Brady, 39, told Sports Illustrated's TheMMQB.com blog that he sees himself playing until his mid-40s provided his fitness holds up.
"I'd like to play until my mid-40s," Brady told the MMQB's Peter King.
"Then I'll make a decision. If I'm still feeling like I'm feeling today, who knows? Now, those things can always change. You do need long-term goals too. I know next year is not going to be my last year."
Brady, who became the second oldest quarterback to win a Super Bowl after Peyton Manning with New England's 34-28 victory over Atlanta on February 5, showed no sign of his advanced years in the showpiece.
The Patriots star threw for a Super Bowl-record 466 yards including two touchdowns in the victory in Houston.
Brady credits his longevity to his monkish lifestyle habits, which includes a strict diet and an exercise regime which emphasizes muscle pliability.
"Other than playing football, the other thing I love to do is prepare to play football. I've worked hard to get a system in place that really works for me and I know could work for everybody else if they just did it," Brady said.
"That enables me to play 99 plays as a 39-year-old in the last game of the season. ... Football to me is more than just a sport. It has become my life. Every choice that I make ... what I have for breakfast, how I work out, all of those things. I love the game. I love playing."
