Methods

Calculate(decimal, decimal, bool, decimal, bool, decimal?, decimal?, out IPensionContributionCalculationResult)

Calculates the appropriate employee and employer pension contributions based on the supplied employer and employee rates. Also supports the ability to supply a fixed employee contribution as an alternative to an employee percentage rate.

void Calculate(decimal pensionableSalary, decimal employerContribution, bool employerContributionIsFixedAmount, decimal employeeContribution, bool employeeContributionIsFixedAmount, decimal? avcForPeriod, decimal? salaryForMaternityPurposes, out IPensionContributionCalculationResult result)

Parameters

pensionableSalary decimal

Pensionable salary to be used for calculation.

employerContribution decimal

Employer contribution level, either expressed in percentage points (i.e., 5% = 5.0m) or as a fixed amount (i.e. £500.00), as indicated by employerContributionIsFixedAmount.

employerContributionIsFixedAmount bool

True if the employerContribution parameter should be treated as a fixed amount; false if it should be treated as a percentage.

employeeContribution decimal

Employee contribution level, either expressed in percentage points (i.e., 5% = 5.0m) or as a fixed amount (i.e. £500.00), as indicated by the following parameter.

employeeContributionIsFixedAmount bool

True if the employeeContribution parameter should be treated as a fixed amount; false if it should be treated as a percentage.

avcForPeriod decimal?

Any Additional Voluntary Contribution (AVC) on the part of the employee.

salaryForMaternityPurposes decimal?

Used to override the employer contribution when an individual is on maternity leave and should be paid employer contributions based on their contracted salary rather than their pensionable pay.

result IPensionContributionCalculationResult

An instance of a IPensionContributionCalculationResult implementation that contains the results of the calculation.

CalculateUnderSalaryExchange(decimal, decimal, bool, decimal, decimal, decimal, bool, decimal?, decimal?, out IPensionContributionCalculationResult)

Calculates the appropriate employee and employer pension contributions based on the supplied employer and employee rates, but under salary exchange arrangements. Here the output employee contribution will always be zero. Also supports the ability to supply a fixed employee contribution as an alternative to an employee percentage rate.

void CalculateUnderSalaryExchange(decimal pensionableSalary, decimal employerContribution, bool employerContributionIsFixedAmount, decimal employerNiSavings, decimal employerNiSavingsReinvestmentPercentage, decimal employeeSalaryExchanged, bool employeeSalaryExchangedIsFixedAmount, decimal? avcForPeriod, decimal? salaryForMaternityPurposes, out IPensionContributionCalculationResult result)
