Scenario

A junior consultant has sized the annual replacement market for a household appliance in Southeast Asia. The number is being used to justify a $111 M capacity investment.

Their working, verbatim

Population is 180m. Average household size is 5, so there are about 36m households.

Penetration of this appliance is 28%.

Appliances are replaced every 6 years.

So annual replacement demand = 180m × 28% ÷ 6 = 8.4m units per year.

At $3396 per unit, that is a market of roughly $28,526 M a year.

The partner has asked you to check it before it goes in the deck.

Your task

Check the estimate. Your answer should provide:

  1. Analysis — find the error and quantify how much it distorts the answer.
  2. Risks — what depends on this number being right.
  3. Recommendation — the corrected size, computed, and how you would sanity-check it.

State any assumptions you make.
