Worked case math

Is a subscription service profitable?

Original fictional practice example by the ClawPad editorial team. Published . These are assumed figures, not customer data or a recorded ClawPad answer.

State the assumptions before calculating

Assume 1,000 paying subscribers for a full month, each paying US$30/month. Variable cost is US$18 per subscriber per month. All remaining operating costs total US$8,000/month and stay fixed in both scenarios. Ignore interest and taxes. The question is monthly operating profit under this simplified model.

  1. Calculate revenue and contribution

    Revenue = 1,000 × US$30 = US$30,000/month. Variable cost = 1,000 × US$18 = US$18,000/month. Contribution, the amount left to cover fixed costs and profit, is US$12,000/month. Cross-check it as 1,000 × (US$30 − US$18).

  2. Find and correct the deliberate error

    A draft says “US$12,000 − US$8,000 = US$6,000 profit per month.” That subtraction is wrong. The correct operating profit is US$4,000/month. Reverse the step to check it. US$4,000 + US$8,000 = US$12,000.

    Operating margin = US$4,000 ÷ US$30,000 × 100 = 13.3%, rounded to one decimal place. Divide by revenue, not by costs.

  3. Change one assumption and explain the sensitivity

    Reduce subscribers by 20% to 800 and hold price and costs per subscriber fixed. Revenue becomes US$24,000/month and variable cost US$14,400/month. Profit = 800 × (US$30 − US$18) − US$8,000 = US$1,600/month. The margin falls to 6.7%, rounded to one decimal place.

    Profit falls by US$2,400/month, or 60%, because the US$8,000/month fixed cost does not fall with subscriber count. A 20% demand change is not a 20% profit change.

What the arithmetic cannot establish

Both scenarios have positive operating profit under these assumptions. That alone does not justify expansion. Check whether customers will pay the price, whether they stay, and whether acquisition and support costs really fit this model. Correct sums cannot prove demand, establish the real costs or identify expenses you omitted.

This is a manual practice check. ClawPad does not automatically validate consulting case math. Its native arithmetic checks cover specific structured system-design capacity fields. The changed-constraint walkthrough explains those limits.

Case Interview FAQ

Frequently asked questions about consulting prep with ClawPad.

How ClawPad helps you crack case interviews and ace mental math under pressure.

How does ClawPad verify case math calculations?

ClawPad does not automatically verify consulting case math. It can present calculations step by step, but you must check the inputs, units and arithmetic yourself. Its on-device arithmetic validator is limited to specific structured system-design capacity fields; it is not a general case-math or finance calculator.

Does ClawPad cover standard MBB frameworks?

Yes. ClawPad structures cases into Profitability (Revenue & Cost drivers), Market Entry, M&A Synergies, Pricing Strategy, and Value Chain Optimization.

Can ClawPad help with behavioral Fit / PEI rounds?

Yes. ClawPad's grounded profile feature formats your authentic career experiences into structured STAR stories tailored for McKinsey Personal Experience Interview (PEI) and BCG Fit questions.

Is ClawPad useful for both management consulting and tech consulting?

Yes. The consulting domain pack adapts its depth depending on whether the prompt is strategic business transformation, financial turnaround, or technology modernization.
