1. Overview: Employee Fiduciary vs Vanguard 401(k)
Employee Fiduciary is a dedicated 401(k) recordkeeper that works exclusively with small businesses. They use a flat‑fee model and offer access to low‑cost Vanguard funds and other institutional‑class investments. Vanguard is the giant of low‑cost investing; their small‑business 401(k) plans are typically bundled with recordkeeping and administration, but the fee structure and investment lineup differ significantly from Employee Fiduciary.
Both aim to minimize costs, but they achieve it differently – one through flat fees and transparency, the other through economies of scale and a limited set of Vanguard‑only funds.
2. Fee Comparison: The Deciding Factor for Most Small Businesses
Fees are the most controllable factor in a retirement plan. Even a 0.5% difference in total plan costs can compound to tens of thousands of dollars over a decade.
| Fee Component | Employee Fiduciary | Vanguard Small Business 401(k) |
|---|---|---|
| Plan Setup Fee | $1,000 (one‑time) | $0 – $500 depending on complexity |
| Annual Administration Fee | $1,500 flat (for up to 30 participants; additional per participant fee above that) | $0 – $3,000+ (bundled with asset‑based fees) |
| Per‑Participant Fee | $30/year (if over 30 participants) | Often included in asset fee |
| Asset‑Based Fee | None (no wrap fee) | 0.15% – 0.35% of plan assets (recordkeeping + advisory) |
| Investment Expense Ratios | Institutional class Vanguard funds (0.02% – 0.10%) | Vanguard Admiral / Institutional funds (0.02% – 0.12%) |
💰 Real‑world cost example
For a 10‑employee business with $1M in plan assets:
Employee Fiduciary: $1,500 flat + $0 asset fee = $1,500/year.
Vanguard: $0 admin fee + 0.20% asset fee = $2,000/year.
Winner on cost: Employee Fiduciary for most small plans.
3. Investment Options: Where Your Money Goes
Both providers give you access to Vanguard’s market‑leading index funds. The difference lies in flexibility.
- Employee Fiduciary – Your plan can include Vanguard Institutional funds, plus a broad menu of other fund families (DFA, Fidelity, PIMCO, etc.). You can also add self‑directed brokerage accounts (SDBA) for participants who want individual stocks or ETFs.
- Vanguard – The plan menu is limited to Vanguard mutual funds and a handful of Vanguard target‑date funds. No access to non‑Vanguard funds unless you use a third‑party administrator (which adds cost).
If you want to offer a wide range of low‑cost funds or allow employees to invest in individual stocks, Employee Fiduciary provides more flexibility.
4. Plan Administration & Compliance
Both providers handle mandatory testing (ADP/ACP, top‑heavy), Form 5500 filing, and annual compliance. However:
- Employee Fiduciary – Their service is built around small businesses. They provide a dedicated account manager and handle all compliance in‑house. The platform includes participant portal, online enrollment, and investment education.
- Vanguard – Administration is generally streamlined but may require you to work with a third‑party advisor (unless you use their “Vanguard Small Business 401(k)” which is more of a packaged solution). Their participant experience is excellent but less personalized for the employer.
🎯 Best for hands‑off owners
If you want minimal involvement and strong compliance support, Employee Fiduciary’s dedicated team often edges out Vanguard’s more automated approach.
5. Plan Design Flexibility
Small businesses often need custom plan features: safe harbor contributions, profit sharing, eligibility exclusions, etc.
- Employee Fiduciary – Full flexibility to design a custom plan (traditional, safe harbor, age‑weighted profit sharing, etc.). They also support solo 401(k) plans for owner‑only businesses.
- Vanguard – Offers a limited set of plan designs. They tend to standardize plans to keep costs low. If you need complex allocations or custom vesting schedules, Vanguard may not accommodate.
If you plan to use profit sharing to maximize contributions for owners or key employees, Employee Fiduciary is the stronger choice.
6. Participant Experience & Education
Both providers give participants online access to manage their accounts. Vanguard’s participant portal is world‑class – clean, educational, and easy to use. Employee Fiduciary’s portal is functional but less polished. However, Employee Fiduciary offers free investment advice consultations to participants, which can be valuable for employees who are new to investing.
7. Which One Is Right for Your Business?
Choose Employee Fiduciary if:
- You want a flat fee with no asset‑based charges.
- Your plan has under $5M in assets (flat fee is especially cost‑effective).
- You need access to non‑Vanguard funds or a self‑directed brokerage option.
- You want a dedicated account manager and custom plan design.
Choose Vanguard if:
- You are a Vanguard loyalist and prefer a fully integrated Vanguard‑only solution.
- Your plan assets are large enough (>$5M) that the asset‑based fee may be lower than a flat fee (though still worth calculating).
- You value a polished participant website above all else.
- You have a very simple plan structure (no complex profit sharing).
📊 Quick decision matrix
- Assets under $1M → Employee Fiduciary wins on cost and flexibility.
- Assets $1M–$5M → Employee Fiduciary still typically cheaper unless you need Vanguard’s participant portal.
- Assets >$5M → Run the numbers; Vanguard’s asset fee may become more competitive, but Employee Fiduciary’s flat fee still caps out.
8. Common Pitfalls to Avoid
- Underestimating compliance risk – Both providers handle compliance, but Employee Fiduciary’s dedicated team can catch issues earlier for small plans.
- Choosing based solely on name recognition – Vanguard is a trusted brand, but for a small plan, the total cost may be higher than expected after all fees are added.
- Ignoring investment flexibility – If your employees or you want access to funds beyond Vanguard, Employee Fiduciary gives you that freedom.
