Trade Deficit or Net Exports is an economic condition wherein the country is importing more goods than it is exporting. The deficit is equal to the value of goods being imported minus the value of goods being exported, and it is given in the currency of the country in question. Trade deficit is an economic measure of a negative balance of trade.

Trade Deficit: where importation > exportation
Deficit = $goods imported - $goods exported
