Tastytrade Commissions for Iron Condors: Complete Breakdown
Tastytrade charges $1.00 per contract to open options and $0.00 to close them. For a 1-contract iron condor (4 legs), the round-trip commission is $4.00 — all paid at entry, nothing at exit. This guide breaks down the exact math across different contract sizes and explains how commission drag affects the net edge of a systematic iron condor strategy.
Tastytrade Commission Structure
Tradematic executes iron condors through Tastytrade's API. The commission structure you pay:
- To open: $1.00 per contract per leg (capped at $10 per leg)
- To close: $0.00 per contract (free to close)
- Assignment/exercise fee: $0 for Tastytrade customers
- Regulatory fees: Small SEC/FINRA fees apply (typically $0.01–$0.02 per contract)
The key feature: closing trades are completely free. This encourages active management — you can close early to take profit or cut losses without additional commission friction.
Iron Condor Commission Math
An iron condor has 4 legs (bull put spread + bear call spread). Each leg incurs the per-contract commission at opening.
1 Contract Iron Condor
| Action | Legs | Contracts | Commission |
|---|---|---|---|
| Open | 4 | 1 each | $4.00 |
| Close | 4 | 1 each | $0.00 |
| Round trip total | $4.00 |
5 Contract Iron Condor
| Action | Legs | Contracts | Commission |
|---|---|---|---|
| Open | 4 | 5 each | $20.00 |
| Close | 4 | 5 each | $0.00 |
| Round trip total | $20.00 |
10 Contract Iron Condor
| Action | Legs | Contracts | Commission |
|---|---|---|---|
| Open | 4 | 10 each | $40.00 |
| Close | 4 | 10 each | $0.00 |
| Round trip total | $40.00 |
Note: The $10 per-leg cap means that at 10+ contracts, each leg is capped at $10 regardless of contract count. Above 10 contracts, your opening commission per leg stays at $10.
Commission as a Percentage of Premium
The key question for systematic traders: how much does commission drag reduce your net edge?
Assume a typical iron condor collecting $1.00 net credit per contract:
| Contracts | Premium Collected | Opening Commission | Commission % of Premium |
|---|---|---|---|
| 1 | $100 | $4.00 | 4.0% |
| 5 | $500 | $20.00 | 4.0% |
| 10 | $1,000 | $40.00 | 4.0% |
| 20 | $2,000 | $40.00 (capped) | 2.0% |
| 50 | $5,000 | $40.00 (capped) | 0.8% |
At small contract sizes (1–10), commission is a flat 4% drag on premium. Once you hit the cap (10 contracts per leg), the commission percentage drops as you trade larger sizes.
What This Means for Your Strategy
4% commission drag is meaningful but does not eliminate the statistical edge of systematic iron condors:
- A typical 45 DTE iron condor has a win rate of approximately 70–75%
- Expected value before commissions: roughly $0.15–$0.25 per dollar at risk
- Commission drag of 4% reduces premium by $0.04 per $1.00 collected
- Net edge remains positive — commissions reduce but don't eliminate it
The free-to-close structure is particularly valuable: if you close at 50% of max profit, the $0 closing commission means your full profit is captured without additional cost.
Reducing Commission Impact
Practical approaches to managing commission drag:
- Trade larger contract sizes — above 10 contracts per leg, the per-leg cap kicks in and your commission percentage drops
- Use the free-to-close policy — always close rather than hold to expiration to capture profit without closing commission
- Avoid over-trading — each new position costs $4 minimum; be selective about entry timing
- Automate entry and exit — Tradematic executes iron condors as single combined orders and manages exits systematically, avoiding unnecessary commissions from manual errors or partial fills
Frequently Asked Questions
Does Tastytrade charge a commission to close options that expire worthless? No. If an option expires worthless (out of the money at expiration), there is no closing commission — the position closes automatically with no fee.
Is there a commission cap for the entire iron condor or per leg? The $10 cap applies per leg. A 4-leg iron condor at 10+ contracts has a maximum opening commission of $40 (4 legs × $10 cap per leg).
Are there any account fees beyond commissions? Tastytrade charges no inactivity fees, platform fees, or data fees for standard accounts. Small regulatory fees (exchange, SEC, FINRA) typically amount to a few cents per trade. See FINRA's guide to understanding brokerage fees for context on standard regulatory charges.
How does Tastytrade compare to Tradier on commissions? Tastytrade: $1/contract open, $0 close. Tradier: $0.35/contract both ways. For traders below 10 contracts per leg, Tradier is cheaper per round trip. Above 10 contracts, the Tastytrade cap makes it more competitive.

Conclusion
Tastytrade's commission structure suits systematic iron condor traders: $4 per round trip at 1 contract, scaling to a $40 cap per round trip at 10+ contracts. The free-to-close model is particularly valuable for disciplined position management.
Commission drag of 4% at small sizes is real but manageable — it reduces but does not eliminate the statistical edge of systematic premium selling.
