Yeah, no, I meant per week. My school has weird dining hall hours, including closing early on the weekends (often before my activities are finished) to “encourage us to explore Philadelphia restaurants” and only having 2 inconvenient halls open for breakfast. I usually end up spending most of my paycheck on breakfast, milk, and 2 dinners/week. Thanks to insurance, my medication is $20/month that I pay out of pocket. I also have an unfortunate comic book habit that eats away at some of the rest. As for fun stuff that costs money, I like weird bands that have cheap concert tickets (~$15-$25) and I buy hockey tix on StubHub the day before – center ice is usually $23.
Madison isn’t Philly so your spending habits will probably be different. If you’re into sports you’ll get student discounts (and women’s hockey, my all-time favorite, is only like $5/game to start with). Concerts are about the same price. Theater is cheaper than Philly. I know UW dining halls are kinda screwy so you’ll probably devote a bigger portion of your funds to that and personal care (toothpaste, shampoo, etc.)
