Inputs and definitions
Choose the period first. Count sales excluding tax collected for a tax authority. Match consumed ingredients and packaging to that period rather than treating every inventory purchase as current consumption. Decide whether owner labor is included and state that choice beside the result.
| Input | Unit / meaning | SAMPLE DATA |
|---|---|---|
| Sales excluding collected tax | USD | 3200 |
| Ingredients consumed | USD | 800 |
| Labor charged to this period | USD | 900 |
| Packaging consumed | USD | 160 |
| Period overhead | USD | 430 |
| Delivery and platform costs | USD | 110 |
Formula and worked example
Modeled operating surplus = net sales − ingredients − labor − packaging − overhead − fees
SAMPLE DATA — fictional inputs, not US market benchmarks. 3,200 − 800 − 900 − 160 − 430 − 110 = $800.
The fictional month has $3,200 net sales, $800 ingredients, $900 labor, $160 packaging, $430 overhead and $110 delivery/platform costs. The model returns $800. It is not a claim about typical bakery profit. Unentered financing costs, tax obligations or unpaid work can change the economic picture.
Apply the result to this task
Use the result to investigate a specific mismatch: prices too low for the product mix, waste above plan, finishing time greater than quoted, or overhead not covered by volume. Do not assume more sales will improve a product that loses money on every unit.
Validation, exclusions and limits
Negative results are deliberately allowed and mean the entered costs exceed entered sales. Blank fields require a decision; they are not silently replaced by zero. The break-even analysis page answers how many units cover fixed costs under a stated mix; the cake profit page reviews one completed job.
Use finite numbers and keep money precise until the displayed result. Costs and time cannot be negative; required quantities must be positive. Check that your package, recipe and order quantities use compatible units. Clear a field to see the input error rather than carrying an old result into a decision.

A markup multiplies cost by one plus the rate; a target margin divides cost by one minus the rate. They are not interchangeable.
