GDP — Gross Domestic Product

Gross Value Added measures output the way a producer sees it — the value each industry (agriculture, mining, manufacturing, services) adds at "basic prices," before the government's hand enters the picture. GDP is the buyer's-side total, and the bridge between the two is simple: GDP = GVA + Net Taxes on Products (taxes the government collects on goods and services, minus the subsidies it pays out on them). For FY25-26, Real GVA came in at ₹294.40 lakh crore; add Net Taxes on Products of ₹28.18 lakh crore and you land exactly on Real GDP of ₹322.58 lakh crore. Economists watch GVA specifically when they want to know how industries are actually performing, stripped of the noise of tax policy changes — a GST rate cut can move GDP without a single extra unit of anything being produced.

GDP counts everything produced inside India's borders, regardless of who owns the factory or the capital. Gross National Income (GNI, the modern name for what used to be called GNP) instead follows ownership: it adds Net Factor Income from Abroad (NFIA) — the income Indians and Indian companies earn on assets and labour abroad, minus what foreigners earn on assets and labour inside India. For FY25-26, Nominal GDP stood at ₹357.14 lakh crore against Nominal GNI of ₹351.59 lakh crore — meaning India's NFIA is negative, by about ₹5.55 lakh crore. That can look surprising given how large India's inbound remittances are, but remittances from Indians working abroad are a current transfer, not factor income; the number that actually determines NFIA is profit, dividend and interest repatriation by foreign investors and multinational units operating in India, which currently outweighs what Indian capital and labour bring back from abroad.

Every year, a country's machines, buildings and infrastructure wear down a little — a phenomenon national accountants call "consumption of fixed capital," and everyone else calls depreciation. Net Domestic Product is simply GDP minus that depreciation: it's the output figure once you set aside the portion that merely replaces capital that has worn out, rather than adding anything new to the country's productive capacity. NDP is the more honest measure of how much richer a country actually got in a year, but GDP remains the headline number worldwide mostly because depreciation is harder to estimate precisely and less timely to publish than gross output.

Nominal GDP values output at the prices actually prevailing that year; Real GDP strips out the effect of price changes by valuing output at fixed base-year prices, so what's left is a measure of physical output growth alone. The gap between the two is a direct read on how much of a year's "growth" was actually more stuff, versus just higher prices for the same stuff. For FY25-26, Nominal GDP was ₹357.14 lakh crore against Real GDP of ₹322.58 lakh crore — a gap of roughly ₹34.56 lakh crore, or about 10.7% of the real figure, which is broadly what the economy-wide price level (the GDP deflator) rose by that year. A country can post an impressive-looking nominal growth number purely on inflation; real GDP is the one to trust when the question is "did India actually produce more."

India's per capita Net National Income at current prices reached ₹2,08,090 in 2025-26, up from ₹2,05,324 in 2024-25 — a reminder that GDP growth and living-standard growth aren't the same statistic. Divide any national income aggregate by the population and you get an average, and averages hide distribution entirely: a country can post strong aggregate growth while per-capita gains are concentrated narrowly, or diluted by a still-growing population. Per capita income is the number that gets closer to "how well off is the typical Indian," even though it still says nothing about how that income is actually spread across a billion-plus people.

A haircut that costs ₹150 in Lucknow would cost several times that in London — the same money buys more inside India than it does converted into dollars and spent abroad. Purchasing Power Parity adjusts GDP for exactly this: instead of converting rupees to dollars at the market exchange rate, it converts based on what a common basket of goods actually costs in each country. On a PPP basis, India's economy is valued above $17 trillion by IMF estimates — the world's third largest, behind only China and the US — even though its nominal, market-exchange-rate GDP of a little over $4 trillion ranks it fourth or fifth. Both numbers are "real"; they just answer different questions. Nominal GDP is what matters for things priced in international dollars, like a country's external debt or its imports. PPP is closer to what matters for the everyday purchasing power of the people living inside the economy.
