The 34-year-old's current deal with the Old Trafford outfit expires in the summer and United boss Sir Alex Ferguson says he will offer the veteran player a one-year extension at the end of the season.
However, Ferdinand has struggled with a back injury in recent years and wants to take his time before deciding whether to continue playing football.
"It's always good to hear the manager say things like that but you have to take every week and month as it comes," Ferdinand told Inside United magazine.
"The best thing I can do is to look at it at Christmas, and then again in the summer to see how I'm feeling and go from there.
"But hearing the manager say things like that definitely puts the spring back in your step.
"I'll have a better idea of that in December or January time when the games start coming thick and fast. That is when it really hits you and you know the hard work really has to start.
"I'll probably get a better gauge of where I'm at fitness wise and the benefit of having the summer off then."
Despite Ferdinand's recent injury woes, he has made over 10 appearances for United this season and more pleasingly for Ferguson it has come at a time when the club's defensive resources have been stretched to the limit.
Ferdinand joined United in 2002 on a five-year deal from Leeds.
