How to Calculate Annualized Yield on Options Trades

"I collected $150 in premium." That sentence is meaningless without context. Was it on $3,000 of capital or $30,000? Over 7 days or 45 days? Annualized yield is the metric that lets you compare any options trade against any other trade, any stock dividend, any savings account, on equal footing. If you are not calculating it on every trade, you are flying blind.

The Core Formula

Annualized yield converts any time-limited return into a yearly percentage so you can compare apples to apples. The formula is:

The three inputs are straightforward: how much premium you collected, how much capital you tied up, and for how long. Let us walk through each component.

Premium Collected

This is your net credit after commissions. If you sold a put for $1.50 and paid $0.65 in commissions, your net premium is $149.35 ($1.50 x 100 - $0.65). Always use the net number. Commissions are small per contract but compound over hundreds of trades per year.

Capital at Risk

This is where most people make their first mistake. For a cash-secured put, your capital at risk is the strike price times 100, minus the premium received. If you sell a $25 put for $0.75, your capital at risk is ($25 x 100) - $75 = $2,425. Some traders use just the strike times 100 ($2,500 in this case), which is also valid and more conservative.

For a covered call, your capital at risk is typically your cost basis in the shares minus the premium collected. If you bought shares at $24.25 (after being assigned on the put above) and sell a $26 call for $0.60, your capital basis is ($24.25 x 100) - $60 = $2,365.

Days to Expiration (DTE)

Use calendar days, not trading days. If you sell a put on Monday and it expires the following Friday, that is 11 days, not 9. The formula uses 365 because your capital is locked up on weekends and holidays too.

Worked Example: Cash-Secured Put

You sell 1 AMD $120 put, 30 DTE, for $3.20 in premium.

• Premium: $3.20 x 100 = $320
• Capital at risk: $120 x 100 - $320 = $11,680
• DTE: 30

That does not mean you will earn 33.3% this year. It means if you could replicate this exact trade every 30 days for a full year, your return would be approximately 33.3%. In practice, IV fluctuates, strikes shift, and some months you skip trades. But annualized yield gives you a consistent yardstick.

Worked Example: Covered Call

You own 100 shares of SOFI at a cost basis of $8.50 per share. You sell a $9.00 call, 14 DTE, for $0.25.

• Premium: $0.25 x 100 = $25
• Capital at risk: $8.50 x 100 = $850
• DTE: 14

This looks absurdly high, and that is the important lesson about annualized yield on short-dated trades. A 14-day trade gets multiplied by 26 (365/14). Even a small absolute return looks huge when annualized. This is mathematically correct but practically misleading. You will not replicate a 14-day trade 26 times in a row. Use annualized yield to compare trades of similar duration. Comparing a 7-DTE against a 45-DTE annualized number can distort your decision-making.

Worked Example: Full Wheel Cycle

This is where it gets interesting. A complete wheel cycle includes the put sale, potential assignment, and call sale until shares are called away. Here is a real-world example:

1. Sell $25 put, 30 DTE, for $0.80: Collect $80. Stock drops to $24.50, you get assigned.
2. Sell $25 call on shares, 21 DTE, for $0.55: Collect $55. Stock stays at $24.80, call expires worthless.
3. Sell $25 call again, 21 DTE, for $0.50: Collect $50. Stock rises to $25.30, shares are called away at $25.

Total premium collected: $80 + $55 + $50 = $185. Total time: 30 + 21 + 21 = 72 days. Capital at risk: $2,500 (put strike x 100). Stock profit: $25 - $24.50 (assignment price after premium) + $0.80 put premium = you exited even on shares, so your profit is purely from premium.

Common Mistakes

• Using margin buying power instead of notional value: If your broker only requires $6,000 margin for a $12,000 stock, your "return on buying power" looks 2x better. But your actual risk is the full notional value. Use full cash-secured amounts for honest yield calculations.
• Ignoring losing trades: Annualized yield on winners is easy. Real portfolio yield must include trades where you bought back at a loss or got assigned and took a drawdown. If 3 out of 12 monthly trades lost money, your real annualized yield is dramatically lower than the average of your winners.
• Comparing different DTEs raw: A 7-DTE trade annualizes to a mind-boggling number. Always compare within similar time frames, or better yet, look at your actual trailing 90-day return and annualize that.
• Forgetting to subtract commissions and fees: On a $50 premium collection, $1.30 in commissions is 2.6% of your income. On 50 trades per year, that adds up.

What Is a Good Annualized Yield?

For cash-secured puts on quality stocks at 25-35 delta, you should target 15-30% annualized on individual trades. For covered calls on assigned shares, 12-25% is solid. For full wheel cycles including the occasional bad trade, a realistic portfolio-level return is 12-20% annualized. Anyone consistently claiming 40%+ on their whole portfolio is either using margin, cherry-picking results, or taking on risk they have not accounted for.

These numbers assume you are selling on blue-chip and large-cap growth stocks. Higher IV stocks will show higher per-trade yields but also higher drawdowns when things go wrong.

Automate the Calculation

You do not need to run this formula by hand. Our options profit calculator computes annualized yield automatically for every trade you model. The CSP calculator and covered call calculator both display annualized yield alongside raw return, breakeven price, and probability of profit. Use them to compare trades before committing capital.
