The left-back feels that between 37 and 39 points should be enough to prevent Mark Hughes' side from dropping back into the Championship after just one season in the top flight
The London club currently sit two points clear of 18th-placed Bolton, although Wanderers have two games in hand, and the left-back feels that at least six points are required from difficult fixtures against Tottenham, Chelsea, Stoke City and Manchester City.
“It's difficult to say how many points we will need as it changes every week,” Hill told the Fulham Chronicle.
“Some say 37 points, some say 39 so maybe if we can get in between that then hopefully we'll be safe.”
Given some of the surprise recent results that have turned the relegation fight upside down, though, Hill will be taking nothing for granted.
Fellow strugglers Wigan have recently beaten Liverpool, Manchester United and Arsenal, whilst QPR have also benefited from dramatic wins over the Reds and the Gunners in recent weeks.
But the defender warned: “It's going to be tough.
"Everyone says that some teams have got an easier run-in than others, but there's no easy games in this league. Every team will find that out.
“Hopefully with the big teams we have to play that will raise our game even more.”
