Moyes celebrates the 11th anniversary of his time at Goodison Park in a month’s time.
But he has not revealed whether he will extend his contract which expires this summer.
It looks likely that Moyes will keep chairman Bill Kenwright, the players and fans in the dark over the last three months of the campaign.
He said: “I’ll give as much as I can, but I’ve said — and I’ve spoken with the chairman — that I want to see how the team do.
“I want to see how we do in the cups, I want to see how we do in the league, and it’s more than likely I won’t make a decision until the end of the season.
“So you can ask me every week but I’ll probably give you the same answer.”
Moyes’ men face League One outfit Oldham in an FA Cup fifth-round tie, who last month pulled off a stunning upset with a 3-2 victory over Liverpool.
He recalls his side’s own defeat to Oldham five years ago when the underdogs won a third-round clash 1-0 at Goodison Park.
He said: “We know what they can do as they did very well against Liverpool. It was a great result, but that’s what the cup does.
“We’ve been knocked out by Shrewsbury (third round in 2003), knocked out by Oldham.
“I thought we’d prepared well when we went to play Shrewsbury, and again when we played Oldham, but we didn’t get the result, and that is football.
“You have to play well, take your opportunities when they come along, which is cup football because you only have one chance.
“So we have been there, done that, we know what it’s like and we don’t want it to happen again.
“We’ll do everything we possibly can to make sure it doesn’t.”
Meanwhile, the club remain in the hunt for a top-four finish in the Premier League.
However, they have fallen behind slightly of late and now trail Spurs by six points and Arsenal by two in the hunt for a top-four spot.
Moyes said: “Qualifying for the Champions League always means more because the financial rewards from that are far greater than what you get from the FA Cup.
“We can think of a lot of teams who have won the FA Cup and it’s not desperately changed their fortunes, whereas qualifying for the Champions League does.
“If you do that, and you get into the group stages … look what it has done for Celtic, the profits they have made over the last six months, with most of it down to how they have done in the Champions League.”
