Option Margin Calculator
The Option Margin Calculator is an essential tool for options traders to assess the required margin for an options contract. Options trading involves complex calculations, and understanding margin requirements helps traders manage risk and ensure sufficient funds to cover potential losses.
Formula
The formula to calculate the option margin (OM) is:
OM = (OP ∗ NS ∗ MC) + (NS ∗ PC)
Where:
- OM is the Option Margin.
- OP is the Option Price.
- NS is the Number of Shares.
- MC is the Maintenance Coefficient.
- PC is the Premium Credit.
How to Use
- Enter the option price (the price of one option contract).
- Input the number of shares in the contract.
- Provide the maintenance coefficient, which varies by broker and is typically a set percentage.
- Enter any premium credit if applicable.
- Press “Calculate” to find the required option margin.
Example
Suppose you have the following values:
- Option Price (OP): $2.50
- Number of Shares (NS): 100
- Maintenance Coefficient (MC): 0.20
- Premium Credit (PC): $50
Using the formula:
OM = (2.50 * 100 * 0.20) + (100 * 50) = $75 + $5000 = $5075
So, the option margin required would be $5075.
