Buy a call and sell a higher-strike call, same expiry. The short call finances part of the long one: lower cost and lower breakeven than a bare call, in exchange for a capped maximum profit at the upper strike.

Market inputs

Premiums start as Black-Scholes model values — overwrite them with your broker’s real quotes for exact numbers.

Common questions

What is the max profit on a bull call spread?
(Width between strikes − net debit) × 100. Reached at or above the short strike at expiry.
What is the max loss?
The net debit paid. Below the long strike at expiry both calls expire worthless.
Why use a spread instead of a call?
Selling the upper call reduces cost and time-decay drag; the trade-off is giving up gains beyond the short strike.

Educational model, not trade advice. Options involve substantial risk and are not suitable for every investor — read the OCC’s Characteristics and Risks of Standardized Options. Model values use Black-Scholes with your inputs (constant volatility, European exercise, no dividends) and will differ from live market prices.

Research and education only — not financial advice. TENKis not a registered investment adviser or broker-dealer and gives no personalized advice. Every call is impersonal — identical for all users, generated on a schedule from SEC filings plus a delayed/third-party price feed — may be wrong or out of date, and is not a recommendation to buy or sell any security. The operator and an affiliated trading operation may hold or trade the securities TENK rates; see Disclosures. Past performance does not guarantee future results. Do your own research.
