Bull Call Spread vs Bull Put Spread: Which Fits Your Trade?
A bull call spread and a bull put spread both profit from the same bullish or neutral-to-bullish view: you expect a stock to rise or at least hold its ground. The difference is how each strategy gets paid. The bull call spread is a debit spread built entirely from calls, and the bull put spread is a credit spread built entirely from puts. Same directional bet, opposite cash flow at entry.
This guide compares both strategies side by side, walks through a worked example from each calculator’s own numbers, and links to the free tools so you can model your own strikes before placing a trade. Options trading involves risk, including the possible loss of the full amount invested.

What Is a Bull Call Spread?
A bull call spread buys a call at a lower strike and sells a call at a higher strike, both in the same expiration. Because the long call costs more than the premium collected from the short call, the trade pays a net debit up front. That debit is the maximum loss, and the trade reaches max profit if the stock closes at or above the higher strike at expiration. Use the bull call spread calculator to see the exact debit, breakeven, and max profit for your own strikes.
What Is a Bull Put Spread?
A bull put spread sells a put at a higher strike and buys a put at a lower strike, both in the same expiration. Because the short put is worth more than the long put, the trade collects a net credit up front. That credit is the maximum profit, realized in full if the stock closes at or above the higher strike at expiration. Use the bull put spread calculator to see the exact credit, breakeven, and max loss for your own strikes.
Bull Call Spread vs Bull Put Spread: Key Differences
| Factor | Bull Call Spread | Bull Put Spread |
|---|---|---|
| Legs | Buy lower-strike call, sell higher-strike call | Sell higher-strike put, buy lower-strike put |
| Cash flow at entry | Net debit paid | Net credit received |
| Max profit | Spread width minus the net debit paid | The net credit received |
| Max loss | The net debit paid | Spread width minus the net credit received |
| Full-profit scenario | Stock closes at or above the higher call strike | Stock closes at or above the higher put strike |
| Effect of time decay | Works against the trade until the stock moves in its favor | Works in the trade’s favor while the stock stays above the short strike |
| Assignment risk before expiration | On the short call if it goes in the money | On the short put if it goes in the money |
The core trade-off is cash flow versus time decay. A bull put spread gets paid today and keeps that credit as long as the stock stays above the short strike, so time decay works in its favor while the trade is winning. A bull call spread pays today and needs the stock to actually rise to earn a profit, so time decay works against it until the move happens. Both cap risk at the spread width, so neither strategy can lose more than the difference between the two strikes.
When to Use a Bull Call Spread
A bull call spread tends to fit when you expect a more meaningful move higher and want defined risk without paying for the higher premium of an outright long call at a similar strike. Selling the higher-strike call lowers the cost of the position, at the cost of capping the profit at the higher strike instead of letting it run. Compared with a long call, the bull call spread trades away unlimited profit potential for a lower net cost and a defined max loss.
When to Use a Bull Put Spread
A bull put spread tends to fit when you expect a stock to stay flat or drift higher rather than rally sharply, since the position profits even if the stock does not move at all. It also fits traders who would rather collect a credit and let time decay work for them than pay for a directional move to happen. Compared with a naked short put, the long put caps the otherwise large downside risk at the cost of a smaller credit.
A Quick Example with Real Numbers
Bull call spread: XYZ is trading at $50.00. Buy the $50 call and sell the $55 call, a $5.00-wide spread. Net debit paid is $2.00 per share ($200 per contract). Breakeven is $52.00 ($50.00 plus $2.00). Max profit is $300.00 (the $5.00 width minus the $2.00 debit, times 100) if the stock closes at or above $55 at expiration. Max loss is $200.00, the full debit paid, if the stock closes at or below $50.
Bull put spread: XYZ is trading at $50.00. Sell the $50 put and buy the $45 put, a $5.00-wide spread. Net credit received is $1.50 per share ($150 per contract). Breakeven is $48.50 ($50.00 minus $1.50). Max profit is $150.00 if the stock closes at or above $50 at expiration, keeping the full credit. Max loss is $350.00 (the $5.00 width minus the $1.50 credit, times 100) if the stock closes at or below $45.
Different starting prices and strikes, but the shape of the trade-off is consistent: the bull put spread risks more than it can make ($350 max loss versus $150 max profit) in exchange for getting paid up front and profiting even if the stock just holds steady. The bull call spread risks less than it can make ($200 max loss versus $300 max profit), but only pays off if the stock actually rises to the higher strike.
