The Rise of Multiple Income Streams and Side Hustles in America: What Single Women Need to Know for a Secure Retirement

If it feels like everyone you know has a side hustle right now, you’re not imagining it.

From freelance consulting and Etsy shops to tutoring, ride-share driving and online businesses, multiple income streams have shifted from a “nice-to-have” to a financial strategy many Americans rely on. What started for some as a pandemic-era safety net has now become a permanent feature of modern life.

And for women, especially single women planning, saving and investing for retirement, this trend isn’t just interesting. It’s deeply relevant.

How Prevalent Are Side Hustles in America?

The short answer? Very.

Reports show that about 72% of U.S. workers rely on at least one source of secondary income as of early 2026. That’s nearly three out of four workers earning money beyond their primary job.

Other surveys define side hustles more narrowly, focusing specifically on gig work or structured part-time work, and still show striking participation rates. Data cited by Hostinger and Bankrate indicate that about 36% to 37% of Americans hold a defined side job or gig role.

In other words, whether you measure broadly or narrowly, the side hustle economy is substantial. And growing.

The Market Is Booming

The global side hustle economy was valued at $556.7 billion in 2024 and is projected to reach $2.15 trillion by 2033, reflecting a compound annual growth rate (CAGR) of approximately 16.18%, according to Hostinger’s 2026 data.

This isn’t a temporary spike. It’s structural change.

Even more telling: 71% of workers believe side income will become even more common in the coming year, and 26% suspect it could eventually replace traditional annual raises as the primary way people increase earnings.

That belief alone changes how people plan their careers and their retirements.

Why Are People Seeking Multiple Income Streams?

The motivation has shifted in recent years.

For many Americans, side hustles used to be about passion projects or extra “fun money.” Today, the data tells a more practical story.

1. Rising Costs and Inflation

The majority of side hustlers say rising costs have made secondary work a necessity, and 38% cite inflation specifically as the primary driver.

Everyday costs like groceries, housing, healthcare and insurance have forced many people to rethink the stability of relying on a single paycheck.

2. Building a Financial Safety Net

Hostinger reports that 27% of people use side hustle income to build emergency savings and 16% use it to pay off debt.

For single women, this is especially powerful. Without a second household income to buffer unexpected expenses, having an additional revenue stream can be the difference between tapping retirement savings early and staying on track.

3. Career Insurance

Layoffs and industry disruptions have changed how people view job security. According to recent surveys, 52% of workers say they feel “definitely more secure” because they are no longer reliant on a single employer.

This concept of “income diversification” mirrors investment diversification. Just as you wouldn’t put your entire retirement portfolio into one stock, many women are realizing it may not be wise to rely on one employer alone.

Who Is Most Likely to Have a Side Hustle?

Generational Differences

According to a 2025 Bankrate/SurveyMonkey report:

• Gen Z (18–27): 48% have a side gig
• Millennials (28–43): 44% have a side gig
• Gen X (44–59): 33% have a side gig
• Baby Boomers (60–78): 23% have a side gig

Younger generations lead in participation, but it’s notable that nearly one in four Baby Boomers is also engaged in side work.

This tells us something important. Side hustling isn’t just a young person’s game. It’s increasingly part of the retirement transition strategy.

Earnings by Generation

The same Bankrate/SurveyMonkey 2025 report found:

• Millennials earn an average of $1,129 per month from side hustles
• Gen Z averages $958
• Gen X earns $751
• Boomers average $561

Even at the lower end, $500 to $1,000 per month can significantly accelerate debt payoff, emergency savings, or retirement contributions.

For example, an extra $750 per month invested at a modest 6% return over 20 years could grow to over $340,000. That’s not trivial.

Gender Differences

Men and women participate at similar rates, approximately 55% male and 45% female participation, according to Hostinger and Bankrate data.

But gender disparities persist. Men earn approximately $1,034 to $1,195 per month, while women earn approximately $611 to $735 per month. That’s a meaningful income gap, even in side hustles.

For single women already facing the long-term impact of the gender pay gap and longer life expectancy, this difference compounds over time. It underscores the importance of pricing services appropriately, negotiating rates and choosing scalable side income opportunities where possible.

The Pros of Multiple Income Streams

1. Greater Financial Stability

A second income stream can help avoid credit card debt, prevent early retirement withdrawals, smooth cash flow volatility and fund retirement accounts more aggressively.

2. Skill Development

Many side hustles build digital literacy, marketing skills, negotiation ability and entrepreneurial thinking. These skills can enhance primary career earnings or provide a bridge into retirement consulting or part-time work.

3. Autonomy and Confidence

Hostinger reports that 49% of young hustlers value being “their own boss.” For women who have experienced workplace instability, discrimination nor glass ceilings, building something independently can be empowering.

The Cons of Juggling Multiple Gigs

1. Burnout

Many side hustlers report experiencing burnout due to overwork. This is especially concerning for women who often shoulder disproportionate caregiving and household responsibilities.

2. Health Declines

Hostinger reports that 21% of workers experience a decline in physical health due to the extra workload. Sleep deprivation, stress and lack of downtime are not long-term wealth strategies.

3. Opportunity Costs

About 20% report significantly less time for family or personal hobbies. Time is a nonrenewable resource. Retirement planning isn’t just about money. It’s about designing a life you don’t need to escape from.

Is This Changing How We Think About Retirement?

Absolutely. The classic vision of retirement that includes working hard for 40 years, stopping working entirely at 65 and living off savings is evolving.

The “Hustle” Retirement Fund

With nearly half of side hustlers contributing a meaningful portion of retirement savings from extra income, multiple income streams are becoming part of formal retirement strategy.

Redefining “Retired”

Research from D.A. Davidson & Co. found that 60% of current retirees wish they were engaged in part-time work.

Many retirees now consult part-time, tach online, sell handmade goods and monetize hobbies.

They don’t necessarily do this because they have to, but because it reduces portfolio withdrawals, keeps them socially engaged and preserves purpose.

Delayed Retirement and Micro-Side Hustles

Economic uncertainty has also pushed some older Americans to delay full retirement and instead transition into “micro-side hustles,” low-maintenance income streams that supplement Social Security and investments.

For single women, who statistically live longer and often have smaller retirement savings due to career breaks and wage gaps, this hybrid retirement model may offer flexibility and security.

What Single Women Need to Know

If you’re planning retirement on your own, here are some grounded, practical considerations.

1. Don’t Let Hustle Replace Strategy

A side hustle is not a substitute for a diversified investment portfolio, adequate retirement account contributions, emergency savings and insurance planning. Think of side income as fuel, not the engine.

2. Protect Your Health

No amount of extra income is worth chronic exhaustion. Sustainable wealth requires sustainable energy.

If burnout is creeping in consider raising rates instead of increasing hours, automate or outsource parts of the hustle or shift toward scalable income streams.

3. Be Tax-Smart

Side income often comes without withholding. Make sure you set aside money for quarterly taxes, track expenses and contribute to tax-advantaged accounts like a SEP IRA or Solo 401(k) if eligible. This is where side income can truly accelerate retirement readiness.

4. Close the Side Hustle Gender Gap

Women earn significantly less in side hustles on average. That means you need to price confidently, benchmark your rates, negotiate contracts and invest in skill-building that raises your earning ceiling. Your time has value, so make sure you are paid for it.

5. Consider Longevity

Women live longer than men on average. That means your retirement portfolio needs to last longer.

A well-structured side income stream in your 50s and 60s reduces pressure to withdraw from investments, allows compounding to continue and preserves long-term financial independence.

The Bigger Picture: A Cultural Shift

The rise of multiple income streams reflects something deeper, which is distrust of traditional employment stability. It’s a recognition that wages alone may not keep pace with costs, that there is desire for autonomy and that the idea of retirement is being redefined.

It also reflects resilience. Americans, and especially women, are adapting. But remember, your worth is not measured by how many income streams you juggle. Financial security is the goal. Exhaustion is not.

Designing Your Version of Security

For single women planning for retirement, the rise of side hustles presents both opportunity and caution.

Yes, multiple income streams can accelerate savings, increase resilience and expand options. But they should also serve your long-term vision, not consume it.

Retirement is no longer a cliff you fall off at 65. It’s becoming a gradual shift, a rebalancing and a portfolio of income streams, some active, some passive.

The question isn’t “Should I have a side hustle?” The better questions are:

• Does this income stream support my retirement goals?
• Is it sustainable?
• Does it align with the life I want 10, 20, 30 years from now?

You deserve financial independence. You deserve options. Multiple income streams can be a powerful tool. Just make sure you’re the one in control of them, not the other way around.
