How much cash would I need if all my cash-secured puts got assigned at once?

How this is calculated

• This assumes worst-case simultaneous assignment on every put you log. That's unlikely on any single ordinary day, but it isn't impossible during a broad, sharp market selloff where many short puts finish in the money at once.
• Capital required for each put equals its strike price times 100 shares times the number of contracts, added up across every position you log.
• This assumes standard equity option contracts covering 100 shares each. If any position uses an adjusted contract size, adjust your inputs to match before logging it.
• This tool doesn't account for puts you might roll or close before expiration. It only totals the cash needed if every logged position were assigned exactly as entered.
• This tracker only exists in your browser tab for this session and resets when you close or reload the page. Nothing is saved or sent anywhere.
