Maximum Profit
Maximum profit is the most a trade can make. Learn which strategies have unlimited upside, which cap out at a fixed number, and why knowing your ceiling matters.
Maximum profit is the most money a trade can make in the best-case scenario. Some strategies have an unlimited ceiling. Others cap out at a fixed number you can calculate before you ever enter.
Knowing your max profit is the other half of understanding a trade. Pair it with your max loss and you have the full shape of the bet in front of you. Let me walk through it.
Open Roof or Fixed Ceiling
Think of max profit as the roof over your trade. Some trades have no roof at all, the sky is the limit. Others have a firm ceiling you will bump into no matter how far the stock runs.
Open roof (unlimited). When you buy a call, there is no cap. If the stock keeps climbing, your profit keeps climbing with it. A rally to the moon pays you all the way up. Buying a put is nearly the same on the downside, capped only because a stock can fall no lower than zero.
Fixed ceiling (defined). The moment you sell an option as part of the trade, you usually cap your upside. Covered calls, credit spreads, and most income strategies trade away unlimited upside for a known, collected premium. You know the most you can make on day one.
Finding the Number
For the trades where profit is capped, the number is easy to pin down.
A covered call. Your max profit is the gain on the stock up to the strike, plus the premium you collected. Own shares at $200, sell a $210 call for $3, and the most you can make is $10 of stock gain plus $3 premium, which is $13 a share, or $1,300.
A credit spread. Your max profit is simply the credit you collected when you opened it. Sell a spread for a $2 credit, and $200 is the most you can make, achieved if the options expire worthless.
A bought call or put. There is no fixed number to calculate. The best case is limited only by how far the stock moves, which is why traders call it unlimited (or, for puts, capped only at zero).
Why the Ceiling Matters
Knowing max profit keeps your expectations honest. If a trade can make at most $200, you should not white-knuckle it hoping for $2,000. And it shapes your decisions: a capped-profit trade often has a high probability of success, while an unlimited-profit trade usually wins less often but pays much more when it does.
Neither is better. They are different tools. But you only know which one you are holding if you have checked the roof.
- Max profit is the most a trade can make in the best case.
- Buying a call has an unlimited ceiling; a put is capped only at zero.
- Selling premium usually gives a fixed, known max profit.
- Credit spread max profit is the credit collected; covered call is stock gain plus premium.
Pop Quiz
Three quick questions to see what stuck. Pick an answer and the explanation shows up right away.
Which trade has an unlimited maximum profit?
A bought call has no cap. As the stock keeps rising, your profit keeps rising with it.
You sell a credit spread for a $2 credit. What is your max profit?
On a credit spread, the credit you collect is the most you can make: $2 times 100 is $200.
Why does knowing max profit matter?
Knowing the ceiling stops you from over-hoping and helps you pick between high-probability capped trades and rarer big-payoff ones.
Bottom Line
Maximum profit is the roof over your trade. Bought calls leave it wide open, so profit rides the stock as far as it goes. Sold-premium strategies put a firm ceiling on it, known the day you enter.
Check the roof alongside the floor, and you see the whole trade at once: the best case, the worst case, and whether the shape fits what you are trying to do.
Keep going: pair this with your max loss, then weigh the two with the risk-reward ratio.
