Key Points

Defined benefit plans guarantee a specific amount of retirement income, while defined contribution plans do not.
Employer contributions to retirement plans may vest over time, but worker contributions always belong 100% to the employee.
401(k) plans are popular, offering high contribution limits and the potential for employer matching.

Advantages of employer retirement plans

Here are some of the biggest benefits of participating in a workplace retirement plan.

Some plans offer guaranteed income. Defined benefit plans remove the risk of retirement investing for employees.
Employers often provide a company match on contributions for plans that don’t have a defined benefit. This is free money workers shouldn’t pass up, even if it means they must put money into their workplace retirement plan to earn matching funds.
Sign-up is generally simple. Some companies automatically enroll workers in retirement plans, while others require some simple paperwork. It can be easier to enroll in a workplace plan than it is to open your own retirement account and save independently.
Contribution limits are often higher. Workplace 401(k) accounts and other similar defined contribution accounts have higher limits than many tax-advantaged accounts that workers can open themselves, such as IRAs or health-savings accounts (HSAs).
Investing is often automatic. Workers can sign up to have contributions to their retirement account taken directly out of their paychecks, ensuring money is invested regularly. In some companies, contributions are automatically withdrawn unless workers opt out.

Disadvantages of employer retirement plans

Here are some downsides of employer retirement plans.

You may need to work a certain amount of time to become eligible. This could trap you in your job or may mean you need to consider other investing options if you don’t plan to remain with your employer long enough to qualify.
You have less flexibility in investments. If you have a 401(k) or similar defined contribution account, you may be limited to investing in a select few mutual funds offered in your workplace account. IRAs and brokerage accounts offer far more options. You can invest in whatever stocks, bonds, mutual funds, or exchange-traded funds (ETFs) you choose.
Some plans come with high fees. You may have to pay a management fee for your employer plan.
