While under U.S. administration, tolls for use of the canal were set at rates calculated to cover costs of maintenance and operation, thereby making the canal self-financing. The charge for each transit was based upon the interior cargo or passenger-carrying capacity of a vessel. The rates established in 1914 remained virtually unchanged for 60 years. In 1973 the canal operated at a loss for the first time, and in 1974 the first of several rate increases went into effect.
Traditionally, cargoes were carried below deck and tolls were assessed on goods carried there. However, because of changes in marine design and the widespread use of containerized cargoes, a large portion of the burden is now carried on deck. The volume of containerized cargo passing through the canal is outranked only by shipments of grain and petroleum products. These changes led to modifications in rules of admeasurement and the assessment of tolls for on-deck container capacity. Following the lead of the Panama Canal Commission, the Panama Canal Authority approved similar changes in admeasurement regulations and retained the U.S. toll rates in effect when the canal was transferred.
From the tolls collected, the Panama Canal Authority must pay an annual fee to the Panamanian national treasury. Any surplus remaining after that and the payment of canal operational and maintenance expenses also goes to the treasury.
