The expenditure and income approaches to calculating GDP arrive at the same final number, but they calculate that number in different ways. To illustrate, consider the possible effects of the following transactions on GDP: 1. Daesun pays Awesome Foods Market $1,100 to cater his daughter's engagement party. He's attracted by Awesome Foods Market's guarantee that he'll be happy with the catering, or he'll get his money back.
2. Awesome Foods Market pays JoAnn's Catering $950 to cater the party.
3. JoAnn's Catering buys plasticware worth $200 from Kostko.

Explanation:

Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year

GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export

Net export = exports – imports

When exports exceed import there is a trade deficit and when import exceeds import, there is a trade surplus.  

Consumption spending includes spending by households on goods and services. Consumption spending includes :  

spending on durables - e.g. laptop  

spending on nondurables - e.g. clothes, food

spending on services  - e.g. payment of hospital bill  

the purchase of a textbook by a student is an example of consumption spending on durable goods

Investment - It includes purchases of goods and services made by businesses in the production of goods and services

the airplane purchased by the airline would be used to provide services for airline customers. Also, the packing boxes bought by Amazon would be used in delivering goods to customers  

Government spending - It includes government consumption expenditure and gross investment.  The purchase of a new  limousine for the president is an example of consumption expenditure
