This Is a Risky Way to Plan Your Retirement

The most common age at which Americans retire is 63, and the age at which most retirees start collecting Social Security is 62 -- the earliest age at which they can do so. But personal finance guru Suze Orman has recently urged people to not retire until age 70: " 70 is the new retirement age -- not a month or year before."

With or without Ms. Orman's urging, many working Americans are already planning to work a long time: Fully 30% of 60-year-olds plan to work until at least age 70, according to a recent CareerBuilder survey. And among all workers, a significant 23% plan to work until at least age 70, per a Willis Towers Watson report. That can be a good plan, but it should not be your only plan -- or you risk having a very difficult retirement.

Here's a look at why it's smart to work until age 70 and why you shouldn't plan to.

Why working a few more years is a great idea

There are actually a lot of reasons why it's smart to not plan to retire early. Let us review a few:

  • The longer you work, the more you can sock away for retirement -- and the more powerfully it can grow.

  • The longer you work, the more you may be able to collect in 401(k) matching funds from your employer. That means more free money for your retirement war chest.

  • The longer you work, the shorter your retirement will be. Therefore your nest egg will have to support you for fewer years, and you may be able to withdraw more each year.

  • The longer you keep working, the longer you may be able to stay on your employer's health insurance plan, which can keep more money in your pocket.

  • The longer you delay retiring, the bigger your ultimate Social Security checks will be (though making them bigger will only be worth it if you live a longer-than-average life).

  • Since Social Security benefits are calculated based on your 35 highest-earning years (adjusted for inflation), you will either be getting closer to having 35 years' worth of income or you'll be adding some higher-earning years that will kick out lower-earning years, boosting your benefits.

The following table should help make it clear just how powerful it can be to add a few more years of saving and investing:
