401(k)s and HSAs Explained: The Retirement Tools Women Can’t Afford to Overlook

Let’s be real. Workplace benefits don’t usually get us excited. PTO? Yes, please. Health insurance? Absolutely. But tucked into your benefits package are two tools that can completely change your financial future: your 401(k) and your HSA. If you’ve brushed past them before, you’re not alone. The good news is, once you understand how they work, you’ll see why they deserve a prime spot in your retirement plan.

Your 401(k) and your HSA are two of the most powerful tools you’ll ever have to grow your money. They might seem overwhelming and confusing at first glance, but together they can set you up with the kind of financial security that means freedom down the road. If you’re single, if you’re childfree and if you know your retirement is 100 percent on your shoulders, these accounts matter even more.

What exactly is a 401(k)?

A 401(k) is an employer-sponsored retirement plan, which basically means it’s a special account set up through your job to help you save for the future. The big advantage is how the money goes in and how it grows. When you contribute to a traditional 401(k), the money is taken out of your paycheck before taxes are applied, which lowers your taxable income right now. That money then grows tax-deferred, meaning you don’t pay taxes on it until you take it out in retirement. Some employers also offer a Roth 401(k) option, where you contribute after-tax dollars but your withdrawals in retirement are tax-free.

The other huge perk? Employer matches. If your company matches a percentage of what you put in, that’s free money added to your account. No other investment will hand you an instant 50 or 100 percent return like that. And because your contributions are automatic with each paycheck, you don’t have to think about it every month. It just happens in the background, building your future while you live your life.

Don’t most women already have a 401(k)?

The encouraging news is that more women are participating in 401(k)s than ever before. The less-encouraging news? Our balances still trail men’s by a wide margin. According to Vanguard’s 2024 How America Saves report, women’s average 401(k) balances are about 70 percent of men’s. The gap comes from a mix of factors: the persistent wage gap, taking more career breaks, and in some cases contributing less because other financial priorities get in the way.

Here’s what the average 401(k) balance looks like by age (Vanguard):

• Under 25: $5,236
• 25–34: $42,700
• 35–44: $97,020
• 45–54: $179,200
• 55–64: $256,200
• 65+: $279,997

If these numbers feel out of reach, remember this: they’re averages, not benchmarks you have to chase. You don’t need to match them to retire well. What matters most is that you start where you are, and that you start now.

How much can you contribute to a 401(k) in 2026?

For 2026, the IRS contribution limit is $24,500, with an additional $8,000 catch-up if you’re 50 or older.

Even if you can’t contribute that much, do what you can, and make sure you’re at least getting your employer’s match. Think of the match as the easiest investment return you’ll ever earn. If your employer offers a 3 percent match and you don’t contribute at least 3 percent, you’re literally walking away from free money.

What does real 401(k) growth look like?

Let’s talk numbers, because sometimes the math is what makes it click.

Say you start saving $500 a month at age 30. If your investments grow at an average annual rate of 7 percent, by age 65 you’ll have close to $850,000. Now let’s say you wait until 40 to start. Same $500 a month, same growth rate. By 65, you’d have about $400,000.

The difference isn’t about how much you put in. It’s about how long that money has to grow. That’s the magic of compounding. It rewards time in the market more than timing the market.

Starting Age	Monthly Contribution	Balance at 65	Total Contributed	Growth
25	$200	$479,000	$96,000	$383,000
25	$500	$1.2 million	$240,000	$960,000
35	$500	$567,000	$180,000	$387,000
45	$500	$260,000	$120,000	$140,000

What is an HSA and why should you care?

If the 401(k) is your retirement lead, the HSA is the underrated co-star who gets second billing.

An HSA, or Health Savings Account, is tied to a high-deductible health plan. That phrase alone can feel like a red flag, but here’s why HSAs are worth considering: they’re one of the only accounts that give you a triple tax advantage.

1. Contributions go in pre-tax, lowering your taxable income today.
2. Your money grows tax-free while it’s in the account.
3. Withdrawals for qualified medical expenses are also tax-free.

That triple win makes HSAs unique. Some financial experts even call them “stealth IRAs” because if you don’t touch the money now and let it grow, you can use it in retirement in incredibly tax-efficient ways.

What are the 2026 HSA contribution limits?

For 2026, individuals can contribute up to $4,400, and if you’re 55 or older you can add a $1,000 catch-up contribution.

Should you spend your HSA now or let it grow?

That’s the million-dollar question. You can use your HSA for today’s doctor visits, prescriptions or dental bills. That’s perfectly valid. But if you can afford to cover those expenses out of pocket and leave your HSA money invested, the long-term payoff can be game-changing.

For example, if you invest $200 a month in your HSA assuming an average 7 percent annual growth, you will have a nice chunk of change waiting for you, tax-free, to cover the medical bills that are almost guaranteed to come with retirement.

Years of Saving	Total Contributions	Balance at 65	Growth
Start at 25	$96,000	$479,000	$383,000
Start at 35	$72,000	$227,000	$155,000
Start at 45	$48,000	$103,000	$55,000

Assumes $200/mo invested at 7 percent annual growth

Are women missing out on HSAs?

The data says yes. The Employee Benefit Research Institute found in 2023 that only 13 percent of women with HSAs were investing their balances, compared to 22 percent of men. That means a lot of us are letting our HSA dollars sit in cash instead of putting them to work. It’s like planting a garden but never watering it. You’ll never see the growth that’s possible.

So how do you make the most of these accounts?

Let’s cut through the jargon and get practical. Here are some simple ways to put these tools to work for you:

• Get the 401(k) match first. Don’t leave free money on the table.
• Don’t ignore the HSA if you’re eligible. Even small contributions add up.
• Increase contributions with every raise. It’s easier to bump up your percentage before you get used to the extra cash.
• Invest your HSA balance. If your provider offers investment options, don’t let that money sit in cash.
• Save your receipts. If you do cover medical costs out of pocket, save the receipts so you can reimburse yourself later.

Why this matters even more for single women

If you’re single, your retirement planning might look a little different. You don’t have the safety net of a partner’s retirement account or health benefits. You may not have anyone stepping in to help cover expenses later.

But that doesn’t mean you’re behind. It means you’re in control. Your 401(k) and HSA are about building wealth in your name, on your terms. They give you independence and flexibility. And they help ensure that the retirement you’re working toward, whatever you imagine that to be, is funded and secure.

The emotional side of saving

Let’s also be real. Saving for retirement doesn’t always feel exciting. Watching money leave your paycheck for accounts you can’t touch for decades can be frustrating. But here’s the shift in perspective: every dollar you put in is a dollar buying you future freedom.

That $100 contribution isn’t just money gone. It’s your future self sitting at a café in Paris, or growing your dream garden, or covering a health bill without panic. It’s security. It’s peace of mind. And it’s the kind of independence that women like us have worked so hard to claim.

Building a plan that works for you

Not everyone can max out their 401(k) or HSA. And that’s okay. The point isn’t perfection. It’s progress. Start where you are. Increase when you can. Keep going.

Maybe you can only do 2 percent right now. Great, start there. Bump it to 3 percent when you get your next raise. Treat it like a staircase. Every step counts.

And remember, these aren’t just accounts on paper. They’re tools to help you build the kind of life you want to live when the time comes to step away from work.

Retirement planning can feel overwhelming, especially if you’re doing it solo. But you don’t need to master every financial concept or max out every account tomorrow. What matters is that you start.

Your 401k and HSA are two of the most powerful wealth-building tools you have. As single women, we can’t rely on someone else’s savings or benefits. These accounts can help us take control of our financial independence today and create the security we’ll want tomorrow. So whether you’re fresh out of college or eyeing retirement in a decade, start where you are, grab the free money and don’t overlook the accounts that can do the heaviest lifting for your future self.
