Description
Calculate contributor-to-beneficiary and inverse count ratios.
Demographic economic terms depend on age-window boundaries, population scope, household equivalence units and supplied fiscal assumptions. A worker-share change is not an estimated demographic dividend, and endpoint survivors times duration differ from integrated life-table person-years. Local pension or subsidy calculations do not determine actual eligibility or entitlement.
Calculate contributor-to-beneficiary and inverse count ratios.
When to use this tool
Use Pension Contributor Beneficiary Ratio when you already have contributors, beneficiaries and need to calculate contributor-to-beneficiary and inverse count ratios.
How to use the tool and how it works
- Enter contributors, beneficiaries. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read contributorsPerBeneficiary, beneficiariesPerContributor. Use the output convention below.
Require both counts positive safe integers; return contributors/beneficiaries and beneficiaries/contributors.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| contributors | Contributors | Required. Safe integer; minimum 1. |
| beneficiaries | Beneficiaries | Required. Safe integer; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| contributorsPerBeneficiary | Contributors Per Beneficiary | Required. Finite number. |
| beneficiariesPerContributor | Beneficiaries Per Contributor | Required. Finite number. |

}Limitations and assumptions
- Zero groups are rejected. No pension system sustainability, age structure, coverage, contribution amounts or policy outcome is estimated.
- 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
Use complete population, cohort, labor and fiscal records with the chosen equivalence and exposure definitions. Review applicable benefit rules and estimate the appropriate model for policy analysis; one supplied allocation or accounting ratio does not establish behavior or economic effects.
