Net factor income from abroad and national income

Net factor income from abroad iz symbolically refers to (NFIA) its means that what the labour are income from abroad and what other nation labour income from us

It help to find Gross net profit of the nation by adding NFIA in GNP

This totally used to find national income of the country
To find national income at first we have to calculate GDP its stand for gross domestic product its also find from different idea such as income method and expenditure method and final product method
Lets know how to GDP by income method
GDP=wage +salary+ profit +Net in direct tax +deprecation + interest
From the GDP we can find GNP
GNP=GDP+NFIA
from GNP WE CAN FIND NNP
where as NNP=GNP -deprecation
As last we can find National income
NI=NNP+susidy - indirect tax

Let find NI from expenditure method
GDP= C+I +G(X-M)
where as c= expenditure made by consumer
I= expenditure made by business
G= expenditure made by government
(X-m)=export-import
Now GNP =GDP+NFIA
NNP=GNP-deprecation
At last NP =NNP+susidy-indirect tax

Now lets know how to find national income from final product method
GDP=primary + secondary + tertiary sector
GNP= GDP+NFIA
NNP=GND -DEPRECATION
AT LAST
NI=NNP+susidy-indirect tax
