How to use the options calculators
Option premium looks generous until you annualize it against the capital it ties up. These calculators express every trade as return on capital and an annualized rate so a 14-day cash-secured put can be compared honestly with a 45-day covered call, or with simply holding the shares.
The P/L calculator draws the payoff diagram for long calls, long puts, covered calls, and cash-secured puts, including breakeven and max-loss points. The wheel annualizer extends that to a repeating strategy so you can see what a fixed capital base plausibly produces over a year.
Every calculator on this page keeps your inputs in the URL, so you can bookmark a scenario or send it to someone else and they will see the exact same result.
