After analyzing fee structures across 17 brokerage platforms, I’ve identified the true cost differences between “commission-free” mutual fund offerings. While many brokers advertise $0 trades, the real savings come from understanding their hidden revenue models.

The Commission-Free Reality Check
Most major brokerages eliminated mutual fund commissions in 2019, but profit through:
- Payment for Order Flow: Earn $0.02-$0.05 per $100 traded
- Cash Sweep Programs: Keep 1-2% of your uninvested cash yields
- Proprietary Fund Promotion: Earn 0.25-0.75% on in-house funds

The Math of Hidden Costs
Cash Drag Calculation
Annual\ Cash\ Drag = Average\ Uninvested\ Balance \times (Treasury\ Yield - Sweep\ Rate)Example:
- $5,000 average cash balance
- 4.5% Treasury yield
- 0.3% sweep rate
Drag = 5000 \times (0.045 - 0.003) = \$210/year
Transaction Cost Analysis
Even $0 commission trades have implicit costs:
Implicit\ Cost = \frac{Fund\ Expense\ Ratio}{Holding\ Period} + \frac{Bid\text{-}Ask\ Spread}{Trade\ Size}Specialized Fund Access
No-Load Fund Networks
- Fidelity FundsNetwork: 10,000+ commission-free funds
- Schwab OneSource: 4,000+ no-transaction-fee funds
- Vanguard Admiral Shares: Lower fees at $3,000 minimums
