Calculate gross domestic product using the expenditure and income approaches, plus GDP growth rate, real GDP and GDP per capita.
GDP = C + I + G + (X − M) — personal consumption + gross investment + government consumption + net exports. Leave a field blank for 0; negative values are allowed (for example a fall in inventories).
| Component | Amount | Share of GDP |
|---|
GNP = employee compensation + proprietors' income + rental income + corporate profits + interest income. GDP = GNP + indirect business taxes + depreciation + net income of foreigners.
| Component | Amount | Share of GDP |

Fill in whichever fields you need: growth needs the previous period's GDP, real GDP needs a GDP deflator (100 = base year), and per-capita needs the population.

GDP = C + I + G + (X − M): consumption + investment + government spending + (exports − imports). Example: 100 + 30 + 40 + (20 − 25) = 165.
The GDP Calculator computes gross domestic product — the market value of all final goods and services produced in an economy in a period — using the two most common textbook methods. The expenditure approach adds household consumption, investment, government spending and net exports. The resource cost-income approach adds up the incomes earned in production (wages, profits, rent, interest) plus indirect taxes, depreciation and net income of foreigners.
A third tool calculates the GDP growth rate, real GDP using a GDP deflator, and GDP per capita. Use any currency or unit — the label you type is simply shown next to the results. The calculator is handy for economics students, exam practice, project reports and quick what-if comparisons. It does not fetch real statistics; for official figures use national statistical releases.
| Item | Amount |
|---|---|
| Personal consumption (C) | 100 |
| Gross investment (I) | 30 |
| Government consumption (G) | 40 |
| Exports (X) | 20 |
| Imports (M) | 25 |
| Net exports (X − M) | −5 |
| GDP = 100 + 30 + 40 + (20 − 25) | 165 |
| Item | Amount |
|---|---|
| Employee compensation | 120 |
| Proprietors' income | 20 |
| Rental income | 5 |
| Corporate profits | 30 |
| Interest income | 10 |
| GNP | 185 |
| Indirect business taxes | 15 |
| Depreciation | 20 |
| Net income of foreigners | −5 |
| GDP = 185 + 15 + 20 − 5 | 215 |
| Component | What it includes | What it excludes |
|---|---|---|
| Personal consumption (C) | Household spending on goods and services: food, rent, fuel, healthcare, durable goods | Purchase of new housing (counted as investment) |
| Gross investment (I) | Business spending on equipment, factories and software; new housing; changes in inventories | Buying existing assets and financial products (savings) |
| Government consumption (G) | Government spending on final goods and services, including salaries | Transfer payments such as pensions and subsidies |
| Net exports (X − M) | Exports minus imports of goods and services | — |
| Textbook term | Term used by India's National Statistics Office |
|---|---|
| Personal consumption (C) | Private final consumption expenditure (PFCE) |
| Gross investment (I) | Gross fixed capital formation (GFCF), change in stocks and valuables |
| Government consumption (G) | Government final consumption expenditure (GFCE) |
| Exports and imports (X, M) | Exports and imports of goods and services |

India's official GDP is compiled mainly with the production (value-added) approach and cross-checked with expenditure data. Use official releases for actual figures.
| Measure | Meaning | Formula |
|---|---|---|
| Nominal GDP | Output valued at current prices | As calculated above |
| Real GDP | Output valued at base-year prices, removing inflation | Nominal GDP ÷ (GDP deflator ÷ 100) |
| GDP growth rate | Change in GDP from one period to the next | (Current ÷ previous − 1) × 100 |
| GDP per capita | Average output per person | GDP ÷ population |
| GNP | Output produced by a country's residents and factors, wherever located | GDP + net factor income from abroad |
Gross domestic product is the total market value of all final goods and services produced within a country in a given period, usually a quarter or a year. It is the most widely used measure of the size of an economy.
The expenditure approach is GDP = C + I + G + (X − M): consumption plus investment plus government spending plus net exports. The income approach adds up all incomes earned in production plus indirect taxes, depreciation and net income of foreigners.
GDP counts output produced inside a country's borders, whoever owns the factors of production. GNP counts output produced by a country's residents and their assets, wherever in the world. GNP = GDP + net factor income from abroad.
Exports minus imports. A positive number is a trade surplus that adds to GDP; a negative number is a trade deficit that subtracts from it.
Nominal GDP uses current prices, so it rises with inflation. Real GDP is adjusted to base-year prices using the GDP deflator, so it shows genuine growth in output.
(Current GDP ÷ previous GDP − 1) × 100. For example, GDP rising from 200 to 220 is 10% growth. Use real GDP if you want growth without the effect of inflation.
GDP divided by population. It is a rough measure of average output (and income) per person, but it does not show how evenly it is distributed.
GDP counts new production only. Transfer payments such as pensions move money without producing anything, and used goods were counted when first made.
Unpaid household work is not included, and informal activity is only partly captured, because they are hard to measure — so GDP can understate total economic activity.
No. It calculates from the numbers you enter. For official GDP figures, consult national statistical releases such as those of India's National Statistics Office.
