The Benefit Calculator is intended as an educational tool only. Participants can use this tool to help develop personal retirement strategies or provide estimated financial information. This calculator allows participants to calculate an unofficial estimated projection of a pension benefit based on information entered. If any of the information entered differs from what pension fund records contain, the projection will not be accurate. A benefit calculation produced using the Benefit Calculator should not be relied on as confirmation of the accuracy of a final benefit calculation. The actual pension awarded from the pension fund must be calculated under the provisions of the applicable law in effect at the time of benefit.

The Benefit Calculator does not accommodate calculations of Tier 1 conversions from disability to retirement benefits, Tier 1 dependent benefits, or any Tier 2 benefits. The 'surviving spouse benefit for deferred pensions' does not calculate in the manner prescribed by Thornley v. Board of Trustees of River Forest Police Pension Fund and The Village of River Forest 2022 IL APP (1st) 210835, Opinion filed March 31, 2022, do not rely on this calculator for this particular type of benefit.
