India's economic output was 8.1% in Q2 2026, and a year out it is expected to be lower than that.
Q3 2026
7.3%
6.8% to 7.8%
Usually within 2.6 of the outcome at this range
Q2 2027
6.4%
5.2% to 7.7%
Usually within 3.9 of the outcome at this range
Even if nothing moved at all, the nearer figure would come out at 5.8%. A year-on-year rate compares with a month that is already history, so that much is arithmetic — what is still open is how much gets added on top.
The ranges are not a feeling about confidence. They are how far this method has actually been off before: half of past outcomes landed inside them, and half outside. The nearer one is tighter because the near future genuinely is more knowable than the far one.
% YoY. Sources: India — OECD. Retrieved 2026-10-13. Everything after the dotted line is a forecast, not a record. The shaded band is where this method has landed half the time in the past — so half the time, outside it. No language model produces any of these numbers.
How far off this forecast has usually been
Every method was replayed from each of the last three years' starting points, seeing only what was known at the time, and scored against what actually happened for India.
The forecast drawn above has landed within 2.60 pp of the outcome on average a quarter ahead, and within 3.94 pp a year ahead.

India, measured over the last 33 starting points. The last column compares each method against the simplest rule there is — assume this period repeats what it did a year ago. Below 1.00 means smaller errors than that rule, above it means worse. All of it is measured against today's revised figures rather than against what was known at the time, which flatters every method here a little.
Where the methods disagree
A year out the methods stop agreeing. The spread is not a flaw to be hidden: it is the honest size of what nobody knows yet, and it is why the chart above draws the middle of them rather than picking a favourite.
India, Q2 2027. The dot is what each method expects, the bar how far it would not be surprised to be wrong. They are run on the same numbers and still land 6.7% apart, which is the honest size of the disagreement — and the reason the chart above draws the middle of them rather than picking a favourite.
