Pricing a Never-Replace Toothbrush: Lifetime Value Estimate and Launch Price
Company: Amazon
Role: Product Manager
Category: Product / Decision Making
Difficulty: medium
Interview Round: Other
Suppose your team has developed a toothbrush that lasts a user's entire life, so it never needs replacing. How would you price it? Walk through your approach, the estimates behind it, and the launch price you would recommend.
```hint Value of what it replaces
Estimate what a buyer would otherwise spend on toothbrushes over the years this one covers, then ask how much of that a buyer would really hand over in a single payment today.
```
### Clarifying Questions
- Is it a manual or a powered brush, and does "lasts a lifetime" cover the bristles too, or only a handle that takes replacement heads?
- Which market launches first, and through which sales channels?
- What is the business goal: maximum profit, fast market share or building a brand?
- Has the durability and hygiene claim been verified by dentists or independent testing, and will the brush carry a guarantee?
### What a Strong Answer Covers
- A business goal and target segment that set the pricing strategy
- An estimate of the lifetime toothbrush spend the product replaces, with labeled assumptions and correct arithmetic
- Why buyers will not pay that full amount upfront: the time value of money, doubt about the claim, and the risk of losing or tiring of the product
- A cost floor and competitive reference points that lead to a specific recommended price
- How the price is validated after launch, and the business risk of a product that is never bought again
### Follow-up Questions
- Retailers are reluctant to stock it because it ends their repeat toothbrush sales. How does that affect your price and channel?
- Six months after launch, sales are below plan. Do you cut the price, and what else could you change?
- Would you sell a family pack, and how would you price it?
Overview: A product pricing question about setting the price of a toothbrush built to last a user's entire life. It tests choosing a target segment, estimating the lifetime toothbrush spend it replaces, adjusting for upfront payment and buyer doubt, and recommending and validating a launch price for a product that is bought only once.
