What Is an Options Premium? The Price Tag on Every Contract

The options premium is the number every other options concept hangs off — it's what you pay, what melts, and, for buyers, the most you can lose. This page unpacks it using the real contract documented in our free handbook. Research and education only — not financial advice.

The price tag on the contract

The options premium is what an option costs — the price the buyer pays and the seller collects. Everything else on the ticket describes what you're buying; the premium is what you pay for it. Take the contract our handbook is built around, written the way traders write it: RIVN 7/17 $17 PUT @ $0.91. Five pieces: the underlying stock (RIVN), the expiration (July 17), the strike price ($17), the type (put), and the premium ($0.91). That last number is the entire cost of entry.

The two sides of the trade treat it very differently. The buyer pays the premium and receives rights — the right to buy (call) or sell (put) 100 shares at the strike, with no obligation to do anything. The seller collects the premium and takes on the matching obligation. That asymmetry is why the premium doubles as the buyer's maximum loss, which we'll get to below.

Quoted per share, paid ×100

Here is the trap that catches nearly every beginner. Premiums are quoted per share, but one standard equity contract covers 100 shares. Real money is always the quote times 100:

Total cost = premium × 100 × contracts

So a $0.91 premium is not 91 cents. It's $91 per contract. The handbook trade bought 8 contracts: $0.91 × 100 × 8 = $728 of real money committed. Skim past the multiplier and you can buy ten times more risk than you meant to — it happens constantly.

The display gotcha. Some broker apps (as of July 2026, Robinhood's among them) show your average price per contract ("91.00") directly next to the live mark per share ("0.935"). Those are the same kind of number in different units — $0.91 × 100 = $91. Beginners see 91.00 next to 0.935 and read a 99% loss into a mark that actually sits a few cents per share above the entry. Convert both numbers to the same unit before you react.

What's inside the premium: intrinsic value + time value

Every options premium is exactly two ingredients — no more, no less:

Premium = intrinsic value + time value

Intrinsic value is the cash-it-in-right-now part. For a put, it's how far the stock sits below your locked-in selling price: strike − stock price. With RIVN at $16.63, the $17 put carried $17 − $16.63 = $0.37 of intrinsic value — you could exercise it and pocket that difference today. For calls it's the mirror image: stock − strike.

Time value is everything above intrinsic: what the market charges for the possibility that the stock keeps moving in your favor before the deadline. At the handbook's live snapshot the put was marked $0.935, so the split was $0.37 intrinsic + $0.565 time value — about 60% of the price was a bet on "maybe it keeps falling." That maybe-money is rented, not owned. It melts every day the stock stands still, and it melts fastest near expiry — the process traders call theta decay. At expiration, time value is zero by definition; only intrinsic remains.

Traders sort strikes by whether they hold intrinsic value right now — "moneyness." Using real RIVN put strikes with the stock at $16.63:

Put strike	Moneyness	What the premium is made of
$19	Deep in the money (ITM)	Mostly intrinsic — $2.37 of real value
$17	In the money (ITM)	$0.37 intrinsic + time value
$16.50	At the money (ATM)	Nearly all time value
$15.50	Out of the money (OTM)	Zero intrinsic — 100% time value, on a timer

Break-even: the line the premium draws

The strike is where your right kicks in; the premium decides where the position actually turns profitable at expiry. For a bought put: break-even = strike − premium paid. In the handbook trade, $17 − $0.91 = $16.09. Between $16.09 and $17 lives a dead zone: the stock fell, the put finished in the money, and the position still lost — because the intrinsic value recovered didn't cover the premium paid. Judging a trade against the strike instead of the break-even is one of the most common beginner errors. Know your break-even before you click buy, not after.

Why the premium is a buyer's maximum loss

Because a bought option carries rights and no obligations, the worst case is fully defined the moment you pay: the contract expires worthless and you lose the premium — all of it, but only it. No margin call, no owing more than you put in. In the handbook example, the hypothetical worst case was knowable to the dollar before entry: if RIVN had finished at or above $17 at expiry, the entire $728 premium would have gone to zero.

"Capped" cuts both ways. Risk limited to the premium sounds comforting until you understand that options routinely go to zero. Losing 100% of the premium is a normal, common outcome — not a freak accident. The honest way to read the cap: the premium is the amount you should be fully prepared to watch vanish.

Option sellers live in a different world. They keep the premium if the contract expires worthless, but their obligation can produce losses far larger than the premium collected. That's why selling options is a separate discipline with its own risk rules — and why most beginners start on the buying side, where the math of maximum loss is simple.

The other cost: the bid–ask toll

Options quote two prices. The bid is what you receive when you sell; the ask is what you pay when you buy; the gap is the spread — a toll charged on the way in and again on the way out. The handbook contract quoted $0.92 bid / $0.95 ask: a $0.03 spread, roughly $3 per contract each way, on a busy strike with 5,296 contracts of open interest. That's what a tight, liquid market looks like. On a dead strike, the spread can run 20–30% of the entire premium — you're down double digits the second the fill lands. Before paying any premium, check what it costs just to change your mind.

How a research desk handles premium

At ClaudeQuantAlgo, every options idea that survives the full-market scan, catalyst check, adversarial review, and liquidity screen is posted as a trigger-based card — entry trigger, TP1/TP2, stop, and time-stop — before the move, to a public, timestamped record. That record is a paper/model desk (no real money), losses stay on the board, and corrections are posted in the open. The premium math on this page is the foundation for reading those cards: per-share quotes, ×100 sizing, stops defined as a fraction of premium paid. For the full beginner walkthrough — built on the same real RIVN contract quoted throughout this page — Options, In Plain English has a free chapter.

Common questions

Why is an options premium quoted per share but charged ×100?

One standard equity option contract controls 100 shares, so the quoted per-share price is multiplied by 100 when money actually moves. A $0.91 quote means $91 per contract; eight contracts cost $728. Total cost = premium × 100 × contracts.

Can I lose more than the premium I paid?

Not as a buyer of a call or put — you hold rights, not obligations, so the premium is your maximum loss. But losing 100% of the premium is a common, normal outcome, not a rare one. Option sellers are different: their obligations can produce losses larger than the premium they collected.

What is the difference between intrinsic value and time value?

Intrinsic value is what the option would be worth if exercised right now (put: strike − stock price; call: stock − strike; never below zero). Time value is everything above that — the market's charge for remaining possibility. Time value decays to zero by expiration, so an option can lose money even when the stock doesn't move.

Why did my option lose value when the stock didn't move?

Two forces work on the premium besides price: time value melts a little every day (theta decay), and a drop in implied volatility deflates the "drama" priced into the contract. Both can drain a premium while the stock stands perfectly still.

Is a cheap options premium a bargain?

Usually it's cheap for a reason — far out of the money, short-dated, or illiquid, meaning the price is 100% time value with low odds attached. Judge a contract by its break-even (strike adjusted by premium) and its bid–ask spread, not by the size of the sticker.
