Weekly covered calls produce roughly 15-25% more annualized premium than monthly calls because theta decay accelerates in the final 7 days. But after accounting for transaction costs, wider bid-ask spreads, and the time you spend managing positions, monthly calls often net about the same or more for most traders.

The Math: Weekly vs Monthly Premium

Let's use AAPL at $190 with a 0.25 delta call:

Weekly (7 DTE):

  • Premium per week: $1.20
  • 52 weeks/year: $62.40 annualized
  • Percentage: 32.8% of stock price

    • Monthly (30 DTE):

  • Premium per month: $3.40
  • 12 months/year: $40.80 annualized
  • Percentage: 21.5% of stock price

    • Weeklies win on raw premium by about 50% more annualized income. But this comparison ignores real-world friction.

    Real-World Costs That Erode Weekly Profits

    Transaction costs: 52 trades/year vs 12. Even at $0 commission, the bid-ask spread costs you $0.03-$0.10 per contract per trade. Over 52 trades: $1.56-$5.20 per year in spread costs. Over 12 trades: $0.36-$1.20.

    Wider relative spreads on weeklies: Weekly options often have wider bid-ask spreads as a percentage of premium. A $1.20 weekly might have a $0.10 spread (8.3% slippage). A $3.40 monthly might have a $0.12 spread (3.5% slippage).

    Management time: Rolling, monitoring, and closing 52 positions per year is significant work compared to 12.

    Gap risk: Every Monday through Wednesday, your weekly call can get blown through by overnight news. Monthly calls spread this risk across more days.

    After Friction: Adjusted Comparison

    | Factor | Weekly | Monthly | Gross premium$62.40/year$40.80/year Spread costs (52 vs 12 trades)-$3.12-$0.72 Suboptimal fills-$2.00-$0.50 | Net premium | $57.28 | $39.58 |

    Weeklies still win, but the gap narrows from 53% to 45%. And this doesn't factor in the value of your time.

    When Weeklies Make Sense

  • You trade full-time and monitoring positions is part of your day
  • Highly liquid underlyings like SPY, QQQ, AAPL, TSLA where weekly bid-ask spreads are tight
  • You want maximum flexibility to adjust strikes based on weekly price action
  • High IV environments where even 7-day options pay well

    • When Monthlies Make Sense

  • You have a day job and can't monitor positions daily
  • Lower liquidity stocks where weekly options have poor volume
  • You value simplicity — 12 trades per year is easy to manage
  • Smaller accounts where spread costs eat into thin premiums

    • The 45 DTE Sweet Spot

    Many professional option sellers use 45 DTE (days to expiration) as their default. It sits between weekly and monthly and offers:

  • More premium than 30-day calls
  • Favorable theta curve — most theta decay happens in the back half
  • Ability to close at 50% profit in 20-25 days and re-sell

    • With 45 DTE, you get roughly 8-9 cycles per year instead of 12 or 52. The premium per cycle is higher, and the management burden is lower.

    OptionsPilot displays premium yield across all available expirations so you can compare weekly, monthly, and 45-DTE options side by side for any stock.

    My Recommendation

    Start with monthly (30 DTE) covered calls. Get comfortable with the mechanics, management, and psychology. After 6 months, if you want more income and can handle the workload, try weeklies on one position. Compare your actual results — including all friction costs — before switching your whole portfolio.
