During a surprise trip to Kyiv this week, US President Joe Biden announced an increase in US military assistance to Ukraine of nearly $500 million.
The US has already invested billions in the conflict between Ukraine and Russia. In just 2022, the Congress appropriated over $112 billion (£92 point 47 billion).
In terms of financial contributions, the US is Ukraine's biggest supporter.
However, a year after Russia's invasion, some Americans are questioning where the funding goes and whether the assistance is worthwhile.
The US had already promised to give Ukraine close to $80 billion in aid before Mr. Biden's announcement this week. According to the Kiel Institute for the World Economy, which keeps tabs on international aid to Ukraine, this is the case.
Military aid makes up about $46.6bn of the US commitment, far more than any other nation is contributing. With $51 billion in military aid, the UK comes in second, followed by the EU with $101 billion.
But that's just military assistance. Additional forms of aid raise the price.
In addition to training, logistics, and intelligence support, military aid also covers the cost of tanks, missiles, drones, and other munitions systems. Financial and humanitarian assistance are optional.
Food assistance, clean drinking water, medical supplies, and other necessities for Ukrainians displaced by the conflict are all included in humanitarian aid. Economic aid is provided. By paying government employees, medical professionals, and educators, it keeps Ukraine's government in operation.
More than half of the money the US spends on Ukraine goes toward military assistance, leaving $3 point 96 billion for financial assistance and $26 point 73 billion for humanitarian assistance.
When commitments are ranked according to their proportion of GDP, the US is not the top spender.
According to the Kiel Institute, Estonia tops that list with a pledge of 1 percent of its GDP. The US, on the other hand, is only committing 0.04% of its GDP.
Despite leading the world in terms of the amount of money donated to Ukraine, the US comes in fifth place on this list of donors.
The US is leading the way as money continues to flow into the conflict from all over the world. The Kiel Institute, a German research organization, points out that the cost is still considerably lower than in earlier wars.
According to Kiel, the United States, for instance, spent more than three times as much annually on the war in Afghanistan after 2001.
German commitments to the Allies during the 1990–1991 Gulf War were more than three times greater than its commitments to Ukraine.
