401(k) vs Pension Plan

401(k) vs Pension Plan Overview

When it comes to retirement savings plans, there are a few different options to choose from. Two of the most common types of plans are 401(k)s and pension plans. Both of these options have their own set of pros and cons, so it is important to understand the differences between them before making a decision.

401(k)s are defined-contribution plans that are sponsored by employers. Employees can choose to contribute a portion of their salary to the plan, and the employer may also make matching contributions. The money in the 401(k) is then invested and grows over time. When employees retire, they can use the money in the 401(k) to support themselves. 

Pension plans are defined-benefit plans that are also sponsored by employers. Employees do not contribute to these types of plans. Instead, the employer makes contributions and invests the money. When employees retire, they receive a fixed income from the pension plan. 

What Is a 401(k) Plan?

A 401(k) is an employer-sponsored plan to which employees can contribute a certain amount from their salary, while employers may match their contributions. 

There are two main types of 401(k) plan: traditional and Roth. Contributions made to a traditional 401(k) plan are made of pre-tax dollars and withdrawals during retirement are taxable. On the other hand, Roth 401(k) are made of post-tax contributions and then get tax-free withdrawals during retirement. 

The employee has the option to contribute a portion of his annual salary to a 401(k) account provided it does not go beyond the contribution limits.

Moreover, 401(k) plans allow employees to choose among a wide variety of investment options such as stock mutual funds, bond mutual funds, target-date mutual funds, and index funds.

Advantages of a 401(k) Plan

401(k) plans have myriad benefits within the retirement savings realm. Some advantages of 401(k) plans include:

Tax-Deferred Contributions

Tax-deferred means that the investment earnings are accumulated tax-free until the taxpayer can take constructive receipt of the gains

Contributions to traditional 401(k) are taken directly from the employee’s paycheck before income taxes are withheld. This is a benefit to the employee because they will owe less in income taxes now.

The account’s dividends and capital gains also grow tax-deferred until the employee chooses to withdraw them in retirement.

Employee Has Control in Fund Management

Employees are usually responsible for choosing from the investment options offered in the 401(k) plan of their company. These typically include mutual funds and ETFs. Index funds are also a great option for those who do not enjoy the gamble of actively investing.

Should they wish to, employees have the choice to pay for account management especially if they have little knowledge about investments.

Employer Match

Employer matching means that an employer makes contributions to a 401(k) for a certain amount based on the employee’s contribution. 

The employer may match based on a specific percentage of the contribution up to a portion of the employee’s salary or an employer can also contribute a dollar-for-dollar amount.

A 401(k) matching program is basically free money for employees. 


In cases where the employee decides to change jobs, the money contributed to his 401(k), and its earnings belong to the employee.

There are different ways to keep the retirement plan invested and growing on a tax-deferred basis depending on the employee’s 401(k) plan type.

Suppose an employee leaves his employer but still has an old 401(k) with them. In that case, the employee may look for available options to remain in the plan or move it elsewhere like an IRA or another employer’s qualified retirement plan.

Disadvantages of a 401(k) Plan

401(k) plans are not without disadvantages. Some cons of 401(k)s include:

Investment and Management Risks

The 401(k) account is subject to the volatility of the stock market and other investment risks. The value of 401(k)s can go up or down, and it is possible to lose money in a 401(k).

Additionally, employees may end up paying fees for the investments and management of their 401(k) accounts. These fees can take a large bite out of investment returns over time and reduce the overall balance of the account.

No Guaranteed Payout Amounts

401(k)s do not offer guaranteed payout amounts in retirement as pensions do. The eventual size of the 401(k) account will depend on how much the employee contributes, how well the investments perform, and whether there are any fees charged.

What Is a Pension Plan?

A pension plan is a retirement plan that is known as a defined-benefit plan where employers, not employees, commit to paying a defined benefit to employees for life after they retire, typically according to how long they worked for the company.

Pension plans are expected to pay the retiree a set amount of income, regardless of the performance of the investment portfolio.

The employee often has the choice of taking either a lump sum on retirement or regular payments for life through an annuity. It can also be that those pension benefits may be inheritable by a surviving spouse or children, depending on the plan.

Advantages of a Pension Plan

Pensions offer some advantages that 401(k)s and other retirement savings plans do not. Some benefits of pensions include:

Guaranteed Benefits

There are laws that protect the employees’ pension plans in certain situations such as when their employers go bankrupt, when pension plans are underfunded, and when the pension falls into a loophole. 

In these situations, the Employee Retirement Income Security Act of 1974 (ERISA) has laws that protect the workers and retirees in traditional defined-benefit pension plans. 

ERISA created the Pension Benefit Guaranty Corporation (PBGC) that is funded by pension plan sponsors. 

The PBGC steps in if the employer terminates its pension plan because of bankruptcy. PBGC will pay employees up to the guaranteed maximum amount of any pension benefits employees have been promised that the employer cannot make good on. 

For cases like underfunded pension plans, PBGC pays an additional variable-rate insurance premium. The larger the underfunding of pension plans, the larger the variable-rate premium, which is also subject to yearly per-participant maximum. 

Death Benefit Can Be Passed On to Beneficiaries

One can receive pension plan benefits depending on the plan options and the beneficiary’s relationship with the pension owner. 

Generally, pension plans permit only one member- or their surviving spouse- to receive benefit payments. However, there are some instances that some may allow for a non-spouse beneficiary, such as a child. 

Per the IRS, the Employee Retirement Income Security Act of 1974 (ERISA) “protects surviving spouses of deceased participants who had earned a vested pension benefit before their death.”

Disadvantages of a Pension Plan

Pensions also have some disadvantages. These include:

Strict Withdrawals and Transfers

An employee’s pension is locked up with the employer until retirement day. That means if you have an emergency situation and need a large amount of money to take care of it, the pension will not help.

Generally, when an employee changes jobs, he will not be able to bring the funds from the pension plan. However, some employers offer vesting to their employees.

Vesting in a pension plan means ownership, which means that the employee will vest, or own, a specific percentage of their account in the plan each year. 

When the employee is 100% vested in his pension account, this means he owns 100% of it and the employer cannot take it back, or forfeit, for any reason. 

Employers may also offer a graduated vesting schedule. That is, employees will be 20% vested after three years, 40% vested after four years, 60% vested after five years, 80% vested after six years, and fully vested after seven years of service. In effect, the employee will be entitled to the vested portion of the plan based on the time they leave their employer.

Employees Have No Control in Fund Management

Pension plans are managed by the employer or an appointed professional fund manager. Unlike defined contribution plans, employees have no say in how the fund is being managed and where the money is being invested in a pension plan.

401(k) Plan vs Pension Plan Key Features

Similarities and Differences Between a 401(k) Plan and a Pension Plan

There are a number of similarities and differences between a 401(k) plan and a pension plan. Here are some of them:


– Both 401(k) plans and pension plans are retirement savings vehicles.

– Employers contribute to both 401(k) plans and pension plans.

– Both 401(k) plans and pension plans have tax advantages. In traditional 401(k) plans, contributions are taken directly from the employee’s paycheck prior to federal income taxes being withheld. 

On the other hand, distribution of pension benefits that are received at retirement or earlier are taxed under the state and federal income tax rates, but are not subject to the Social Security payroll tax. 

– Employees can contribute to both 401(k) plans and pension plans. It is important to take note that in pension plans, employers are responsible for the contributions, but employees may opt to contribute. The employee contributions in the pension plan are deducted from their wages. 


– A 401(k) plan is a defined-contribution plan while a pension plan is a defined-benefit plan.

– A 401(k) plan is funded by the employee and the employer, while a pension plan is usually only funded by the employer.

– A 401(k) plan allows employees to choose how their money is invested, while a pension plan does not.

– Pension payments are often based on a formula that factors in the employee’s years of service and salary, while this is not the case with 401(k) plans.

– When an employee leaves their job, they can take their 401(k) balance with them, but usually not their pension balance except if the employer allows vesting.

401(k) Plan vs Pension Plan Advantages and Disadvantages

401(k) Plan vs. Pension Plan: Which Is Best for You?

According to the Bureau of Labor Statistics, pensions remain common in the public sector. However, they have largely been replaced by defined contribution plans that are less costly to employers in the private sector.

The best retirement savings plan for you depends on your situation. If you want more control over how your money is invested and the ability to take it with you if you leave your job, a 401(k) plan might be the better option.

If you like the idea of a guaranteed income in retirement and do not mind not having access to the money until you retire, a pension plan could be the better option.

There are also other factors to consider when making your decision, such as whether your employer offers a match. 

If you have the option of both a 401(k) and pension plan, you might want to contribute to both. This can give you more financial stability in your retirement and provide a safety net in case one of the plans does not perform as well as you hoped.


There are different options available when it comes to retirement savings plans. Two of the most common are 401(k) plans and pension plans. Both of these plans have their own pros and cons, as well as similarities and differences.

The best retirement savings plan for you will depend on your individual situation and what is important to you.

If you have the option of both, contributing to both could give you the best chance at a comfortable retirement.

Contact a financial advisor to get help figuring out which retirement savings plan is best for you and how to make the most of the one you choose.

Yes, you can have both a pension plan and a 401(k) plan. However, you usually only have one active through your present employer, so it is most often the case to have a pension plan you have vested for through a previous employer. In this case, you can pay contributions to your 401(k), and your pension plan benefits when you retire have already been established.
Yes. If you decide to borrow from your 401(k), you need to sign a loan agreement that spells out the principal, loan terms, interest rate, any fees, and other applicable terms. You may have to wait for loan approval, though in some instances, you will qualify since you are borrowing your own money.
Yes, however, there are alternatives to borrowing against your pension. You can ask your credit or bank union if you are qualified for a short-term loan or ask your credit card company if you can make a cash advance.
After leaving the job, a person has several options for his 401(k). He may decide to leave the account where it is. Alternatively, he may roll over the funds from the old 401(k) into either an IRA or his new employer's plan.
Yes. You can elect to take your pension as a lump-sum payment, which is the total value of your account paid out all at once. If you choose this option, you will likely pay taxes on the lump sum in the year you receive it.

401(k) Plan | A Complete Beginner's Guide

401(k) Meaning

The 401(k) retirement savings account got its name from the Revenue Act of 1978, where an addition to the Internal Revenue Services (IRS) code was added in section 401(k). Consequently, 401(k) does not stand for anything except for the section of IRS tax code it was created in.

Traditional 401(k) vs Roth 401(k)

There are two types of 401(k) plans: Traditional and Roth 401(k)s. The traditional 401(k), named after the relevant section of the IRS code, has been around since 1978. With this plan, any contributions you make to the 401(k) account will reduce your income taxes for that year and will be taxed when they are withdrawn. Roth 401(k)s, named after former senator William Roth of Delaware, were introduced in 2006. Unlike a traditional 401(k), all contributions are made with after-tax dollars and the funds in the Roth 401(k) account accrue tax free. Typically, employees can take advantage of both plans at the same time, which is recommended among financial advisors to maximize retirement savings. Because of the way the contribution limits work, it is possible to invest different amounts into each account, even year-to-year, so long as the total contribution does not exceed the set limit.

Contributing to Your 401(k) Retirement Plan

Contributing to a 401(k) plan is traditionally done through one’s employer. Typically, the employer will automatically enroll you in a 401(k) that you may contribute to at your discretion. If you are self-employed, you may enroll in a 401(k) plan through an online broker, such as TD Ameritrade. If your employer offers both types of 401(k) accounts, then you will most likely be able to contribute to either or both at your discretion. To reiterate, with a traditional 401(k), making a contribution reduces your income taxes for that year, saving you money in the short term, but the funds will be taxed when they are withdrawn. With a Roth 401(k), your contributions can be made only after taxation, which costs more in the short term, but the funds will be tax free when you withdraw them. Because of this, deciding which plan will benefit you more involves figuring out in what tax bracket you will be when you retire. If you expect to be in a lower tax bracket upon retirement, then a traditional 401(k) may help you more in the long term. You will be able to take advantage of the immediate tax break while your taxes are higher, while minimizing the portion taken out of your withdrawal once you move to a lower tax bracket. On the other hand, a Roth 401(k) may be more advantageous if you expect the opposite to be true. In that case, you can opt to bite the bullet on heavy taxation today, but avoid a higher tax burden if your tax bracket moves up. Check out this article from Forbes to see the IRS tax rate tables for 2020, but remember that they are subject to change. A smart move may be to hedge your bets and divide your contributions between the two types of IRAs. If your employer allows you to add funds to both a traditional and Roth 401(k), then doing so reduces the potential risks of each. In this case, you will also have the ability to decide what proportion of your income goes into each account, meaning that as you near retirement and have a clearer idea of what position you will be in, you can put more into one or the other. When you do decide which avenue to take, make sure to thoroughly evaluate your decision. Moving funds from one account to another, such as from a traditional to a Roth 401(k), is time consuming and expensive, if even possible. Likewise, transferring a 401(k) from one employer to another in the event of a job change is also tricky. You want to make sure that when you put money into your plan, it will be able to sit undisturbed for a very long time.

Pension vs 401(k)

Pensions are similar to a 401(k), but are a liability to a company. If an employer offers an employee a pension, it means that they are promising to pay out a set amount of money to the employee at the time of their retirement. There is typically no option to grow this amount, but it also does not require any financial investment from the employee. Pensions, also referred to as defined-benefit plans, are becoming increasingly rare because it puts the financial burden of offering a retirement fund for employees entirely on the employer. 401(k)s, which are also called defined-contribution plans, take some of the financial pressure off of an employer, while also allowing employees to potentially earn a larger retirement package than they would have with a pension.

How Much Should I Contribute to My 401(k)?

Most financial experts say you should contribute around 10%-15% of your monthly gross income to a retirement savings account, including but not limited to a 401(k). There are limits on how much you can contribute to it that are outlined in detail below. There are two methods of contributing funds to your 401(k). The main way of adding new funds to your account is to contribute a portion of your own income directly. This is usually done through automatic payroll withholding (i.e. the amount that you wish to contribute, counting all adjustments for taxation, is simply withheld when receiving payment and automatically put into a 401(k)). The system mandates that the majority of direct financial contributions will come from your own pocket. It is essential that, when making contributions, you consider the trajectory of the specific investments you are making to increase the likelihood of a positive return. The second method comes from deposits that an employer matches. Usually employers will match a deposit based on a set formula, such as 50 cents per dollar contributed by the employee. However, employers are only able to contribute to a traditional 401(k), not a Roth 401(k) plan. This is especially important to keep in mind if you want to utilize both types of plans. A key variable to keep in mind is that there are set limits for how much you can add to a 401(k) in a single year. For employees under 50 years of age, this amount is $19,500, as of 2020. For employees over 50 years of age, the amount is $25,000. If you have a traditional 401(k), you can also elect to make non-deductible after-tax contributions. The absolute limit, counting this choice and all employer contributions, is $57,000 for employees under 50, and $63,000 for those over 50 as of 2019.
