How Do I Understand a Broker's Fee Schedule?

Explicit trading costs

Commissions are straightforward—a fixed or percentage-based charge per trade. Spreads are the difference between bid and ask prices; wider spreads cost you money on entry and exit. Some brokers quote one or both separately; others embed spreads into the price. Always ask for the typical spread in instruments you'll trade, not just the best-case scenario.

Account maintenance fees

Inactivity fees charge you for not trading within a period. Custody fees apply to holding securities. Data or platform fees cover real-time quotes or advanced tools. Account closure fees penalize early exit. Request a written breakdown and ask which fees apply to your account tier.

Hidden costs

FX conversion fees apply when you deposit or withdraw in a different currency. Dividend reinvestment might carry a fee. Margin interest rates vary by broker and balance size. Request a sample month of statements to see all charges applied to a typical account, then multiply annually to grasp the real cost.
