Break down the revenue and costs over the 12-month tenure, carefully accounting for the 3 free months and one-time fees. Calculate total revenue, total variable costs, and total one-time costs, then compute contribution margin and assess if it's positive.
Pro tip: Always clarify whether the 3 free months are at the start and whether the install fee is charged upfront or amortized; also consider if the onboarding cost is incurred at acquisition. This shows attention to detail and business acumen.
Determine the number of paid months (12 - 3 = 9) and multiply by the monthly fee ($40) to get total revenue: 9 * $40 = $360.
Multiply the variable cost per active month ($25) by the number of active months (12) to get total variable costs: 12 * $25 = $300.
Sum the one-time install fee ($35) and onboarding cost ($20) to get total one-time costs: $35 + $20 = $55.
Subtract total variable costs and total one-time costs from total revenue: $360 - $300 - $55 = $5. This is the per-customer contribution.
Since the contribution is positive ($5), the unit economics are positive, but the margin is thin, indicating potential sensitivity to tenure or cost changes.

I kind of fumbled this because my part (a) answer was positive, so I had to awkwardly hypothesize a negative scenario anyway.
Start by defining the per-customer contribution formula and identifying the negative gap. Then propose two quantitative levers, such as price increase and cost reduction, and calculate the required change for each to close the gap, using a simple numerical example.
Pro tip: Use a concrete example with round numbers to illustrate your calculations, and mention that you would validate assumptions with A/B tests to ensure feasibility and minimize customer churn.
State the formula for per-customer contribution (e.g., revenue - variable costs) and identify the negative gap that needs to be closed.
Propose increasing price by a certain percentage and calculate the new contribution to show it becomes non-negative.
Propose reducing variable costs (e.g., free months, service costs) and calculate the required reduction to achieve non-negative contribution.
Compare the feasibility and impact of each lever, considering customer sensitivity and operational constraints, and recommend a combined or prioritized approach.

First, compute the expected contribution per customer by weighting the outcomes: 10% pay only the $100 penalty, while 90% pay the full contract value (monthly price × 21 months). Then generalize the formula with variables for penalty, monthly price, contract length, and termination probability, and finally set the expected contribution times annual customer count equal to fixed costs to solve for the break-even number of customers.
Pro tip: Always state your assumptions clearly (e.g., no discounting, penalty paid immediately, monthly price constant) and note that in a real business context you'd also consider time value of money and customer acquisition costs.
Assign symbols to key parameters: monthly price (P), contract length in months (L=21), penalty (F=$100), termination probability (q=0.10), and fixed costs (C=$1,000,000). State assumptions such as no discounting and immediate penalty payment.
Calculate the contribution for each outcome: if terminate, contribution = F; if complete, contribution = P × L. Then compute the expected value: E = q × F + (1-q) × (P × L).
Substitute the known values: q=0.10, F=$100, L=21. If P is not given, express the expected contribution as E = 10 + 0.9 × 21P = 10 + 18.9P. If a specific P is provided, compute the numeric value.
Write the general formula: E = qF + (1-q)PL. This can be rearranged as E = qF + PL - qPL = PL - q(PL - F).
Set total expected contribution equal to fixed costs: N × E = C, so N = C / E. Substitute the expression for E to get N = C / (qF + (1-q)PL). If P is known, compute N; otherwise, leave as a formula.

Start by defining the breakeven customer count formula: fixed costs divided by contribution margin per customer, where contribution margin depends on price and variable cost. Then analyze how each variable affects this formula, arguing that cost structure has the most leverage because it directly determines the contribution margin and can be structurally altered. Use a quantitative example to illustrate the impact of a 10% change in each variable on breakeven volume.
Pro tip: Acknowledge that the answer depends on the business context and stage; for a mature company like Capital One, cost structure is often the most controllable and impactful lever, but for a startup, price might be more critical. This shows strategic thinking and avoids a one-size-fits-all answer.
State the formula: Breakeven customers = Fixed Costs / (Price - Variable Cost per Customer). Clarify that churn timing affects the expected lifetime and thus the effective price and variable cost over the customer's tenure.
Explain that price directly increases contribution margin, but its effect is linear and often constrained by market competition and willingness to pay. A 10% price increase may not be feasible without losing customers.
Discuss that churn timing affects the duration over which contribution margin is earned. Earlier churn reduces the total contribution per customer, effectively lowering the average margin and increasing breakeven count. However, churn timing is often a symptom of other factors like price or product value.
Argue that cost structure (fixed vs. variable costs) has the most fundamental impact. Reducing variable costs increases contribution margin directly, while reducing fixed costs lowers the numerator. Cost structure can be redesigned through automation, outsourcing, or scale, offering significant leverage.
Conclude that cost structure most affects breakeven customer count because it determines both the fixed costs and the contribution margin, and it is often more controllable than price or churn in the long run. Provide a numerical example to illustrate.
