Got $5,000? Here’s How To Jumpstart Your Retirement Savings

Maybe you received a big tax refund, a bonus at work, or a small inheritance. It’s not a life-changing windfall, but it’s enough to make you pause and wonder: What’s the smartest thing I can do with this money?

If retirement feels far off, it might not be the first place your mind goes. But a $5,000 contribution towards your retirement savings today can grow to have quite the impact on your future, especially with time on your side.

Below, we’re walking through some of the most effective retirement accounts to consider. By exploring how to make the most of this lump-sum contribution, you can start building a well-rounded retirement income strategy for the future.

Why $5K Can Make a Big Difference

On its own, $5,000 won’t get you very far in retirement. But a principal contribution (like that $5,000) plus time can be a powerful combination—one that eventually yields thousands in additional retirement income. This is possible due to the power of compound interest.

When you contribute that $5,000 to an account, it earns interest or returns periodically. Let’s say you stick that $5,000 in a simple high-yield savings account, which earns 4% interest annually. After the first year, your initial $5,000 contribution will have earned $200—bringing your account balance up to $5,200. 

The following year, your account will earn 4% once again. But this time, it’s earning interest on a larger sum of money—your initial contribution plus the previous year’s earnings. Rather than yield an additional $200, now your 4% earnings come to $208 (that’s 4% of $5,200). Not a huge difference, for now. But amplify these compounding earnings across decades, combine them with additional contributions, and your retirement income has the potential to grow significantly. 

Using our example from above, let’s say instead of a high-yield savings account, you put your $5,000 into an IRA, which earns around 7% annually. Every month, you contribute an additional $300 to the account. In 30 years, you’ll have contributed a total of $113,000 to the account. But thanks to the power of compounding interest, the account will have a value of $378,120 (that’s around 2.3x the original contributions). 

Let’s say the timeline shortens to just 10 years, giving your money less time to compound. With the same parameters as our earlier example, the principal contributions would come to $41,000, with the total account value sitting at $59,574. Notably, this only gives us about 1.5x our original earnings, compared to the 2.3x earnings in the account over 30 years.

Best Retirement Accounts To Consider

Choosing the right type of retirement account influences how your money grows and, just as important, how much you’ll get to keep in retirement. The good news is, even a simple $5,000 contribution can grow significantly over time in a tax-advantaged account. Here are a few of the most common retirement accounts to consider.

Roth IRA

To fund a Roth IRA, you contribute after-tax dollars, meaning your contributions won’t be deducted from your taxable income. The trade-off, however, is that your investments grow tax-deferred between now and retirement—meaning you don’t have to pay taxes on earnings annually.

The real appeal of a Roth account, however, is the potential for tax-free withdrawals in retirement. To qualify for tax-free withdrawals, you’ll need to meet a few requirements. First, the account must have been opened for at least five years since the initial contribution. Then, you must either be:

• Age 59½ or older
• Disabled (as defined by the IRS)
• A beneficiary of an inherited account
• Purchasing your first home and using the withdrawal as a down payment (limited to $10,000)

Roth IRAs can be an especially tax-advantaged option for those who believe they’ll be in a higher tax bracket in retirement. Young professionals still earning modest salaries, for example, may benefit more from the delayed tax advantages of a Roth IRA than an executive hitting their peak earnings years, though everyone’s tax situation is different.

It’s also important to note that Roth IRAs have income limits. High earners may not be eligible to contribute to a Roth account directly. They may, however, be able to contribute to a tax-deferred retirement account (like a 401(k) or IRA) and complete a Roth conversion later. 

Traditional IRA

A traditional IRA is funded with pre-tax contributions. Your contributions, up to the annual limit, will be deducted from your taxable income for the year. Like a Roth account, the funds grow tax-deferred between now and retirement, but here’s where things differ. A Roth account can produce tax-free retirement income. But a traditional IRA, funded with contributions and earnings yet to be taxed, yields taxable retirement income. That means whatever you withdraw from your traditional IRA in retirement will add to your total taxable income.

You’ll be eligible to withdraw from your traditional IRA at age 59½. Once you reach age 73, however, your traditional IRA will be subject to required minimum distributions (RMDs). Each year, you’ll be required to withdraw a certain amount from the account, based on the account total and your life expectancy. These RMDs will also be subject to ordinary income tax.

While Roth IRAs have the potential to produce tax-free income in retirement, traditional IRAs do not. However, as we mentioned earlier, you may have the option to convert your traditional IRA pre-tax dollars into a Roth account—essentially “bookending” the tax benefits of both accounts.

401(k) or Employer-Sponsored Plan

Many employers offer a 401(k), 403(b), or other employer-sponsored retirement plan. Like an IRA, these accounts are funded with pre-tax contributions—meaning they lower your taxable income for the year.

Contributions to your 401(k) flow directly from your paycheck to the account. Each year, you determine how much you’d like to defer from your paycheck—this could also be determined as a percentage of your salary.

Regarding that $5,000 lump sum contribution, here’s the issue with 401(k)s: Most won’t allow you to make contributions outside of payroll. In other words, you can only contribute money from your paycheck into the account. Furthermore, you may not be able to make one-time adjustments to your payroll deductions either, depending on the plan rules.

You could, however, calculate your deductions and raise them (assuming you haven’t hit the annual limit) to factor in an additional $5,000 in 401(k) contributions for the year. Your employer may also give you the option to make an after-tax contribution to the account outside of payroll, though again, this will depend on the plan’s terms and conditions. After-tax contributions will not lower your taxable income for the year they’re made, but they’ll still help grow tax-deferred earnings within your retirement account.

Health Savings Account

An HSA (Health Savings Account) can be a surprisingly powerful retirement tool, especially considering its intended purpose is to cover qualified medical expenses. If you’re enrolled in a qualifying high-deductible health plan (HDHP), you will be eligible to open and contribute to an HSA. Like the other accounts, there is an annual contribution limit. However, when used to fund eligible medical expenses, HSAs offer a rare triple-tax advantage.

First, contributions to the account are tax-deductible. Any earnings within the account grow tax-deferred, and withdrawals used for qualifying expenses are tax-free as well.

While the HSA is designed to help cover current and future health care costs, it can double as a stealthy retirement savings account. After age 65, you’ll be allowed to withdraw funds for any reason without penalty—though non-medical withdrawals will be taxed as ordinary income. If you don’t need the money to cover health care costs now, you can invest your HSA balance and let it grow tax-free for years.

Unlike 401(k)s, you can make one-time, nonpayroll contributions to your HSA—meaning you could use your $5,000 to contribute to an HSA, if you have one. The only caveat here is that the 2025 contribution limit is capped at $4,300 for self-only plans, or $8,550 for family plans.

Smart Moves To Keep Your Momentum Going

Building a strong retirement foundation doesn’t happen all at once. Rather, it’s the product of consistent action over time. Even if your financial circumstances don’t allow for another large contribution anytime soon, setting up small, recurring contributions can be just as impactful (if not more) towards building your retirement savings.

An automatic transfer of $50 to $100 each month might not feel like much in the moment, but it adds up—especially when you factor in compound growth over decades.

Increase Contributions Over Time

Your contributions can (and should) grow alongside your salary. One of the easiest ways to increase your retirement savings without feeling a pinch is to bump up contributions each time you receive a raise, bonus, or unexpected windfall.

As natural inflection points in your financial life, these are ideal opportunities to adjust your savings rate without affecting your current lifestyle. Many 401(k) plans even offer an automatic escalation feature that will increase your contribution percentage each year unless you opt out.

Review Your Progress

It’s also a good idea to review your retirement progress at least once a year. You don’t have to undergo a deep-dive analysis (unless you feel it’s required). A quick annual check-in can help you confirm that your account contributions align with your goals, your investments reflect your risk tolerance, and your tax bill is monitored. If you’re working with a financial advisor, this is often part of your annual planning process. If not, you can still set a calendar reminder each year to assess and adjust as needed.

Stay Invested During Market Volatility

It’s normal to feel uneasy during market volatility, but succumbing to your emotional impulses (like selling during a downturn) can lead to long-term losses.

Unless you’re right at the threshold of retirement, your investment horizon is likely measured in decades, not months. Stay the course and give your portfolio time to recover. Keeping your money invested long-term will help capture the benefits of compound growth.

The Bottom Line

Even a modest sum like $5,000 can lay the groundwork for a more secure future. The key is to get started, choose the right account, and stay consistent, because time, not timing, is what grows wealth.
