Totalization Contribution Comparison
Compare social contributions under caller-supplied totalization agreement assumptions.
Description
A totalization scenario compares contributions under two supplied rates and a chosen coverage country.
A totalization scenario compares contributions under two supplied rates and a chosen coverage country. The savings output is relative to the other contribution scenario.1
Compare social contributions under caller-supplied totalization agreement assumptions.
When to use Totalization Contribution Comparison
Use this tool to compare social contributions under caller-supplied totalization agreement assumptions.
Choose the specific arithmetic or checklist scenario and establish its input amounts, dates, rates and criteria from the applicable records. Keep currencies, periods and jurisdictions consistent; review the tool-specific assumptions before interpreting the result.
How to use Totalization Contribution Comparison and understand its results
- Choose the specific arithmetic or checklist scenario and establish its input amounts, dates, rates and criteria from the applicable records. Keep currencies, periods and jurisdictions consistent; review the tool-specific assumptions before interpreting the result.
- Enter coveredEarnings, homeCountryRatePercent, hostCountryRatePercent, applicableSystem using the field table and calculation rules, then run the tool.
- Read homeContribution, hostContribution, applicableContribution, savingsVersusOther. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| coveredEarnings | Covered earnings | number; minimum: 0 | Required |
| homeCountryRatePercent | Home-country contribution rate (%) | number; minimum: 0 | Required |
| hostCountryRatePercent | Host-country contribution rate (%) | number; minimum: 0 | Required |
| applicableSystem | Applicable system | string; one of "home", "host" | Required |
Enter nonnegative earnings and rates and select home or host coverage. Return both modeled contributions, the selected contribution and signed savings.
home=earnings×homeRate/100; host=earnings×hostRate/100; savings=other−applicable Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| homeContribution | Home-country contribution | number; minimum: 0 |
| hostContribution | Host-country contribution | number; minimum: 0 |
| applicableContribution | Applicable contribution | number; minimum: 0 |
| savingsVersusOther | Savings versus other system | number |

}Limitations and assumptions
Coverage is an input rather than an agreement determination. Benefit entitlements, wage caps, exemptions and contribution certificates are not checked.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
