The American will tee off in the final major of the year, the US PGA Championship, on Thursday, where he is looking to build on his third-placed finish at The Open.
Woods, who has enjoyed a resurgence in form with three wins this year, has been stuck on 14 since lifting the 2008 US Open at Torrey Pines.
However, the 36-year-old believes that he still has plenty of time to match or better Nicklaus's feat.
"I figure it's going to take a career - a long time," said Woods. "Jack didn't finish his until he was 46, so if you go by that timetable I've got 10 more years.
"Four more majors is a lot, but I've got plenty of time."
Woods said that he is desperate to land his 15th major at Kiawah Island, South Carolina, this week.
"I'm pleased at the way I was able to play at certain times [in this year's majors] and obviously disappointed that I did not win," he added.
"I've played in three major championships this year and I didn't win any of them. That's the goal.
"I was there at the US Open after two days and I was right there with a chance at the British Open. Things have progressed, but not winning a major championship doesn't feel very good."
Woods is a four-time winner of the US PGA Championship.
