80% of Gen Z Have Two Jobs. Retirement Pays for It

Goldman Sachs Asset Management’s 2026 Retirement Survey & Insights Report came out this week, and buried in the generational breakdowns is a number that should stop you mid-scroll: 80% of Gen Z and 77% of millennials are working a job beyond their main one. Not because they’re building an empire. Because the first job doesn’t cover the bills anymore.

Fortune’s coverage of the survey puts the sharpest point on it: 76% of Gen Z and 73% of millennials say they couldn’t make ends meet without that second paycheck. This isn’t a side hustle story. It’s a math story, and the math has a casualty — retirement savings, which is exactly what’s getting squeezed out while you’re working job number two.

The short version

What’s true	What it means for you
80% of Gen Z and 77% of millennials work additional jobs beyond their primary role — 61% of all employees do the same (Fortune, Goldman Sachs Asset Management)	The extra job isn’t the exception in your generation. It’s close to the default.
76% of Gen Z and 73% of millennials say they couldn’t make ends meet without that extra income	This isn’t hustle culture with a new coat of paint. It’s survival math, and you already knew that in your gut.
58% of workers say they’re on track for retirement, down from 68% a year ago	Confidence dropped 10 points in a single year. That’s not noise. That’s a direction.
66% of Gen Z, millennials, and Gen X expect to delay their retirement because of competing costs	Two out of three of your peers have already quietly moved their retirement date later. Have you?
Only 39% of workers increased their retirement savings in 2026, down from 55% in 2025	Fewer people are gaining ground — even the ones logging extra hours to try.
Housing is the single biggest obstacle to saving for Gen Z (38%) and millennials (36%), nearly double what it is for boomers (21%)	You’re not imagining that your generation’s math runs differently than your parents’.

What is the “Financial Vortex”?

Goldman Sachs coined the term Financial Vortex to describe how housing, healthcare, childcare, and education have eaten a growing share of income since 2000 — faster than wages have grown — leaving less room to save for retirement before a paycheck even clears. It isn’t a mindset problem or a discipline problem. It’s arithmetic, and the arithmetic has been getting worse for twenty-five years.

Goldman’s own numbers make the shape of it concrete. The cost of home ownership went from 33% of income in 2000 to 51% in 2025. Private college tuition climbed from 65% to 85% of income over the same stretch. Healthcare premiums for family coverage rose from 10% to 16%. None of those moved in a vacuum — they moved together, at the same time, against the same paycheck, which is the entire point of calling it a vortex instead of just “expenses.”

Why can’t Gen Z save for retirement?

Gen Z struggles to save for retirement because the basic costs of adult life have grown faster than income for 25 years straight, leaving less of every paycheck available for anything beyond rent, debt, and insurance. According to Goldman’s research, the biggest drivers are:

Housing costs that outpaced wages. Home ownership costs rose from 33% to 51% of income since 2000 — the single largest line item working against a 401(k) contribution.
Education costs that front-load debt into your twenties. Private college tuition climbed from 65% to 85% of income over the same period, which is a big part of why Gen Z’s debt load is growing faster than every other generation’s.
Healthcare that keeps climbing. Family coverage premiums rose from 10% to 16% of income — and that’s before this year’s marketplace premiums roughly doubled for people buying their own plan.
Too many monthly expenses, full stop. In Goldman’s survey, 67% of working adults say they simply have too many recurring costs to put anything toward retirement.
A shrinking gap between income and cost. As that gap closes, Goldman found, two-thirds of Gen Z, millennials, and Gen X now expect to delay retirement as a direct result.

That’s not a list of excuses. It’s a list of structural costs that moved while nobody was voting on it, and your paycheck is the thing absorbing the difference.

The second job isn’t hustle. It’s survival.

I’ve written before about why you need more than one way to make money — that post was about building income on purpose, as a hedge against a job market with no pensions and no loyalty. This survey is describing something different, and it matters that you can tell the two apart.

A hedge is a choice. What Goldman is describing for 8 in 10 of you is not. When 76% of Gen Z say they couldn’t make ends meet without the second job, that’s not a strategy — that’s the floor moving. Chris Ceder, Goldman’s senior retirement strategist, summed up the broader trend in five words: “Savings momentum seems to be stalling.” He’s talking about the whole workforce. For your generation specifically, momentum isn’t just stalling. It’s running in reverse while you’re working more hours than your parents did at your age, not fewer.

I know how that lands. You did everything that was supposed to work — the degree, or the trade, or the hustle to build a resume without one — and the second job still isn’t optional. That’s not a personal failure showing up on your bank statement. That’s twenty-five years of costs outrunning wages, landing on you specifically, at the exact moment you’re supposed to be starting to save.

What this is actually doing to your retirement

Here’s where the two-job reality and the retirement numbers meet, and it’s worse than either one looks alone. Working a second job buys you cash flow today. It does not automatically buy you a 401(k) contribution, because most second jobs — gig work, freelance shifts, a weekend side gig — don’t come with an employer match or an automatic payroll deduction. The hours go to rent and groceries. The retirement account doesn’t get touched.

That’s the mechanism behind Goldman’s starkest number: only 39% of workers increased their retirement savings in 2026, down sharply from 55% the year before. People are working more and saving less, at the same time, because the extra income is going somewhere, just not there. Fewer than 4 in 10 are gaining ground, even with more hours on the clock than they had twelve months ago.

And the confidence numbers are catching up to the reality. Only 58% of workers now say they’re on track for retirement, down from 68% a year earlier — a ten-point drop in twelve months, which is a fast move for a number that usually creeps. Two-thirds of Gen Z, millennials, and Gen X already expect to retire later than they’d planned because of it. That’s not pessimism. That’s people doing the math and writing down what they’re seeing.

What to actually do with this

You can’t out-hustle a structural cost increase, and nobody’s asking you to try. What you can do is make sure the second job isn’t quietly costing you the one thing it’s supposed to be protecting — your future.

If your main job has a 401(k) match, get the full match before anything else. It’s the one place in this entire economy where free money is still on the table. Skipping it while working a second job to cover costs is leaving money behind twice.
Treat any extra income from a side job as retirement money first, not last. Even $50 or $100 a month from a gig that has no match of its own compounds the same way a 401(k) dollar does — start now, even small, and let time do the heavy lifting.
Build the emergency fund before you build anything else. A chunk of why the second job feels mandatory is that one surprise expense — a car repair, a medical bill — has nowhere to land except a credit card. The emergency fund nobody told you to build is what turns “mandatory second job” into “optional second job” for the months when you actually need a break.
Check what your healthcare is actually costing you, especially if you’re buying your own coverage. Premiums moved sharply this year, and the second job might be partly funding a bill you haven’t fully looked at yet.
Don’t let the vortex talk you into giving up on saving entirely. I’ve written before about why financial nihilism is a trap — the costs are real, but “none of this matters so why bother” is the one response guaranteed to make the outcome worse.

None of this fixes the structural problem. Housing, tuition, and healthcare aren’t going to retreat back to 2000 levels because you read a blog post. But every dollar you route toward retirement now, even while working two jobs to survive, is a dollar that starts compounding decades before most of your peers’ dollars will.

The takeaway

Goldman put a number on something you already felt: the second job isn’t ambition, it’s the cost of 2026. What I want you to carry out of this isn’t despair about that fact — it’s a refusal to let the vortex also take the one thing that’s still fully in your control, which is what happens to the next dollar you touch. Make it count for the version of you that’s still thirty years from retirement, not just the version of you trying to make rent on Friday.
