Updated October 30, 2026. Quick answer: KPERS 3 members (hired January 1, 2015 or after) can retire with full benefits at age 65 with 5 years of service or at age 60 with 30 years, and with reduced benefits at age 55 with 10 years. KPERS 2 members (hired July 1, 2009 up to January 1, 2015) have the same full-benefit ages. KPERS 1 members (hired before July 1, 2009) have their own ladder, including an 85-point rule.
KPERS 3
The web page’s table row for the newest group reads: “KPERS 3 (hired Jan. 1, 2015 and after) Full Retirement Benefits Age 60 30 Years of Service Age 65 5 Years of Service Reduced Retirement Benefits Age 55 10 Years of Service”.
KPERS 2
The membership guide lists for the middle group: “Age 65 with five years of service credit • Age 60 with 30 years of service credit”. “The earlier you retire, the more your benefit is reduced. If you retire before age 60 with at least 30 years of service, there is less of a reduction to your benefit.”
KPERS 1
“Age 65 with at least one year of service credit • Age 62 with at least ten years of service credit • Any age when your age and years of service credit added together equal 85 (85 points)”. “The 85 point rule is when your age and years of service credit added together equal 85.” “You can receive reduced benefits beginning at age 55 with ten years of service.” “Benefits are reduced by 0.6 percent for each month you are between age 55 and 60, and 0.2 percent for each month you are between age 60 and 62.”
Vesting
For KPERS 1 and 2 the membership guide says: “You will become vested with five years of service credit.” The guide adds that a member who was inactive on July 1, 2009 is not eligible for five-year vesting unless an active Board of Regents member or working in a non-covered position for a KPERS employer. The guide does not state KPERS 3 vesting.
What the pension is based on
KPERS 2: “1.85% for participating service 1% or 0.75% for prior years of service (time worked for an employer before affiliation with KPERS)”. Final average salary: “Your final average salary is an average of your highest 5 years of salary, excluding additional compensation, such as payments for unused sick and annual leave.” For KPERS 1, the factors are “Service Before 2014: 1.75%” and “Service January 2014 and after: 1.85%”. KPERS 3: “At retirement, both your contribution account balance and your retirement credits are used to calculate your lifetime monthly benefit, along with some actuarial factors.”
A worked example with invented numbers
Take an invented KPERS 2 member with 25 years of participating service. That is 25 years at 1.85%, or 46.25% (computed) of a final average salary of $60,000 (invented, for the computation), which comes to $27,750 a year (computed).
What the documents do not say
The percent reductions for early retirement under KPERS 2 appear only in a table in the guide, and no source read prints KPERS 3 reduction percentages, so this page states none for those groups. The membership guide covers the first two groups only, is undated, and prints a 1.75% multiplier for both, while KPERS’s current web page prints 1.85% for KPERS 2 and for KPERS 1 service from January 2014, so the web page is used for multipliers. KPERS 3 uses a different calculation, in which the web page says both the contribution account balance and retirement credits are used, and this page states no per-year multiplier for it, so the worked example uses KPERS 2. KPERS 3 vesting is not stated. Correctional members, KP&F and judges are not covered.
Common mistakes
- Treating KPERS 3 like a final-pay plan. The web page says both the contribution account balance and retirement credits are used, and this page states no per-year multiplier for it.
- Using the KPERS 1 ladder for a newer hire. Age 62 with 10 years and the 85-point rule are listed for the oldest group.
- Retiring at 55 and expecting a full benefit. Age 55 with 10 years is the reduced benefit age in each group.
