How much will your pension be?
Benefit Estimator can help members project their monthly amount
By Michael Pramik, Ohio Public Employees Retirement System
Dec. 4, 2025 – OPERS offers members a Benefit Estimator, which can help those in the Traditional Pension Plan see what their pension benefit might be when they retire.
OPERS calculates defined benefit pensions according to a formula that considers service credit, the age at which you retire and your final average salary, as well as your retirement group.
Traditional Pension Plan members can use the Benefit Estimator, available through their online account, to project pensions under different scenarios.

Keep up the good work.
Please consider updating the online benefit calculator so members can edit the estimated Final Average Salary used for the benefit estimate. I was active in OPERS through 2016, but have been in Ohio Police & Fire since. The online calculator allows me to enter any amount of service credit from OP&F to transfer and be added to my OPERS service time. However, it does not allow any adjustment to the FAS. Because of this, the calculator provides a grossly inaccurate estimate. I have reached out to several reps at OPERS who all tell me there is no way for OPERS to estimate my future retirement benefit. A simple change in that single field of the calculator would seem to fix this.
