This is one of the biggest things that you need to do to create an effective budget. It helps if you have separate categories, particularly when it comes to fixed costs (rent, loans, etc.) vs changing costs (groceries, utilities, etc.). Break down everything that you have to pay for and designate a set amount for each. For your fixed costs, that should be easy since they pretty much stay the same. For the costs that are changing, set realistic budget amounts for each. For example, saying that you’re only going to spend $25 on groceries for the month isn’t a realistic goal (unless maybe you have a farm and garden). You can make it tight, but just make sure that it’s enough. If you don’t spend it all, then great! Whatever is leftover can go to savings or maybe an extra payment to a credit card.
