Analysis of Congressional Budget Office projections by the Senate Budget Committee finds that Obamacare will increase the deficit by more than $100 billion over the next decade.
The Congressional Budget Office (CBO) has not actually scored the deficit impact of Obamacare since the summer of 2012.  

At that time, it estimated that Obamacare would reduce deficits by $109 billion over a decade.  But that was for the 2013-22 budgetary window.  Using growth rates derived from that estimate, Senate Budget Committee (SBC) staff found that this $109 billion budgetary surplus for 2013-22 would have become a $180 billion budgetary surplus for 2015-24, if nothing had changed in the interim.
