Options Trading Cost Analyzer

What is Options Trading Cost?

Options trading cost is the sum of fees you pay to execute options trades. It usually has a fixed part (e.g. per-order commission) and a variable part (e.g. per-contract fee). Total cost = (Fixed per trade × Number of trades) + (Variable per contract × Contracts per trade × Number of trades). Using this total as your strategy's initial cost in a backtest makes results closer to real-world performance.

How to Use This Analyzer

1. Enter fixed cost per trade: Your broker's fee per order (e.g. $0.65 per trade).
2. Enter variable cost per contract: Per-contract fee (e.g. $0.01 per contract).
3. Enter contracts per trade: How many contracts you trade per round-trip (open + close).
4. Enter number of trades: Total round-trip trades (e.g. from a backtest or your expected frequency).
5. Use the total cost: Set it as the initial cost or commission in your strategy backtest so P&L reflects real costs.

Why Strategy Initial Cost Matters

Backtests often assume zero or flat commission. If your real costs are fixed + variable per contract, your live results can be worse than the backtest. By estimating total cost with this analyzer and entering it as the strategy's initial cost (or equivalent commission setting), you get a more realistic expectation of performance.
