So you set up your monthly budget with all of your standard expenses and that's great! But as we all know life is a lot of things but standard; and your standard budget isn't always going to cut it especially when the ad hoc expenses,as I call them, come knocking at your door. What’s an ad hoc expense? It’s an expense that is for a particular situation that does not occur every month. There are known ad hoc expenses such as birthdays, holidays, tax season, if you owe, that come around every year at the same time making them a li ttle easier to plan for. But there are also those unknown ad hoc expenses such as weddings, baby showers, housewarmings, graduations and any other celebratory gatherings that don't happen every year but will certainly have you dipping into that wallet.
