Baking is the clearest case of the batch problem: you buy by the bag, bake by the tray, and sell by the slice.
Almost everything you buy is used across several bakes. A 10 kg bag of flour is not a cost you can attach to one tray of muffins — it is a cost spread across every tray it eventually produces.
The practical way through this is not to track grams. It is to record what a batch cost you and how many it produced, at the moment you bake it, while you still remember. Estimating that a bake used about a third of a R180 bag is close enough to be useful and quick enough that you will actually do it.
A record that is roughly right and exists beats a precise one you abandon in week three.
Your cost per item depends on how many sellable items came out — and for baking that number moves. The recipe says 12 muffins. You get 11 because one stuck. You cut 9 slices from a cake one week and 10 the next.
Record what you actually got, not what the recipe promised. If a bake goes wrong and you salvage 8 of 12, the cost of that batch spreads across 8. It should push the cost per item up, because it really did cost you that.
Over a few months this is also how you find out which of your products fails often enough to be worth reworking or dropping.
Somebody orders a decorated cake for R450. It feels like a good order. Here is the batch:
| What it cost | Amount |
|---|---|
| Flour, eggs, butter, sugar | R95 |
| Icing, colouring, decorations | R120 |
| Board and box | R55 |
| Total | R270 |
The batch produced one sellable item, so the cost per item is R270. At R450 the cake leaves R180.
Now the honest question. That cake took you five hours between baking, cooling and decorating. R180 for five hours is R36 an hour, before the electricity. Compare it with a batch of five banana breads that costs R60, sells for R125, and takes ninety minutes.
Decorated cake: R36 an hour. Banana bread: about R43 an hour, and far less risk of a decorating disaster. Neither number is available to you until you write the batches down.
This is not an argument against celebration cakes. It is the information that lets you price them properly instead of discovering years later that your most impressive product was your worst paid.
Bakers produce in advance for a market or a weekend. When you spend R400 on Thursday for a Saturday market, Thursday looks terrible and Saturday looks wonderful. Neither is true.
What you did on Thursday was turn cash into stock. The cost belongs to the loaves on the day each one sells. Handle it that way and your weeks stop swinging wildly for no real reason.
Estimate the share each batch used rather than weighing everything. If a R180 bag makes about six bakes, count roughly R30 per bake. An estimate you record every time is worth more than a precise figure you stop keeping.
Divide the batch cost by the number you can actually sell. If you baked 12 and salvaged 8, the cost spreads over 8 and your cost per item rises. That is accurate: the waste really did cost you money.
Work out the profit first, then divide by the hours it took. That gives you a real hourly rate to judge. Whether to raise the price is your decision, but make it knowing the number rather than guessing.
No. Buying ingredients converts cash into stock; it is not a loss. The cost counts against profit as each item sells, which stops your weeks swinging between fake disasters and fake windfalls.
