expensive meal. I get a good deal on meat at work. The all natural angus roast in the pot right now was $1 per pound (heck yeah!!!) I added a little bullion and onion soup mix to cover up the freezer burn (yeah well....) and some celery tops and carrots. So $3 for the meat and about $.50 worth of carrots. $1 for the seasonings. Potatoes will be about $2 and I will serve some sliced tomatos and cucumbers with it and perhaps some fried zucchini (veggies from the garden)...so maybe $.25 for oil. total for awesome supper that does not happen often is $6.75 and this is a big dinner! I only cook like this maybe 1 time a week. but we will go with it because it i the most I will spend on a meal if I actually plan a little.
Bottom would be speghetti or chili or soup. average cost is about $4 for the meal if it includes salad or bread. So average I would say $6 per night.
and of course it would be silly not to figure in snacks, treats etc....so lets just say we spend $3 a day on that stuff.
that brings us to $14 a day....or about $100 a week. or about $450 a month. Plus there is the occasional celebrations, snacks for teams and classes etc.
There are four of us and my kids ages are 8, 11, and 15. So everyone is eating adult portions.
