### GDP Calculator - Gross Domestic Product by Income Approach, Expenditure

This tool calculates Gross Domestic Product (GDP) for products current market value in country by Income Approach, Expenditure methods.

#### What is GDP?

### GDP (Y) = C + I + E + G

Where,
Y represents GDP
C represents Consumer spending

E represents Excess of exports over imports
G represents Government spending

 Consumer Spending : Investment made by Industry : Excess of Exports Over Imports : Government Spending : Gross Domestic Product :

# GDP (Gross Domestic Product) by Income Approach Calculator

## Formula:

### GDP = COE + GOS + GMI + TP & M - SP & M

Where,
COE represents Compensation of employees
GOS represents Gross operating surplus
GMI represents Gross mixed income

 Compensation of Employees : Gross operating Surplus : Gross mixed Income : TP & M : SP & M : GDP (Y) :

# GDP (Gross Domestic Product) by Expenditure Calculator

## Formula:

### Y = C + I + G + net exports(X - M)

Where,
C represents consumption
I represents investment
G represents government spending
X represents exports
M represents imports

 Consumption (C) : Investment (I) : Government Spending (G) : Net Exports (X) : Net Imports (M) : GDP (Y) :
