What is a long call (or long put)?
Updated 6 June 2026 · by Theo Chen
A long call (or long put) is the simplest options trade: you buy one contract and pay a premium. That premium is the most you can lose — a defined-risk, leveraged bet on direction. A call is bullish; a put is bearish.
Want the exact breakeven, max loss, max profit and the move you need? Enter a strike and premium.
Open the Long Call & Long Put Calculator →Max loss, breakeven and profit
- Max loss = the premium paid × 100, lost only if the option expires at or out of the money.
- Breakeven = strike + premium for a call; strike − premium for a put.
- Max profit = unlimited for a call; for a put, (strike − premium) × 100, reached if the stock falls to zero.
The payoff diagram is the classic hockey stick: flat at the max loss until the strike, then turning up (a call) or already high and falling toward the strike (a put).
Buy the $100 call for $5 ($500 debit). Max loss $500 below the strike; breakeven $105; profit is unlimited above it.
The catch: time and volatility
A long option is the right way to take a defined-risk directional bet — but it has an expiration date and loses a little value every day (theta), faster as expiration nears. Buying when implied volatility is high also means overpaying, so a post-event IV crush can sink the trade even if the stock moves your way. The breakeven already includes the premium, so the move has to clear the strike plus what you paid. Want a bet on a big move in either direction? Buy both legs as a straddle.
The bottom line
A long call is a defined-risk bet on a rise where the most you can lose is the premium, but time decay and a drop in implied volatility can sink it even when the stock moves your way - it must clear the strike plus the premium, fast enough to beat the decay.
Frequently asked questions
What is a long call?
A long call is simply a bought call option: it gives you the right to buy 100 shares at the strike price until expiration. You pay a premium up front, and that premium is the most you can lose. If the stock rises well above the strike, the call gains in value — its profit is unlimited in theory. It is a defined-risk way to make a bullish, leveraged bet.
What is the maximum loss and breakeven on a long option?
The maximum loss is the premium you paid, times 100 per contract — lost only if the option expires at or out of the money. The breakeven is the strike plus the premium for a call, or the strike minus the premium for a put: the stock has to move at least that far before the trade is profitable at expiration.
What is the difference between a long call and a long put?
A long call is bullish — you profit when the stock rises past the strike plus the premium. A long put is bearish — you profit when it falls below the strike minus the premium. Both have the same shape: a fixed, limited loss (the premium) and a much larger potential gain. A call's upside is unlimited; a put's is large but capped, because a stock can only fall to zero.
Is buying a call better than buying the stock?
It is different. A long call costs a fraction of 100 shares and caps your loss at the premium, which gives leverage and defined risk — but it expires and bleeds time value, so the stock must move far enough, fast enough, to beat the premium and the decay. Shares never expire and never decay, but tie up far more capital.
When does a long call or put actually make money?
Only when the stock clears the breakeven before time decay and any drop in implied volatility erode the premium. The two hidden enemies are theta (daily decay, faster near expiration) and IV crush (volatility falling after an event you bought into). A long option can be directionally right and still lose if the move is too small or too slow.
