Two headline numbers, one economy.
India reports two growth figures every quarter, and they never quite agree. The gap between them is exactly one thing, taxes net of subsidies: accounting, not a discrepancy.
The charts on this page draw the national accounts at 2011-12 prices, the series that ran to July to September 2025. The NSO now publishes GDP at 2022-23 prices. The idea on this page works the same on either ruler; the latest figures are in the GDP guide.
Two prices for the same output
First principlesEvery quarter, India reports two headline growth numbers, and they never quite agree. One is GDP, measured at market prices: what buyers pay. The other is GVA, measured at basic prices: what producers receive at the factory gate. The difference between the two is exactly one thing, taxes on products minus subsidies. It is accounting, not a discrepancy.
GDP takes that same production and re-prices it at the till. Add the taxes the government charges on products, subtract the subsidies it pays on them, and the producers' total becomes the purchasers' total. The identity is exact: GDP equals GVA plus net taxes.
A litre of petrol makes it concrete. The refiner and the dealer receive one price; the buyer pays that price plus excise and GST. GVA follows the first figure, GDP follows the second. Neither is wrong. They stand on opposite sides of the till, and each side has its uses.
The same decade, measured twice
y/y %, quarterlyDrawn together, the two measures trace nearly the same path, because they measure the same economy. What separates them is the wedge, and once in the decade the wedge swings hard enough to put the lines in a different order.
Two lines for one economy: the gap between them is the tax wedge
The two lines move together; that is the first thing to see, and it is reassuring. The second thing is the gap. When GDP runs above GVA, product taxes are growing faster than subsidies. When it dips below, subsidies are winning. A swinging gap says something about the government's accounts, nothing about measurement error.
In Q4 FY21 the lines crossed in an instructive way. GVA grew – while GDP grew only –. Production was recovering, but the wedge had swung: subsidy payouts rose sharply in the pandemic year even as tax collections fell.
Same economy, same quarter, two true numbers. Anyone quoting only one of them that quarter told half the story.
Which one to quote, and when
A rule of thumbFor the size and growth of the whole economy, quote GDP. It is the international standard, the budget is framed in it, and the RBI's models consume it. For the health of farms, factories and services, quote GVA: the sector detail lives on the producers' side, and the tax wedge adds nothing to that question.
The everyday error is quoting one when the question belongs to the other. Asking how manufacturing fared and answering with GDP imports the government's tax slice into a question about factory gates. Asking how fast the economy is growing and answering with GVA understates what buyers actually paid. Match the number to the question, and the two headlines stop competing.
How to misread this concept
- i.
“One of them must be wrong.”
No. They answer different questions at different prices. A shop's bill and the shopkeeper's receipt differ by the tax, and nobody calls that a contradiction. GDP and GVA differ by the same logic, at the scale of a country.
- ii.
“Always quote GDP.”
GDP is the right headline for size and international comparison. It is the wrong lens for the sector story. When agriculture or manufacturing is the question, GVA is the cleaner read, because the tax wedge says nothing about how farms and factories fared.
- iii.
“The gap is a data error.”
The gap is defined, not discovered. GDP minus GVA equals taxes on products minus subsidies, by construction. It widens when collections surge and narrows when subsidies do; in the pandemic year it swung hard enough to put GDP growth below GVA growth. That is information, not noise.
