Everton boss Roberto Martinez has previously confirmed that he wants to keep the 33-year-old and Barry is keen to ensure he makes the right decision regarding his future.
"The manager made it clear we'll discuss things in the summer and to concentrate on football, that's what I need to do," Barry is quoted in The Sun.
"Let's focus on the end of the season, hope it is successful and take it from there.
"I'm 33 so it will probably be my last contract. I want to make sure it is the right one."
