The Short Answer: What Counts as a Good Premium Percentage?

A covered call premium of 1% to 4% of the stock's current price per month is generally considered a solid target for most retail traders. Annualized, that works out to roughly 12% to 48% in extra income on top of any dividends the stock already pays. The exact number that is right for you depends on how much upside you are willing to give up, how volatile the stock is, and how far out-of-the-money you want to sell.

Think of the premium percentage as your yield on the shares you already own. If you hold 100 shares of a $150 stock and collect $200 in option premium, that is a 1.33% yield for that contract period. Simple math, powerful compounding.

How Premium Percentage Is Calculated

The formula is straightforward:

Premium Percentage = (Option Premium Received ÷ Current Stock Price) × 100

Each standard options contract covers 100 shares. So if you sell one call and collect $1.85 per share, you received $185 in total premium. Divide $1.85 by the stock price to get the percentage.

You can also annualize it. If the contract expires in 30 days, multiply the monthly percentage by 12. If it expires in 45 days, divide by 45 and multiply by 365. Annualizing lets you compare covered calls with different expiration dates on an apples-to-apples basis, the same way you would compare savings account APYs.

Worked Example: Selling a Covered Call on AAPL

Let's say Apple (AAPL) is trading at $213.00. You own 100 shares. You look at the option chain and find a call expiring in 30 days with a $220 strike price — about 3.3% out-of-the-money — quoted at $2.10 per share.

Premium collected: $2.10 × 100 = $210 Premium percentage: $2.10 ÷ $213.00 = 0.99% for 30 days Annualized yield: 0.99% × 12 = approximately 11.8% per year

If AAPL stays below $220 at expiration, the option expires worthless, you keep the $210, and you still own your shares. If AAPL closes above $220, your shares get called away at $220. You still keep the $210 premium plus the gain from $213 to $220 — a total return of about 4.2% in 30 days — but you miss any rally above $220.

Now compare that to a more aggressive strike. The $215 call (about 0.9% out-of-the-money) might be quoted at $3.50, giving you a 1.64% monthly yield. More income, but your shares get called away much sooner if AAPL moves even slightly higher. The tradeoff is always the same: higher premium means less room for the stock to run.

What Drives the Premium Percentage Higher or Lower?

Three factors do most of the work:

1. Implied Volatility (IV): The market's expectation of how much the stock will move. Higher IV means fatter premiums. The CBOE publishes the VIX, which tracks implied volatility on the S&P 500. When VIX is elevated — say, above 20 — premiums across the board are richer. Individual stocks have their own IV, visible on any brokerage option chain.

2. Strike Distance: The further out-of-the-money your strike, the lower the premium. A call that is 10% above the current price will pay far less than one that is 1% above it. Most income-focused traders target strikes that are 3% to 8% out-of-the-money as a balance between yield and keeping the shares.

3. Days to Expiration (DTE): Options lose time value as expiration approaches — this is called theta decay. The Options Industry Council (OIC) notes that theta accelerates in the final 30 days of an option's life. Many traders sell 30-to-45-day contracts to capture the steepest part of that decay curve.

A high-volatility stock like NVDA might offer 3% to 6% monthly premiums even on strikes that are 5% out-of-the-money. A low-volatility stock like SPY might offer only 0.5% to 1.5% on similar strikes. Neither is wrong — they just reflect different risk profiles.

Risks You Need to Understand Before Chasing High Premiums

High premium percentages are not free money. Here is what you are actually trading away:

Capped upside: Once you sell the call, your profit on the stock is capped at the strike price. If AAPL jumps from $213 to $240 and your strike was $220, you miss $20 per share in gains. The $2.10 premium does not come close to covering that.

You still carry full downside: Selling a covered call does not protect you if the stock drops. If AAPL falls to $180, you lose $33 per share on the stock. The $2.10 premium offsets only about 6 cents on the dollar of that loss. FINRA reminds investors that covered calls reduce cost basis slightly but do not hedge against large declines.

Early assignment risk: American-style options — which is what most US stock options are — can be exercised by the buyer at any time before expiration. The OIC explains that early assignment is most likely when a call is deep in-the-money or just before an ex-dividend date. If your shares get called away early, you may miss a dividend payment.

Tax treatment: In the US, the IRS treats covered call premiums as short-term capital gains in most cases, regardless of how long you have held the stock. Selling a call can also affect the holding period of your shares under IRS qualified covered call rules. In Canada, the CRA generally treats option premiums as capital gains or income depending on your trading frequency and intent. Consult a tax professional before you start — this is not an area to guess on.

Realistic Monthly Yield Benchmarks by Stock Type

Here is a rough guide based on typical market conditions. These are not guarantees — premiums change daily with IV and market conditions.

Low-volatility blue chips (SPY, MSFT, JNJ): 0.5% to 1.5% per month on strikes 3% to 5% OTM. Annualized: 6% to 18%.

Mid-volatility tech and growth (AAPL, GOOGL, AMZN): 1% to 2.5% per month on strikes 3% to 6% OTM. Annualized: 12% to 30%.

High-volatility names (NVDA, TSLA, AMD): 2% to 6% per month on strikes 5% to 10% OTM. Annualized: 24% to 72%.

Those high-volatility numbers look exciting, but remember: the market is pricing in big moves for a reason. A 5% monthly premium on NVDA reflects the real possibility that NVDA moves 10% or more in either direction. If it drops 15%, your 5% premium looks small.

A practical starting target for most new covered-call traders is 1% to 2% per month on a strike that is at least 3% to 5% out-of-the-money. That range tends to offer meaningful income without giving up too much upside or taking on excessive assignment risk.

How to Find the Right Strike for Your Target Yield

Start with your yield target, then work backward through the option chain.

Step 1: Decide your minimum acceptable monthly premium percentage. Say you want at least 1%.

Step 2: Multiply the stock price by 1% to get your minimum dollar premium. For a $213 AAPL position, that is $2.13 per share.

Step 3: Scan the option chain for the furthest out-of-the-money strike that still pays at least $2.13. That strike gives you the most upside room while still hitting your income target.

Step 4: Check the delta of that option. Delta tells you the approximate probability that the option expires in-the-money. The OIC describes delta as ranging from 0 to 1 for calls. A delta of 0.20 means roughly a 20% chance of assignment. Most income traders prefer deltas between 0.15 and 0.35 — enough premium to matter, low enough assignment risk to be comfortable.

Step 5: Repeat this process every month or every 30 to 45 days as contracts expire. Consistency is what turns covered calls from a one-time trade into a reliable income stream.

What is a good monthly premium percentage for a covered call?

Most experienced covered-call traders target 1% to 4% of the stock price per month, depending on the stock's volatility and how far out-of-the-money the strike is. Lower-volatility stocks like SPY typically land in the 0.5% to 1.5% range, while higher-volatility names like NVDA can offer 3% or more. Your personal target should balance income with how much upside you are willing to cap.

Is a 2% monthly covered call return realistic?

Yes, 2% per month is achievable on moderately volatile stocks, especially when implied volatility is elevated. On a stock like AAPL trading around $213, a 30-day call with a strike 2% to 4% out-of-the-money can realistically pay $3 to $5 per share in active markets. The key risk is that higher premiums come with higher assignment probability and more capped upside.

How do I calculate the annualized return on a covered call?

Divide the premium per share by the stock price to get the period yield, then multiply by the number of contract periods in a year. For a 30-day contract, multiply by 12; for a 45-day contract, divide by 45 and multiply by 365. This gives you an annualized yield you can compare to other income investments.

Does selling a covered call affect my taxes?

In the US, the IRS generally treats covered call premiums as short-term capital gains, and selling a call can affect the holding period of your underlying shares under the qualified covered call rules. In Canada, the CRA treats premiums as either capital gains or income depending on your trading activity and intent. Always consult a qualified tax professional before starting a covered-call program.

What happens if the premium percentage seems too high?

A very high premium — say, 8% or more per month — usually signals that the market expects a large move in the stock, such as an upcoming earnings report or a news event. The Options Industry Council (OIC) notes that implied volatility spikes around events like earnings, inflating premiums. Selling into those spikes can be profitable, but if the stock moves sharply against you, the premium rarely covers the loss.

Should I pick a higher premium or a higher strike price?

It depends on your priority: income now versus keeping more upside. A higher strike gives your stock more room to run before getting called away, but pays a lower premium. A lower strike (closer to the current price) pays more premium but caps your gains sooner. Most traders find a balance by targeting a delta between 0.15 and 0.30, which typically corresponds to strikes 3% to 8% out-of-the-money.
