Option Turnover

While trading in options, you might have heard about turnover, especially the sellers whose options trading margin depends on the turnover value. Also, the turnover value is useful in calculating brokerage and taxes. In all, turnover is the primary parameter for other option calculation, but how to calculate option turnover for income tax and other taxes?

In this article, let’s understand the concept of calculating option turnover value.

What is Option Turnover?

After the SEBI Margin Rule, Sept 2021, most of the traders have shifted towards options trading. This could be easily determined by analyzing the turnover value data on NSE where the option turnover value in equity alone is approximately 8 lakh crores in the month of March 2023.

In general,

Turnover = (Buying Value * Lot Size) – (Selling Value * Lot Size)

This helps in determining the profit or loss which is the total turnover value of the trade.

In the case of options, however, one more parameter is added to determine the turnover value. Hence,

Turnover in Options Trading = (Buying Value * Lot Size) – (Selling Value * Lot Size) + Sell Value

For turnover calculation in options trading, you will need to keep track of all of your trades over a given period with the following information:

  • The date of the trade
  • The type of option (call or put)
  • The strike price of the option
  • The expiration date of the option
  • The premium you paid or received for the option
  • The number of contracts traded

Once you have this information, you can calculate the total value of your trades during the period by adding up the premiums paid or received for each trade.

Option Turnover Calculation Example

To calculate turnover, you need to follow these steps:

  1. Premium of Selling
    Determine the absolute value of the premium received from selling options contracts during the period under consideration.
  2. Premium for Buying
    Determine the absolute value of the premium paid for buying options contracts during the same period.
  3. Total Premium
    Find the sum of the total premium trade, i.e. premium for bought contracts and premium received for sold contracts.
  4. Lot Size 
    The lot size refers to the number of units of the underlying asset that is represented by one options contract.
  5. Turnover Calculation
    The turnover is then calculated as the total premium traded multiplied by the lot size of the contract.
