You’d Probably Do Better Investing Your Social Security Taxes Yourself — Here’s Why It’s Still Worth It

Here’s a number that should stop you cold.

If you’d taken the Social Security taxes pulled from every paycheck and invested them yourself, you’d very likely retire with more money than Social Security will ever pay you back.

I’m a CPA. I’ve run this math, and most of the time, that statement holds up.

So why would I still tell you to keep paying in? Stick with me, because the answer is worth real money.

The myth you’ve been telling yourself

You’ve probably said it, or heard a neighbor say it: “I paid into Social Security my whole life. I’m just getting my own money back.”

On the surface, the numbers seem to back you up. By one common measure, most retirees collect far more than they contributed. The Committee for a Responsible Federal Budget figures a typical worker retiring in 2027 will draw around $730,000 in lifetime benefits after paying under $200,000 in taxes.

Sounds like the deal of the century, right?

It isn’t. That comparison ignores the most important idea in all of finance: A dollar you handed over at 25 is worth far more than a dollar handed back to you at 70. You gave up decades of growth on that money.

What happens when you count time

Once you adjust for that lost time, the “great deal” mostly evaporates.

The Urban Institute did exactly that, valuing lifetime benefits and taxes in today’s dollars. For a single, average-earning man turning 65 in 2025, the numbers are almost a dead heat: roughly $414,000 in lifetime Social Security benefits against about $412,000 in taxes paid.

Break even. That’s it.

Lower earners still come out ahead, thanks to a benefit formula tilted in their favor. A low-earning man in that group gets back about $251,000 on $185,000 paid.

But higher earners actually lose. That same analysis shows a high-earning man collecting around $547,000 after paying $659,000 in. He’s more than $100,000 in the hole.

Put plainly: Measured honestly, Social Security pays a real return of only about 1% to 2% a year for average and higher earners. That’s the number the “I’m just getting my money back” crowd never mentions.

So yes, you’d probably beat it yourself

Now line that up against the stock market.

Over the long haul, the S&P 500 has returned about 10% a year, according to Fidelity. Let’s be conservative and call it 8%.

Your share of the Social Security tax is 6.2% of your pay. Your employer kicks in a matching 6.2%, though economists will tell you that half really comes out of your wages too.

Invest just your own 6.2% at 8% across a 45-year career, and a middle-income worker could build a pot well into the seven figures.

Compare that to a Social Security return of 1% or 2%, and it’s no contest. In pure dollars, self-investing wins for most workers, and it wins big for higher earners.

It’s the same instinct behind claiming your check early to invest the difference, a move I’ve picked apart before. The spreadsheet looks seductive.

So I’ve just spent several paragraphs arguing against Social Security. Here’s where I turn around.

Why it’s still worth every dollar

That whole comparison has a fatal flaw. It treats Social Security like an investment. It isn’t one. It’s insurance. And it covers risks no 8% spreadsheet can touch.

Here are five things your private portfolio can’t promise you:

1. A check that never runs out. The market doesn’t care how long you live. Social Security keeps paying until the day you die, whether that’s at 71 or 101. About a third of today’s 65-year-olds will reach 90. Your own savings can run dry. This can’t.
2. A raise every year for inflation. Benefits rise with the cost of living, automatically — and the 2027 raise is getting bigger. Try buying that protection on the open market and see what it costs you.
3. Zero market risk. Picture retiring in 2008 with your “smarter” portfolio down 40%. Social Security doesn’t have bad years. It never shows up lighter because the Nasdaq sneezed.
4. A backstop if you get hurt. That same tax buys disability coverage. Get sidelined before retirement and your private plan just stops growing. Social Security steps in.
5. A safety net for your family. If you die, your spouse and kids can collect survivor benefits, one of the program’s most overlooked features. Your brokerage account offers no such thing.

Add those up and you’re not looking at a lousy investment. You’re looking at the cheapest longevity, inflation, disability, and survivor insurance you will ever own.

The bottom line

No company on Earth will sell you a lifetime, inflation-proof, crash-proof, family-protecting income stream for what Social Security charges.

Could you earn a higher raw return in the market? Absolutely. But you’d be taking on every ounce of the risk that Social Security quietly absorbs for you.

You’ve probably heard benefits could shrink, and it’s worth understanding. If Congress does nothing, the retirement trust fund is projected to run short around 2032, which would automatically trim benefits by roughly 22%.

But that’s a possibility, not a certainty. Lawmakers have faced this cliff before and always blinked. No politician wants to explain a benefit cut to 70 million voters.

Even in that worst case, the insurance is still a bargain.

So here’s the move: Don’t think of Social Security as your retirement plan, and don’t waste energy resenting it. Think of it as the rock-solid floor under everything else. Then go build your own money machine on top of it. That’s how you win with both.
