Market sizing: estimate Airbnb's yearly fee revenue from the Indian market
Company: Airbnb
Role: Product Manager
Category: Product / Decision Making
Difficulty: medium
Interview Round: Other
Estimate how much revenue Airbnb earns in India in a year. Walk through your approach out loud: define what counts as revenue, build the estimate from assumptions you can defend, do the arithmetic, and check whether the result is plausible.
```hint Bookings first, Airbnb's cut last
Airbnb's revenue is a share of what guests pay. Estimate the value of stays booked first, then apply that share, and size domestic and foreign travelers separately because they behave differently.
```
### Clarifying Questions
- Does "revenue" mean Airbnb's own fees, or the full amount guests pay for stays booked through it (gross booking value)?
- Should the estimate cover stays located in India (booked by Indian and foreign guests), money spent by Indian residents on stays anywhere in the world, or both?
- Should the answer be in Indian rupees or US dollars, and for which recent year?
- Should experiences and other non-stay products be included?
### What a Strong Answer Covers
- A clear revenue definition and scope that separates booking value from Airbnb's share of it.
- A transparent equation in which each driver (travelers, Airbnb's share of bookings, nights, price per night, take rate) is estimated from labeled assumptions that suit India.
- Correct arithmetic with consistent units and currency.
- A sanity check from an independent angle, such as host supply, and a range showing which assumptions matter most.
### Follow-up Questions
- Rebuild the estimate from the supply side, starting from the number of listings. How close do the two answers land, and which would you trust more?
- Which single assumption moves your answer the most, and how would you pin it down with real data?
- If Airbnb wanted to double this revenue in India within a few years, which lever in your equation would you push first?
Overview: An estimation exercise asking candidates to size the revenue Airbnb earns in India each year. It tests defining revenue versus booking value, building a clear equation from labeled assumptions about Indian and foreign travelers, doing the arithmetic correctly and sanity-checking the result from another angle.
