Bull Call Spread Strategy - Definition, Example & Calculator
Imagine you’re fairly confident a stock will rise soon – but not too much. You want to profit from the move without risking too much capital. That’s exactly where the Bull Call Spread Strategy shines.
The bull call spread option strategy is one of the simplest yet most effective ways to express a moderately bullish view on a stock or index while keeping both risk and reward limited. It’s like driving with cruise control – you know your top speed (maximum profit) and your limit (maximum loss).
In this detailed guide, you’ll learn everything about the bull call spread strategy – its definition, how it works, examples, when to use it, and even how to calculate profits using a bull call spread calculator. We’ll also compare bull call spread vs bull put spread to help you pick the right strategy for your goals.
What is a Bull Call Spread Strategy?
The bull call spread strategy is a two-leg options trading structure adopted whenever you anticipate a medium increase in the price of the underlying asset.
You do purchase one call at a lower strike price (to benefit on an increase) and you do sell another call at a higher strike price (to save on the price). Both options share the same expiry date and underlying asset.
In essence, it’s a vertical spread designed to:
- Limit your losses if the stock doesn’t move up.
- Cap your profits if it moves up beyond a point.
How Does a Bull Call Spread Work?
Here’s how the bull call spread option strategy functions step by step:
- Buy a Call Option at a Lower Strike: This gives you the right (but not the obligation) to buy the asset at this price before expiry.
- Sell a Call Option at a Higher Strike: This limits your potential profit but helps offset part of the premium paid for the first call.
- The difference between the two strike prices defines your profit ceiling.
When the asset’s price rises:
- The long call gains value.
- The short call limits profit beyond a point.
- If the asset falls or remains flat, your maximum loss is limited to the net premium paid.
Key Components of the Bull Call Spread Option Strategy
Component | Description |
Long Call Option | Bought at a lower strike price – the main profit driver. |
Short Call Option | Sold at a higher strike price – reduces cost and caps profit. |
Net Premium Paid | Premium paid for the long call minus premium received from the short call. |
Maximum Profit | Difference between strike prices minus net premium paid. |
Maximum Loss | Limited to the net premium paid. |
Break-Even Point | Lower strike price + net premium paid. |
Example of a Bull Call Spread
Let’s take a simple example to understand this strategy better:
- Stock: ABC Ltd.
- Current Price: ₹100
- Buy 1 Call Option (Strike 100) at ₹5
- Sell 1 Call Option (Strike 110) at ₹2
Net Premium Paid = ₹5 – ₹2 = ₹3
Now, let’s analyze potential outcomes:
Stock Price at Expiry | Profit/Loss |
Below ₹100 | -₹3 (maximum loss) |
₹105 | ₹2 (partial profit) |
₹110 or above | ₹7 (maximum profit) |
Maximum Profit = ₹10 (strike difference) – ₹3 (premium) = ₹7 per share. Maximum Loss = ₹3 per share (net premium paid).
This example shows that even if ABC Ltd. rises strongly, your profit is capped at ₹7 – but your risk is also strictly limited.
Step-by-Step Setup of a Bull Call Spread
- Detect a Moderately Bullish Trend: Check the trend using any of the following indicators such as RSI, MACD, or moving averages.
- Best Strike Prices: Purchase a call option that is slightly in-the-money (ITM) or at-the-money (ATM). Sell a call option of a low out-of-the-money (OTM).
- Option Expiry Date: Select an option expiry date that reflects your short-term confidence which is normally 2-4 weeks.
- Execute the Trade: Buy a lower strike call. Sell higher strike call.
- Monitor and Adjust: Track market movement. If your target is achieved early, consider closing both positions.
Bull Call Spread Profit and Loss Calculation
Maximum Profit Formula:
Max Profit=(Higher Strike-Lower Strike)-Net Premium Paid\text{Max Profit} = (\text{Higher Strike} – \text{Lower Strike}) – \text{Net Premium Paid}Max Profit=(Higher Strike-Lower Strike)-Net Premium Paid.
Maximum Loss Formula:
Max Loss=Net Premium Paid\text{Max Loss} = \text{Net Premium Paid}Max Loss=Net Premium Paid.
Break-Even Point:
Break-Even=Lower Strike+Net Premium Paid\text{Break-Even} = \text{Lower Strike} + \text{Net Premium Paid}Break-Even=Lower Strike+Net Premium Paid.
Let’s revisit our ABC Ltd. example:
- Lower strike = ₹100
- Higher strike = ₹110
- Net premium = ₹3
Then, Break-even = 100 + 3 = ₹103
So, the stock must rise above ₹103 for the strategy to start generating profit.

When to Use a Bull Call Spread Strategy
Use this strategy when you’re moderately bullish on the stock or index. It works best when:
- You expect a limited upside movement.
- Volatility is stable or slightly declining.
- You want to reduce premium cost versus buying a single call.
Example scenario: If you think Nifty (trading at 22,000) will rise to 22,300 in a month, a bull call spread helps you profit within that range with minimal risk.
Advantages of the Bull Call Spread
- Limited Risk: Your loss cannot exceed the net premium paid.
- Cost Efficiency: Selling one call helps finance the other, reducing cost.
- Defined Profit Range: You know your profit potential before entering.
- Beginner-Friendly: Easier to understand and manage than multi-leg options.
- Good for Sideways-to-Bullish Markets: Performs well in mild uptrends.
Disadvantages of the Bull Call Spread
- Capped Profits: You can’t benefit beyond the higher strike price.
- Time Decay Impact: Both options lose value as expiry approaches.
- Requires Correct Forecast: If the price remains flat or falls, you lose the premium.
- Not Suitable for Strong Bullish Trends: For sharp rallies, buying a single call may be better.
Bull Call Spread vs Bull Put Spread
Aspect | Bull Call Spread | Bull Put Spread |
Market View | Moderately bullish | Moderately bullish |
Setup Type | Debit spread (cost involved) | Credit spread (income generated) |
Execution | Buy low strike call, sell high strike call | Sell high strike put, buy low strike put |
Max Profit | Difference in strikes – net premium paid | Net premium received |
Max Loss | Net premium paid | Difference in strikes – net premium received |
Margin Requirement | Lower | Higher |
Risk Profile | Limited | Limited |
Trader Type | Conservative buyers | Premium sellers |
Note: If you prefer low risk and lower margin use, go for the bull call spread strategy. If you prefer earning premium income, choose the bull put spread.
Adjustments and Exit Strategies
Sometimes, market conditions change mid-way. Here’s how to handle it:
- If Stock Moves Up Quickly: Exit early and book partial profit before time decay erodes value.
- If Stock Moves Sideways: Roll over the position to the next expiry.
- If Stock Drops: Accept limited loss or close early to minimize time decay.
Strategies to Maximize Returns
- Choose highly liquid stocks or indices for tight bid-ask spreads.
- Avoid entering when implied volatility (IV) is extremely high.
- Select strike prices 5-10% apart for a balanced risk-reward.
- Don’t hold till expiry if profit hits 70-80% of target early.
- Use technical indicators like RSI (above 50) to confirm bullishness.
Common Mistakes to Avoid
- Ignoring Premium Costs: Don’t choose strikes that are too far apart – it increases cost.
- Overestimating Price Moves: Remember, it’s a moderate bullish strategy.
- Holding Expired Options: Time decay can eat into profits fast.
- Skipping Exit Strategy: Always plan your profit and stop-loss levels.
Real-Life Example of Bull Call Spread
- Underlying Asset: Nifty 50
- Current Price: ₹22,000
- Buy 22,000 CE @ ₹100
- Sell 22,300 CE @ ₹60
- Net Premium Paid = ₹40
Possible Outcomes:
Nifty at Expiry | Profit/Loss |
Below ₹22,000 | -₹40 (maximum loss) |
₹22,100 | -₹10 |
₹22,200 | +₹60 |
₹22,300 or above | +₹260 (maximum profit) |
Thus, the bull call spread gave a controlled exposure – with a risk of ₹40 and potential profit of ₹260.
This shows how the strategy provides clear visibility on your returns while minimizing risk exposure.
