When you are within 3 years of retirement eligibility you can request two estimates of benefits in a 12-month period, which can provide you with your first eligible retirement date and what you will receive in retirement. You can also request other dates. You will need to submit a PERA Request form and request an Estimate of Benefits, which is the second option on the form. On that line, you can type/write for example: first eligible, a specific date, a certain percentage, a certain number of birthdays, etc. You can submit your request form by email, fax, in-person, upload to your RIO Self-Service account, or by mail and you'll receive an estimate within 60 business days. You can also receive an estimate by logging into your PERA RIO Self Service account and use the estimate of benefits calculator. A member's base monthly benefit is calculated using the following statutorily defined formula, not what you have contributed during your PERA career: Years of Service Credit x Pension Factor (s) x Final Average Salary = Gross Monthly Benefit.
