Contribution Rates

How rates are determined

The State Actuary evaluates the plans each year. In odd-numbered years, the data is used to recommend contribution rate adjustments (if any) to the Pension Funding Council. Several factors go into the rate calculations, including the financial and demographic experience of the plans and the cost of any benefit increases.
