Launch and Connect Systems
Once the plan is approved, AssetMark helps establish the operational framework, including participant setup, payroll integration, contribution processing, and coordination with third-party administrators when required.
Manage Investments and Fiduciary Oversight
Depending on the arrangement, AssetMark may provide investment advice or discretionary 3(38) fiduciary management. This includes monitoring investment options, conducting due diligence, and maintaining the plan’s investment strategy.
Support Participants and Sponsors
Employees access their accounts through digital tools to review balances, manage contributions, and make investment elections. Employers and advisors receive reporting and ongoing support to monitor plan performance.
AssetMark provides a flexible 401(k) framework that combines investment management, fiduciary support, and retirement technology to help advisors and employers deliver effective workplace retirement solutions.

AssetMark Fees

AssetMark’s fee structure for retirement plans is primarily asset-based, consisting of
- Platform fee to AssetMark Retirement Services and
- Advisory fee charged by the financial advisor overseeing the plan.
These are typically combined and paid from plan assets on a quarterly basis.
| Cost Component | Typical Cost | Who Receives It | What It Covers |
|---|---|---|---|
| AssetMark Platform Fee | ~0.20%–0.30%+ | AssetMark | Platform access, administration, custodial services, and brokerage support. |
| Advisor Fee | ~0.30%–0.50% | Financial Advisor | Fiduciary guidance, investment oversight, retirement planning, and participant support. |
| Investment Expenses | ~0.10%–0.80% | Fund Providers | Ongoing mutual fund or ETF operating expenses and portfolio management costs. |
| Recordkeeping / Admin | Often bundled | Provider / TPA | Participant recordkeeping, compliance testing, reporting, and plan administration. |
| Setup / Conversion | $500–$5,000 (if charged) | Provider / TPA | Initial plan setup, onboarding, conversion, and implementation services. |
Because many retirement-plan fees are asset-based, the total cost impact varies significantly by plan size.
The examples below demonstrate how advisory, platform, investment, and administrative costs may combine in practice.
| Plan Size | Assets | Estimated Total Cost | Approx. Cost % |
|---|---|---|---|
| Small | $500K | ~$5K–$8K/year | ~1.0%–1.5% |
| Mid | $5M | ~$50K–$65K/year | ~1.0%–1.3% |
| Large | $50M | ~$500K/year | ~1.0% or lower |
AssetMark provides fee schedules and required disclosures, but employers and plan sponsors should request a plan-specific proposal to understand the total expected costs for their retirement plan.
