| Concept | Definition / Formula |
|---|---|
| GDP | Monetary value of all final goods & services produced within a country's domestic boundaries in a year |
| NDP | NDP = GDP – Depreciation |
| Nominal GDP | GDP without adjusting for inflation |
| Real GDP | GDP at constant prices. Nominal GDP need not exceed real GDP; the ordering depends on price levels, and they are equal in the base year |
| GDP Deflator | (Nominal GDP ÷ Real GDP) × 100 |
| GDPmp | GDPmp = GDPfc + (Indirect Tax – Subsidies) |
| GDPfc | GDPfc = GDPmp – Indirect Tax + Subsidies |
| GDP at Constant Price | Real/volume measure at reference-year prices; current GDP base year: 2022–23, replacing 2011–12 in the series released on 27 February 2026 |
| GNP | GNP = GDP + Net Factor Income from Abroad |
| NNP | NNP = GNP – Depreciation |
| GVA | Value of output minus value of intermediate consumption; measures contribution to growth by a producer, industry, or sector |
CE = Compensation of Employees; OS = Operating Surplus; MI = Mixed Income; CFC = Consumption of Fixed Capital
OR
Green accounting adjusts conventional national-income measures for natural-resource depletion and environmental degradation; exact frameworks differ.
| Method | Description |
|---|---|
| Production / Value Added Method | Sum value added across producers/sectors; avoid double counting intermediate consumption |
| Income Method | Sum incomes generated in production: employee compensation and operating surplus/mixed income, with relevant tax/subsidy adjustments for the valuation measure |
| Expenditure Method | C + I + G + (X – M), where C = Private final consumption, I = Investment, G = Govt. Expenditure, X–M = Exports minus Imports |
During the first three decades after Independence, India's real economic growth averaged about 3.5% annually — a period termed the "Hindu Rate of Growth."
