| Input | Example value |
|---|---|
| Starting deli product mass (g) | 5000 |
| Trim and unusable loss (g) | 500 |
| Target portion mass (g) | 150 |
| Purchase cost of starting product (currency) | 45 |
A worked example
With the example inputs above, sellable whole portions is 30. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Sellable whole portions | 30 |
| Unsliced remainder (g) | 0 |
| Purchase cost per whole portion (currency) | 1.5 |
How this is calculated
Sellable whole portions
Divide trimmed yield by portion mass and round down.
Unsliced remainder (g)
Deduct full portions from trimmed product.
Purchase cost per whole portion (currency)
Allocate all purchase cost to complete saleable portions.
