THE NUMBERS, EXPLAINED

How to use this calculator.

Measured usage audit only. Mixture cost is a supplied weighted cost, not a formulation recommendation.

Start with your inputs

Enter prepared bowl masses by service (g), applied masses by service (g), discarded masses by service (g), mixture cost (currency/g). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.

InputExample value
Prepared bowl masses by service (g)100,120
Applied masses by service (g)80,90
Discarded masses by service (g)15,25
Mixture cost (currency/g)0.1

A worked example

With the example inputs above, recorded discard cost (currency) is 4. Change the inputs to explore your own scenario.

How this is calculated

Recorded discard cost (currency)

Multiply discarded mass by mixture cost.

Discard share of prepared mixture (%)

Divide measured discard by prepared mass.

Unreconciled mixture by service (g)

Subtract application and discard from prepared bowls.

Assumptions and limits

Measured usage audit only. Mixture cost is a supplied weighted cost, not a formulation recommendation.

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?

Recorded discard cost (currency); Discard share of prepared mixture (%); Unreconciled mixture by service (g). 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: Measured usage audit only. Mixture cost is a supplied weighted cost, not a formulation recommendation.
