Most of us want to live to 100. Wait until you hear how much that retirement costs.

With all the aches and pains that attend old age, how many Americans would really want to live to 100?

A lot of us, it turns out.

More than half of Americans, 54%, say it is their goal to live to 100, according to a new report from Corebridge Financial, a financial services company.

Much of the rest of the 20-page report deals with what it costs to live for a century.

And that, experts say, is where the numbers get scary.

“If we live till 100 and we retire at 65, we have 35 years of retirement that we need to finance,” said Lina Walker, senior vice president of global thought leadership at AARP.

A 38-year retirement? What it costs to live to 100

Here’s the math:

As a rule of thumb, financial planners say we should expect to spend about 80% of our working income in retirement. With the nation’s median household income at $74,580, according to the census, the typical family might need about $60,000 a year in retirement money.

The average American retires at 62. If you live to 100, that means 38 years of retirement. At $60,000 a year, that works out to a retirement budget of about $2.3 million.

Social Security income will cover at least some of those costs. Even so, it’s a lot of money. In the Corebridge survey, only 27% of respondents said they are confident they won’t outlive their retirement savings.

In fact, two-thirds of those surveyed said they fear running out of money more than they fear death itself.

The findings draw from a 2023 survey of 2,284 adults by Morning Consult.

How many of us will live to 100?

Will half of us make it to 100? Probably not. Yet, the ranks of centenarians are growing.

The number of Americans ages 100 and older is forecast to more than quadruple to 422,000 by 2054, according to census figures analyzed by Pew Research.

The number of centenarians alive today, about 101,000, is nearly triple the number who were alive in 1990.

“While it’s impossible to say whether an individual person will live to 100 – we don’t have a crystal ball – some demographic groups are especially likely to reach that milestone,” said Katherine Schaeffer, a research analyst at Pew.

Of all centenarians alive today, Schaeffer said, 78% are women, and 77% are white.

Retirement experts fear many future centenarians will exhaust their retirement money long before they take their last breath.

“Millions of Americans are at risk of outliving their savings,” said Catherine Collinson, CEO of the Transamerica Center for Retirement Studies. “That impacts their own household, their own health, their well-being and their longevity. It puts a strain on their families.”
