What Is Option Premium? A Simple Guide for Beginners. - Bangalore

Option premium is the price a buyer pays to the seller to purchase an options contract. It is the cost of obtaining the right, but not the obligation to buy or sell an underlying asset at a specified price before or on a particular date.

Importance of Option Premium:

• Cost of Trading: It is the amount paid by the option buyer to enter an options contract.
• Buyer’s Risk: The buyer's maximum loss is generally limited to the premium paid.
• Seller’s Income: The option seller receives the premium in exchange for taking on the contractual obligation.
• Market Factors: The premium depends on factors such as the underlying asset's price, strike price, time to expiry, volatility and interest rates.

Simple Example:

Suppose you buy a call option on a stock with an option premium of ₹10 per share. If the contract covers 100 shares, you pay ₹1,000 as the total premium.

If the option expires worthless, you lose the ₹1,000 premium. If the option becomes profitable, your profit depends on the option's value at expiry, after accounting for the premium paid.
