Covered Call If-Called Total Return
Annualized total return on a covered call assuming the stock finishes above the strike and is called away. Includes both the premium received and the capital gain from the stock cost basis up to the strike, divided by the cost basis.
When to use: Use to evaluate the upside scenario on a covered call: what total annualized return you realize if your shares get called. Pair with the static return to see both sides of the assignment-vs-no-assignment outcome.

Real-Life Examples
Example 1: OTM CC with Capital Gain
On April 29, 2026 you sell a 45-day call (expiring June 13, 2026) at a $55 strike for $1.20 of premium. Your stock cost basis is $50.
Given
Step-by-Step
Premium plus capital gain combine to 12.4% over 45 days, annualized to ~100%. The figure is dominated by the $5 capital gain — not by the option premium.
Example 2: ITM CC at Loss to Basis
On April 29, 2026 you sell a 30-day call expiring May 29, 2026 at a $40 strike on stock with a $45 cost basis, collecting $0.80 of premium.
Given
Step-by-Step
Writing an ITM call below your basis locks in a loss if assigned. The premium is not enough to offset the capital loss — a useful warning when "harvesting time decay" on underwater positions.
Frequently Asked Questions
Because it represents the actual capital deployed — the price you paid for the shares. Some traders use the current stock price instead, which answers a different question ("what return am I earning on today's value?") rather than ("what return have I earned on the dollars I committed?").
They bracket the two relevant outcomes: stock stays below strike (static), stock finishes above strike (if-called). Together they tell you the range of annualized returns the trade can produce, ignoring intra-period mark-to-market.
Dividends paid during the holding period (which would add to total return), commissions and slippage, taxes on assignment, and the path-dependent reality that early assignment can occur before expiration.
