A total of $50.1 billion (equivalent to $656 billion today) worth of supplies were shipped, or 17% of the total war expenditures of the U.S.[2] In all, $31.4 billion went to Britain, $11.3 billion to the Soviet Union, $3.2 billion to France, $1.6 billion to China, and the remaining $2.6 billion to the other Allies. Reverse Lend-Lease policies comprised services such as rent on air bases that went to the U.S., and totaled $7.8 billion; of this, $6.8 billion came from the British and the Commonwealth. The terms of the agreement provided that the materiel was to be used until time for their return or destruction. In practice very little equipment was returned. Supplies that arrived after the termination date were sold to Britain at a large discount for £1.075 billion, using long-term loans from the United States. Canada operated a similar program called Mutual Aid that sent a loan of $1 billion and $3.4 billion in supplies and services to Britain and other Allies.[3][4] The United States did not charge for aid supplied under this legislation.
This program effectively ended the United States' pretense of neutrality and was a decisive step away from non-interventionist policy, which had dominated United States foreign relations since 1931.
