Cost is the part of this conversation most people don't even talk about, so I will. Sorority dues vary wildly by school. If you are looking at a big SEC school or a major private university, your dues are expensive. If you are looking at a smaller D1 or below, your dues can actually be pretty reasonable for what you get. The amount varies wildly and you should know what the range looks like before you make any decisions about whether this is financially possible.
A few things every girl walking in without a sorority mom should know before recruitment week.
Most sororities have payment plan options. You do not have to pay everything up front. Ask them during recruitment. It is not a rude question. Chapters are trained on how to answer it.
Sororities fall into two cost structures, and it's important to know about. Some are all-in, where you pay one large fee per semester and it covers your meals, your t-shirts, your sisterhood events, basically everything. Others are what I call "a la carte", where you pay a flat dues fee and then have to pay separately for every t-shirt, every date party, every event. The all-in chapters are sometimes more expensive on the front end and cheaper in total. The a la carte chapters can look cheaper at first and add up to more. Knowing which structure a chapter uses is one of the most important pieces of information you can collect during recruitment.
Your campus Panhellenic website often publishes dues for every chapter on campus. Go look. You will get a much clearer picture of cost from twenty minutes on that website than from any general post about sorority dues. It is public information. Use it.
There are one-time fees on top of regular dues. A pledge pin fee. A badge fee when you get initiated. The occasional fundraising minimum, or required shirt. None of them are individually huge, but they exist, and you should not be surprised by them.
Dues and housing are the two biggest costs, and housing varies depending on whether you live in the chapter house or out. Some campuses require sophomores to live in. Some do not have houses at all. Ask.
The last thing I want to say on cost. There are sorority sisters in every chapter who are stretched financially, who are on payment plans, who borrow clothes for events instead of buying, who pass on the optional trips. Nobody talks about it during recruitment because nobody talks about money in this country during anything. But once you are in, sisters lend formal dresses. They share game-day shirts. Sisters help each other figure out what is required and what is optional. This is all completely normal.
Asking about dues during recruitment is not rude. Pretending you don’t have a budget is the only thing that hurts you here.
