Try to figure out how much you can realistically save between now and when you plan to have your wedding. Then, decide how much of that money you are willing to spend on the wedding as opposed to other expenses. Make sure to take all your expenses into account. This could include things like rent, groceries, cell phone bills, student loan payments, and transportation costs (e.g., gas money and car maintenance). Leave room in your budget for unexpected expenses, like medical bills or vehicle repair costs.
