Option Premium Explained

Learn what option premium is, how it relates to intrinsic value, extrinsic value, breakeven, IV, and contract multiplier.

Quick answer

Option premium is the market price of the option. For U.S. equity options, one listed price usually applies to 100 shares, so $2.00 means about $200 per contract.

Before risking money

Know the max loss and the dollar amount after the 100-share multiplier.

Paper trade the exact contract and record bid, ask, midpoint, IV, and Greeks.

Avoid contracts with wide spreads, stale quotes, or thin open interest.

Understand expiration and what happens if you hold too long; short-option positions add assignment risk.

Lesson

Plain-language concept

Premium is what the buyer pays and the seller receives. It can include intrinsic value plus extrinsic value. Extrinsic value reflects time, volatility, and supply/demand.

Lesson

What can go wrong

A low premium can still be expensive if the chance of payoff is low or the bid/ask spread is wide. A high premium can reflect high implied volatility, not just opportunity.

Lesson

When to use CuteMarkets data

Use quote and chain data to separate bid, ask, midpoint, last trade, IV, and Greeks before deciding whether a displayed premium is meaningful.

Numeric example

Multiplier example

Setup

Displayed premium: $3.25
Standard multiplier: 100
Contracts: 2

Outcome

One contract costs about $325.
Two contracts cost about $650 before fees and spread impact.

Always multiply by contract size before thinking about risk.

FAQ

Common beginner questions

Is premium the same as max loss?

For a long option, premium paid is usually the max loss before fees. For sellers, risk can be much larger.

Why does premium change?

Premium changes with stock price, time, implied volatility, rates, dividends, and market liquidity.

What is breakeven?

Breakeven is the underlying price at expiration where intrinsic value equals the premium paid.
