SPY Cash-Secured Put Calculator

SPDR S&P 500 ETF

Selling a cash-secured put on SPDR S&P 500 ETF (SPY) means getting paid premium to set the price you'd buy the stock — while you wait. Set aside the strike × 100 per contract as collateral, and if SPY stays above your strike the put expires worthless and you keep the premium.

Implied volatility typically runs in the 12–22% range, so premiums are thinner than single names — but the liquidity and zero single-stock risk make it the default index-level covered call.

SPY cash-secured put FAQ

Is SPY a good stock for cash-secured puts?

Implied volatility typically runs in the 12–22% range, so premiums are thinner than single names — but the liquidity and zero single-stock risk make it the default index-level covered call. A cash-secured put on SPY only makes sense if you'd genuinely be happy owning the stock at your strike, since assignment means buying 100 shares per contract. Size the trade to the collateral you can comfortably reserve and avoid selling through earnings unless you understand the IV-crush trade.

How much cash do I need to sell a SPY put?

Your collateral is the strike price × 100 per contract. The calculator above pulls the live SPY put chain and shows the exact "Cash secured" figure for any strike and contract count, so you can match the trade to the capital you want to reserve.

What's the typical SPY cash-secured put yield?

Implied volatility typically runs in the 12–22% range, so premiums are thinner than single names — but the liquidity and zero single-stock risk make it the default index-level covered call.
