Credit vs Debit Spreads

By Yojana Mandon · Updated June 2026 · 2 min read · Risk disclaimer

Vertical spreads come in two flavours. A debit spread costs money to open and profits from a directional move; a credit spread pays you upfront and profits from time decay and the stock staying put or moving your way. Choosing between them comes down to your view and to implied volatility.

Debit spreads

You pay a net debit — for example a bull call spread (buy a call, sell a higher call). Maximum loss is the debit paid; maximum profit is the distance between strikes minus the debit.

Debit spreads are best when options are relatively cheap (low IV) and you expect a clear directional move. They are a lower-cost, capped alternative to buying a single option.

Credit spreads

You collect a net credit — for example a bull put credit spread (sell a put, buy a lower put). Maximum profit is the credit; maximum loss is the strike width minus the credit.

Credit spreads work best when options are expensive (high IV) and you want time decay and a high probability of profit on your side, even if the stock only stays still.

How to choose

Match the structure to volatility: sell credit spreads when IV is high and rich; buy debit spreads when IV is low and cheap.

Match it to conviction, too: a strong directional view suits a debit spread, while a “this stock won’t break this level” view suits a credit spread.

Worked example. Stock at $100. A bull call debit spread buying the $100 call and selling the $105 call for a $2 debit risks $200 to make up to $300. A bull put credit spread selling the $95 put and buying the $90 put for a $1.20 credit collects $120 and risks $380 — higher probability, smaller reward.

Key takeaways

Debit spread: pay to open, profit from a directional move, low-IV friendly.
Credit spread: paid to open, profit from time decay, high-IV friendly.
Both cap max profit and max loss at the strike width.
Pick the structure that matches both volatility and conviction.

Frequently asked questions

Which has a higher probability of profit?

Credit spreads usually do, because they can profit even if the stock does nothing — but their reward-to-risk is typically worse than a debit spread.

Do credit spreads require more margin?

They require buying-power equal to the spread width minus the credit, set aside as the maximum possible loss.

Can I lose more than the spread width?

No. Both legs are defined, so your maximum loss is capped at the strike width minus the premium.
