The Black Country outfit are bottom of the table with 32 points, but have a game in hand on most of their rivals.
McCarthy believes a total of 41 points would be enough to preserve their league status.
"If somebody gave me that now, I'd take it away and we would be absolutely safe, no question," he said.
"Three wins out of six games, I'd take that all day long. If it takes more than that, we might all have problems."
