Naked Option Margin Calculator

Join our FREE member web site

Estimate margin required for selling naked options. I use the formula at Interactive Brokers to estimate your margin.

There are two numbers calculated:
- Gross Maintenance Margin. This is what you have to keep in your brokerage account.
- Net Margin Required. This is your net cash requirement.

Broad based indexes use 15% vs 20% in the margin calculation
