How Safe Is Social Security?

A majority of Americans -- 54% -- are worried about not having enough money in retirement, according to a 2017 survey by Gallup. Social Security, designed to replace about 40% of pre-retirement income for average earners, will be a major help for most retirees. Indeed, the majority of elderly beneficiaries get 50% or more of their income from Social Security, while 23% of married elderly beneficiaries and 43% of unmarried ones get fully 90% or more of their income from it, per the Social Security Administration.

Given all that, it's no surprise that many people wonder just how safe Social Security is.

When it comes to how safe Social Security is, there's both good and bad news. First, though, here's a bit of background information on this critical program.

Meet Social Security and its trust fund

Social Security pays close to 62 million Americans, with benefits totaling $955 billion in 2017. About 42 million recipients are retirees collecting retirement benefits (others are dependents of those retirees, disabled workers and their dependents, and survivors, including children).

Here's how Social Security works: As you might have noticed on your paycheck, workers get 6.2% of their wages withheld as a Social Security tax. What many don't realize, though, is that their employers cough up a corresponding 6.2%, for a total 12.4% tax on earnings. (Unfortunately, those who are self-employed have to pay both the employer and employee portions, forking over the entire 12.4% on their own.)

Some people assume that the money they pay into Social Security goes into an investment account with their name on it, growing until they're paid from it in retirement, but that's not how it works. Instead, the money that you and about 167 million other people pay into the Social Security system is used to pay the benefits owed to current beneficiaries. For a long time now, there has been more money coming in than going out, so the process proceeded smoothly, with the surplus funds going into the Social Security trust fund.

The "Social Security trust fund" term actually encompasses two funds: The Old-Age and Survivors Insurance (OASI) Trust Fund and the Disability Insurance (DI) Trust Fund. Managed by the Department of the Treasury, they permit our government to contain assets collected and to keep track of inflows and outflows. There's a board of trustees who watch over the trust funds and who report to Congress annually on their condition. By law, funds are spent only on benefits and administration, and assets in the funds are invested only in securities guaranteed by the U.S. government. The Treasury makes "special issues" available solely for the trust funds. They differ from traditional marketable Treasury securities by being less vulnerable to changes in value due to overall market conditions. In other words, these investments are structured so that they never lose value. They generate interest that can be used to pay benefits and they can be redeemed or sold over time, too.
