THE NUMBERS, EXPLAINED
How to use this calculator.
Observational mass loss only, with matched batches and no additions after initial weighing. Sellable yield assumes all cooled product is saleable.
Start with your inputs
Enter pre-bake batch masses (kg), cooled baked batch masses (kg). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Pre-bake batch masses (kg) | 10,20 |
| Cooled baked batch masses (kg) | 8,17 |
A worked example
With the example inputs above, bake loss by batch (%) is 20, 15. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Bake loss by batch (%) | 20, 15 |
| Total cooled yield (kg) | 25 |
| Weighted overall bake loss (%) | 16.666667 |
How this is calculated
Bake loss by batch (%)
Divide each batch mass decrease by pre-bake mass.
Total cooled yield (kg)
Sum all cooled batch masses.
Weighted overall bake loss (%)
Divide total mass decrease by total pre-bake mass.
Symbols and units
- a
- Pre-bake batch masses (kg)
- b
- Cooled baked batch masses (kg)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Observational mass loss only, with matched batches and no additions after initial weighing. Sellable yield assumes all cooled product is saleable.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Bake loss by batch (%); Total cooled yield (kg); Weighted overall bake loss (%). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Observational mass loss only, with matched batches and no additions after initial weighing. Sellable yield assumes all cooled product is saleable.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
