How much cash do I need for a cash-secured put?

Cash required = strike price × 100 × number of contracts. For one $45 put, you need $4,500. Your broker reserves this amount; if assigned, you buy the shares at the strike.

Can I use margin for cash-secured puts?

Cash-secured means no margin—you must have the full amount in cash. Using margin changes the strategy (naked or margin-backed put) and has different capital requirements.
