Sometimes a whole crate of birthday candles might not be enough.

Americans are living longer than ever, with the average life expectancy now rising to about 79 years. Some have referred to this trend as the “longevity revolution,” but it’s also creating a revolution in the way people think about retirement.

“What worked for retirees a generation ago isn’t going to work today,” says Jack Teboda, president of Teboda & Associates, a financial services firm.

“For most people, pensions are no more. Social Security has an uncertain future. And individual savings aren’t where they need to be for far too many people.”

That means people need to consider a number of factors to improve the odds of a joyful retirement. 

Teboda says just a few of the factors retirees need to be aware of are:

•    Tax implications. As people save for retirement, they often make plans based on the total amount in their accounts, but neglect to think about what kind of effect taxes will have on their bottom line. “Many retirees have money in tax-deferred vehicles, such as a traditional IRA or a 401(k).” “you were able to put off paying income taxes on the money while you were accumulating it, but once you are in retirement and start withdrawing money, it becomes taxable.”
•    Long-term care needs. When it comes to longevity, outliving your money isn’t the only concern. There’s also a greater chance that, as the decades pass, your health will decline and you’ll be in need of some sort of long-term care, which can be expensive.
•    Market risks and you. In general, the longer you invest the more potential your money has to grow, but not everyone has the same risk tolerance. An aggressive-investing approach that could pay off more in the long run can make some people nervous. One possibility is an annuity, which is an insurance product that pays the person a monthly amount for the rest of their lives, much like a pension.

“With a real possibility that retirement could last three decades or longer, you need to put yourself in the best financial position possible. “Anyone who doesn’t have a solid retirement plan and is just leaving things to chance could be making a very costly mistake.”
