Side Stacking is Growing as Side Hustling Shrinks

On March 3, 2026, LendingTree put a questionnaire in front of 2,049 American adults and asked a simple thing: do you have a side hustle? The answer came back at 33%. That’s down from 38% the year before and 44% in 2022. By every headline written over the last four years, side hustling was supposed to be swallowing the American workforce. Instead it was shrinking.

Then the same survey asked how much those people earned, and the number that explains side stacking turned up. The average side hustler was clearing $1,242 a month, up from $1,215 in 2025 and $473 in 2022. Fewer people, nearly triple the money.

Matt Schulz, LendingTree’s chief consumer finance analyst, chalked part of it up to a split economy. “In this K-shaped economy, while many Americans are struggling and desperately need as much income as they can find, many others are thriving and have less need to have that extra income on the side,” he said in the report. The casual hustlers cashed out. The serious ones stayed and got bigger. And the ones who stayed mostly aren’t running one gig anymore.

Side stacking is the practice of running two or more income-generating side hustles at the same time, usually alongside a full-time job, instead of relying on a single side gig. It’s the shape the side hustle economy took once the tourists left.

Quick answers

What is side stacking?

Side stacking is running two or more income-generating side hustles at the same time, usually alongside a full-time job, instead of depending on one side gig. The term spread through TikTok and Gen Z career content in late 2025 and describes a deliberate mix of income streams rather than a single hustle scaled up.

How many side hustles should you have?

Two or three is the practical ceiling for most people working a full-time job. Only one should be in active growth mode at a time; the rest run in maintenance. LendingTree found 32% of side hustlers spend 5 to 10 hours a week and 24% spend 11 to 15, which is roughly the capacity for two real streams.

Is side stacking worth it in 2026?

It depends on whether your stack is defensive or offensive. 61% of side hustlers say life would be unaffordable without the income, and 80% say it improves their quality of life. But 69% would trade the whole arrangement for one steady paycheck, which suggests most stacks are patching a shortfall rather than building something.

What is side stacking?

Side stacking is running two or more income-generating side hustles at once, usually on top of a full-time job, rather than relying on a single side gig. The distinction matters: a side hustler drives for a delivery app. A side stacker drives for a delivery app on weeknights, sells a design template library that earns while they sleep, and takes two consulting calls a month at $300 an hour.

The term went mainstream in October 2025 when Forbes senior contributor Bryan Robinson covered it as a spinoff of the broader side hustle trend. His piece traced the term to Resume.ai’s analysis of viral TikTok videos, where Gen Z workers were swapping strategies for running several income streams next to a nine-to-five.

Amanda Augustine, career expert at Resume.ai, framed it as risk management rather than ambition. “Instead of climbing a single corporate ladder, Gen Z professionals are choosing to build multiple income streams to protect themselves against an unpredictable economy,” she told Forbes. Her point: a generation that hit hiring freezes, mass layoffs, and record inflation before turning 30 learned not to put every egg in one paycheck.

Marium Lodhi, CMO at Software Finder, drew a sharper line between stacking and ordinary hustling. She described stacking as more organized and usually tied to software-driven work like contract gigs, consulting, or platform-based jobs. That’s the operative difference. A stack is a portfolio decision. A hustle is a reaction to a bill.

Why side stacking is growing while side hustling shrinks

Side stacking is growing precisely because the casual side hustle economy is contracting, and what’s left behind is a smaller group of people running more streams each. The LendingTree survey of 2,049 US consumers, fielded March 3 to 6, 2026, is the cleanest evidence for this.

Participation is down across every age group that drove the boom. Gen Z side hustling fell from 62% in 2022 to 57% in 2025 to 43% in 2026. Millennials went from 55% to 50% to 45%. Overall participation slid from 44% to 33%. This is the opposite of what almost every “side hustles are exploding in 2026” article claims.

Earnings moved the other way. Average monthly side hustle income went from $473 in 2022 to $1,215 in 2025 to $1,242 in 2026. That’s a 2.6x increase in per-hustler income while the population of hustlers dropped by a quarter.

Schulz offered a mechanical explanation for the participation drop. Starting a side business still costs money, and inflation squeezed the budgets that used to fund it. High interest rates and tight lending made people think twice about borrowing to start one. The barrier to entry got lower and the ability to clear it got worse at the same time.

The Bureau of Labor Statistics data on multiple jobholding tells a compatible story. Indeed Hiring Lab’s analysis of BLS figures put multiple jobholders at 8.69 million as of July 2026, about 5.4% of employed Americans. That rate is well below the 6.8% peak of summer 1995. Working several jobs isn’t historically unusual. What changed is that the streams are increasingly digital, self-directed, and chosen rather than assigned by a second employer.

So the honest read on side stacking is not that everyone is piling on hustles. It’s that a shrinking, more committed group is running better ones. If you’re deciding whether to build a stack in 2026, you’re joining a smaller and more professionalized field, not a crowded gold rush. Our breakdown of the biggest side hustle trends of 2026 covers where that professionalization is showing up first.

How many side hustles should you have?

Two or three, and only one of them should be in growth mode at any given time. Anything past three and you’re not stacking, you’re context-switching for free.

The time math sets the ceiling. LendingTree found 32% of side hustlers spend 5 to 10 hours a week on their side work and 24% spend 11 to 15. Call it 12 hours as a realistic weekly budget for someone with a full-time job. Split across two streams that’s six hours each, which is enough to make real progress on one and keep a second alive. Split across four it’s three hours each, which is barely enough to answer email.

Side Hustle School’s guidance lands in the same place from a different direction: two well-chosen hustles beat four mediocre ones, and you add the next one only when the first is self-sustaining. Barbara Corcoran has made the blunter version of the argument for years, that divided attention accomplishes nothing.

Here’s the operating rule that reconciles stacking with focus. At any moment, one stream gets 70% of your side-work hours. The others run in maintenance: fulfill orders, answer messages, keep the lights on, don’t chase growth. When the growth stream becomes self-sustaining, it drops to maintenance and a different stream gets promoted. That’s a stack. Four streams all in growth mode is just a slow-motion burnout schedule.

The cash, skill, and equity slots

The most useful way to pick what goes in a stack is to assign each stream a job. Most people stack by opportunity, taking whatever pays, and end up with three versions of the same thing: three ways to trade hours for dollars. A stack that builds toward something fills three different slots.

The cash slot pays this month. It’s fast to start, predictable, and requires no audience. LendingTree found gig and on-demand work is the most common side hustle category at 29%, which is exactly what this slot looks like in practice. The cash slot has no ceiling problem because it isn’t meant to grow. It’s meant to make the other two slots survivable.

The skill slot pays better every year you do it. Freelance and professional services sit at 26% of side hustles, and this is where they belong. The test for the skill slot is whether your rate a year from now will be higher than your rate today because of what you learned. Our look at online tutoring rates in 2026 shows the pattern clearly: general academic tutoring pays $19 to $40 an hour, while SAT prep, advanced math, and coding run $60 to $200. Same job category, different rung, and the only thing separating them is accumulated expertise.

The equity slot keeps earning after you stop working on it. A product, a content library, a small piece of software, a course. Creative, content, and media activities make up 23% of side hustles per LendingTree, though only some of that is genuinely asset-shaped. This slot pays nothing for months and is the first thing people cut when they’re tired. It’s also the only slot that ever ends the stack.

The mistake almost everyone makes is filling all three slots with cash work because cash work pays immediately and the other two don’t. That stack pays the bills and never ends. If you want ideas that fit the equity slot specifically, our list of micro SaaS ideas for solopreneurs and our guide to AI side hustles that actually pay are built around streams that keep earning.

Is side stacking worth it?

For most people running one today, side stacking is worth it financially and unwanted personally, which is a strange combination that the survey data captures well.

The financial case is strong. 61% of side hustlers say their life would be unaffordable without the extra income. 80% say it improves their quality of life, up from 77% a year earlier. 49% believe it supports their long-term financial security, up from 44%. Among six-figure earners that last number hits 65%, which suggests stacking works best for people who least need it.

Then the counterweight: 69% of side hustlers say they’d prefer a single main source of income if they had the choice, up from 65% last year. That number is going the wrong direction. More people are stacking out of necessity and fewer are enjoying it.

Schulz’s objection is worth taking seriously. “Relying on side hustles can be risky, in large part because of how unpredictable side hustle income can be,” he said. “It’s difficult to have a meaningful budget if you can never be quite sure how much money you’ll bring in during a given month.” A stack of three volatile streams isn’t three times as stable as one. It’s three separate sources of variance you now have to forecast.

There’s also a scale problem. For 28% of side hustlers, the income is 10% to 24% of what they earn. For another 28%, it’s under 10%. So for more than half of stackers, the entire arrangement moves less than a quarter of household income. That’s meaningful when you’re short on rent. It is not a path out of a job.

The version worth doing is the one where at least one slot is building something that outlives the effort. Everything else is a second job with extra steps and worse hours.

The burnout math nobody runs

Run the effective hourly rate before you add a stream, because the average side stacker is earning less per hour than the number in their head. Take the LendingTree averages: $1,242 a month at 12 hours a week works out to roughly $24 an hour before taxes, platform fees, mileage, or equipment. Split that across three streams with switching costs between them and the real figure drops further.

Tim Fung, founder and CEO of Airtasker, supports stacking but is direct about the guardrails. He points out that burnout is a risk in any work arrangement and that stacking requires discipline, boundaries, and honest tracking of your own capacity. His specific advice: keep count of what you’ve committed to and stop saying yes when you’ve run out of room for rest.

Fung adds a point most stacking advice skips. Quality has to hold across every stream, because ratings and reviews follow you and eventually determine what you can charge. A stack that degrades your work quality across the board lowers your ceiling in all three slots at once.

The practical test is simple. Before adding a stream, calculate what it pays per hour after every cost, then compare it to the rate you could charge in your skill slot if you spent those same hours getting better at it. Most third streams lose that comparison badly. The burnout risk is real, but the more common failure is quieter: people spend a year busy and end it with the same rate they started with. Our piece on the 5-to-9 economy covers how that time pressure plays out for people building after hours.

How to tell if your stack is defensive or offensive

A defensive stack replaces income you’re missing. An offensive stack builds something that eventually replaces the job. The two look identical on a calendar and completely different three years out.

Four questions separate them.

Does any stream earn without you? If every dollar requires an hour, the stack is defensive. Nothing compounds. You’ve built a portfolio of second jobs.

Is your rate in any stream higher than it was a year ago? If the answer is no across all streams, you’re maintaining, not building. The skill slot exists to make this answer yes.

Could you drop your lowest-paying stream tomorrow? If you can’t, the stack is load-bearing for basic expenses, which puts you in the 61% who say life would be unaffordable without it. That’s a real constraint, and the honest move is to name it rather than call it entrepreneurship.

Do the streams feed each other? A design freelancer selling design templates has two streams sharing one skill base and one audience. A design freelancer who also drives for a delivery app has two unrelated jobs. The first stack gets easier over time. The second doesn’t.

Most people reading this will answer no to at least three. That’s fine as a starting point and bad as a steady state. Pick one question and change the answer this quarter. The most common fix is the simplest: take the skill you already sell by the hour in your best stream, package a piece of it as something people can buy without you, and put that in the equity slot. Our guides to faceless AI UGC and what podcasters actually earn both show that pattern working, and our running list of 35 side hustle ideas is a reasonable place to find the first stream if you don’t have one yet.

Side stacking works when each stream has a different job. It fails when all of them have the same one.
