I live in the Upper Midwest, in the metro area of Minneapolis/St. Paul. Prices can vary quite a bit even between different cities in our metro area!
I paid $3.29 for gas this morning. My car is actually a small SUV (Hyundai Tucson), is a 2006 model, bought 2 years ago and cost about $12,000. I think my interest rate is about 7% for that.
DH and I have a 3 bedroom/3 bath/2 car attached garage house, 1500 sq ft, built in 1981. We bought it for $200,000 about 4 years ago. It's now worth about $170,000 due to dropping real estate! We just refinanced, and our payment will be going down to about $1200, including property taxes and homeowner's insurance. We have forced air central heating and air-conditioning. In the summer our electrical bill is about $70 and our gas bill is about $30. It's reversed in the winter, as our furnace is gas.
DH and I both attended a private college. When we attended, tuition was $25,000 per year our freshman year. I think room and board tacked on another $5,000 or so to that price. That was 1999. This year, tuition at the same college for a freshman is $37,000, plus room and board. I just graduated from my master's program at a private university, and paid about $35,000 over the course of 5.5 years for that. My first set of student loans came due just now, and I'll be paying about $400 a month for the next ten years on that money. My company picked up the other $16,000 of the tuition. Sadly, it would have been even more expensive had I gone to the program offered by our state university.
I pay about $180 per month for my health insurance, which is through my employer.
I'd say I spend about $300 a month on groceries, but that's unusual. DH works for a chain of upscale grocery stores, and so we shop there. We could probably cut our grocery bill by a 1/3 if I shopped elsewhere.
We paid $8 per person for matinee tickets to the movies last time we went.
A paperback book costs about $8, a hardback costs about $25 - $30.
