The most important part of keeping track of your finances is consistency. Regardless of which way you choose to log your transactions, you have to be able to refer back to them easily and reliably. Be sure to include important information like the date, amount spent or gained, and expense category with each entry. Also be sure to make your recording consistent. For example, you can record transactions as soon as they happen, every time you get home, or even once a week. Expense categories are an easy way to figure out what you spend the most money on. These categories may include things like housing, utilities, household expenses, groceries, health care, pets, personal expenses, and entertainment. These categories will of course vary from person to person and you can be as specific or general as you want with your categories. For example, you may simply want to record expenses as either need or wants. The important thing is that your categorizing is consistent between transactions. You can organize this notebook in several different ways. For simplicity. Alternately, you can treat it more like a logbook and record both your income and your expenses and how they affect the balance of your checking account.
