Sneijder has been the subject of a protracted transfer saga with Manchester United but a move has failed to materialise so far due United's reluctance to meet the Dutchman's reported demands of £200,000-a-week wages.
The 27-year-old midfielder has instead focused on helping Inter overcome their dismal start to the season to help the club to fifth in the Serie A and reach the knockout stages of the Champions League.
Despite reports last week that Inter Milan will need to sell Sneijder in order to fund the club, Sneijder is certain that he will remain at the club until at least the end of the season.
He told Voetbal International: "If I must give a percentage for it, I think I am 90 per cent certain I will stay [until at least the summer].
"I enjoy myself here at the moment and at this point I don't have anything to choose from."
Sneijder stopped short of promising that he will stay at Inter on account that an improbable move should happen.
"I don't say that I am 100% certain because something unexpected can always happen."
Inter Milan are reportedly in the chase for Manchester City's wantaway striker Carlos Tevez to boost their Serie A fight which resume on Saturday against Parma.
