I have an allowance

Each month, my husband and I get an allowance. I don’t pull it out in cash, it just gets calculated on a spread sheet, but its there. One of the hard things for people- especially couples – who use an allowance system is determining what comes out of the allowance and what doesn’t. Like any of the decisions people make about their personal finances, I’m not certain that there is a right or wrong answer. There just has to be an understanding of what it means.
In our case, when we went to the allowance system, we talked about what we expected it to cover when we talked about how much we would each get. That’s right, we get different amounts. I get $50 more per month than he does. This is not because I’m the sole earner, but because I have a professional appearance (well, business casual) that I need to maintain.
Here’s a basic list of what comes out of our allowances:
Movies
New clothes
Haircuts & other personal grooming
Books
Domain registration fees (we each have our own domain)
Individual eating out
Video games/subscription fees
Here are a couple things that don’t come out of our allowances:
Eating out together (this has its own line item)
Netflix subscription (treated like a monthly bill)
But sometimes things come up that aren’t quite clear. And in those cases, we discuss. For example, I am considering joining a professional organization for my field. The husband does not believe that the fees for joining or taking their certification tests should come out of my allowance. His reasoning behind that is that this is something I am doing for professional development, kind of like going to school, and shouldn’t cut into my spending money.
On the same theory, if he ever goes back in to the work force, he will likely need a new wardrobe. Having been unemployed (now a student) for 2+ years and before that working for a company where jeans and t-shirts were the norm, he pretty much as one nice interview outfit. If he were to get a job in a business casual or business environment, he would need a whole new wardrobe, not just a piece here and there to replace old items. In that case, we would set a budget completely separate from his allowance to spend on new clothes. If he went over that amount, then it would come out of allowance.
The same would go for me if I were to move out of business casual into a business/professional environment.
However, I also run a weekly/monthly micro-fiction contest. The money for that domain and the prizes I give out comes from my allowance. I have edited and published one vanity micro-fiction book and hope to be doing another one in the near future. Costs for that will also come out of my allowance.
My reasoning for that is that while I would love to make enough money off my writing to pay the bills, I don’t. In fact, it costs us money. Since this is my hobby, much the way video games are his hobby, it comes out of allowance.
In the end, our determination of what is allowance and what isn’t comes from the determination of whether or not something is for the good of the whole family (there are only two of us, but still) or just one person.
Its not a perfect system by any means, but that’s okay, because the important part is that it is always up for discussion.
Do you use an allowance system? How do you decide if something comes from your allowance or another part of the budget?
