How Fees Impact Different Strategies
Covered Calls (2 legs: buy stock + sell call)
For a single covered call, you're paying one options commission. At $0.65, this barely registers on a position worth thousands. Fee differences only matter if you're writing covered calls weekly across many positions.Iron Condors (4 legs)
A 1-lot iron condor costs $2.60 to open and $2.60 to close at $0.65/contract — $5.20 round trip. At tastytrade, it's $4.00 to open and $0 to close. At Robinhood, $0 total. For a trade collecting $100-200 in premium, commissions matter.Credit Spreads (2 legs)
$1.30 round trip at standard brokers. $2.00 to open and $0 to close at tastytrade. $0 at Robinhood.High-Frequency Scalping (many trades per day)
At 20+ round-trip trades per day, IBKR tiered pricing dominates. Even at $0.25/contract effective cost, you're saving hundreds per month versus $0.65 brokers.Platform Costs
| Broker | Desktop Platform | Real-Time Data | Level 2 |
Most brokers have eliminated platform fees entirely. The main paid add-on is Level 2 data, which some brokers include free while others charge a small monthly fee.
The Real Cost Calculator
To calculate your true monthly cost at any broker:
Monthly cost = (Contracts traded × Per-contract fee × 2) + Platform fees + (Average margin balance × Margin rate / 12)
That margin rate component is often the largest cost for sellers who carry positions. The difference between IBKR's 5.8% and E*TRADE's 10.6% on a $50,000 margin balance is $200/month.
Which Broker Is Actually Cheapest?
It depends on how you trade:
For most options traders making 10-30 trades per month, the fee differences across standard brokers amount to $20-50/month. Spend your energy finding better trades — a tool like OptionsPilot that identifies higher-probability setups will save you more than any commission savings.
