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.
Step Three: Limit Your "Wants" to 30 Percent. This sounds great on the surface. Can you put 30 percent of your money toward your wants? Hello, beautiful shoes, trip to Bali, salon haircuts, and Italian restaurants. Not so fast. Remember how strict we were with the definition of a "need"? Your "wants" don't include extravagances. They include the basic niceties of life that you enjoy, like that unlimited text messaging plan, your home's cable bill, and cosmetic (not mechanical) repairs to your car.
