Bull call spread calculator
Model a bull call spread — a bullish, defined-risk debit strategy — and see the payoff diagram, breakeven, max profit, and max loss before you place the trade. Adjust the strikes and expiration and watch the numbers update live.
How a bull call spread works
You buy a lower-strike call and sell a higher-strike call with the same expiration. Selling the higher call offsets part of the cost, so the spread is cheaper than buying the call outright — in exchange, your profit is capped at the higher strike.
Max loss
The net debit you pay to open the spread.
Max profit
Strike width − net debit.
Breakeven
Lower strike + net debit.
Common questions
What is a bull call spread?
A bull call spread is a bullish, defined-risk debit strategy: you buy a lower-strike call and sell a higher-strike call with the same expiration. It costs a net debit and caps both your maximum profit and maximum loss.
How do I calculate max profit, max loss, and breakeven?
Max loss = the net debit you pay. Max profit = the difference between the strikes minus the net debit. Breakeven = the lower strike plus the net debit (per share).
Is the calculator free?
Yes. You can build the spread and read its payoff for free; an account is only needed to save it.
