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.
Lastly, if the numbers still aren’t adding up, you can look at adjusting your fixed expenses. Doing so will be much more difficult and require greater discipline, but on close inspection a "need" may just be a “hard to part with.” Such decisions come with big trade_offs, so make sure you carefully weigh your options. Tip: Small savings can add up to a lot of money, so don’t overlook the little stuff. You might be surprised at how much extra money you accumulate by making one minor adjustment at a time.
