A delta 30 call has roughly a 30% chance of being exercised — meaning 70% of the time, you keep the full premium and continue holding your shares.
Moving from delta 20 to delta 30 typically increases premium collected by 30–60%, depending on the stock's volatility skew. On high-IV names this difference can mean an extra $200–500 per contract per month.
