Is there an estimate on how much did the ww2 cost all the countries together?
The rough estimate on how much the Second World War cost each country is around 1 trillion dollars in 1945. In today’s money, that would be around $11,292,682,078,166 dollars, a truly monumental cost. The United States spent the most on the war at around 341 billion ($3.5 trillion in today’s money). These estimates do not include the post-war cost of the conflict, such as the funds needed to rebuild and repair Europe and Asia along with the human cost of so many deaths and injuries across the globe
