Tools — Put-Selling Yield Calculator

What does that put actually pay?

Enter a ticker to load its listed expirations. Pick the expiration and strike you’re interested in — the calculator runs against live market data and returns the annualized yield, your cost basis if assigned, and the cushion to breakeven from today’s spot.

What the numbers mean

Annualized yield
Premium ÷ strike, scaled to a full year. Tells you what the put pays at the rate you’d earn if you ran the same setup back-to-back for 12 months.
Cost basis if assigned
Strike minus the premium you collected. If you’re put the shares, this is what you’ll have paid per share — a lower number than the strike, often lower than today’s spot.
Downside to breakeven
How far the underlying can drop from today before assignment puts you underwater on the trade. The premium widens this cushion vs simply buying the stock at spot.
ATM implied vol
The current at-the-money implied volatility from the chain. Higher IV = richer premiums, usually because the market is pricing in more uncertainty.

This isn’t a recommendation. Value Options Letter doesn’t know your portfolio. Whether the yield this put pays is “good” depends on whether the underlying is a company you’d actually want to own at the assigned price. That’s the analyst work we do every week in the paid letter.
