No matter how old you are right now, you should already be saving for retirement. Whether you’re contributing to a 401(k), IRA or other long-term investment (or all three), you have to make sure that you’ll have enough money to stop working and have enough money to last the rest of your life.
However, how will you know when you’ve reached a reasonable amount? How can you be sure that your nest egg will sustain your lifestyle during your golden years? Saving is a two-pronged approach: first, you need to put away enough while you’re employed.
