Step One: Calculate Your After_Tax Income. Your after_tax income is what remains of your paycheck after taxes are taken out, such as state tax, local tax, income tax, Medicare, and Social Security. If you're an employee with a steady paycheck, your after_tax income should be easy to figure out. Look at your paystubs. If health care, retirement contributions, or any other deductions are taken out of your paycheck, add them back in.
An Example of the 50ቺተ Plan. Let's say your total take_home pay each month is ū귔. Using the 50┺┰ rule, you can spend no more than ũ껎 on your needs per month. You probably can't afford a ũ귔_a_month rent or mortgage payment, at least not unless your utilities, car payment, minimum credit card payments, insurance premiums, and other necessities of life don't exceed 趚 a month.
