Free options break-even calculator. Find the exact stock price where your call or put option breaks even at expiration, including premium cost.
The Options Break-Even Calculator instantly shows you the exact stock price at which your call or put option position becomes profitable at expiration. Every options trade has a break-even point that accounts for the premium paid, and knowing that price before you enter the trade is essential for sound risk management.
Whether you are buying calls in anticipation of a rally or purchasing puts as a hedge, understanding your break-even stock price helps you set realistic profit targets and stop-loss levels. This calculator handles both single-leg calls and puts, giving you a clear picture of how far the underlying needs to move before your position turns profitable.
Break-even analysis is one of the first things professional traders evaluate before entering a position. It tells you the minimum move required just to recover the premium, helping you decide whether the expected move justifies the cost of the option. This awareness separates disciplined options trading from gambling.
Knowing your break-even price before placing an options trade helps you avoid overpaying for premium. If the break-even price requires a move that is unlikely within the option's time frame, the trade may not be worth the risk. This calculator provides instant clarity so you can compare strategies and strike prices side by side.
Call Break-Even = Strike Price + Premium Paid per Share Put Break-Even = Strike Price – Premium Paid per Share Total Premium Cost = Premium per Share × 100 × Number of Contracts Required Move (%) = ((Break-Even – Current Price) / Current Price) × 100
Result: Break-even at $154.50
You buy a call option with a $150 strike for $4.50 per share. The break-even price is $150 + $4.50 = $154.50. The stock must trade above $154.50 at expiration for you to profit. If the stock is at exactly $154.50, you recover the premium but make no profit. Below $154.50, you lose some or all of the $450 premium (1 contract × 100 shares × $4.50).
Break-even analysis is one of the first checks before buying an option. It tells you how far the underlying must move by expiration just to recover the premium paid.
For call options, the break-even is above the strike because the stock must rise enough to offset the premium. For put options, the break-even is below the strike because the stock must fall far enough to cover the premium. In both cases, premium is the variable that pushes the break-even away from the strike.
Compare the break-even price to the current stock price and to your time horizon. If the required move looks unrealistic for the remaining life of the option, the trade may not be attractive even when you are directionally correct.

This calculator applies the standard expiration break-even formulas for a single long option: strike plus premium for a call and strike minus premium for a put. It also multiplies the premium by contract size and contract count to show total premium at risk and the move required from the current stock price.
The break-even shown is an expiration break-even. Before expiration, market value can differ because the option may still contain time value.
The break-even price is the stock price at which an option position neither makes nor loses money at expiration. For calls, it is the strike price plus the premium paid. For puts, it is the strike price minus the premium paid. Any move beyond break-even is profit.
This calculator focuses on the core break-even formula using strike and premium. You can mentally add commission costs to the premium to get a more precise break-even. For example, if commissions add $0.05 per share to your cost, add that to the premium before calculating.
Yes. Before expiration the option retains time value, so the stock does not need to reach the expiration break-even price for the option to be worth what you paid. The expiration break-even is the worst case assuming no time value remains.
Higher implied volatility increases option premiums, which pushes the break-even price further from the current stock price. Lower implied volatility means cheaper premiums and closer break-even prices, but the expected move may also be smaller.
For a long put, the break-even is the strike price minus the premium paid per share. The stock must fall below this price at expiration for the position to be profitable. For example, a $100 put bought for $3 has a break-even of $97.
For spreads or straddles, calculate the net premium paid or received across all legs and then determine the price at which the net position value equals zero. This calculator handles single-leg positions; you can use the formulas as building blocks for complex strategies.
Break-even tells you the minimum stock move required just to recover the premium. Without this analysis, you might buy options that require unrealistically large moves in a short time frame, leading to consistent losses even when you predict direction correctly.
No. The break-even stock price is the same regardless of how many contracts you buy. More contracts increase your total premium cost and total profit or loss, but the per-share break-even remains strike plus or minus premium.
