Match Netflix profit; derive required subscribers

Company: Capital One

Role: Data Scientist

Category: Statistics & Math

Difficulty: easy

Interview Round: HR Screen

Assume all figures are monthly. From earlier: break-even used F = $100M, p = $9, v = $4, so contribution margin per subscriber is (p−v). Define “Netflix” as having a subscriber base equal to 4× the break-even subscriber count under those economics, with the same F, p, and v as above. a) Compute Netflix’s monthly profit. b) Now consider your startup with fixed cost treated as F' = $150M (investment to be repaid and thus acting as fixed cost this period), variable cost v' = $4, and price p' = $15 (from producing 30 shows under the WTP curve). How many subscribers do you need to match Netflix’s monthly profit? Show all algebra and units.

Subscription Profit and Break-even (All Monthly)

Assume all figures are monthly and "M" denotes millions.

We model subscription profit as:

  • Profit = Subscribers × (p − v) − F
    • F = fixed cost (USD/month)
    • p = price per subscriber (USD/month)
    • v = variable cost per subscriber (USD/month)

Given earlier: F = 100M,p=100M, p = 100M,p=9, v = $4. Define "Netflix" as having a subscriber base equal to 4× the break-even subscriber count under those economics, using the same F, p, v.

Tasks: (a) Compute Netflix’s monthly profit.

(b) Now consider your startup with F' = 150M(treatedasfixedcostthismonth),v′=150M (treated as fixed cost this month), v' = 150M(treatedasfixedcostthismonth),v′=4, p' = $15. How many subscribers do you need to match Netflix’s monthly profit? Show all algebra and units.
