<p>A <strong>premium</strong> is the price an investor pays to purchase an options contract, giving the holder the right—but not the obligation—to buy (call) or sell (put) an underlying asset at a specified strike price before a set expiration date. The premium represents the cost of acquiring this right and is determined by factors such as the underlying asset’s price, volatility, time to expiration, interest rates, and dividends.</p>

<h2>How It Works</h2>
<p>When a trader buys an option, the seller (or writer) receives the premium as compensation for taking on the obligation that may arise if the option is exercised. The premium is paid upfront and is non‑refundable, regardless of whether the option is later exercised or allowed to expire.</p>
<p>Key components of the premium include:</p>
<ul>
<li><strong>Intrinsic value</strong> – the amount by which the option is in‑the‑money (for a call, underlying price minus strike price; for a put, strike price minus underlying price).</li>
<li><strong>Time value</strong> – the portion of the premium attributable to the remaining time until expiration, reflecting the probability that the option will become profitable.</li>
</ul>
<p>For example, a <a href="/NewSite/encyclopedia/call-option/" class="ency-link">call option</a> on a stock trading at $50 with a $45 strike price might have $5 of intrinsic value. If the market prices the option at $7 total, the extra $2 is time value, compensating for the chance the stock could rise further before expiration.</p>

<h2>Why It Matters</h2>
<p>The premium is central to options trading because it determines the breakeven point and potential profit or loss. A buyer must see the underlying move enough to offset the premium paid; otherwise, the option expires worthless and the loss equals the premium. Conversely, the seller’s maximum gain is the premium received, while risk can be substantial, especially for naked positions.</p>
<p>Understanding how premiums are priced helps traders evaluate strategies such as covered calls, protective puts, or spreads. For instance, an investor holding 100 shares of a company might sell a call option with a $2 premium to generate income, accepting the obligation to sell the shares at the strike price if the option is exercised.</p>
