Though a monthly budget is generally the most reasonable timeframe for which to set up an initial personal or household budget, there are many sources of income and expenses that do not perfectly follow a monthly schedule.For instance, you may receive a paycheck every week or two weeks, not once a month. In that case, you will want to calculate how that adds up over one month's time and write that in the appropriate row and column. You may also have certain expected or even recurring expenses that occur more or less often than monthly.
How to use your monthly budget worksheet. Below is a worksheet that attempts to list possible sources of monthly income as well as expenses.
