Description
Pro rate a supplied premium and multiplier; this does not determine policy coverage.
Property calculations depend on the chosen area, time, rate, and money bases. A ratio, proration, or balance is meaningful only when its inputs describe the same transaction and period. Contract interpretation and the selection of applicable rules remain separate tasks.
Pro rate a supplied premium and multiplier; this does not determine policy coverage.
When to use this tool
Use it for property insurance premium vacancy share when the required inputs and conventions are already available.
How to use the tool and how it works
- Enter annualPremium, vacantDays, yearDays, vacancyMultiplier. Use the stated units and boundary conventions.
- Run the calculation. Correct any input error before interpreting a result.
- Read baseAllocated, adjustedAllocated, increment. Inspect any known, defined, inclusion, or boundary flags before interpreting numeric values.
Prorate annualPremium by vacantDays/yearDays, multiply by vacancyMultiplier, and return adjusted allocation and the increment over the base allocation.1

|---|---|---|
| annualPremium | Annual Premium | Required. Finite number; minimum 0. |
| vacantDays | Vacant Days | Required. Finite number; minimum 0. |
| yearDays | Year Days | Required. Finite number; strictly above 0. |
| vacancyMultiplier | Vacancy Multiplier | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| baseAllocated | Base Allocated | Required. Finite number. |
| adjustedAllocated | Adjusted Allocated | Required. Finite number. |
| increment | Increment | Required. Finite number. |

}Limitations and assumptions
- The multiplier is supplied, can be below one, and does not establish policy coverage or an insurer's actual surcharge. Days, currency, and premium period must be consistent.
- 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 property insurance premium vacancy share, 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.
