Step 2: Track your spending. It’s helpful to keep track of and categorize your spending so you know where you can make adjustments. Doing so will help you identify what you are spending the most money on and where it might be easiest to cut back. Begin by listing all your fixed expenses. These are regular monthly bills such as rent or mortgage, utilities or car payments. It’s unlikely you’ll be able to cut back on these, but knowing how much of your monthly income they take up can be helpful.
Step Two: Limit Your Needs to 50 Percent of Your After_Tax Income. Now go back to your budget. How much do you spend on "needs" each month, things like groceries, housing, utilities, health insurance, car payment, and car insurance? According to Warren and Tyagi and their 50ቺተ rule, the amount that you spend on these things should total no more than 50 percent of your after_tax pay.
