There are 62.6 million workers without access to an employer match, according to data from the Economic Innovation Group. However, even workers who have access to employer matches may not be taking full advantage of this benefit.

Here's more information about how 401(k) retirement plan matching works and examples of common employer match formulas. This is free money that employees may be leaving on the table.

The ultra-rich have also been investing in art from big names like Picasso and Bansky for centuries. And it's for a good reason: Contemporary art prices have outpaced the S&P 500 by 136% over the last 27 years.

A new company called Masterworks allows everyday investors to buy a small slice of $1-$30 million paintings from iconic artists, all without needing any art expertise.

How 401(k) employer matching works

A 401(k) match is when a company that you work for offers a 401(k) plan and, as an extra benefit, offers to match a portion of your contributions to your 401(k) account. When an employer offers a match, it's essentially like giving you free money that's added to your overall 401(k) retirement savings. Many companies offer this; however, not all companies offer the same match formula.

Examples of common 401(k) employer match formulas

According to Fidelity, there are several types of employer match formulas. A full match is when your employer matches your contributions 100%; a 50% match is when they match $0.50 for every dollar you contribute.

Most employers match up to a certain percentage. So, an employer might offer a 100% match on the first 3% you contribute and 50% on the next 2%. So, if you contribute 5% of a $70,000 salary, you would get a 100% match on the first 3% from your employer at $2,100. Then, you'd get a 50% match on the next 2%, which is $700. In total, you would contribute $3,500, and your employer would contribute $2,800.

The importance of understanding your employer's vesting policy

The most important part of a 401(k) match is the vesting schedule. Every company has its own vesting policy. When you are fully vested in your 401(k) retirement plan, that means that you have full ownership over the contributions that your employer has made on your behalf. If you switch jobs or get laid off before being fully vested, you will have to forfeit your employer's match.

According to 2024 data from the Plan Sponsor Council of America, only 44.1% of employers that offer a match give immediate full vesting. So, it's important for employees to get information about their 401(k) match and vesting schedule before deciding whether to switch jobs.

Where to get information about your 401(k) match and vesting schedule

Check their benefits portal or ask HR to confirm they're contributing at least enough to capture the full match, and think carefully about timing if a job change is on the horizon

To find out about your 401(k) match and vesting schedule, the first place to check is your benefits portal. Your company benefits should be outlined here or within the summary plan description (SPD) of your 401(k). If you're still not sure about your company's benefits, you can ask your human resources department.

What to know about your 401(k) match when switching jobs

The most important thing to know about your 401(k) when deciding to switch jobs is whether or not you are fully vested in your 401(k) plan. If you're not, you may lose out on the free employer match money when you change jobs.

Additionally, many people lose track of their 401(k)s when leaving a job or decide to cash out. Cashing out a 401(k) before age 59 and a half means that you may be subject to penalties and potentially higher taxes.

Tips on how to maximize your 401(k) match

There are a few things that employees can do to maximize their 401(k) match. The first thing is to contribute enough to get your full employer match. Then, anytime you get a raise or a bonus, increase your 401(k) contribution. Having good personal finance habits and a solid emergency fund outside your 401(k) can also help you avoid early withdrawals or taking out 401(k) loans.

Common mistakes to avoid with your 401(k) match

One of the most common mistakes to avoid with your 401(k) match is not contributing enough to receive the full match. It's common for this to happen, especially if your employer's matching formula is complex and difficult to understand. Sometimes, employers change their benefits policy as well. To stay up to date on your employer's 401(k) matching benefits, speak to your human resources department.

Bottom line

Making sure you get your full 401(k) employer match is one of the most straightforward ways to boost your retirement savings and help you achieve a stress-free retirement one day. To do that, though, take the time to fully understand how your match works and what your employer's vesting policy is. Also, cultivate good personal finance habits so that you can continue increasing contributions throughout your career.
