Context and business challenge

A profitable specialist retailer is considering opening a second outlet. The proposed location appears attractive, but management has not yet quantified all ongoing costs, initial funding needs or the possibility that existing customers will simply switch stores. Market interest alone is not proof of financial feasibility.

Transparency:This fictional case is provided for education only. It does not represent an actual company, client project, achieved result or consulting engagement.

Initial data and assumptions

The illustrative assumptions are €48,000 in additional annual fixed costs, €12,000 in initial working capital, €180,000 in annual incremental sales and a 35% contribution margin. They must not be interpreted as actual results or a verified investment appraisal.

How to investigate the causes

Estimate truly incremental demand and evaluate local competition before forecasting sales. Validate lease costs, staffing, logistics, inventory needs and seasonality. Build conservative, base and favourable scenarios, taking account of the initial investment, working capital, cash-flow timing and possible diversion of customers from the original shop.

Quantitative analysis

In the base case, €180,000 of new sales at a 35% contribution margin yields €63,000, leaving €15,000 after €48,000 of extra fixed costs. The illustrative initial funding requirement is €60,000. Dividing €60,000 by €15,000 produces four years, but this is not a valid discounted cash payback calculation: it omits taxes, investment replacement, working-capital movements and cash-flow timing. Simplified annual break-even sales are €48,000 ÷ 35%, or approximately €137,143.

Proposed action plan

Test demand locally before taking on long-term commitments. Negotiate contractual conditions, detail the capital budget and analyse lower-sales and lower-margin scenarios. Establish explicit thresholds to approve, postpone or reject the investment and check whether the existing business can finance the additional cash requirement.

Monitoring indicators

Monitor incremental revenue, contribution margin, the break-even point, monthly cash flow, funding requirements and sales cannibalised from the original shop. Compare actual results with the assumptions that supported the original decision.

Risks and limits of the analysis

If customers migrate from the first shop, net incremental sales will be lower than assumed. The model must also account for seasonal demand, VAT and other taxes, depreciation, financing costs and the cost of capital. A positive simplified operating contribution is not sufficient evidence to open a second location.

Explore Risks and limits of the analysisCase takeaway: opening the new shop is not an automatic decision. Management needs additional evidence and alternative scenarios, including digital channels and partnerships.
