Description

Return one supplied option cost contribution under an explicit nonnegative weight.

A policy scenario makes eligibility bases, rates, thresholds, periods, and costs explicit. A calculated share or balance follows those assumptions. It does not select the governing policy or establish what caused an observed program outcome.

Return one supplied option cost contribution under an explicit nonnegative weight.

When to use this tool

Use it for policy option cost weight when the required inputs and conventions are already available.

How to use the tool and how it works

  1. Enter cost, weight. Use the stated units and boundary conventions.
  2. Run the calculation. Correct any input error before interpreting a result.
  3. Read weightedCost. Inspect any known, defined, inclusion, or boundary flags before interpreting numeric values.

Require nonnegative weight and return weightedCost=cost*weight.1

Limitations and assumptions

  • Cost may be signed and weight need not be a probability or sum to one with other weights. This is one supplied weighted term, not a complete option appraisal or a derived preference weight.
  • The field tables describe structural bounds; the mechanics also state cross-field requirements. Malformed input shapes, disallowed keys, and invalid domains cause input errors. Results must remain finite and within the declared output contract. A successful false flag or zero placeholder is distinct from an error.
  • Numeric arithmetic uses binary floating point. Exact comparisons have no hidden tolerance or decimal rounding; negative zero is exported as zero. Decimal-text integer operations retain the exactness specifically stated above.

Alternative or Complementary methods

For policy option cost weight, check the source records and the supplied rule before comparing the result with another method. Consult the applicable authoritative rule when deciding eligibility, legal timing, fees, or obligations.
