Description
Return budget×needWeight/totalWeight.
Allocation models distribute resources, burdens or compensation using explicit weights and reference values. Arithmetic transparency can expose assumptions, but a proportional share or restored balance does not establish fairness, entitlement or responsibility.
Return budget×needWeight/totalWeight.
When to use this tool
Use Need Weighted Allocation One Share when you need one stated allocation, burden or compensation term.
How to use the tool and how it works
- Enter budget, needWeight, totalWeight. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read share. Use the output convention below.
Require nonnegative budget/needWeight and positive totalWeight at least needWeight. Return budget×needWeight/totalWeight.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| budget | Budget | Required. Finite number; minimum 0. |
| needWeight | Need Weight | Required. Finite number; minimum 0. |
| totalWeight | Total Weight | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| share | Dimensionless share on the numerator and denominator basis stated above. | Required. Finite number. |

}Limitations and assumptions
- Only one share is calculated. Need weights are supplied, not a verified needs assessment, fair allocation or entitlement determination.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Review the underlying needs, rights, valuation and distribution process. Consider the complete allocation and affected parties rather than inferring justice from one calculated share.
