Bear Call Spread Calculator
A bear call spread is a vertical credit spread: you sell a lower-strike call and buy a higher-strike call. You collect a net credit and profit if the stock stays below the short strike.

Practical example
When to use it
- Your bet is 'the stock will NOT be above my short strike at expiration' — weaker claim than 'the stock will fall'
- Implied volatility is elevated (high IV rank) — bear call spreads are short vega and monetize IV contraction
- You want positive theta and a high probability of profit, accepting that max loss > max profit
- You want defined risk compared to a naked short call (no unlimited upside exposure)
- Call skew is relatively flat/low (unlike puts) — the spread economics aren't dragged down by steep skew
Risks
- Max loss (width − credit) exceeds max profit (credit) — one uncontrolled loser can wipe out several winners
- Losses accelerate on a rally: short calls gain vega and delta quickly as spot approaches the short strike
- Early assignment possible if the short call goes ITM, especially around ex-dividend dates
- IV expansion after a bullish surprise can hurt even if price eventually retraces
The deeper breakdown
How a Bear Call Spread Works
Sell a call at strike A and buy a call at strike B (B > A), same expiration. You collect a net credit. If the stock is at or below strike A at expiration, both calls expire worthless and you keep the credit. Losses accumulate above the short strike, capped by the long wing at strike B.
Example
AAPL at $195. Sell the $195 call for $5.40, buy the $200 call for $3.00. Net credit: $2.40 ($240). Max loss = ($5 − $2.40) × 100 = $260.
The Real Bet
A bear call spread is the mirror of a bull put spread. The claim is "price will stay below this level" — weaker than a directional bearish thesis. It profits in flat, mildly down, and even mildly up tape as long as price stays below the short strike.

Why It's Often Worse Than a Bull Put
Because of put skew, at equivalent deltas the *put side* usually offers better credit-to-risk than the call side. Pros often prefer to sell premium via bull puts or iron condors and use bear calls only when they have a specific bearish bias and elevated call IV to harvest.
Key Takeaway
Bear call spreads harvest theta and short vega in elevated-IV, range-bound-to-falling tape. Structurally less attractive than bull puts due to skew, but useful when you want a defined-risk bearish expression.
