Buying Colorado PERA service credit

Each year of service adds 2.5% of your highest average salary to a full Colorado PERA benefit, and can bring your full-benefit date closer. PERA lets you buy some kinds of service.

Colorado specificsOn a full benefit, a bought year is worth 2.5% of HAS: $150 a month for life on a $6,000 HAS. More service can also move your full-benefit date under the Rule of 80 to 90. If you took a refund, see leaving PERA work; compare with working one more year. Add years to a PERA 6, age 58, 20 years (reduced) example in the calculator.

How you earn it

Generally a month of service credit for each month with salary of at least 80 x federal minimum wage ($7.25/hour); less is prorated. School and DPS Division credit is weighted (see highestAverageSalary.schoolServiceCredit). Your PERA Benefits p. 3, Service Credit; School and DPS Service Credit fact sheet PDF pp. 1-2

What you can buy

You can buy service credit based on a refunded/rolled-over DB Plan account or on employment not covered by PERA or another retirement program. Non-covered service costs the actuarial cost of the added benefit, based on HAS, age and membership start date. For members who began on or after Jan. 1, 2007, buying back a refunded account costs the amount refunded plus interest plus 1% of HAS per month purchased.

To buy, you must be an active PERA member with at least one year of service credit; purchases must be paid in full before you retire. Understanding Your Benefit Estimate PDF p. 2, Service Credit Years

What a year adds

On a full benefit, each year adds 2.5% of HAS: $150 a month on a $6,000 HAS, for life. In a reduced box it can also move you up your HAS table. Your PERA Benefits p. 7, Defined Benefit Calculation; C.R.S. 24-51-603(1)(a) Weigh that against PERA's quoted cost.

To see how much a bought year is worth to you, compare boxes in the reduced retirement tables, check the one more year examples, or try a PERA 6, age 58, 20 years (reduced) example in the calculator and add years. If you took a refund when you left an earlier PERA job, the leaving PERA page explains what you gave up.
