The 33-year-old's current contract with the Nerazzurri runs out in the summer of 2014.
"I love it here at Inter and I intend stay until my contract expires in 2014," he told reporters.
"Anything can happen in football, though. It also depends on what the club want to do."
Milito, who has been at Inter since 2009, scored in his side's 3-1 victory over Chievo at the San Siro in Serie A on Sunday.
