AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
The cost of one loaf is the full cost of a batch (ingredients, oven energy, labour, packaging and a share of overheads) divided by the loaves you actually sell, not the loaves you bake. Wastage and retailer returns raise the cost of every good loaf, so they belong in the sum. Re-cost the batch whenever flour, sugar or gas prices change.
Most small bakeries in Nigeria price bread by looking at what the next bakery charges, then adjusting when flour goes up. That works until a run of price rises quietly turns a profitable loaf into a loss-maker. Costing per loaf fixes this: you build the cost of one batch from the bottom up, divide by the loaves that leave the bakery as sales, and compare that number with your selling price every time an input price moves.
What goes into the cost of one loaf
A loaf carries five kinds of cost. Keep them separate, because they move for different reasons.
- Ingredients: flour, sugar, fat or margarine, yeast, salt, improver or preservative, water, and any milk, butter or flavouring for premium lines.
- Energy: gas, diesel or firewood for the oven, plus fuel or electricity for the mixer, moulder and lighting.
- Labour: mixers, bakers, packers and the people who load the van, costed per batch rather than per month.
- Packaging: nylon or wrapping film, labels, tape, trays.
- Overheads: rent, equipment repairs, regulatory renewals, delivery, phone and data, spread across the batches you bake in a month.
The international inventory standard, IAS 2, is a useful guide here even if you never produce audited accounts: the cost of goods includes the purchase price plus transport and handling to get materials to you, less trade discounts. A bag of flour delivered to your door costs the price plus the delivery, not the price alone.
Step 1: cost one batch
Pick your standard batch, usually built around one bag of flour, and write down what goes into it. The figures below are an example only. They are not market quotes; use your own receipts.
| Item (example batch, one 50kg bag of flour) | Example cost (₦) |
|---|---|
| Flour, 50kg bag, delivered | 80,000 |
| Sugar, 5kg | 9,000 |
| Margarine or fat, 2.5kg | 7,500 |
| Yeast, 0.5kg | 4,000 |
| Salt, improver and preservative | 2,500 |
| Water | 500 |
| Ingredients total | 103,500 |
| Oven gas (one 12.5kg refill lasts five batches; ₦18,750 refill ÷ 5) | 3,750 |
| Generator diesel for mixer and lights | 4,000 |
| Labour (four workers at ₦5,000 a day, two batches a day) | 10,000 |
| Packaging (₦25 a loaf × 154 saleable loaves) | 3,850 |
| Overheads share (₦300,000 a month ÷ 50 batches) | 6,000 |
| Total batch cost | 131,100 |
Energy is where bakers most often guess. Measure it: note the date you connect a new gas cylinder or fill the generator, count the batches until it runs out, and divide. Do the same for labour. If your four workers also clean, receive deliveries and do a third, smaller batch on Saturdays, cost the labour over the actual number of batches in the week.
Step 2: count wastage and returns properly
Say the example batch is moulded into 160 loaves. Six come out burnt, underweight or misshapen and cannot be sold at full price. That leaves 154 saleable loaves, and the batch cost per saleable loaf is ₦131,100 ÷ 154 = about ₦851.
Then the van comes back. If retailers return eight loaves that are now stale and cannot be resold, only 146 loaves earned money. The cost per loaf sold is ₦131,100 ÷ 146 = about ₦898. The difference of roughly ₦47 a loaf is the price of wastage and returns. Ignore it, and you will think you are making more than you are.
- Keep a daily production sheet: bags used, loaves moulded, loaves rejected and why.
- Keep a returns sheet per retailer and per route.
- Work out your wastage rate each week: rejected plus returned, divided by loaves moulded.
- Use the last four weeks' average in your costing, not your best day.
Step 3: set the price and test it
Once you know the cost per loaf sold, pricing becomes arithmetic. Continuing the example, if you sell to retailers at ₦1,000 a loaf, the margin is ₦1,000 − ₦898 = ₦102 a loaf, or ₦14,900 on the batch (146 × ₦1,000 = ₦146,000, less ₦131,100). That is about 10% of the selling price, which leaves little room for a bad week.
Three tests are worth running before you change your price list:
- Flour test: if the bag rises by ₦5,000, the batch rises by ₦5,000 and the cost per loaf sold rises by about ₦34 (₦5,000 ÷ 146).
- Size test: if you keep the price but reduce dough weight, recalculate yield. More loaves per bag lowers the cost per loaf, but customers notice weight, and loaf weight is part of what you are selling.
- Returns test: if a retailer regularly returns more than the route average, the loaves you send there cost more than the loaves sent elsewhere.
How often to re-cost, and what to keep
Re-cost the standard batch whenever a main input changes price, and at least once a month even if nothing seems to have changed. Keep the receipts and the production sheets: a small company with turnover up to ₦100 million and fixed assets up to ₦250 million is exempt from company income tax under the 2025 reforms, but it still needs records to show where it stands. Unit costing also tells you which product lines pay their way. Many bakeries find that small loaves, which use almost the same labour and packaging as big ones, carry the thinnest margin.

Where Pryme fits
A Pryme Business Account comes with a Finance agent that can prepare the daily costing from the purchases and sales recorded in the account; a person reviews it, and nothing is paid without approval. If you sell to shops on credit, read our guide to selling bread on credit to retailers.
Questions people ask
How do I calculate the cost of one loaf of bread?
Add up the full cost of one batch, including ingredients, gas or diesel, labour, packaging and a share of monthly overheads, then divide by the number of loaves you actually sell from that batch after rejects and returns.
How many loaves can one bag of flour produce in Nigeria?
It depends on your recipe and the dough weight per loaf. Measure your own yield by counting loaves moulded from each bag over several batches, and use the average.
Should I include my own salary in the cost of bread?
Yes. If you work in the bakery every day, cost your time as labour. Otherwise the business looks profitable only because you are working for free.
How often should a bakery change its bread price?
Re-cost whenever flour, sugar, fat or energy prices move, and at least monthly. Change the selling price when the margin per loaf sold falls below the level you need to cover bad weeks.
