Formula Used
The Tier 2 Regular pension estimate uses 1.6667% of capped Final Rate of Earnings for each of the first 15 service years. It uses 2% for each service year after 15 years. The total multiplier is limited to 75% of capped Final Rate of Earnings.
Base monthly pension = capped monthly FRE × formula multiplier.
Estimated monthly pension = base monthly pension × (1 − early reduction rate).
For retirement before age 67, the tool applies a 0.5% reduction for each applicable month. For 30 to under 35 regular service years, it uses the lesser reduction test. Annual increase projections use the lower of 3% or one half of the CPI estimate. The projection is simple, not compounded.

IMRF Tier 2 Pension Planning Guide
An IMRF Tier 2 pension estimate helps a member review retirement income before filing official paperwork. The calculator uses service credit, retirement age, final earnings, and the wage cap. It gives a practical monthly estimate. It also shows how early retirement rules may reduce the amount.
Why Tier 2 needs careful inputs
Tier 2 rules depend on age and service. A member normally needs at least ten years of service and age sixty two to start a regular pension. Age sixty seven is the full retirement age. Service of thirty five years can remove the early reduction at age sixty two or later. Because small month differences matter, the form separates years and months.
Final rate of earnings
The final rate of earnings is a key salary figure. This tool lets you enter it as monthly or annual pay. It then applies the wage cap. The official system may compare different earnings methods when calculating the final benefit. This calculator keeps the process transparent by showing the capped amount used in the formula.
Service multiplier logic
The first fifteen years receive one and two thirds percent for each year. Service after fifteen years receives two percent for each year. The result cannot exceed seventy five percent of the final rate of earnings. The calculator applies that ceiling before showing the base pension.
Early retirement reduction
If retirement starts before age sixty seven, a reduction may apply. The standard reduction is one half percent for each month under age sixty seven. For members with at least thirty years but less than thirty five years, the smaller of two reductions is used. The comparison uses months under age sixty seven and months short of thirty five years.
Planning with reports
The result table can be exported as CSV for spreadsheets. It can also be saved as a simple PDF report. Use the projection inputs to test annual increases. The increase estimate is simple and non compounded. It is meant for planning only. Always request an official estimate before making a retirement decision.
Keep copies of each run. Compare ages, service dates, and wage cap assumptions. Save notes beside your export for later review and benefit talks.
FAQs
1. What is an IMRF Tier 2 pension?
It is a retirement benefit for covered members who entered Tier 2 rules. This calculator estimates the Regular Plan pension using age, service, and capped earnings.
2. Is this an official IMRF estimate?
No. It is only a planning tool. Use it to compare scenarios. Request an official estimate before choosing a retirement date or filing paperwork.
3. What is Final Rate of Earnings?
Final Rate of Earnings is the salary amount used in the pension formula. This tool accepts either monthly or annual earnings and applies the selected wage cap.
4. Why is there a wage cap input?
Tier 2 benefits apply a wage cap. The cap can change. The field lets you use the current cap, a future estimate, or a custom planning value.
5. How does early retirement reduction work?
The tool checks age and service. If a reduction applies, it estimates one half percent per applicable month under the Tier 2 reduction rule.
6. Can sick credit meet eligibility rules?
This calculator separates converted sick credit from regular service. It adds sick credit to formula service but not to the basic eligibility service test.
7. What does the annual increase projection show?
It shows a simple planning estimate using the lower of 3% or one half of CPI. It is not compounded and is not guaranteed.
8. Why add CSV and PDF downloads?
CSV helps with spreadsheet review. PDF gives a simple printable record. Both downloads use the same values entered in the calculator form.
