Tier I Benefit Formula and Factors:
- The amount of your monthly benefit is "defined" by a formula which
takes into account your years of retirement service credit, your average
salary, your age, and your plan membership.
- The following formula applies to all members of Tier I (although
Plan B members will be subject to a modest reduction upon reaching the
full Social Security age):
||Retirement Service Credit
- Benefit Rate: Your years of service and your age will determine your
- Percent of Entitlement: Under the Tier I formula, you are entitled
to a specific percentage of your average salary. This percentage is
determined by multiplying your benefit rate by your years of credited
Retirement Service Credit:
- Retirement Service Credit Includes:
- All periods of service for which you have paid retirement
- Periods of creditable workers' compensation.
- Your service credit will be extended if you receive a payout for
any unused vacation days upon your retirement/separation from state
- Properly documented voluntary leave taken after 6/9/94 counts as
free retirement service credit.
- Any periods of purchased service credit will be included in your
total retirement service credit.
- Retirement Service Credit Excludes:
- Any periods for which you have not paid retirement contributions, this
- Un-purchased leaves of absence without pay;
- Periods for which you exclusively received non-creditable workers'
- Periods of state service for which you did not participate in Tier
- Periods for which you participated in Tier I but later refunded
your retirement contributions.
- If you have had part-time service, you should know that:
- your part-time service will be treated as full-time service when
determining your eligibility to retire and your benefit rate (as
determined by the Tier I rate chart).
- your retirement income will be calculated to produce a benefit
which reflects the portion of a full-time schedule you worked throughout
your state employment.
- Lets assume a retiree worked part-time at 50% of a full-time schedule
for 10 years
- For determining eligibility and your benefit rate from the chart, we
will use 10 years.
- However, when calculating your percent of entitlement, we will use
5 years (the full-time equivalent of working 50% of full-time for 10
- Your average salary is the average of your 3 highest paid years of
- Any 1 period of 12 consecutive months equals 1 year.
- Although for the majority of retirees the average salary is the
average of the last 36 months of employment, when calculating your
average salary the 3 years don't have to be consecutive years or
- A small percentage of retirees may find themselves subject to the
130% Cap provision:
- When calculating your average salary, no one year's earnings can be
greater than 130% of the average of the two preceding years. this
excludes mandatory overtime earnings. Effective 7/1/2014, no one
year's earnings can be greater than 150% of the average of the two
preceding years when including mandatory overtime earnings.
Plan B Reduction
If you are a Plan B member, your benefit may be subject to a slight
- There are only 2 triggers for the Plan B reduction. The Plan B
reduction will commence:
- When you reach your full social security age, or
- If you receive a Social Security Disability Award at any point.
- Regardless of whether you collect your non-disability Social
Security benefit early (prior to reaching your full social security age)
or late (beyond your full social security age), the Plan B reduction
kicks in based on you attaining your full social security age.
- You can determine the amount of your Plan B reduction by taking one
half of your percent of entitlement and then applying the resulting
percentage to a fixed statutory figure of $4,800.00.
||Percent of Entitlement
||$4,800.00 (statutory figure)
- The percent of entitlement for a Tier I member with 30 years of
service is 60% (2% x 30 years of service). Therefore, the corresponding
annual Plan B Reduction for a Tier I member with 30 years of service
would be $1,440.00 per year or $120.00 per month.
- 1/2 x 60% Percent of Entitlement (= 30%) x $4,800.00 = 1,440.00
Cost of Living Adjustment
- Your pension is subject to an annual Cost of Living Adjustment (COLA).
- For retirements prior to June 30, 2022, these cumulative raises will be paid each year on either January
1st or July 1st depending on your date of retirement (DOR).
- For retirements July 1, 2022 forward, these raises will be based
on the language in the
- Currently you must be retired at least 9 full months in order to
qualify for your first raise(COLA).
- Thereafter, your annual cost of living adjustment will be paid on
the COLA anniversary date, which corresponds with your DOR.
- Your COLA will range from a minimum of 2% to a maximum of 7.5%
based on the following formula which takes into account a portion of the
increase in the Consumer Price Index for Urban Wage Earners and Clerical
Workers (CPI-W) for the 12 months immediately preceding your COLA
60% of the annual CPI-W increase up to 6%
75% of the annual CPI-W increase above 6%
