The former India captain, who turns 44 in July, led Chennai to a 83-run win over Gujarat Titans on Sunday, but his side finished bottom of the Indian Premier League table.
“There’s no hurry to decide what needs to be done,” Dhoni said after the match.
“Every year, it’s 15% more effort to keep the body fit – not to forget this is top-level cricket.
“It’s professional cricket – you have to be at your best – and it’s not always performance that you can count, because if cricketers start retiring because of performance then a few of them will retire when they’re 22.”
Dhoni has scored 196 runs in 13 innings this season, with a high score of 30, taking over the captaincy after an injury to Ruturaj Gaikwad.
CSK head coach Stephen Fleming has said that Dhoni, once known as one of the game’s great finishers, now “can’t bat for 10 overs” because of problems with his knees.
“What is important to see is how much hunger you have, what kind of fitness you have, and how much you can contribute to the team, and whether the team needs you or not,” Dhoni added.
“I will go back to Ranchi – haven’t been home for a long time – enjoy a few bike rides.
“I’m not saying I’m done, I’m not saying I’m coming back. As I said, I have the luxury of time. When you have the luxury then why not think about it and then decide?”
