Buea Infant Cereal Enterprise: Break-Even, a School Contract and a Price War
A young entrepreneur in Buea sets up a small unit producing a fortified millet-soy infant cereal in 500 g sachets. She takes a 3,000,000 FCFA equipment loan repayable in equal monthly instalments over 24 months at 12% per year, with monthly interest of 1% (an amortised loan, so the monthly payment exceeds 3,000,000 divided by 24). Other fixed costs are rent 50,000 FCFA, registration and licence 25,000 FCFA, electricity and water 35,000 FCFA, and one employee's wages 60,000 FCFA per month. Each 500 g sachet uses 700 FCFA of raw materials (millet, soy, sugar, vitamin-mineral premix), 120 FCFA of packaging, 30 FCFA of sealing labour and 50 FCFA of local transport - 900 FCFA in total. She sells to wholesalers at 1,500 FCFA per sachet and currently makes and sells 900 sachets a month. A school feeding programme offers a 12-month contract for 400 extra sachets a month at 1,250 FCFA each. Supplying it would require a second worker at 45,000 FCFA a month and rental of a semi-automatic sealer at 20,000 FCFA a month.
1. Calculate monthly fixed costs, break-even volume and current monthly profit. Show your working and state one key assumption.

Step 1: the loan payment (annuity formula) Payment = P x i / [1 - (1 + i)^-n], with P = 3,000,000, i = 0.01, n = 24. (1.01)^24 = 1.2697, so (1.01)^-24 = 0.7876 and the denominator is 0.2124. Payment = 30,000 / 0.2124 = about 141,200 FCFA per month. Note that simply dividing 3,000,000 by 24 gives 125,000 and ignores interest; using that figure would understate fixed costs by about 16,000 FCFA a month.
Step 2: fixed costs 141,200 + 50,000 + 25,000 + 35,000 + 60,000 = 311,200 FCFA per month.
Step 3: contribution per sachet 1,500 - 900 = 600 FCFA.
Step 4: break-even 311,200 / 600 = 518.7, so 519 sachets per month. At 900 sachets she has a margin of safety of (900 - 519)/900 = 42%.
Step 5: current profit 900 x 600 - 311,200 = 540,000 - 311,200 = 228,800 FCFA per month.
Assumption: all 900 sachets produced are sold within the month, with no breakage, expiry write-off or uncollected receivables; and no tax or depreciation is included. Fixed costs are 42% of revenue at current volume, which means operating leverage is high - a fall in volume hurts profit quickly, and an increase in volume rewards her strongly.
2. Advise her on whether to accept the school feeding contract. Support the advice with numbers and identify two non-financial factors that matter.

Use incremental analysis only - the existing 900 sachets are unaffected by the decision, so their contribution is irrelevant to it; only new costs and new revenue count.
- Incremental revenue: 400 x 1,250 = 500,000 FCFA
- Incremental variable cost: 400 x 900 = 360,000 FCFA
- Incremental contribution: 400 x 350 = 140,000 FCFA
- Incremental fixed cost: 45,000 + 20,000 = 65,000 FCFA
- Net monthly gain: 140,000 - 65,000 = 75,000 FCFA
Profit with the contract: 900 x 600 + 400 x 350 - (311,200 + 65,000) = 540,000 + 140,000 - 376,200 = 303,800 FCFA, against 228,800 without it.
Decision rule: the contract price of 1,250 is above variable cost of 900, so each sachet contributes something; and the total contribution covers the extra fixed costs with a surplus. On purely financial grounds, accept.
Two non-financial factors
- Cash flow and payment terms. Public programmes are often slow payers. If payment takes 60 days, she must finance about 1,000,000 FCFA of receivables while still paying wages and raw materials. A profitable contract can bankrupt a small firm through working capital. She should negotiate payment within 30 days or a partial advance.
- Dependence and capacity. The contract is 400 of 1,300 sachets - about 31% of volume - from one buyer, which gives that buyer leverage at renewal. Volume also rises 44% with the same owner supervising, so quality risk rises: premix weighing, seal integrity and hygiene must not slip. She should pilot one month's output, keep a written price-review clause, and set a floor below which she will not go at renewal.
3. A competitor imports a similar cereal and sells to wholesalers at 1,100 FCFA per 500 g. How should she respond, and what evidence should she gather before changing her price or her product?
Read the worked answer
Do not simply match the price. At 1,100 FCFA her contribution would be 1,100 - 900 = 200 FCFA per sachet, and break-even would rise to 311,200 / 200 = 1,556 sachets a month - 73% above her current volume. She would also be fighting an importer with scale economies, and a price cut is very hard to reverse.
Better responses
- Segment. Serve buyers who value fortification and trust: the school programme, health centres, and mothers advised by health workers. The import competes on price; she can compete on a verifiable nutrient content and local provenance.
- Change the unit, not the unit price. A 250 g sachet costing about 470 FCFA in variable costs (350 raw materials, 80 packaging, 15 labour, 25 transport) and selling at 800 FCFA gives a contribution of 330 FCFA, which is 1,320 FCFA per kg against her current 1,200 per kg. The absolute price falls, which suits cash-constrained households, while the margin per kilogram rises.
- Build trust signals that an importer cannot easily copy: a batch number and date, preparation instructions in English and French, a laboratory certificate of fortification, and market demonstrations with tasting.
Evidence to gather before acting
- Sensory and acceptance testing. A blind hedonic test and a preference test against the competitor with 60-100 mothers, plus a two-week home-use test measuring repeat purchase - not just liking.
- Willingness to pay. A simple bidding game or price-ladder exercise, run in two or three markets, rather than guessing.
- Costing of any reformulation. A full variable-cost build-up for a smaller sachet and for any recipe change, so that the floor price is defined as variable cost plus a target contribution, and no product is ever sold below full cost in the core business.
- Competitive fact-check. Have the competitor's product tested for vitamin and mineral content; imported cereals are sometimes under-fortified, and a verifiable comparison is a marketing asset.
Conclusion: hold the 1,500 FCFA price for the core line, defend it with evidence of value, and compete for the low-cash segment through a smaller pack rather than a price cut.
