A credit roll pays you to extend. That is the case worth taking, but check what the new strike does to your breakeven, not just the sign of the ticket. Commissions are counted on both legs, because a roll is two transactions whether or not your broker prices it as one.
Results are arithmetic on the numbers you type. No market data is fetched, and nothing here accounts for early assignment, dividends, taxes, or the bid-ask spread you would actually cross.
