The 36-year-old forward opted to swap a League One relegation battle with parent club Hartlepool for one in the Championship at the end of last month and, although yet to score for the Owls, has made five appearances already since arriving at Hillsborough.
"There are three games left and we've just got to go until the end and see where we can get to and then we'll take it from there," Howard told the club's official website.
"It's so tight and everybody is beating everybody, but with the form we've been in of late, and with the crowd fully behind us, I'm sure we'll be ok."
Wednesday, who are three points above the drop zone, could take a giant leap towards safety with victory over Ipswich on Saturday.
Howard added: "We've played well over the last five or six games, obviously we had the one blip against Leeds, but we've had some cracking results of late."
