Americans' retirement savings just hit record highs on the back of a roaring stock market — is your account falling behind?

But are you seeing the same results in your account? If not, here’s why and what you can do about it.

Retirement account balances on the rise

About one in three workers are feeling positive about their personal finances — and that’s, in part, due to a strong stock market that’s giving their retirement savings a nice boost. Overall retirement account averages for 401(k) balances stood at $155,800, up nearly 11% from Q1 and 403(b) balances stood at $145,000, up 12%, according to Fidelity. Individual retirement accounts also grew 10% over the period.

The findings come as more than half of workers surveyed (55%) say that they are extremely or very concerned about the economy — due to factors such as the rising cost of living, the geopolitical environment and job security, Fidelity said.

But what if your account isn’t keeping up? There are a few reasons why some savers might be seeing more impressive gains than others — and there’s more to it than economic conditions.

“Economic conditions and plan design may have an impact on workers’ retirement savings, but
savings behavior also plays a role in helping workers progress toward their retirement goals,” Fidelity said.

For example, Fidelity found that total average savings rates held at 14.4% for 401(k) savers in Q2 and 12% for 403(b) savers. It also noted that 81% of 401(k) participants were saving enough from their paychecks to receive their employer’s full matching contribution.

And, while IRA holders don’t get the benefit of employer matching, Fidelity’s data showed they increased their contributions by 36% compared to the previous year.

Bottomline, it comes as no surprise that your return rate depends somewhat on how much you can invest.

How to boost your savings

If your savings rate isn’t keeping up, there are a few things you can do. First, see if your plan design and investments are meeting your needs. If your employer offers matching contributions, try to meet the full match — otherwise you’re essentially leaving money on the table.

Of course, not all Americans have a 401(k) and matches aren’t always an option.

If you don’t have an employer-sponsored retirement plan, you may want to consult a financial advisor to build a portfolio (or revamp a current one) that will meet your financial goals. If you’re not seeing the returns you’d like to in your IRA or brokerage account, chances are you may need a more aggressive portfolio.
