Bear Put Spread - A Defined-Risk Way to Bet on a Decline

In this lesson
Set up a bear put spread, calculate its maximum profit, maximum loss and break-even, and compare it with buying a put outright.
A bear put spread is a bearish options strategy that buys one put and sells another put on the same stock with a lower strike and the same expiration. It is a debit spread: you pay to open it, and that net debit is the most you can lose. The sold put lowers the cost and raises the break-even, and in exchange it caps the profit at the difference between the strikes minus the debit.
It is the mirror image of the bull call spread: same structure, built with puts, pointed down. If you know the long put from Put Options Explained, you already know the leg that does the work.
How does a bear put spread work?
You buy a put at a higher strike (usually at or near the stock price) and sell a put at a lower strike, one contract each:
- The long put is your bearish bet. It gains as the stock falls.
- The short put is sold to help pay for it. In exchange, you give up every dollar the stock falls below its strike.
The short strike works as your target. Below it, the long put keeps gaining, but the short put loses the same amount, so the spread's value at expiration stops at the width. The Options Industry Council (OIC) describes the strategy the same way.
Worked example
XYZ 50/45 bear put spread, 45 days to expiration
XYZ trades at $50. You expect it to drift down toward $45 over the next six weeks.
- Buy the XYZ 50 put for $1.96.
- Sell the XYZ 45 put for $0.37.
- Net debit: $1.96 - $0.37 = $1.59 per share, or $159.
At expiration:
The premiums are model prices from the free calculator's defaults (30% implied volatility), not real quotes, and the figures ignore fees.
Illustrative and hypothetical. The ticker and prices are invented for teaching, and the figures exclude commissions, fees, margin interest and taxes, which reduce real results. Past or hypothetical outcomes do not indicate future results.

Profit or loss at expiration
What is the max profit, max loss and break-even of a bear put spread?
Each one in a sentence, per spread:
- Maximum loss is the net debit times 100: $1.59 x 100 = $159, if XYZ is at or above the long strike at expiration.
- Maximum profit is the strike width minus the net debit, times 100: ($5 - $1.59) x 100 = $341, if XYZ is at or below the short strike at expiration.
- Break-even at expiration is the long strike minus the net debit: $50 - $1.59 = $48.41.
You risk $159 to make up to $341. XYZ has to fall about 3.2% to break even and 10% to earn the maximum.
Is a bear put spread better than buying a put?
Compare it with the 50 put bought alone for $1.96:
- Cost: $159 for the spread versus $196 for the put.
- Break-even: $48.41 versus $48.04. The spread starts paying 37 cents sooner.
- At $45: the spread makes $341, the put $304.
- At $42: the put makes $604; the spread is still at $341. A sharp fall favors the put.

So the bear put spread suits a moderately bearish view with a target near the short strike. If you are hedging against a crash, or expect a large drop, the put alone keeps the downside payoff open. Protective Puts in Depth - Insuring Shares You Own covers using puts as insurance on shares you own.
How is a bear put spread different from a bear call spread?
Both are bearish verticals with a fixed maximum loss, but they make money in different ways:
A debit spread needs a move; a credit spread needs the absence of one. The next lesson, Credit Spreads Explained, covers the bear call spread in full.
What are the risks of a bear put spread?
- Early assignment on the short put. The OIC's bear put spread page notes that early assignment is possible at any time but generally happens only once the short put is deep in the money. If you are assigned on the 45 put, you buy 100 shares at $45, which takes $4,500 of cash or margin, even though your long 50 put still lets you sell them at $50. The loss stays capped, but the same OIC page warns that using the long put to cover the assignment means financing the stock for one business day. How your account handles that depends on your broker.
- Expiration near the short strike. If XYZ closes right around $45, it is unclear whether the short put will be assigned. Closing the spread before the final day avoids an unexpected stock position over the weekend.
- Fees and fills. Two legs, two sets of commissions and fees, and two bid-ask spreads. Enter the spread as one multi-leg limit order.
Check your understanding
You buy an XYZ 60 put for $2.80 and sell the 55 put for $1.05. What are the net debit, the maximum profit, the maximum loss and the break-even?
Show answer
Net debit: $2.80 - $1.05 = $1.75, or $175. Maximum loss: $175. Maximum profit: ($5 - $1.75) x 100 = $325. Break-even: $60 - $1.75 = $58.25 at expiration.
In the 50/45 example, XYZ ends at $46 at expiration. What is the profit or loss?
Show answer
The 50 put is worth $4.00 and the 45 put expires worthless, so the spread is worth $4.00. After the $1.59 debit, that is a $241 profit: ($4.00 - $1.59) x 100.
Which costs more to open and which has the higher break-even: the 50/45 bear put spread or the 50 put alone?
Show answer
The 50 put alone costs more ($196 versus $159). The spread has the higher break-even ($48.41 versus $48.04), so it starts making money after a smaller fall, but it stops gaining below $45.
Key takeaways
- A bear put spread buys a put and sells a lower-strike put with the same expiration, for a net debit.
- Maximum loss is the debit; maximum profit is the strike width minus the debit; break-even is the long strike minus the debit.
- Compared with the put alone, it costs less and breaks even sooner, but gives up all gains below the short strike.
- It fits a moderately bearish view; a bear call spread is the credit-spread alternative that profits if the stock just stays down.
- Early assignment on the short put does not change the cap, but it can require cash or margin for the shares until you close.
Common questions
What is a bear put spread?
A bear put spread is a bearish options position that buys one put and sells another put with a lower strike and the same expiration. You pay a net debit, which is the most you can lose, and the most you can make is the difference between the strikes minus that debit.
How do you calculate the break-even of a bear put spread?
Subtract the net debit from the higher (long) strike. Buying the 50 put and selling the 45 put for a $1.59 net debit breaks even at $50 - $1.59 = $48.41 at expiration, before fees.
What is the difference between a bear put spread and a bear call spread?
Both profit if the stock falls, and both have a fixed maximum loss. A bear put spread is a debit spread: you pay up front and need the stock to fall. A bear call spread is a credit spread: you are paid up front and profit if the stock simply stays below the short strike.
Can you lose more than you paid on a bear put spread?
Not at expiration: the worst case is losing the net debit, because the spread is never worth less than zero. Early assignment on the short put does not change that cap, but it can leave you holding shares you need cash or margin to carry until you close the position.
