unit cost
Unit cost is what it truly costs a business to make or deliver one single item, once every expense involved is added up and shared out fairly.
In plain English
Aunty Ngozi sells chinchin from a small stall near the market in Enugu, and one evening she is frowning at a notebook, muttering that she does not understand how she is working so hard and still not seeing much profit.
Her daughter, home from school, asks her a simple question. How much does it cost you to make just one bag of chinchin? Not the whole basin, just one bag. Aunty Ngozi cannot answer immediately, and that silence is the whole problem.
That is unit cost. It is the flour, the sugar, the oil, the gas for frying, the small nylon bag, and even a slice of her own time and the stall rent for the day, all added together and then divided by how many bags she actually produced. If everything for the day cost her ₦18,000 and she made 60 bags, each bag genuinely cost her ₦300 to produce, whether she remembers to think about it or not.
Businesses everywhere run on this same calm arithmetic. A bakery in Lagos pricing loaves of bread needs to know its unit cost before it can know if ₦900 a loaf is generous or is calmly bleeding it dry. A small manufacturing firm in Sheffield making phone cases works out the unit cost of plastic, machine time, and packaging before it dares set a wholesale price for retailers.
Even someone in Toronto sending money home to fund a family shop should care about this number, because a shop that does not know its unit cost cannot tell the difference between a good sales day and a day it simply moved a lot of stock while calmly losing money on each one.
Once you know unit cost, pricing stops being guesswork and starts being a decision you can defend.
A small poultry farm in Ibadan spends ₦450,000 in a month on feed, chicks, medication, and light labour, and produces 900 birds ready for sale. The unit cost per bird is ₦450,000 divided by 900, which comes to ₦500. If the farm sells each bird for ₦700, it knows with certainty that it is making ₦200 profit per bird, more than hoping so.
Questions people ask
Is unit cost the same as selling price?
No. Unit cost is what it costs you to produce or acquire one item. Selling price is what you charge the customer for it. The gap between the two is your profit margin, and that gap should always be a deliberate choice, not an accident.
What costs actually go into unit cost?
Everything tied to making that item exists in the first place. Raw materials, packaging, direct labour, and a fair share of overheads like rent, electricity, or machine wear all belong in the sum, which is then divided by the total units produced.
Why do many small Nigerian businesses get this wrong?
Because they often count only the obvious cash costs like ingredients or stock, and forget to spread in rent, transport, spoilage, or their own labour. This makes profit look bigger on paper than it truly is, until money starts disappearing mysteriously.
