Bear Put Spread Calculator

A bear put spread profits when the stock drops. It costs less than a straight put because you sell a lower-strike put to offset part of the premium.

How a Bear Put Spread Works

A bear put spread uses two put options on the same stock with the same expiration date. You buy a higher-strike put and sell a lower-strike put. The premium from selling the lower put reduces your cost.

The result is a defined-risk, defined-reward position that profits when the stock declines.

Example: A stock is at $100. You buy the $100 put for $4.00 and sell the $90 put for $1.50. Your net cost is $2.50 per share, or $250 total. If the stock drops below $90, your profit is $7.50 per share, or $750. If the stock stays above $100, you lose $250.

Maximum Profit, Maximum Loss, and Breakeven

Maximum profit: (Upper strike − lower strike − net debit) × 100. In the example: ($100 − $90 − $2.50) × 100 = $750.

Maximum loss: The net debit paid. $250.

Breakeven at expiration: Upper strike − net debit. $100 − $2.50 = $97.50.

When to Use a Bear Put Spread

A bear put spread works best when you're moderately bearish — expecting a decline of 2-5%, not a crash. It's also useful for hedging an existing long stock position with defined cost.
