Covered Call and Cash-Secured Put Breakeven
Breakeven is the stock price where a trade stops making money and starts losing it. For the two legs of the Wheel, the formulas are short: a cash-secured put breaks even at the strike minus the premium, and a covered call breaks even at your share cost minus the premium. The useful part is what those formulas leave out: fees, time value before expiration, and how the number keeps moving as you sell one call after another on the same shares.
All prices and premiums below are hypothetical and rounded for easy math. They are not quotes, live prices, or typical results.
The formulas at a glance
| Position | Breakeven at expiration | Best case | Main risk |
|---|---|---|---|
| Cash-secured put | Strike − net premium per share | Keep the premium if the stock finishes above the strike | Assigned shares keep falling below the breakeven |
| Covered call | Share cost − net premium per share | (Strike − share cost) + premium if called away | The stock falls; the premium only cushions it |
| Whole Wheel position | Put strike − all net premiums collected on it | Called away above the running breakeven | Selling a call below the running breakeven and getting called away |
“Net premium per share” means the premium minus fees, divided by 100 shares per contract. A $0.65 fee is less than a penny per share, so it rarely changes the picture, but it is not zero.
Cash-secured put breakeven
When you sell a put, you agree to buy 100 shares at the strike if assigned. The premium you collected is already yours, so your effective purchase price is the strike minus that premium. That effective price is the breakeven. The mechanics of the put itself are on cash-secured puts explained.
XYZ trades at $48. You sell one $45 put for $1.20 and pay a $0.65 fee, so you keep $119.35, or about $1.19 per share.
Breakeven = $45.00 − $1.19 = about $43.81.
At expiration: if XYZ is at $47, the put expires and your result is +$119.35. If XYZ is at $43.81, you are assigned at $45 on shares worth $43.81, a $119 paper loss that the premium cancels, so you are about even. If XYZ is at $40, you are assigned and hold shares about $381 below your effective cost ($43.81 − $40 = $3.81 × 100), before any assignment fee.
Below the breakeven, every $1 the stock falls is another $100 lost per contract. The premium is a fixed cushion, not a floor. That is the main point of the Wheel strategy risks guide.
Covered call breakeven
When you own 100 shares and sell a call against them, the premium lowers what the shares effectively cost you, and the strike caps what you can earn while the call is open. The basics are on covered calls explained.
You own 100 shares of XYZ bought at $50. You sell one $55 call for $1.00 and pay a $0.65 fee, keeping $99.35.
Breakeven = $50.00 − $0.99 = about $49.01.
Maximum result if called away at $55 = ($55 − $50) × 100 + $99.35 = $599.35.
At expiration: at $45 the call expires and you are down about $400.65 instead of $500 without the call. At $60 you are called away at $55 and keep $599.35, while simply holding the shares would have been up $1,000. The call cushioned the drop by $99.35 and gave up $400.65 of the rally.
The running breakeven across a Wheel cycle
In the Wheel, the put and the calls that follow are one position on the same shares. The breakeven that matters is the put strike minus every net premium you have collected on that position so far. Each call you sell lowers it a bit more. The free Wheel cost basis calculator keeps this running number for you.
| Step | Trade | Premium per share | Running breakeven |
|---|---|---|---|
| 1 | Sell $45 put, assigned | $1.20 | $45.00 − $1.20 = $43.80 |
| 2 | Sell $46 call, expires | $0.90 | $43.80 − $0.90 = $42.90 |
| 3 | Sell $46 call, called away | $0.70 | $42.90 − $0.70 = $42.20 |
The running breakeven also tells you where a covered call strike would lock in a loss. Suppose at step 3 you had sold a $42 call for $0.50 instead. Your breakeven would drop to $42.40, and being called away at $42 would leave the cycle at ($42.00 − $42.40) × 100 = −$40 before fees. Whether that is ever worth it is the subject of selling covered calls below cost basis.
Why breakeven is an expiration number
All of the formulas above describe the result if you hold the option to expiration. Before then, the option still carries time value, and its price moves with the stock and with implied volatility. If you buy to close a short put early, your result is the premium you collected minus what you pay to close, not the distance from the breakeven. A stock sitting just above your put breakeven with two weeks left can still show a loss on the option, because the put is still priced for the chance of a further drop.
So use breakeven to answer “where does this trade stop working if it runs its course?” and use the current price of the option to answer “what happens if I close now?” The guide to when to close a covered call or put covers the second question.
Common breakeven mistakes
- Using the strike as the breakeven. On a short put, the strike is where assignment starts, not where the loss starts. The loss starts at the strike minus the premium.
- Forgetting the shares’ real cost. A covered call’s breakeven uses what you actually paid for the shares (or your Wheel running breakeven), not today’s price.
- Counting premium twice. If you already subtracted the put premium to get your share basis, do not subtract it again when you add up call premiums.
- Treating breakeven as a stop. Nothing happens automatically at the breakeven. It is a reference price, and the stock can trade through it.
- Mixing tax basis and strategy basis. Your broker’s cost-basis column is for tax lots and may be calculated differently. Keep your own running number for decisions, and see Wheel strategy taxes for the reporting side.
Breakeven is not the same as a good trade
A lower breakeven sounds safer, but you buy it by taking more premium, which usually means a closer strike, a riskier stock, or a higher-volatility moment. Compare trades as a return on the capital they tie up with how to compare Wheel premiums, and only sell puts on shares you would be content to own, as covered in stock selection for the Wheel. The free Wheel calculator shows the breakeven, return on capital, and annualized comparison for a single put or call side by side.

FAQ
What is the breakeven on a cash-secured put?
At expiration, the breakeven is the strike minus the premium you received per share, after fees. A $45 put sold for $1.20 breaks even near $43.80. If the stock finishes above that price you have a profit; below it, you have a loss that grows by $100 for every $1 the stock falls, per contract.
What is the breakeven on a covered call?
At expiration, it is the price you paid for the shares minus the call premium per share, after fees. Shares bought at $50 with a $1.00 call sold against them break even near $49.00. The call lowers the breakeven by the premium, but it also caps your gain at the strike.
Does selling a covered call lower my breakeven?
Yes, by the net premium you collect, and each new call lowers it again. That is useful, but it is a fixed amount. If the stock falls far below your breakeven, the premium does not grow to cover the loss, and you have also capped your upside while the call is open.
How do commissions and fees change the breakeven?
Divide the total fee by 100 shares and subtract it from the premium per share. A $0.65 contract fee on a $1.20 put leaves $1.1935 net per share, so the breakeven moves from $43.80 to about $43.81. Some brokers also charge assignment or exercise fees; add those if yours does.
Is the breakeven the same before expiration?
No. The breakeven formulas are expiration values. Before expiration the option still has time value, so closing early can show a loss even when the stock is above the put breakeven, or a gain when it is below. The price to buy to close the option decides your result if you exit early.
What is my breakeven after several covered calls in the Wheel?
Start with the put strike you were assigned at and subtract every net premium you have collected on that position, put and calls. Assigned at $45 after a $1.20 put, then two calls for $0.90 and $0.70, your running breakeven is about $42.20 before fees.
Why does my broker show a different cost basis than my breakeven?
Broker cost basis is a tax-lot number, and brokers often handle assigned-put premium and covered-call premium differently from the running strategy math on this page. Both can be correct for their purpose. Use your broker and a tax professional for tax reporting, and your own running breakeven for trade decisions.
