Options Premium: Complete Guide to Understanding Option Prices

Options premium is the price you pay or receive for an options contract. It's determined by intrinsic value (how much the option is in-the-money) and extrinsic value (time value + implied volatility). The premium changes based on stock price, time until expiration, volatility, interest rates, and dividends. If you want to learn more on how the premium works, give this text below a few minutes of your time.

    Highlights
  • Two Components: Options premium consists of intrinsic value and extrinsic value. Intrinsic value is the amount an option is in-the-money, while extrinsic value comes from time remaining and expected volatility.
  • Premium Decay: Options lose value as expiration approaches due to theta decay. This time decay accelerates in the final 30-45 days before expiration, which is why wheel strategy traders target this period.
  • Volatility Impact: Higher implied volatility means higher premiums. When market uncertainty increases, options become more expensive because sellers demand more compensation for taking on greater risk.

What Is Options Premium?

Options premium is the price of an option contract. It’s quoted per share, but since each contract controls 100 shares, you multiply by 100 to get the actual cost.

Example:

  • Option premium: $3.50 per share
  • Actual cost per contract: $3.50 × 100 = $350

Buyers pay premium to purchase the right (but not obligation) to buy or sell stock. Sellers receive premium for taking on the obligation to fulfill the contract if exercised.

Premium is paid/received immediately when the trade executes.

Components of Premium

Every option premium consists of two parts:

Premium = Intrinsic Value + Extrinsic Value

A comprehensive diagram illustrating intrinsic value and extrinsic value components of option premium, explaining what is option premium and how does option premium work when trading options. The visual breaks down option premium into intrinsic value—the immediate profit if exercising an option—and extrinsic value, representing time and volatility factors affecting option pricing. Traders analyzing this option diagram understand that intrinsic value only exists for in-the-money options, while extrinsic value affects all options contracts and decays as expiration approaches. Understanding these option premium components helps options traders calculate fair option premium before entering positions. This explanation of how does option premium work demonstrates why option premium varies across different options strikes and expirations, enabling smarter trading decisions when buying or selling options based on combined intrinsic value and extrinsic value analysis.

Intrinsic Value

Intrinsic value is the real, tangible value of an option—how much it would be worth if exercised right now. For calls: Intrinsic Value = Stock Price – Strike Price (if positive) For puts: Intrinsic Value = Strike Price – Stock Price (if positive)

Example:

  • AAPL at $180
  • $170 call intrinsic value = $180 – $170 = $10
  • $175 put intrinsic value = $0 (stock above strike)

OTM options have zero intrinsic value—their entire premium is extrinsic.

Extrinsic Value (Time Value)

Extrinsic value is everything else—the “hope value” that the option might become more valuable before expiration.

Extrinsic value includes:

  • Time value: More time = more opportunity = more value
  • Volatility value: More uncertainty = more potential = more value

Extrinsic Value = Premium – Intrinsic Value

Example:

  • AAPL $170 call trading at $12
  • Intrinsic value: $10 ($180 – $170)
  • Extrinsic value: $2 ($12 – $10)

As expiration approaches, extrinsic value decays to zero. This is how options sellers make money.

A detailed table displaying intrinsic value and extrinsic value components of option premium, explaining what is options premium and how does options premium work when trading options.This breakdown shows how to pick strike price by analyzing strike price levels for intrinsic profit potential versus time decay premium. Intrinsic value indicates when sellers get assigned because deep ITM strike price contracts force assignment. Understanding extrinsic value helps avoid got assigned scenarios by selecting strikes where assignment probability remains low while maximizing time premium collection.

What Affects Premium?

Five main factors drive option premiums:

1. Stock Price vs Strike Price (Intrinsic Value)

The closer to (or further into) the money, the higher the premium.

More ITM = Higher premium (more intrinsic value) More OTM = Lower premium (no intrinsic value)

2. Time to Expiration

More time = more extrinsic value = higher premium.

45 DTE option: Higher premium 7 DTE option: Lower premium (same strike)

Time decay (theta) erodes this value daily.

3. Implied Volatility (IV)

Higher IV = higher premiums. IV reflects expected future movement.

High IV (earnings, news): Expensive options Low IV (calm markets): Cheap options

This is the most controllable factor for traders:

  • Sellers: Sell when IV is high to collect more premium
  • Buyers: Buy when IV is low to pay less

4. Interest Rates

Higher interest rates slightly increase call premiums and decrease put premiums.

Minor factor—usually ignored by retail traders.

5. Dividends

Expected dividends reduce call premiums and increase put premiums slightly.

Important for: Covered call sellers near ex-dividend dates (early assignment risk).

Premium and the Greeks

The Greeks measure how premium changes with different factors:

Greek Measures Effect on Premium
Delta Price change per $1 stock move Higher delta = premium changes more
Theta Time decay per day Premium decreases daily
Vega IV sensitivity Higher IV = higher premium
Gamma Delta acceleration Premium more sensitive near expiration

Theta: The Premium Killer (or Profit Engine)

Theta represents daily time decay:

For buyers: Theta is negative—you lose value every day

For sellers: Theta is positive—you gain value every day

Comprehensive visualization demonstrating how theta decay accelerates as options approach expiration, showing the critical relationship between time decay and option value erosion across different timeframes. This detailed chart from QuantWheel illustrates theta patterns affecting options trading positions, with the vertical axis measuring daily decay in dollars from $10 to $100, while the horizontal axis tracks days to expire from 90 days down to zero. The graph clearly depicts three distinct phases of time value erosion: slow decay at $10 per day when 90 days remain, moderate decay increasing to $20 daily at the 30-day mark, and aggressive decay reaching $50 per day as contracts near their final days before expiration. Traders and investors can observe how premium deteriorates exponentially rather than linearly, a fundamental concept in options pricing models that significantly impacts strategy selection and portfolio management decisions when dealing with derivatives positions and risk exposure.

Example: Option with theta of -0.05

  • Loses $5 per day (per contract) just from time passing
  • If stock doesn’t move, buyer loses $5/day
  • Seller gains $5/day

This is why options sellers have a mathematical edge.

Premium for Different Strategies

Detailed analytical chart illustrating option theta decay behavior across the moneyness spectrum, demonstrating how time decay rates vary significantly between OTM (out-of-the-money), ATM (at-the-money), and ITM (in-the-money) options contracts. This comprehensive QuantWheel visualization reveals that ATM options experience maximum theta decay, presenting the greatest opportunity for sellers implementing theta strategy positions, while the premium composition shifts dramatically based on strike price positioning relative to the underlying asset price. The graph displays five distinct moneyness levels with corresponding strike prices ranging from $70 (deep OTM) to $130 (deep ITM), showing how time value (cyan bars) dominates OTM and ATM positions while intrinsic value (green bars) increases for ITM options. Traders can observe the daily decay curve (pink line) peaking at the ATM position where options trading risk and theta sensitivity reach their maximum, while the total premium (red line) demonstrates an upward trajectory across the moneyness range, critical information for portfolio management and derivatives pricing analysis.

Buying Calls (Pay Premium)

You pay premium hoping stock rises significantly.

Considerations:

  • ATM calls: Higher premium, higher delta
  • OTM calls: Lower premium, lower probability
  • Long-dated: More expensive but more time

Goal: Stock rises enough that option gains exceed premium paid.

Buying Puts (Pay Premium)

You pay premium hoping stock falls or to hedge.

For hedging: Premium is like insurance cost For speculation: Need stock to fall enough to profit

Selling Cash-Secured Puts (Receive Premium)

You receive premium for agreeing to potentially buy stock.

Premium collected = Maximum profit Ideal conditions:

  • High IV (inflated premiums)
  • Stock you want to own
  • Strike below current price (OTM)

Selling Covered Calls (Receive Premium)

You receive premium for agreeing to potentially sell stock you own.

Premium collected = Extra income on holdings Ideal conditions:

  • High IV
  • Willing to sell at strike
  • Strike above current price (OTM)

How to Evaluate Premium

Premium Yield Calculation

  • For selling strategies, calculate the yield to compare opportunities:

Premium Yield = (Premium / Collateral) × (365 / DTE) Example: Sell $170 put for $3 (30 DTE)

  • Collateral: $17,000
  • Premium Yield: ($300 / $17,000) × (365 / 30) = 21.5% annualized

What’s a Good Premium?

For cash-secured puts:

  • Target: 1-2% per month (12-24% annualized)
  • Minimum: 0.75% per month to be worthwhile
  • Consider risk vs reward for each trade

For covered calls:

  • Target: 1-2% per month
  • Balance premium vs upside cap

Premium Red Flags

Very high premium usually means:

  • Earnings announcement coming
  • High uncertainty/risk
  • Stock is very volatile

Very low premium usually means:

  • Low IV environment
  • Far OTM strike
  • May not be worth the risk

Premium Strategies for Income

Notice how the 50% profit comes in less than half the time. This is the power of the 45-21 rule.

Premium is the price of an option contract. Buyers pay premium to purchase options; sellers receive premium for selling options. It’s quoted per share but paid per contract (multiply by 100).

Premium = Intrinsic Value + Extrinsic Value. Intrinsic value is the in-the-money amount. Extrinsic value depends on time to expiration, implied volatility, interest rates, and dividends.

The seller always keeps the premium, regardless of outcome. If the option expires worthless, the seller keeps it as profit. If exercised, the seller still keeps the premium but must fulfill their obligation.

Time decay (theta) causes extrinsic value to decrease daily. As expiration approaches, the “hope” that the option will become more valuable diminishes. At expiration, only intrinsic value (if any) remains.

For selling strategies, target 1-2% monthly return on capital (12-24% annualized). This balances income with probability of profit. Higher premiums often come with higher risk.
