You might choose to break down your expenses even further, between things you need to have and things you want to have. For instance, if you drive to work every day, gasoline probably counts as a need. A monthly music subscription, however, may count as a want. This difference becomes important when it’s time to make adjustments.
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.
