A vertical spread where you pay net premium (buy the more expensive option, sell the cheaper one). Defined risk and defined reward. The opposite of a credit spread.
⚡ KEY TAKEAWAY: You pay to play, with a known maximum loss. Debit spreads are directional bets with capped risk — the lower-cost alternative to buying options outright.
Why It Matters
Debit spreads are the defined-risk alternative to buying options outright. Instead of paying full premium for a directional bet, you offset part of the cost by selling a further-OTM option. Lower cost, lower max profit, but capital-efficient and risk-capped.
How It Works
Buy a closer-to-ATM option, sell a further-OTM option at the same expiration. Net cost = debit paid. Max profit = spread width − debit. Max loss = debit. The long leg gives you directional exposure; the short leg reduces cost but caps your upside.
Example
SPY at $580. Buy the $580 call for $8.50, sell the $590 call for $4.50. Net debit: $4.00. Max profit: $10 − $4 = $6.00 (if SPY above $590). Max loss: $4.00 (if SPY below $580). Breakeven: $584. Compared to buying the $580 call alone ($8.50 risk), the spread cuts your max loss in half.
Common Mistakes
Going too wide on the spread thinking you'll capture more upside. Wider spreads cost more and have lower ROC. Also: holding debit spreads to expiration for max profit. The last 10% of max profit has terrible risk/reward — close at 50-75% of max profit.
