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.
Step 1: Note your net income. The first step in creating a budget is to identify the amount of money you have coming in. Keep in mind, however, that it's easy to overestimate what you can afford if you think of your total salary as what you have to spend. Remember to subtract your deductions for Social Security, taxes, 401(k) and flexible spending account allocations when creating a budget worksheet. Your final take_home pay is called net income, and that is the number you should use when creating a budget.Tip: If you have a hobby or a talent, you may be able to find a way to supplement your income. Having an extra source of income can also be helpful if you ever lose your job.
