The six-time Olympic champion had previously suggested that he would bow out after the 2016 Games in Rio de Janeiro, but he hinted that he could elect to continue in the sport for one extra year.
"I think that my sponsors and everybody wants me to continue so I've really sat and thought about it and maybe I will go on for one more year, and just make everybody happy," he told AFPTV.
"My fans also are saying I should go on, so I think I might do another year."
Bolt also expressed enthusiasm to take part in the Commonwealth Games, having never previously competed in the quadrennial event for nations from the former British Empire.
"I have said to my coach that I would love to go to the Commonwealths," he said.
"It's something that I haven't done before. It's up to him, but I have said to him that I want to be a part of it. My coach will think about it and we will see what he says. I am not 100 per cent sure. We will discuss and see what he says."
Bolt was speaking at a book signing for his new autobiography, "Faster than Lightning" in central London.
