FORMULA 1 — GNP from GDP:
GNP = GDP + Net Factor Income from Abroad (NFIA)
NFIA = Income earned by Indians abroad MINUS Income earned by foreigners in India
FORMULA 2 — NDP (Net Domestic Product):
NDP = GDP - Depreciation
(Depreciation = wear and tear of machines/assets)
FORMULA 3 — NNP (Net National Product):
NNP = GNP - Depreciation
NNP at Market Price = NNP at Factor Cost + Indirect Taxes - Subsidies
NNP at Factor Cost is also called NATIONAL INCOME
FORMULA 4 — GDP Deflator (Price level measure):
GDP Deflator = (Nominal GDP / Real GDP) x 100
FORMULA 5 — Inflation Rate:
Inflation Rate = ((Price Index Current Year - Price Index Previous Year) / Price Index Previous Year) x 100

INFLATION — EXPLAINED SIMPLY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Inflation means prices go UP over time. Your Rs. 100 buys LESS than it did last year. That is inflation.
Types of Inflation:
• Demand-Pull Inflation: Too much money chasing too few goods. People want more than what is available. Prices rise.
• Cost-Push Inflation: Production becomes expensive (oil prices rise, wages rise). Companies charge more. Prices rise.
• Stagflation: HIGH inflation + LOW growth + HIGH unemployment together. Worst combination. India faced this in the 1970s.
Key Inflation Indexes used in India:
• WPI (Wholesale Price Index): Measures price at WHOLESALE level. Base Year = 2011-12. Managed by Ministry of Commerce.
• CPI (Consumer Price Index): Measures price at RETAIL/CONSUMER level. Base Year = 2012. Managed by Ministry of Statistics (MOSPI). RBI uses CPI to set monetary policy.
• RBI's inflation TARGET = 4% (with band of 2% to 6%) — set under Flexible Inflation Targeting framework since 2016.
