THE NUMBERS, EXPLAINED
How to use this calculator.
Member entitlement uses agreed contribution points, not a biological yield model. Compost amount is measured after processing.
Start with your inputs
Enter deposited material by member (kg), labour credits by member, agreed points per kg input, agreed points per labour credit, finished compost to share (l). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Deposited material by member (kg) | 10,20 |
| Labour credits by member | 2,1 |
| Agreed points per kg input | 1 |
| Agreed points per labour credit | 10 |
| Finished compost to share (L) | 90 |
A worked example
With the example inputs above, member contribution points is 30, 30. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Member contribution points | 30, 30 |
| Member compost entitlement (L) | 45, 45 |
How this is calculated
Member contribution points
Add material points and labour points for each member.
Member compost entitlement (L)
Normalize member points to measured finished compost.
Symbols and units
- a
- Deposited material by member (kg)
- b
- Labour credits by member
- c
- Agreed points per kg input
- d
- Agreed points per labour credit
- e
- Finished compost to share (L)
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
Member entitlement uses agreed contribution points, not a biological yield model. Compost amount is measured after processing.
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?
Member contribution points; Member compost entitlement (L). 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: Member entitlement uses agreed contribution points, not a biological yield model. Compost amount is measured after processing.
