Human Interest: Easiest to Use Low-cost 401(k) Provider

Human Interest was founded on a belief that many 401(k) companies charge excessive or hidden fees. As a disrupter to the industry, it is an investment platform that can administer your 401(k) plan and is great for small business owners willing to use an online provider for ease of use to save time and money.

Compared to other 401(k) companies, Human Interest aims to keep administrative costs down and utilizes flat administrative fees, so business owners know what to expect. While it doesn’t offer payroll services in-house, it works well with most systems and provides a core group of services very efficiently.

Investment Options

Unlike some other providers, Human Interest provides limited investment options. Still, the funds it offers are typically the most popular types of investment vehicles for retirement accounts and provide ample opportunities for participants to grow their assets.

Human Interest investment options include:

• Mutual funds: Human Interest provides 401(k) participants with an array of well-diversified mutual funds to choose from, offered by reputable companies.
• Target date funds: 401(k) participants can also invest in funds that are structured specifically for shifting debt-to-equity ratios as investors move closer to retirement. While potentially beneficial, target date funds can involve additional fees.

Setup & Plan Administration

Human Interest has a core group of services that it provides very efficiently. For other items like payroll services, it works very well with any outside providers that a small business relies on. The primary 401(k) services offered by Human Interest include:

• Plan design and administration
• Recordkeeping
• Trade processing
• Guidance on investment options
• Financial literacy courses and employee resources

Despite having limited brick-and-mortar options, each 401(k) client gets a dedicated account manager, and the company works with other types of providers to make administration seamless for business owners and employees. Human Interest even provides support for 401(k) plan participants who want to borrow against their retirement assets.

Vanguard: Best 401(k) Provider for Mutual Funds

Vanguard is the largest mutual fund company in the world, managing more than $4.5 trillion in assets. The company offers professionally managed mutual funds and ETFs that can potentially be used within a 401(k) plan, depending on the design of the plan. Vanguard is the ideal provider of mutual fund options for any 401(k).

In the 401(k) space, Vanguard’s role is confined to a pure money manager. It doesn’t do plan administration, payroll, or banking but is very highly regarded as a money manager and a great source of investment options for your 401(k) plan. Vanguard’s funds have many different focuses—domestic vs international, stocks vs bonds, aggressive vs conservative—and it offers investors a good deal of diversification at an exceedingly low cost.

Investment Options

Vanguard’s primary role in the 401(k) industry is providing well-managed investment options, including:

• Mutual funds: Vanguard offers more than 100 mutual funds that are well-managed and among the most inexpensive in the industry. They are available to 401(k) participants through most plan administrators.
• ETFs: For those employers who structure a 401(k) to include a brokerage option, Vanguard also offers a line of ETFs that are also well-diversified and low cost.
• Target date funds: Vanguard offers a wide array of funds that are designed to adjust the underlying portfolio automatically over time as a targeted retirement date draws closer. Unlike other providers that tend to layer fees for target date funds, Vanguard’s target funds are among the most cost-effective in the mutual fund industry.

Setup & Plan Administration

On its own, Vanguard is not a plan administrator. Vanguard offers relatively easy integration with banks and payroll service providers when used through an administrator platform. However, like most mutual fund companies, it still has substantial room for improvement when it comes to technology and seamless integration.

Vanguard 401(k) Costs

Vanguard’s expenses in the 401(k) space are confined solely to fund charges expressed as a percentage of the total assets invested. These fees increase as the amount invested rises and are deducted from participant accounts automatically.

Customer Service

Other 401(k) plans typically hold Vanguard funds through an intermediary like a plan administrator. This means that Vanguard doesn’t coordinate customer service directly. Instead, customer service typically is handled by a 401(k) administrator.

Paychex’s role in the process is confined but effective and cost-efficient. For example, it will facilitate pretax or post-tax employee contributions as well as any employer match.

Paychex 401(k) Costs

Because Paychex does not provide plan administration or investment options, its costs are confined to payroll services, should you decide to use them. Its billing structure is based on the number of employees and pay periods per year and increases with the number of employees and number of annual periods. There are additional charges for processing employee W-2s and other tax forms, and you need to contact them directly for a free quote.

Customer Service

While Paychex is focused almost exclusively on payroll and human resources (HR) solutions, there are more than 100 offices throughout the country that small business owners can contact for assistance.

How We Evaluated the Best 401(k) Providers

Our guide reviews providers on specific criteria that we know are important to investors and business owners when establishing a new solo 401(k). We considered traditional banks, HR companies, mutual fund companies, payroll providers, and third-party administrators in the mix. We didn’t limit rankings based on cost since those with higher costs often have higher-level customer service and retirement planning opportunities.

After looking at various types of 401(k) providers, here are the criteria we used to determine the best:

• Role in the process
• Ease of integration
• Reputation
• Investment options
• Administrative costs
• Employer and employee customer service

Ultimately, there are many 401(k) options out there. Business owners should choose a provider that allows them to conduct the types of investments they desire for a reasonable price.

Alternative Options to a 401(k)

The 401(k) is not the best option for every business owner. Depending on how much you will invest and how much time you want to spend on administering the plan, you may opt for other retirement savings vehicles such as a simplified employee pension (SEP) or savings incentive match plan for employees (SIMPLE) IRA. These options can be more cost-effective for someone not looking for many bells and whistles.

SEP IRAs

The SEP IRA can be an ideal alternative if you’re self-employed or own a small business with less than three to five employees. If you make more than $75,000 per year, a SEP IRA can be especially advantageous because you can contribute up to 25% of income or $57,000 without the added expenses that a 401(k) has.

The key difference with SEP IRAs is that employers are required to fund all contributions for themselves as well as their employees. There are no employee salary deferrals or matching contributions. For businesses with more than three to five employees, this can often be more expensive than a 401(k) but, for a sole proprietor, this can be a great option.

SIMPLE IRAs

A SIMPLE IRA is literally simpler than a 401(k). It has even been called the “poor man’s 401(k)” because it offers many of the same benefits for small businesses with a few employees, without the expense of administering a 401(k).

Like a 401(k), SIMPLE IRA contributions are composed of employee deferrals and matching contributions. However, the contribution limits are lower for a SIMPLE IRA capping out at $13,500 annually with employer matching contributions following strict guidelines.

Bottom Line

Not all 401(k) providers are created to meet the demands of every type of client while some cover the most common needs. Choose a provider that makes it easy to establish and manage the account. You want to balance the cost with the investment options and advice received.

For those who need a provider that does a little more hand-holding through the process of owning a solo 401(k), check out ShareBuilder 401k. It is an experienced provider of 401(k) plans and has reasonable setup fees of $150 and monthly administrative fees of $25. ShareBuilder 401k keeps it simple so you can get back to earning.
