It's a tough question. If you retire at age 60, you could have one-third of your lifetime ahead of you, and still face substantial expenses. And you'll be living on a fixed income subject to inflation and taxation. Some of your requirements may be covered by a company or government pension. But only some.
Most people receive less, and the amount they do receive is fully taxed.
Unless you belong to a very generous plan, corporate pensions often fail to fill the void. See how much your income must grow by to meet the effects of inflation. Enter in your present income, a rate of inflation and the length of time to see the future equivalent of your current salary.
