Benefits Calculator


This calculator will allow you to generate an estimate of your future retirement benefits, however, it does not replace the actual calculation of benefits when you retire. If you are planning to retire, you should request estimates from the Employees’ Retirement System (ERS).

The calculator is a client side javascript which works within your own web browser. No information is transmitted or stored anywhere.

Things to Consider

The calculator will not:

  • estimate your future retirement benefit using an “inflation factor”
  • add interest to the estimated contributions
  • estimate disability retirement benefits
  • use any information from your ERS records, just the information you provide
