Betterment vs Vestwell

Comparison Details

Betterment vs Vestwell: which 401(k) administrator is the better fit? Betterment LLC and Vestwell are both New York-based fintech administrators built to simplify retirement plan operations through modern recordkeeping, compliance support, and payroll connectivity. While both can serve as a technology-forward partner for 401(k) plans, they differ meaningfully in plan coverage, fiduciary service mix, pricing structure, and overall scale. Plan types supported Betterment: Supports 401(k) and Solo(k) plans through Betterment at Work. Vestwell: Supports 401(k) , 403(b) , and Solo(k) , making it a stronger option if you need 403(b) administration (common for nonprofits and certain public-sector employers). If your organization may expand into additional plan types (like 403(b)), Vestwell has the edge on breadth. If you’re focused on a streamlined 401(k) experience with a well-known consumer fintech brand, Betterment is often compelling. Fiduciary and compliance capabilities Betterment services: Recordkeeping, compliance, plan design, and 3(38) investment fiduciary support. Betterment also lists fiduciary audit support, which may appeal to sponsors who want additional oversight and documentation. Vestwell services: Recordkeeping, compliance, and both 3(21) and 3(38) fiduciary services—useful if you want flexibility between co-fiduciary guidance (3(21)) and discretionary management (3(38)). Both providers position themselves as compliance-forward administrators. Vestwell’s inclusion of 3(21) can be a differentiator for employers who want advisor-led investment support without fully outsourcing discretion. Payroll integrations and admin experience Payroll connectivity is often the make-or-break factor in day-to-day administration. Betterment: Highlights integrations with 350+ payroll providers , plus ongoing monitoring and annual testing designed to reduce sponsor workload. Vestwell: Emphasizes extensive payroll integrations and a digital-first recordkeeping platform, with added accessibility features like multi-language support. If your workforce is diverse or you need multilingual participant experiences, Vestwell’s language support may be a practical advantage. If your priority is broad payroll compatibility at scale, Betterment’s stated 350+ integrations is a strong signal. Pricing comparison (base + per-employee fees) Both providers publish tiered pricing, but the mix of base fees and per-employee fees changes the economics depending on headcount. Betterment Essential: $100/month base + $5/employee/month Betterment Pro: $150/month base + $7/employee/month Vestwell Starter(k): $39/month base + $8/employee/month (setup fee $0) Vestwell Workplace: $80/month base + $8/employee/month (setup fee $0) Vestwell Plus: $125/month base + $8/employee/month (setup fee $0) How to interpret this: Vestwell can look attractive for very small teams due to the low base fee, but its per-employee fee is higher than Betterment’s Essential tier. Betterment may become more cost-efficient as headcount grows, particularly if you fit the Essential tier feature set. Scale, footprint, and track record Betterment: Founded 2009, ~466 employees. Reported (2025) ~2,000 401(k) clients and $30M 401(k) AUM in the provided dataset. Vestwell: Founded 2016, ~350 employees. Reported (2025) ~12,086 401(k) clients, $34.9B AUM, and 179,750 participants in the provided dataset. Based on the provided client stats, Vestwell operates at significantly larger 401(k) scale, which may matter if you value a platform proven across many employers and participants. Betterment’s longer operating history and consumer brand recognition can still be a deciding factor for sponsors prioritizing a familiar financial wellness experience. Choosing between Betterment and Vestwell Choose Betterment if you want a modern 401(k) with strong payroll connectivity, plan design support, and potentially lower per-employee costs at scale. Choose Vestwell if you need 403(b) support, want both 3(21) and 3(38) options, or prefer a platform with very large reported plan scale and multilingual capabilities. For the best decision, model total monthly cost at your current (and expected) headcount, confirm payroll compatibility, and compare fiduciary service levels (3(21) vs 3(38)) against your internal bandwidth for investment oversight.
