Projected US budget for the ISS is too low, says report

New Scientist : The transition to commercial companies for transporting astronauts to the International Space Station (ISS) may cost more than NASA has estimated. The agency expects that over the next 10 years its contribution to the ISS will be between $3 billion and $4 billion per year. But according to a recent report by NASA’s internal auditor, that projection is too optimistic and will probably be more. Much of the increase will likely come from higher transportation costs because NASA originally based its estimate on what the US will be paying Russia in fiscal year 2016 for seats on its Soyuz spacecraft. However, Boeing and SpaceX, the two private US companies that have been granted contracts, will probably charge more.
