Compare the complete trade, including every leg
An options commission quote can be per contract, per order or per opening leg, so four apparently similar prices can produce different bills. A two-leg spread opened and later closed uses four contract transactions for every spread unit. Exchange, clearing and regulatory charges may apply in addition to the broker's headline commission.
The comparison below concerns standard U.S. stock and ETF options in eligible accounts, checked September 12, 2026. Index products, negotiated rates and different regional broker entities can have different charges. It is a schedule comparison, not a tested ranking of execution quality or a claim that an account will be approved.
Read the rate and its exceptions together
| Broker | Published commission structure | Condition affecting comparison |
|---|---|---|
| Schwab | $0 online base plus $0.65 per contract | Broker-assisted and other applicable fees are separate |
| Fidelity | $0 online base plus $0.65 per contract | Buy-to-close orders priced $0.65 or less per contract have no contract fee |
| IBKR Pro | At the first monthly tier: $0.25, $0.50 or $0.65 per contract depending on premium | $1 minimum per order; premium and volume tiers matter |
| tastytrade | $1 per contract to open, capped at $10 per stock/ETF-options leg; $0 closing commission | Broad-based index options have no such cap; other transaction charges remain |
For IBKR Pro at up to 10,000 monthly contracts, the listed premium bands are below $0.05, from $0.05 to below $0.10, and at least $0.10. The $0.65 illustration below assumes the last band. A one-contract order in that band is subject to the $1 minimum, rather than costing $0.65. The U.S.-resident IBKR Lite program has a separate schedule.
Calculate an opening and closing example
Assume ten two-leg spreads are opened and all legs are later closed, with no special waiver. At $0.65 per contract each way, broker commission is 10 × 2 × 2 × $0.65 = $26. Under tastytrade's stock/ETF structure, opening commission is 2 × min(10 × $1, $10) = $20 and closing commission is $0. Both calculations exclude other charges.
At twenty spreads, those illustrative totals become $52 and $20, because the latter opening cap applies separately to each leg. At one spread, a per-order minimum can change the comparison. A fee table that only multiplies the opening quantity by the headline rate misses these differences. Check how a multi-leg order is billed in the actual preview.
A small price difference can outweigh commission
Assume two executions for ten standard contracts occur at premiums of $1.03 and $1.08. With a 100-share multiplier, the difference is $0.05 × 100 × 10 = $50. This is a hypothetical price comparison, not measured performance for any named broker. A cheaper posted commission does not establish a lower total purchase cost.
Record whether quotes are live, the available size, the net debit or credit and the limit price. A simulated fill cannot establish a live fill at the same price or quantity. Compare cancel/replace handling and how a multi-leg order could become partly filled. These operational questions can be evaluated without claiming a platform generates more profitable trades.
Check exercise and assignment before choosing an interface
FINRA's options guide explains broker approval, the usual 100-share standard contract, American-style exercise and assignment obligations. Approval levels and financial requirements differ by firm; there is no universal $25,000 income or fixed experience threshold that assures approval.
A standard $50-strike put assigned on ten contracts requires buying 1,000 shares for $50,000, before considering the premium received. A spread's intended maximum loss assumes its legs and settlement work as modeled; early assignment, separate exercise decisions or liquidation can create stock and funding exposure. A covered call still bears the underlying stock's downside and limits upside.
A practical comparison records the intended strategy's permission level, cash or margin requirements, exercise cut-off, expiration handling, assignment notifications and support channel. Options can create losses beyond the initial premium when obligations are sold. These mechanics belong beside the fee calculation because they determine whether the planned trade can actually be maintained and closed.
