Cost of Persian Gulf War by Country: The cost of the war to the United States was calculated by the United States Congress to be $61.1 billion. About $52 billion of that amount was paid by different countries around the world:
  • $36 billion by Kuwait, Saudi Arabia and other Persian Gulf States;
  • $16 billion by Germany and Japan (which sent no combat forces due to their constitutions).

About 25% of Saudi Arabia's contribution was paid in the form of in-kind services to the troops, such as food and transportation. U.S. troops represented about 74% of the combined force, and the global cost was therefore higher.
