Traditionally, the bride's family foots the bill for the wedding ceremony and reception. If this is the route your family decides to take, a wedding can be an awfully big expense, so you want to be sure you're prepared! Many modern couples foot the bill of the wedding themselves, or they'll split the bill in some way with their families.
Whether your daughter is five or 15 years away from "I do," start saving now. Depending on how old your daughter is, it may seem too soon to be thinking about her wedding, but it'll be here before you know it. A great way to start saving is to open a separate account for her wedding fund and put away a set amount of money each month. This way, you can save a little at a time and not feel rushed.
If she's already engaged and you haven't been saving, don't panic. Evaluate your finances and determine how much you can afford to spend on the wedding. Once you've got that number, you can build the wedding budget.
