Lumia Skincare: Premium Range and Cannibalisation
Lumia is a mass-market skincare brand with 22% value share in facial cleansers, average retail price £6.50, and strong penetration among 18–34-year-olds. A national pharmacy chain offers Lumia 1.2 metres of additional shelf space, but only for a new premium 'botanical repair' range priced at £18–£22. The chain will delist the range after 12 months if it does not reach £1.1 million in retail sales. Lumia's internal panel suggests 35% of current Lumia cleanser buyers would consider trading up; of those, half would buy the premium range instead of their usual Lumia product rather than in addition. Gross margin is 42% on the mass line and 55% on the premium line. Launch costs are £450,000. The brand team is split: one group wants a standalone brand name to avoid diluting Lumia; another wants a Lumia-endorsed sub-brand to transfer trust. The CEO is worried about cannibalisation and retailer dependence.
1. Calculate the break-even level of cannibalisation for the £1.1 million target. State your assumptions and what the result means for the launch decision.
Read the worked answer
Premium gross margin at target = £1.1m × 55% = £605k. Launch cost = £450k. With no cannibalisation, year-one net = £155k. For a cannibalised £1 of premium sales, assume it displaces £1 of mass sales. Lost mass margin = 42p; retained premium margin = 55p; incremental margin = 13p. Let x be cannibalised premium sales. Net = 0.55 × (1.1m − x) + 0.13x − 0.45m = 0.155m − 0.42x. Break-even x = 155k / 0.42 = £369k, or 33.5% of the £1.1m target. If more than about £369k of premium sales are switched from Lumia, the launch loses money before overhead. This is conservative because a £20 premium unit displaces a £6.50 mass unit, not £20 of mass sales; on a unit basis the lost margin is £2.73 versus £11 premium margin. The panel's 35% consider and 50% substitute implies 17.5% of current buyers could switch, which is a warning, not a forecast.
2. Recommend a brand-architecture choice: standalone name or Lumia-endorsed sub-brand. Justify it using the cannibalisation and retailer constraints.

Recommend an endorsed sub-brand, for example 'Lumia Botanics', rather than a fully standalone name, provided the pack and claims are visibly distinct. The pharmacy chain is buying Lumia's existing trust and footfall; a standalone brand would need separate awareness spend that the £450k launch budget may not support; endorsement lowers trial risk. To limit dilution, use a clear price ladder, separate shelf blocking, limited discounting, and no mass-line lookalike packs. Keep the mass line's availability strong. A standalone brand would be better only if the premium range needs clinical credibility, a different buyer, or if Lumia's mass price image would cap the premium price. Set a governance rule: if cannibalisation exceeds the £369k break-even or if switchers exceed 20% of buyers, slow distribution or adjust the range.
3. What metrics and contingency plans should Lumia put in place for the 12-month retailer deadline?
Read the worked answer
Track weekly retail sales against the £1.1m run-rate, repeat purchase, source of business (new buyer versus Lumia switcher), cannibalisation of the mass line, gross margin after trade spend, and shelf compliance. Use panel data plus loyalty-card data if available. Contingency: at week 8, if run-rate is below 70% of target, test a smaller pack or £18 entry price, add pharmacy sampling, or renegotiate the 12-month delist clause. If cannibalisation is above break-even, reduce promotion depth and separate the shelf further. Do not wait 12 months to learn.
