Vertical Spread
A vertical spread buys one option and sells another of the same type and expiry at a different strike. It caps both the maximum gain and the maximum loss; a bull call spread, for example, profits from a moderate rise at a lower cost than a plain call.
Buying a call outright can be expensive, and selling options naked can be dangerous. A vertical spread sits in between: you buy one option and sell another at a different strike, so part of the cost is paid for and the risk is capped. It is one of the most common building blocks in options trading. This entry explains the four types, the payoff maths and the trade-offs.

Vertical spreads in plain words
A bull call spread is a type of vertical spread: you buy one call and sell another at a higher strike to help pay for it.1
Its maximum loss is the net premium paid, and its maximum gain is the difference between the strikes minus that premium.1
The short leg carries the seller's obligation if it is assigned.2
How to set up a vertical spread, step by step
Pick a direction
Bullish or bearish on the underlying. See Options.
Choose calls or puts
Same type and same expiry for both legs.
Buy one strike
The option you want exposure to.
Sell another strike
To reduce the cost and cap the payoff.
Net debit or credit
Debit spreads cost money; credit spreads collect it.
Know your limits
Max gain and max loss are fixed at entry.
Worked examples
Example 1 — Bull call spread wins
+$320Buy the $60 call for $3.00, sell the $65 call for $1.20. Net debit $1.80. At expiry the stock is $68.
| Spread value | ($65 − $60) × 100 = $500 |
| Cost | $1.80 × 100 = $180 |
| Profit (maximum) | $500 − $180 = $320 |
Maximum gain is the high strike minus the low strike minus the net premium paid.1
Example 2 — Bull call spread loses
−$180Same spread, but the stock ends at $58, below both strikes.
| Both calls expire worthless | $0 |
| Loss (maximum) | −$180 |
However far the stock falls, the maximum loss on a debit spread is limited to the net premium paid at the start.1
Example 3 — Break-even
Break-even $61.80Same spread, net debit $1.80.
| Break-even | $60 + $1.80 = $61.80 |
| Reward-to-risk | $320 : $180 ≈ 1.8 : 1 |
Below the higher strike the spread behaves much like its long call alone; above it the gain is capped.1
The four vertical spreads
| Aspect | Outlook | Cash at entry |
|---|---|---|
| Bull call spread | Bullish | Debit |
| Bear put spread | Bearish | Debit |
| Bull put spread | Bullish | Credit |
| Bear call spread | Bearish | Credit |
When traders use vertical spreads
Cheaper directional bets
Lower cost than buying a single option. See Option Premium.
Defined risk
Maximum loss known in advance. See Risk Management.
High implied volatility
Selling one leg offsets rich premiums. See Implied Volatility.
Building blocks
Two verticals make an iron condor. See Iron Condor.
Advantages and disadvantages
Advantages
- Lower cost than a single long option.
- Defined maximum loss.
- Flexible for bullish or bearish views.
Disadvantages
- Capped profit.
- Two legs mean more commissions and spread costs.

Why "vertical"
Beginner
Both options share an expiry but differ in strike. On old option price boards strikes were listed vertically, hence the name.
Debit vs credit
Intermediate
A bull call spread needs a known payment up front for an unknown later return, while a bull put spread collects cash up front in exchange for a possible payout later.1
Short-term tools
Advanced
Because the payoff is capped and time-limited, verticals suit views about the near future rather than long-term forecasts.1 See Option Greeks.
Common mistakes
Strikes too far apart
More reward, but a lower chance of reaching it.
Ignoring assignment
The short leg can be assigned early. See Exercise and Assignment.
Holding into expiry near a strike
Pin risk can leave an unhedged position.
Forgetting costs
Two legs double the trading costs.
