Fulham's Felix feeling confident
Sunday's clash with Everton is the first of four matches at Craven Cottage that will be critical to the club's drive to escape relegation.
Fulham are positioned at the foot of the table four points adrift of safety but Magath, who replaced the axed René Meulensteen on February 14, views only one outcome at the end of the season.
"This job is not tougher than I expected it to be. I knew that it would be a difficult job and it is," he said.
"But I don't worry about that, I'm happy to be here. I'm looking forward and I'm convinced we'll stay in the league.
"I'm not looking at next season because we have to realise that we may not be staying in the Premier League, but I'm convinced that we will."
Should Fulham's 13-season stay in the top flight come to an end in May, Magath insists he will remain at Craven Cottage.
"I'm sure I will still be here, wherever the club is. I'm happy here and want to stay," he said.
Fulham have won just one of their last 13 Premier League games and have secured just 13 points at Craven Cottage all season.
In contrast, Champions League-chasing Everton have won their last four matches.
"Everton are in good shape, we've seen their result at Newcastle last weekend (winning 3-0). It will be our most difficult game here at Craven Cottage," Magath said.
"I don't think about the other teams because we know we have to win games, otherwise we have no chance of staying in the league.
"We have to win because we are a few points adrift, so we need more points than the other teams at the bottom."
Fulham continue to be without £12million Greece striker Kostas Mitroglou, who has yet to recover from a knee injury.
Mitroglou has made only two appearances for the Cottagers since his deadline-day signing in January, but Magath hopes he will return soon.
"Kostas is not happy about being injured, but it's a normal thing for a football player. They get injuries," he said.
"We will see if he can join us in training next week. If there is a risk we will wait longer."
