Why We Chose ShareBuilder 401k as Best for a Do-It-Yourself Solution

Small business owners typically aren’t plan providers who understand the ins and outs of employee retirement plans. They shouldn’t need to be experts but should be led to expert solutions by a plan sponsor that requires as little effort as possible. Once you’re signed up, ShareBuilder 401k makes it easy for a business owner to establish a compliant plan without needing retirement plan expertise or even having to talk to a specialist. The vendor’s automated online process is simple enough for anyone to establish a new 401k plan entirely on their own. Of course, the company does have advisers if you do need to speak with someone during the implementation process, but many busy business owners are able to set up their chosen plan quickly and invite employees to participate without any outside assistance, which is why ShareBuilder is our choice for those looking for a do-it-yourself solution.

ShareBuilder recognizes that low investment fees can spur plan participation, so it keeps investment fees below 1%. That is well under the industry average of 1.65%, and ShareBuilder even touts its investment fees as being nearly 70% cheaper than its rivals’ fees. To encourage savings, ShareBuilder offers automatic pricing discounts: The more your company’s staff saves for retirement, the lower your monthly plan cost automatically becomes. We saw this pricing structure with some of the other plan sponsors we researched too.

ShareBuilder relies on index funds to keep its investment fees low. These are cheap, passive funds that track a basket of stock or index like the S&P 500. They are an excellent way to create a diversified portfolio of low-cost investments. Low investment fees won’t matter if the plan investment options are underwhelming, but ShareBuilder has a multitude of appealing options. Plan participants can select from several index fund types, including large-cap, mid-cap and small-cap stocks; bonds; treasuries; commodities; and alternative investments. The affordability doesn’t end there, though: ShareBuilder’s monthly administration charge is a flat fee, which helps ensure ongoing costs don’t spike on you.

Ease of Use

We found it incredibly easy to get started with ShareBuilder 401k. The company guides you through the entire process, first with one of its advisers and then with its automated online system. To kick things off, you can fill out an online form, have an adviser call you or contact the company to speak with an adviser immediately. The adviser provides you with a price quote specific to your business and goes over all of the plan details with you. You can then begin filling out the online plan paperwork and do the rest of the process entirely on your own.

We like that implementation can be completely do-it-yourself (DIY), but if you need help, an adviser can walk you through the setup. In our review of Paychex, our best pick for business owners seeking an all-in-one human resources and employee retirement solution, we found that it also offers that level of support.

When you’ve completed all of ShareBuilder’s online documentation, it then takes a few weeks to roll out the plan to your employees. Once the program is up and running, ShareBuilder offers digital tools to keep your team members engaged with their new benefit and proactive when it comes to their retirement finances.

Features and Services

ShareBuilder 401k offers several types of employee retirement plans, including solo 401(k), safe harbor 401(k), traditional 401(k) and tiered profit-sharing 401(k) plans. Beyond this plan variety, the DIY setup process and ShareBuilder’s commitment to keeping investment fees and employer costs down, the vendor has other valuable features and services that make it one of our best picks for a retirement plan provider.

Fiduciary Support

ShareBuilder 401k serves as your plan administrator, custodian, recordkeeper and ERISA 3(38) investment manager. We like how ShareBuilder takes management responsibilities off your plate, freeing up your time to focus on other business tasks. As the employer, you’ll still have to oversee payroll contributions and complete a year-end checklist, but ShareBuilder will help show you how.

Investment Options

Plan participants can choose from five managed portfolios or customize a portfolio from ShareBuilder’s selection of low-cost index funds. This flexibility is crucial to ensure your employees can make the investment choices they want.

Fund Research Tools

We like that you can view the roster of ETFs and managed portfolios on the ShareBuilder website. Each fund is linked to a Morningstar profile with information about the fund’s strategy, historical performance, asset allocation and other details.

Advisory Services

ShareBuilder has an investment committee that helps plan participants diversify their investments by managing the model portfolios and index funds. This means you and your team members needn’t be experts in investment choices. Top-notch professional help is easily accessible.


For both safe harbor and traditional 401(k) plans, you’re required to submit IRS Form 5500. The individual 401(k) plan carries this requirement as well, once your plan assets are $250,000 or greater. ShareBuilder prepares this form for you, so all you need to do is sign it and send it to the IRS.


All of ShareBuilder’s 401(k) plans allow participants to take out loans against their 401(k) of up to 50% of their account balance, though the amount can’t exceed $50,000. This is useful if someone finds themselves in a financial crisis or needing funds for a substantial purchase, such as a down payment on a new house.


We appreciate that ShareBuilder 401k charges employers a flat rate for plan administration. This keeps pricing simple, although the amounts listed below are just starting points. The company will give you a custom quote once it learns the specifics of your workforce. [If you want to know exact pricing from the start, see our review of USA 401k, which offers that kind of transparency.]

Plan TypeStarting Monthly Fee
Solo 401(k)$25
Safe harbor 401(k)$95
Traditional 401(k)$110
Tiered profit-sharing 401(k)$190
TipBottom line
Except for the solo 401(k), all of ShareBuilder's plans have payroll integration options. Using a highly rated payroll service can make managing employee retirement plans easier.

As noted above, investment fees for ShareBuilder plans are below 1%. Another upside of partnering with ShareBuilder is that the more your staff saves with your company’s chosen plan, the higher the discounts the vendor offers on your monthly rate and investment fee.

Implementation is where ShareBuilder 401k shines most compared to rivals. Its system uses a series of online prompts to guide you through the process of setting up your business’s retirement plan. Everything is laid out in an easy-to-understand format so busy business owners can grasp the information quickly and continue with the setup process without needing help from the vendor.

Once your plan is established, inviting employees to enroll takes only a few clicks. For them to be onboarded is just as straightforward, which fosters higher plan participation. This is a DIY solution unmatched by competitors, backed with the reassurance that you can get human assistance if you do need it.

Customer Support

Just because ShareBuilder 401k makes it easy to do things on your own doesn’t mean they don’t have amazing support. You can reach customer service by calling (800) 943-6108, Monday through Friday, from 9 a.m. to 8 p.m. Eastern time. You may also contact the company via email at

In the spirit of doing things on your own, you can take advantage of a bevy of self-help resources on ShareBuilder’s website. These include a 401(k) savings calculator, a cost comparison tool, informative guides and frequently asked questions (FAQs). The vendor also operates a blog that’s updated roughly twice a month with content about making the most of employee retirement plans.


One drawback of partnering with ShareBuilder 401k is the lack of a mobile app. A mobile app means your employees can enroll on the go and you can manage your plan wherever, whenever. We would prefer ShareBuilder to offer such an app, though we do appreciate that its website and portal are mobile responsive, so you can technically still get access via a mobile device as long as you have an internet connection. If you want a true mobile app, however, you may want to consider Human Interest as an alternate plan provider. Learn more about their employee retirement plan services in our full Human Interest review.

Another possible downside is that while ShareBuilder’s 401(k) plan options are robust, you won’t find some other plan types, such as individual retirement accounts (IRAs). If that account structure interests you more than a 401(k), we recommend checking out our review of ADP, which administers SIMPLE IRAs in addition to 401(k)s.

Did You Know?Did you know
Offering your staff a 401(k) is one thing while getting your employees to participate is another. Choosing a plan provider with low investment fees is one way to win workers over and boost your enrollment numbers. You may also want to explore automatic enrollment options.


When evaluating the best employee retirement plans for small businesses, we closely examined each plan provider’s features and services, ease of use, pricing structure, implementation process and customer service. To find the best do-it-yourself solution for business owners seeking a straightforward setup experience, we considered how easy each vendor makes it to sign up online without assistance. Then we took into account how simple it would be for a business owner to establish and roll out a retirement plan on their own. Finally, we weighed how effortless it is for employees to enroll without outside help. ShareBuilder 401k’s automated, self-service processes excelled on all counts.


ShareBuilder offers 401(k) employee retirement savings plans. Specifically, you can choose to set up a solo 401(k), safe harbor 401(k), traditional 401(k) or tiered profit-sharing 401(k) plan for your employees.
The services you get with ShareBuilder’s traditional 401(k) include the following:
  • Access to 401(k) advisers and customer care
  • Ongoing investment roster management, also known as ERISA 3(38) coverage
  • 22 index funds, one money-market fund and five model portfolios from which to choose
  • Roth 401(k) and tax-deferred options
  • Payroll integration options
  • Vesting schedule options
  • Automatic enrollment with qualified default investment options
  • Automatic pricing discounts

  • Small business owners who want a low-cost plan that keeps investment fees at a minimum.
