Start keeping an expense tracker right away. By the time the 6th rolls around, you should know how much money you have in the back, even if all of the transactions haven't processed yet. At that time, you'll track how much you have in your account and then add in your income and you'll budget for all of it together. The easiest thing for many is to create a zero based budget, so at the end of the time period, you don't have money leftover and you start fresh with the new paycheck. Of course, there might still be some extra leftover and you might want to move things around, but it's definitely the easiest way to track and budget.
