Amazon Prime Fee Increase: Recommendation and Revenue Impact Estimate
Company: Google
Role: Product Manager
Category: Product / Decision Making
Difficulty: medium
Interview Round: Other
Amazon is weighing whether to raise the price of a Prime membership. Should it? If you recommend an increase, estimate how much revenue Amazon would gain or lose as a result.
```hint Revenue moves both ways
A higher fee earns more from members who stay, but members who cancel take away more than their fee. Structure the estimate so you can see how many cancellations the increase can absorb before it stops paying off.
```
### Clarifying Questions
- Which market should I size: the United States only, or Prime worldwide, where prices differ by country?
- Does "revenue" mean membership fees only, or also the retail spending and advertising that Prime members drive?
- Do the benefits stay the same, including fast shipping and video streaming, or does the price change come with benefits added or removed?
- Does the increase apply to both monthly and annual plans, and to discounted plans such as student memberships?
### What a Strong Answer Covers
- A clear objective for the price change, with the decision framed around it rather than around fee revenue alone.
- An estimation structure that separates the gain from members who stay and the loss from members who cancel or downgrade, with labeled round-number assumptions.
- Correct arithmetic plus a break-even cancellation rate or sensitivity range showing when the increase stops paying off.
- Effects beyond the fee: lost shopping from members who leave, cheaper competing memberships, and brand or regulatory risk.
- A recommendation with a way to test or stage the change before rolling it out to everyone.
### Follow-up Questions
- How would you measure the real cancellation effect of a price increase before rolling it out to every member?
- If Amazon offered a cheaper tier with fewer benefits instead of one higher price, how would your estimate change?
- Monthly members can react to a price change right away, while annual members feel it only at renewal. How does that affect the first-year revenue impact?
Overview: A pricing and estimation prompt asking whether Amazon should raise the Prime membership fee and how much revenue the change would add or cost. It tests weighing gains from members who stay against losses from cancellations, labeling assumptions, finding a break-even cancellation rate, and separating fee, retail and profit effects.
