Vertical Spreads
Learn how same-expiration options at different strikes create defined-risk debit or credit spreads. Includes a worked example, risks and primary sources.
A vertical spread combines two options of the same type and expiration at different strikes. One leg is bought and the other sold, creating a defined maximum gain and loss at expiration. Debit spreads pay to enter; credit spreads receive premium, but both remain sensitive to execution, volatility and assignment.

Definition and mechanics
Calls or puts can form bullish or bearish verticals. The long leg limits the short leg’s risk, while the short leg reduces cost or creates a credit. Maximum outcomes depend on strike width and net debit or credit.
How to evaluate it
Record the option type, expiration, long strike, short strike and net debit or credit. Use the strike width to calculate maximum gain, maximum loss and breakeven, then stress-test price, time and volatility before expiration. Multi-leg liquidity, partial fills, early assignment and expiration near the short strike can alter the practical result.
Worked example
A $50/$55 call debit spread bought for $2 has a $200 maximum loss and a $300 maximum expiration gain before fees when the spread reaches its $5 width.
Risks and limitations
- Defined risk can still equal the full debit or the strike width minus credit, and multi-leg fills can differ from theoretical prices.
- Options involve risk and can lose part or all of the capital committed. Multi-leg positions also introduce execution, assignment and management complexity.
Common misconception
Reality check
Defined risk does not mean high probability or easy management; it only places a boundary on the modeled expiration loss.
