Options Income Calculator for Cash-Secured Put Positions
Calculate the premium income, cash requirements, effective cost basis, and assignment scenarios for selling cash-secured puts. A cash-secured put involves selling a put option while holding enough cash to buy the shares if assigned. Investors use this strategy to generate income while waiting to buy a stock at a discount, or as part of the wheel strategy cycle with covered calls.
AAPL trades at $150. You sell a $145 put for $2.00/share expiring in 30 days. You set aside $14,500 in cash. You collect $200 in premium. If the stock stays above $145, you keep the cash and the premium for a 16.79% annualized return. If assigned, you buy 100 shares at an effective cost of $143.00/share.

Frequently Asked Questions
Understanding cash-secured puts and the wheel strategy
What is a cash-secured put?
A cash-secured put is an options strategy where you sell a put option while holding enough cash in your account to buy the shares if assigned. You collect the premium upfront as income. If the stock stays above the strike price, the option expires worthless and you keep the premium and your cash.
This strategy is used by investors who want to buy a stock at a discount. If assigned, your effective purchase price equals the strike minus the premium received.
How much cash do I need?
You need enough cash to buy 100 shares at the strike price for each contract you sell. For example, selling one put with a $145 strike requires $14,500 in cash. This is the "cash-secured" part — your broker will hold this amount as collateral.
The return calculation uses the cash committed (strike × shares) as the denominator, since that is the capital at risk in the position.
What happens if my put is assigned?
If the stock price is below the strike at expiration, the put buyer will exercise the option. You are obligated to buy the shares at the strike price. Your effective cost basis is the strike price minus the premium received.
Many traders view assignment as a positive outcome — they wanted to own the stock anyway and bought it at a discount. After assignment, you can sell covered calls against your new shares (the "wheel strategy").
What is the wheel strategy?
The wheel strategy is a continuous income cycle: sell a cash-secured put, get assigned (buy shares), sell covered calls, get assigned (sell shares), repeat. Each step generates premium income.
Use this calculator to evaluate the put side, and the Covered Call Calculator for the call side. Together they let you model the entire wheel before committing capital.
