Side Hustle Stacking: Why Two Gigs Is the New Normal

One side hustle is no longer enough. A survey of a thousand U.S. adults conducted in February found that 57 percent of people who earn money outside their main job now stack two or more gigs, as reported by The Penny Hoarder. The era of side hustle stacking has arrived: workers report a median of $1,275 a month from their gigs, or roughly fifteen thousand dollars a year. For a household near the U.S. median income of about sixty-two thousand dollars, that is nearly a quarter of annual earnings.

More than half of respondents, 53 percent, said they would struggle to cover essential expenses without their gig income. About three in four said rising costs have increased their reliance on side work over the past year. The top reasons are stark: nearly three in ten hustle mainly to cover living expenses, about one in five are building emergency savings, and roughly one in eight are paying down debt. This is not bonus money. It is budget money.

Why two gigs became the baseline

The survey's most revealing finding is that side work has become a form of insurance. Six in ten respondents said they treat their gigs as backup in case of job loss, and about four in ten would not quit their side hustle even if their employer gave them a raise of a fifth. Only 35 percent of working Americans keep a dedicated emergency fund, according to the outlet's separate savings research — so the second and third gigs are doing the job the savings account used to do.

Federal data backs up the scale. About 8.6 million Americans hold multiple jobs, according to the Bureau of Labor Statistics — and 4.6 million of them say they could not cover essentials without the extra work. The share of employees holding more than one job peaked at 5.7 percent in November 2025, the highest level recorded this millennium, as reported by IndexBox.

The time math behind side hustle stacking

Stacking pays, but it bills by the hour. The average person with a side gig works an extra 13 hours a week — 676 hours a year, the equivalent of 17 extra forty-hour work weeks. Over a lifetime, the outlet calculates, that adds up to more than a decade of additional full-time work. Respondents had been hustling for an average of 2.8 years, and a quarter of them had kept at it for more than five years.

The most popular gigs are familiar: rideshare and delivery at a quarter of respondents, creative services like writing and design at the same share, and e-commerce at 21 percent. Flexibility is the deciding factor — 73 percent of respondents said a flexible schedule matters most when choosing a gig, ahead of high earning potential or personal fulfillment, each cited by 39 percent. That flexibility is also the engine of side hustle stacking: short, shiftable gigs slot together in ways traditional part-time jobs never did.

The hidden invoice: burnout and taxes

The stacking strategy has a cost. Nearly two-thirds of respondents said they experience burnout at least sometimes, while just one in ten reported no burnout at all. Only 44 percent felt at least somewhat financially secure, even with the extra income flowing in — and nationally, more than six in ten working Americans live paycheck to paycheck. A related report from this publication, Side Hustle Burnout: Half of Gig Workers Can't Afford to Quit, explored the same tension from the other side.

Then there is the paperwork. Gig workers are usually treated as independent contractors, so no taxes are withheld and the worker must set money aside — yet one in five respondents said they had not set anything aside or were not sure what they owed. Only 43 percent set money aside and pay at filing time. Looking ahead, the future is split: 42 percent plan to keep hustling long term while 47 percent expect to quit eventually, which suggests side hustle stacking is as much a life stage as a lifestyle. For young workers treating gigs as career insurance, the takeaway is practical: pick gigs that flex around the main job, track the tax bill from day one, and set a number — the stack works best when it has an exit plan.
