Alastair,

I have used the CC calculator from time to time, and I agree with you about the ROI calculation. I recall we had some discussion about how one correctly calculates ROI for CCs on this thread a few months back. I posted an excel function that can give you a precise ROI, even for multiple writes over time on a stock you carry

For relatively small premiums (< 5%), the difference in calculated ROIs is not so great as to be of concern, but as your example points out when you get into the >20% range, it becomes significant. I just keep in mind that the calculator is giving the conservative result, and the ROI is typically better than what it says. If I need more precision, I do my own calculation.
