Determine the indicator's value by using the following methodology:
1) Request the business owner to tell you the amount of his business' income and expenses for each of the assessed month (for example, June 2016, July 2016, August 2016 and September 2016).
2) Verify the amounts by enquiring about further details (e.g. about how many goods/services were sold for which price), requesting relevant documentation (e.g. invoices, payrolls), conducting observations, and crosschecking the information with key informants (e.g. employees or customers).
3) By deducting the expenses from the received income, you will calculate the business' net profit.
4) Calculate the indicator's value by summing up the net profit of the surveyed businesses (for the given time period) and dividing it by the number of surveyed businesses.
