For many small businesses, cost is a priority when offering employee retirement benefits. ShareBuilder 401k is an online employee retirement benefits provider that offers low-cost retirement plans that are ideal for small businesses that want to provide a set of low-cost, diversified investment options. ShareBuilder 401k guarantees that employees’ investment fees stay below 1%, making it our pick for the best retirement provider for low fees.
8.7 / 10
ShareBuilder 401k is a great choice for low-fee plans because it keeps investment fees below 1%. This is in addition to its very low starting cost of $25 per month for solo 401(k) plans and $95 per month for companies with employees. Additionally, through ShareBuilder 401(k)’s automatic pricing discounts, your investment and administrative fees decrease as your employees’ invested assets increase. Sometimes, increases in plan participants can also lower your pricing.
It’s worth noting that ShareBuilder 401k is our top pick for low fees, whereas Human Interest is our top pick for affordability. Although both brands are competitively priced, Human Interest’s cost-saving efforts extend beyond low fees. Read our Human Interest review to learn why we think you get the most value for your dollar with this vendor.
Unlike some top employee retirement providers, ShareBuilder does not offer multiple service tiers. Instead, employers can choose from four types of 401(k) plans: solo, safe harbor, traditional and tiered profit-sharing. Each of these tiers is available for a flat monthly administration fee. They all come with a range of services and features, such as investment management, payroll integration and online resources.
Small businesses that use ShareBuilder 401k to manage their employee retirement benefits can choose from several standard 401(k) plans. Each plan type has its own rules and regulations, as determined by the IRS.
ShareBuilder offers retirement plans that let employers and employees choose from 22 index funds, one money market and five model portfolios. Although the company’s list of available investment options is not incredibly long, it is a solid selection of diversified options that allow participants to invest at a low cost and without undue risk. We appreciated how easy this list was to find, as many other vendors are more secretive about their investment options.
Employees can choose investments from the following types of funds:
In addition, ShareBuilder offers model portfolios to help employees understand how to allocate their funds according to their preferred strategy.
Tip: If you’re looking for a retirement benefits provider with more extensive investment options, consider our review of ADP employee retirement or our Paychex employee retirement review.
ShareBuilder 401k’s base pricing is stated clearly on the company’s website. Final pricing and savings are based on the total number of plan participants and plan assets. There may also be a one-time setup fee.
Automatic pricing discounts through ShareBuilder 401k are aimed at keeping management costs low as your business and plan assets grow. The total investment fee will always be under 1%.
For example, under a safe harbor plan with between 11 and 25 participants, the investment management fee is 0.75% if your team’s total plan assets add up to $499,999 or less, and the monthly administration fee is $145. As plan assets increase to between $500,000 and $1,999,999, the investment management and monthly administration fees decrease to 0.65% and $100, respectively.
We were impressed with how transparent ShareBuilder 401k is about its pricing. This transparency isn’t universal with our picks for the best employee retirement providers. Only one other provider that we reviewed, USA 401k, is arguably more transparent than ShareBuilder 401k. However, many employee retirement household names keep their prices hidden.
It can sometimes be a challenge to extend a good benefits program to employees that can boost company morale and reduce employee turnover, but that’s not the case with ShareBuilder 401k. To get started, call the sales team or click the Get Pricing button on the company’s homepage. Then, provide details about your business, including the company name, how many employees or owners you have, and whether or not you have an existing 401(k) plan. Next, indicate whether you already have a retirement plan and whether you need a safe harbor plan.
After that, ShareBuilder will recommend an appropriate plan for your needs and give you a quote. The process typically takes only five minutes, with another 10 to 20 minutes needed afterward to set up your account.
ShareBuilder users can log in to the administrator dashboard through the platform’s website. Notably, however, the company does not have a mobile app, whereas all our other top employee retirement picks do have mobile apps.
ShareBuilder 401k offers all users toll-free access to 401(k) advisors and customer care Monday through Friday from 9 a.m. to 8 p.m. ET. According to a company representative, many calls are answered in 20 seconds or less.
All ShareBuilder 401k customers are paired with a dedicated success manager for further assistance. This feature is new – previously, it was available solely with the company’s highest pricing tiers. It distinguishes ShareBuilder from Human Interest, which still offers dedicated management only to the highest-paying customers.
ShareBuilder 401k’s online help center provides employers and employees with extensive tools and resources, including a 401(k) savings calculator and, when employees register, a personally guided education experience. Employees who decline this personal guide to their accounts must instead watch a seven-minute video before getting started.
ShareBuilder 401k lacks IRA options as alternatives to 401(k)s. Conversely, ADP includes SIMPLE IRAs among its options; this type of retirement plan may work better for certain businesses and teams.
Unfortunately, ShareBuilder 401k doesn’t have a mobile application. This matters because mobile apps make it easy for employees and managers alike to manage benefits administration and investment planning anytime, anywhere. It’s also a drawback unique to ShareBuilder 401k. That said, in our conversations with ShareBuilder 401k company representatives, we were told an app could become available in roughly two years.
To figure out our top pick for low-fee employee retirement plans, we looked through prominent plan providers’ websites for fee information. We also spoke directly with company representatives to fill in any information gaps on their websites. Our goal was to establish which provider would deduct the least amount of money from employee and employer investments.
In our decision-making process, we prioritized the companies that were upfront with all their pricing details. The provider also had to be upfront about its plan types and investment options. This way, business owners know why they’re paying their fees, even when low. ShareBuilder 401k met all these criteria.
