The best way to make a budget for the future is to figure out how you spend your money now. First, look at where your money comes from and where it goes. Track all of your income and expenses for a month or two before creating your budget. You'll need to keep track of all of your purchases - from a cup of coffee to movie tickets - by writing them down in a notebook or holding on to receipts.
Write down how much you spend in each category every month. Don't forget to include money that you save each month to help you meet your future goals. Be realistic about your budget, so that it's easy for you to follow.
