Gross Domestic Product (GDP)

Total value of all goods and services produced within a country.

  • Formula (Expenditure Method): GDP=C+I+G+(X−M)
  • Use in Exams: GDP growth is one of the most common questions in NABARD Phase 1 GA section.

Gross National Product (GNP)

Consumer Price Index (CPI)

Wholesale Price Index (WPI)

Price index at the wholesale level.

Inflation Rate

Percentage change in CPI or WPI compared to the previous year.

  • Formula: Inflation Rate (%)=((CPIt−CPIt−1)/(CPIt−1))×100
  • Example Question in Exam: “If CPI rises from 110 to 121, what is the inflation rate?”
