第二次世界大戦は、金銭的なコストと失われた人命の両方の点で、人類史上最も高価な戦争の1つでした。全体的な経済コストは、その広範な結果と多くの国の関与のために推定するのが困難です。ただし、一部の推定では、総コストは1945ドルで1.5兆ドルから4兆ドルの間であり、これは直接コストや生産性の損失やインフラストラクチャの損傷などの間接コストを含む2023ドルにインフレ率が22兆ドルから60兆ドルに調整されています。
World War II was one of the most expensive wars in human history in terms of both monetary cost and human lives lost. The overall economic cost is difficult to estimate due to its far-reaching consequences and involvement of many countries. However, some estimates suggest the total cost was between $1.5 trillion and $4 trillion in 1945 dollars, which would be between $22 trillion and $60 trillion adjusted for inflation to 2023 dollars, including direct costs and indirect costs such as lost productivity and infrastructure damage.
