Market Sizing & Forecasting in India

Reliable TAM, SAM and SOM estimates with clear assumptions.

Quick answer

Use this method when the question calls for a reconciled estimate with a visible method. Market Research India runs 10–25 validation interviews over 4–8 weeks, in 50 Indian cities and fourteen languages.

Questions this method is built to answer

Commission this when one of the questions below is holding up a decision. If your question is not on the list, say so in the brief — we would rather recommend a different method than sell you this one.

How large is this market in India today, in value and in volume?
What is realistically addressable for a company like ours?
How fast is it growing, and what is actually driving the growth?
How does the number split by segment, channel and city tier?
What would have to change for the forecast to be wrong?

How we run it

5 stages, with one research director accountable across all of them. The person who scopes the study is the person who presents the findings.

1
Agree definitions before numbers
What counts as in the market, in value or volume terms, is settled first. Most sizing disputes are definition disputes.
2
Build top-down
Published, official and association data is assembled into a top-down estimate with every source dated and its reliability noted.
3
Build bottom-up independently
A separate build works from units, outlets or users upward, constructed without reference to the top-down number.
4
Reconcile and validate
The two estimates are compared, the gap is investigated rather than averaged, and the result is tested with supply-side interviews.
5
Forecast by scenario
Growth is projected under base, upside and downside cases, each driven by named assumptions you can change in the workbook.

Market Sizing & Forecasting — typical study parameters

Typical scale: A full TAM, SAM and SOM model with 10 to 25 supply-side and expert validation interviews
Fieldwork window: Four to eight weeks
Lead time: Desk build starts immediately; validation interviews begin in week two
Coverage: National, state or city-level, with segment splits agreed before modelling starts
Languages: Trade and supply-side interviews in the local language
Core methods: Top-down modelling · Bottom-up builds · Supply-side checks · Scenario forecasting
Reporting: A live market model, a five-year forecast and segment sizing with every assumption named
Best suited to: Putting a defensible number on an opportunity

What you receive

3 named deliverables, each written to be used rather than filed. Everything ships with the underlying data, so your team can keep working after the debrief.

Market model
A live workbook, not a static chart: change an assumption and the market size and forecast recalculate in front of you.
Five-year forecast
A five-year projection under three scenarios, with the driver behind each one stated and sourced.
Segment sizing
Segment, channel and city-tier splits that reconcile to the total, so the detail and the headline never contradict each other.

Quality control in the field

Fieldwork in India fails quietly when nobody checks it. These controls are run on every market sizing & forecasting study, by a quality team that reports separately from the field team.

Every number carries its source
Each input in the model names its source, its date and any adjustment we applied, so your team can argue with the assumption rather than the answer.
Built twice, from both directions
Demand is estimated top-down and bottom-up independently. Where the two disagree by more than fifteen per cent, we go back to primary checks before reconciling.
Validated with people in the trade
Assumptions are tested with eight to fifteen operators, distributors or specialists before they harden into a forecast.
An assumption register you can edit
The model is handed over as a live workbook. Change an input and the forecast moves, which is what makes it useful after we leave.
The gap between builds is explained, not averaged
Where top-down and bottom-up estimates diverge beyond tolerance, we find the reason and report it, rather than splitting the difference.

Method choice

Market Sizing & Forecasting, or one of these instead?

Most briefs can be answered more than one way, and the wrong instrument is the most expensive mistake in research. Here is how market sizing & forecasting compares with the two methods buyers most often weigh against it.

	Market Sizing & Forecasting	Market Feasibility Studies	Competitor Analysis
Best used for	Putting a defensible number on an opportunity	Deciding whether, where and how to commit capital	Knowing what rivals are actually doing, not what they announce
Typical scale	10–25 validation interviews	15–40 stakeholder interviews	5–15 competitors
Fieldwork window	4–8 weeks	6–10 weeks	3–6 weeks
Evidence produced	A reconciled estimate with a visible method	A defensible go or no-go with the assumptions exposed	Observed pricing, placement and win-loss reasons
Projects to a population
Relative cost	Fixed fee by scope	Fixed fee by scope	Moderate, lower when continuous

Where this method stops

Precision is not accuracy. Treat a market size as a range with named assumptions, not as a single number for a slide.

City coverage

Where this work is strongest

We field in all 50 cities, but these are the markets where this method has the most to offer — because of the infrastructure, the respondent base or the sectors concentrated there.

Frequently asked questions

How long does a market sizing & forecasting project take?

Four to eight weeks. Desk build starts immediately; validation interviews begin in week two. Analysis and reporting add a further one to two weeks, so most studies close inside six to ten weeks from brief to debrief.

What sample size do you recommend?

A full TAM, SAM and SOM model with 10 to 25 supply-side and expert validation interviews. The right number is set by the smallest subgroup you need to report separately, not by a round figure, and we will say when a smaller sample would answer the question just as well.

What drives the cost of market sizing & forecasting in India?

Incidence and audience difficulty first, then scale, the number of cities and languages, and the depth of reporting. Relative to other methods on this site, the cost profile is: fixed fee by scope. Send a brief and you get a fixed-fee proposal within 24 hours.

When is market sizing & forecasting the wrong choice?

Precision is not accuracy. Treat a market size as a range with named assumptions, not as a single number for a slide.

How do you control quality in the field?

Each input in the model names its source, its date and any adjustment we applied, so your team can argue with the assumption rather than the answer. Beyond that, the gap between builds is explained, not averaged: where top-down and bottom-up estimates diverge beyond tolerance, we find the reason and report it, rather than splitting the difference.

Can international teams commission this from outside India?

Yes. We report in English, run calls across US, European and Asian time zones, and handle local-language fieldwork and translation end to end.
