Selling Puts for Income — The Cash-Secured Put Strategy Explained
Last updated: April 20266 min readCalculator Tools
Most people buy options and lose money to time decay. Selling puts flips the script — you collect premium and time decay works in your favor. The catch: you need to be willing to buy the stock if it drops. Done right, selling puts generates consistent income while positioning you to buy stocks at a discount.
How Cash-Secured Puts Work
- Pick a stock you want to own at a lower price (e.g., AAPL at $175, you would buy at $165)
- Sell a put option at your target price ($165 strike, 30 days out, $2.50 premium)
- Collect premium immediately: $250 (2.50 x 100 shares)
- Hold $16,500 in cash (100 shares x $165 strike, in case you are assigned)
- Wait for expiration
The Two Outcomes
| Outcome | Stock at Expiry | What Happens | Your Result |
|---|
| Stock stays above $165 | $170+ | Put expires worthless | Keep $250 premium. Sell another put next month |
| Stock drops below $165 | $160 | You buy 100 shares at $165 | Own shares at $162.50 effective cost ($165 - $2.50 premium). You wanted to buy here anyway |
In both outcomes, you win. Either you keep the premium (income) or you buy a stock you wanted at a price below what others paid.
Monthly Put Selling Income
| Stock Price | Strike (5% OTM) | Monthly Premium (~2%) | Cash Required | Annual Income | Yield |
|---|
| $50 | $47.50 | $95 | $4,750 | $1,140 | 24% |
| $100 | $95 | $190 | $9,500 | $2,280 | 24% |
| $150 | $142.50 | $285 | $14,250 | $3,420 | 24% |
| $200 | $190 | $380 | $19,000 | $4,560 | 24% |
| $500 | $475 | $950 | $47,500 | $11,400 | 24% |
These are estimates at 2% monthly premium for 5% out-of-the-money strikes. Actual premiums depend on the specific stock's volatility and market conditions.
The Rules for Put Selling
- Only sell puts on stocks you want to own. If you would not buy the stock at the strike price without the option, do not sell the put. You must be comfortable being assigned
- Keep it cash-secured. Always have the cash to buy 100 shares. Selling puts on margin amplifies risk and can lead to margin calls
- Sell 3-5% out-of-the-money. This gives the stock room to fluctuate without triggering assignment while still collecting meaningful premium
- 30-45 days to expiration. This sweet spot balances decent premium with rapid time decay
- Close at 50-70% profit. If you collected $250 and the option is now worth $75, buy it back for a $175 profit. Free up your cash to sell another put
Risks to Understand
- Large drawdown: A stock can drop 20-50%. Your put premium cushion is 2-3%. You will own shares at a significant loss if the stock crashes
- Opportunity cost: Your cash is locked up securing the put. If a better opportunity comes along, your capital is committed
- Assignment timing: While rare before expiration, you can be assigned early — especially around dividend dates for deep in-the-money puts
The Wheel Strategy
Combine selling puts with covered calls for continuous income:
- Sell cash-secured puts → collect premium → wait
- If assigned (you buy shares): Sell covered calls on those shares → collect more premium
- If shares get called away: Go back to step 1 and sell puts again
- Repeat indefinitely: Collecting premium at every step
