The Balance of Trade (BoT) only includes the value of a country's exports and imports of visible goods (or merchandise). It does not include trade in services, income, or financial assets. The BoT is calculated as:
\[ \text{Balance of Trade} = \text{Value of Exports of Goods} - \text{Value of Imports of Goods} \]
It is the largest component of the current account in the Balance of Payments.
