How to Calculate Your True Break-Even Price After Options Assignment (Not What Your Broker Shows)

< p > Your AMD shares just landed in your account at an assignment price of $155.The stock is trading at $149.Your broker shows a $600 unrealized loss.You're tempted to panic-sell before it drops further.

< p > Stop.Before you do anything, calculate your < strong > actual break-even price < /strong> — because it's almost certainly not $155.

What Is Your True Break - Even After Assignment ?

< p > Your real break-even after a CSP assignment is not the strike price your shares were assigned at.It's the strike price minus every dollar of premium you collected from selling puts before assignment, net of fees:

< blockquote > Break - Even = Assignment Strike − (Total Net CSP Premiums ÷ Shares Assigned)

Full AMD Example Walkthrough

< p > Over the four weeks leading up to assignment, you sold three CSPs on AMD:

< table > Week < /th>Strike Net Premium < /th> < tbody > Week 1 < /td>$160 $229 < /td> Week 2 < /td>$158 $209 < /td> Week 3 < /td>$155 $179 < /td> Week 4 < /td>$155 → Assigned $249 < /td> < p > Total net premiums: $866.Break - even: $155 − ($866 ÷ 100) = $146.34 per share.< /strong>

The stock trading at $149 is not a $600 loss.It's a $264 unrealized gain relative to your real break-even. That's not just psychologically different — it completely changes what you should do next.

< h2 > Does Your Break - Even Keep Dropping After Assignment ? < p > Yes — and this is one of the most powerful aspects of the wheel strategy.Every covered call premium you collect after assignment pushes your break-even lower:

< ul >

Sell a $160 CC for $1.80 net → break-even drops to $144.54

< li > Sell a $158 CC for $1.50 net → break-even drops to $143.04 < li > Collect a $0.25 / share dividend → break-even drops to $142.79 < p > This is the mechanical elegance of the wheel.Given enough time and patience, your break-even can fall far below the stock's current price, effectively eliminating your assignment risk entirely.

< h2 > Why Does This Change Your Decision - Making ? < p > When AMD drops to $148 after assignment at $155, a trader looking at broker cost basis sees a $700 loss and might close the position or panic.A trader looking at their real ACB of $146.34 sees a position that's still technically profitable — and calmly sells another covered call to keep lowering the break-even further.

< p > The math doesn't just matter for your P&L. It matters for your emotional discipline during drawdowns. OptionWheelTracker shows your true break-even in real time, so you never have to calculate it manually again.
