The most important of these is automatic savings. Open a savings account, and set up your checking account so that you automatically transfer a set amount each month into your savings account. You don't have to transfer much money _ start with whatever your budget can afford. But making this automatic (and then resisting the urge to spend the money impulsively) will get you on the road to long_term savings.
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.
