← Capital One Interview Insights
Straightforward setup question but I second-guessed myself on whether VC applied to gross revenue or net.
Start by clearly stating the formula for daily profit: Profit = Revenue - Variable Costs - Fixed Costs. Then compute each component step-by-step, showing your calculations and assumptions, and finally arrive at the baseline daily profit.
Pro tip: After calculating the baseline, briefly mention that this is a simplified model and that in a real business context, you would consider factors like seasonality, customer acquisition costs, and capacity constraints. This shows you think beyond the immediate numbers.
List the provided numbers: 20 tables per day, $30 average revenue per table, variable costs at 40% of revenue, and $100 fixed costs daily.
Multiply the number of tables by the average revenue per table: 20 * $30 = $600.
Compute 40% of total revenue: 0.40 * $600 = $240.
Subtract variable costs and fixed costs from revenue: $600 - $240 - $100 = $260.
Clearly state the baseline daily profit is $260, and note any assumptions such as constant demand and no other costs.

First, clarify the baseline daily profit and the average check per table under normal conditions. Then, model the new profit equation with the 40% commission and solve for the average check that equates the new profit to the baseline. Present the calculation clearly and discuss any assumptions.
Pro tip: Always state your assumptions explicitly (e.g., baseline average check, number of tables, daily profit) and show the algebra step-by-step. This demonstrates rigor and helps the interviewer follow your logic.
Let baseline daily profit be P, average check per table be A, and number of tables be 20. So P = 20 * A (assuming no other costs).
With 40% commission, the platform takes 0.4 * check, so the restaurant keeps 0.6 * check per table. New profit = 20 * 0.6 * X, where X is the new average check.
Set 20 * 0.6 * X = 20 * A, which simplifies to 0.6X = A, so X = A / 0.6 = 1.6667 * A. Thus, the new average check must be about 66.7% higher than the baseline.
Explain that to maintain profit, the average check must increase by 66.7% when all tables use a coupon with 40% commission. Discuss feasibility and potential strategies.

First, clarify the baseline scenario and the assumptions about costs and commissions. Then compute the new daily profit by summing revenue from all tables and subtracting variable costs, fixed costs, and coupon commissions. Finally, decompose the profit change into volume, price (average check), and commission effects using a structured variance analysis.
Pro tip: When decomposing the profit change, use a sequential (step-by-step) approach to isolate each effect, and clearly state the order of decomposition to avoid double-counting. Also, explicitly state any assumptions about the commission rate and whether the average check increase applies to all tables or only coupon tables.
Establish the baseline daily profit, the original number of tables, and the original average check. Confirm the commission rate per coupon table and whether fixed and variable costs per table remain constant.
Compute total revenue as 25 tables * $36 average check. Subtract variable costs (25 * variable cost per table), fixed costs, and commission costs (10 * commission per coupon table) to get the new daily profit.
Calculate the profit impact of serving 25 tables instead of the baseline number, holding average check and commission structure constant. This isolates the effect of more tables.
Calculate the profit impact of the higher average check ($36 vs. baseline), holding the number of tables and commission structure constant. This isolates the effect of a higher average check.
Calculate the profit impact of commissions paid on the 10 coupon tables, holding all else constant. This isolates the cost of commissions.

First, restate the baseline and current profit figures from the previous scenario to confirm understanding. Then calculate the absolute and percentage change, and decompose the profit change into its key drivers (e.g., revenue, cost, volume, price) to identify the main contributor. Finally, clearly state whether profit is up or down, by how much, and name the primary driver.
Pro tip: Always quantify the impact of each driver and compare their relative contributions; this shows you can prioritize factors and communicate insights effectively to stakeholders.
Restate the baseline profit and the current profit from the previous scenario to ensure alignment and avoid misinterpretation.
Compute the absolute difference and percentage change in profit to determine if it is up or down and by how much.
Break down profit into components such as revenue (price × volume) and costs (fixed and variable) to analyze which factor changed most significantly.
Compare the magnitude of each driver's contribution to the total profit change and determine which one had the largest impact.
Concisely state the direction and size of the profit change, and clearly name the main driver, supporting with numbers.
