Market Feasibility Studies Sample Size and Sampling Guide for India

How to choose the right sample size and sampling approach for market feasibility studies in India, including quotas, city splits and segment reads.

See case studies

Quick answer

The right sample for market feasibility studies depends on how many segments you need to read separately and how precise each reading must be. In India, also plan quotas by city tier, region, age, gender and socio-economic class (NCCS).

Guide type: Methodology · 4 minute read
Method covered: Market Feasibility Studies
Research family: Strategy research
Typical timeline: 6–10 weeks, longer where regulatory or land-approval enquiries are in scope
Typical sample: 15–25 stakeholder interviews plus a demand-side survey of 200–400 potential buyers
Written for: Analysts sizing the sample · Data leads reviewing a design · Anyone asked “is this enough?”

Key takeaways

Plan sample per segment, not just in total
Use NCCS for socio-economic quotas in India
Weight results to match the population
Qualitative samples are about saturation, not statistics

Who this guide is for

Three readers arrive here with different problems. Each should be able to act on this page without reading all of it.

Analysts sizing the sample
How to get from a decision to a defensible market feasibility studies sample, rather than to a round number.
Data leads reviewing a design
Frames, quotas, weighting, and the bases you can and cannot report on.
Anyone asked “is this enough?”
The answer depends on the precision the decision needs. This guide shows how to work that out.

Start with segments

Decide which groups you must compare, for example metro versus Tier 2, or users versus non-users. Each needs a robust base.

Quotas that matter in India

City tier and region
NCCS socio-economic classification
Age and gender

Statistical precision

Larger samples narrow the margin of error, but the gains shrink as samples grow. Balance precision against cost per segment.

How Market Research India can help

Market Research India designs and runs market feasibility studies projects across 50 Indian cities and 30 industries. A senior research director leads every study, and our own supervised teams handle the fieldwork. You get clear recommendations, not just data tables.

Share your objective and we will send a scoped, fixed-fee proposal within 24 hours, with a recommended method, sample and timeline.

What goes wrong

Common mistakes in market feasibility studies

Most disappointing market feasibility studies studies fail for reasons that were visible in the design, not in the fieldwork. These are the ones we see most often, and what to do instead.

01
A top-down market size with no bottom-up check
Multiplying a published national figure by a share assumption is not an estimate, it is a hope. Build demand from units, outlets or households and reconcile the two.
02
Reading stated intent as demand
Purchase intent overstates behaviour everywhere, and by more in interview settings. Discount it, or triangulate against observed proxies such as current category spend.
03
Leaving the approval path out of the timeline
Licences, clearances and local permissions routinely add months. A case that ignores them is optimistic on both cash flow and launch date.
04
A single base case with no downside
A board cannot sanction a number with no range around it. Model base, downside and upside, and state what triggers each.
05
Findings that arrive after the decision
Research timed to land after the investment committee has met is an audit, not an input. Work back from the decision date and cut scope rather than slip.
06
Assumptions buried in the model
A number nobody can trace is challenged once and ignored thereafter. Every assumption on its own labelled line, with its source.

Run through this before sign-off

Your checklist before you brief anyone

A working sequence for a market feasibility studies project. Most of it costs nothing, and it saves the two weeks a re-field would take.

1
Write the go/no-go criteria before the research starts, and have them signed off.
2
Build demand top-down and bottom-up independently, then explain the gap between them.
3
Interview the supply side — distributors, suppliers, competitors — not only prospective buyers.
4
Price the regulatory and approval path in both money and months.
5
Name the two or three conditions under which the recommendation would flip.
6
Name the two assumptions the conclusion is most sensitive to, and test them explicitly.
7
Agree in writing who acts on each finding, and by when, before the debrief ends.
