How much money did Austria-Hungary spend in World War 1?

The total cost of World War I to Austria-Hungary is difficult to determine precisely due to the complex nature of the war and the subsequent collapse of the Austro-Hungarian Empire. However, it is estimated that the war cost Austria-Hungary approximately 20 billion gold crowns, which was equivalent to about $4 billion at the time. This figure is based on estimates of military expenditures, economic losses, and war-related debts incurred by the Austro-Hungarian government.

The war had a significant impact on the economy of Austria-Hungary, leading to high levels of inflation, shortages of goods, and a general disruption of economic activity. The war also resulted in the loss of territory and resources after the empire's defeat, further exacerbating the economic challenges faced by Austria-Hungary.
