I just have a monthly number for all expenses excluding rent and try to stick to it. It doesn't always work, but I kind of stay in the ballpark.

Thanks, but I've tried lots of more detailed ways of tracking before and decided this is just the one I prefer. My main concern is that I'm not overspending too badly and saving a good percentage for investments, and for that all I really need is a target spending number.
