The Baggies are currently three points above the relegation zone on 33, with four games left to play.
"If we consider that West Ham are safe with 37 - that's also what we need," Mel told reporters. "Last year, 36 was actually the cut-off point. I think 37 will be enough to keep us up."
Cardiff City, Fulham and Sunderland currently occupy the bottom three spots in the standings.
