Does the Retirement Math Still Work? What Goldman Sachs Found Out

New research from 5,000 Americans reveals why "just save more" is no longer enough – and what actually moves the needle on retirement readiness.

The jobs market gave markets a shot of confidence – but the Dow barely noticed.

The quick scan: Friday closed on a split note. Tech surged, the S&P hit fresh highs, but the Dow could barely be bothered to move. A stronger-than-expected jobs report lit the fuse under tech stocks, while the Iran situation – still unresolved, still simmering – stayed just quiet enough to let the bulls run.

S&P 500: +0.84%, 7,398.93 – A fresh record close, powered by a 3.27% surge in the tech sector
Dow Jones: +0.02%, 49,609.16 – Essentially flat; Boeing and Cisco led gains but couldn't offset losses in Salesforce and McDonald's
NASDAQ: +1.71%, 26,247.08 – The standout of the day, sailing past 26,000 as AI enthusiasm and tech earnings momentum kept the buying going.

What's driving it: April nonfarm payrolls came in at 115,000 – nearly double the 65,000 forecast – and the unemployment rate held at 4.3%. That's the kind of number that reassures investors the economy isn't cracking under the weight of $95 oil and a war that still hasn't officially ended. In the Strait of Hormuz, Trump confirmed the ceasefire was intact, though Tehran has yet to formally respond to the US peace proposal. Markets are treating a deal as a matter of when, not if – and pricing accordingly. Micron and Sandisk surged sharply on continued AI infrastructure excitement, dragging the NASDAQ higher. The week ended up 4.5% for the NASDAQ and 2.3% for the S&P 500 – six consecutive winning weeks, the longest streak since 2024.

Bottom line: For L-Plate Retirees with diversified portfolios, this is a healthy backdrop. Tech-heavy holdings have been the engine of recent gains, but the Dow's near-flatness is a reminder that not everything rises together. If you've been meaning to rebalance – this might be the moment to at least look at the numbers.

Goldman Sachs Asked 5,000 Americans About Retirement. The Answers Are a Wake-Up Call.

The scoop: Let me start with a number that stopped me cold.

Fifty-eight percent.

That's the share of working Americans who believe they will outlive their retirement savings. More than half. Not the bottom quartile of earners, not just people living paycheck to paycheck – across the board, across generations, across income levels. More than half of people saving for retirement genuinely expect to run out of money before they run out of years.

Goldman Sachs Asset Management surveyed 5,102 Americans in July 2025 – workers and retirees – and the report they produced is one of the more honest pieces of retirement research I've come across. It's called the "New Economics of Retirement," and the central question it asks is a deceptively simple one: does the retirement math still work?

The short answer: not the way it used to.

The Financial Vortex

Here's what's changed. Since 2000, the costs of the big-ticket items in American life – housing, healthcare, childcare, college – have risen dramatically faster than wages. Healthcare for a family costs more than three times what it did in 2000 as a share of income. Private college has roughly tripled. Renting has almost tripled. These aren't temporary inflation blips. They're structural shifts that have permanently narrowed the gap between what people earn and what they have left over to save.

Goldman has a name for this. They call it the Financial Vortex – the swirling pull of competing financial priorities that drags savings away before it can compound.

And the numbers are stark. Among working respondents, 67% say too many monthly expenses affect their ability to save for retirement. 64% say financial hardship – home repairs, unexpected costs – gets in the way. Nearly 60% say caring for and financially supporting family members is a drag on retirement savings. This isn't laziness or poor financial decisions. It's the structural reality of what it costs to live a normal life in 2025.

The Optimism Gap

Now here's where it gets interesting – and a little contradictory.

Despite all of this, nearly 70% of workers say they feel confident they'll meet their retirement goals. More than 80% of actual retirees say their retirement lifestyle is the same or better than before they retired, and that their income is on track. Retirees, on average, are living on about 60% of their pre-retirement income – and 71% of them are satisfied with that.

Goldman calls the gap between how confident people feel and how prepared they actually are the "Optimism Gap." It's not quite delusion. It's more like... selective awareness. People know things are hard, but they tend not to have fully reckoned with how hard the back half of the financial journey will be.

What actually moves the needle

So what actually works? The report identifies five interventions that measurably improve retirement outcomes.

Starting early – even small amounts – has a compounding effect that's genuinely difficult to overstate. The report models $500 a year invested from age 1 to 20 – that's a coffee-and-a-half per week – and shows it can add 14% more to retirement savings by age 65. Time is the asset most people don't realise they're wasting.

Access to an employer plan (401k equivalent) produces 29% higher savings-to-income ratios. The structure and automation of workplace plans removes the decision-making friction that causes people to delay or underfund their retirement.

A personalised retirement plan – not a generic online calculator, but an actual plan built around your circumstances – correlates with 27% higher savings ratios among retirees. People who plan, save more. This seems obvious until you realise that most people still don't have one.

Financial Grit – the report's term for the mindset combination of perseverance, long-term orientation, and resilience during hard periods – produces 49% higher savings-to-income ratios when comparing high-grit and low-grit respondents at the same income levels. Nearly half more in savings, just from how you approach the challenge mentally. That's not a small number.

And finally, blending guaranteed income with investment income in retirement – using something like an annuity for a portion of your savings alongside a standard drawdown strategy – can generate 23% more income from the same pool of assets. The 4% rule alone may not be the only tool in the kit.

None of these are silver bullets. The report is honest that for the 40% of workers living paycheck to paycheck, the structural headwinds are real and solutions are limited. But for the rest – people who are saving something, who have some discretionary capacity, who are within 10 to 20 years of retirement – the levers are clear.

The retirement math still works. It just requires more deliberate engineering than previous generations needed.

Actionable Takeaways for L-Plate Retirees:

  • Reframe the target. Most people aim for 50–57% of pre-retirement income in retirement. The survey data suggests retirees are largely satisfied on 60%. But financial advisors typically recommend 70–80% to maintain your standard of living. If your plan is built around a low replacement rate, stress-test it against your actual current spending – not an abstract percentage.

  • Get the plan on paper. Goldman's data is unambiguous: people with a personalised retirement plan have 27% higher savings ratios than those without one. If your plan currently lives in your head, or in a spreadsheet someone else made you three years ago, it's time to update it with your real numbers, real timeline, and real spending patterns.

  • Take the Financial Grit idea seriously. The 49% higher savings ratio among high-grit individuals isn't magic – it's the accumulated effect of not stopping contributions during downturns, not cashing out early, not letting a bad year become a bad decade. It's mostly about staying in the game. Which is easier to do when you've decided you're going to.

  • Don't dismiss annuities as old-fashioned. The blended approach – 30% in a guaranteed income product alongside 70% in a drawdown portfolio – generates 23% more retirement income from the same savings. It's not right for everyone, but it's worth modelling. A good financial adviser can run the numbers specific to your situation.

  • If you have adult children still building their lives, help them start early. The compounding math on early savings is ruthless in the best possible way. If you can help a younger family member start investing even a small amount now, the long-run impact will almost certainly exceed what you'd achieve putting the same money toward your own later-stage savings.

  • Acknowledge the Optimism Gap in yourself. This is the quiet one. Goldman found most people feel more confident than their actual savings trajectory warrants. That's not a character flaw – it's a human tendency. But it does mean that the time to audit your retirement assumptions is now, not when the gap becomes unavoidable.

Your Turn:
Does that 58% figure – more than half of savers expecting to outlive their money – surprise you, or does it match what you've sensed in conversations with people around you?
The report found that people with a personalised retirement plan saved significantly more. Do you have one? And when did you last actually look at it?
Of the five levers Goldman identified – starting early, employer plan access, personalised advice, financial grit, and blended income sources – which one do you feel you've done well, and which one gives you the most pause?
