The Reference Design Report estimated the cost of building the ILC, excluding R&D, prototyping, land acquisition, underground easement costs, detectors, contingencies, and inflation, at US$6.75 [[1000000000 (number)|billion]]<ref>{{cite news|url=https://www.nytimes.com/2007/02/08/science/08cnd-collider.htm|title=Price of Next Big Thing in Physics: $6.7 Billion|publisher=NYTimes | first=Dennis | last=Overbye | date=2007-02-08 | access-date=2010-05-05}}</ref> (in 2007 prices).  From formal project approval, completion of the accelerator complex and detectors is expected to require seven years.  The host country would be required to pay $1.8 billion for site-specific costs like digging tunnels and shafts and supplying water and electricity.

Former U.S. Secretary of Energy [[Steven Chu]] estimated the total cost to be US$25 billion. ILC Director [[Barry Barish|Barish]] said this is likely to be an overestimate. Other Department of Energy officials have estimated a $20 billion total.<ref>{{cite web|url=http://blogs.sciencemag.org/scienceinsider/2009/05/chu-pegs-ilc-co.html |title=Chu Pegs ILC Cost at $25 Billion |publisher=ScienceInsider |year=2009 |url-status=dead |archive-url=https://web.archive.org/web/20100105091936/http://blogs.sciencemag.org/scienceinsider/2009/05/chu-pegs-ilc-co.html |archive-date=January 5, 2010 }}</ref> Upon completion of the 2013 ILC Design Report, Barish said the cost of building the ILC was the equivalent of 7.78 billion 2012 U.S. dollars; it will require "22.6 million hours of labor and location-specific costs including site preparation, scientific detectors and facility operations."<ref>{{Cite news|url=http://www.symmetrymagazine.org/article/february-2013/linear-collider-plans-move-forward|title=Linear collider plans move forward|last=Tuttle|first=Ken|date=2013-02-22|work=symmetry magazine|access-date=2017-03-08|language=en}}</ref>
