Market sizing
Also called guesstimate, sizing question.
Estimating the size of a market from first principles, usually because no reliable published figure exists.
Market sizing works through a chain of quantities you can defend: population, the share in the relevant segment, frequency of purchase and price. For a category bought four times a year at ₹350 by 22% of 140 crore people, the arithmetic gives ₹43,120 crore, better quoted as roughly ₹43,000 crore.
State each link, so that a reader who disagrees can point to one number and leave the rest of the chain standing. Then sanity-check the estimate against something known, such as the revenue of the largest player.
Structure first, numbers second, check third.
