New Mexico PERA Retirement Calculator: How to Use It
New Mexico PERA split into Plan A (3.0% rate, Rule of 80) and Plan B (2.35% rate, Rule of 85) at a July 2013 cutoff. Both plans share a three-year FAS, a 90% cap, and no Social Security coverage. Which plan you're in changes your benefit by a meaningful amount over a full career.
What this calculator does
The New Mexico PERA Retirement Calculator computes your Public Employees Retirement Association defined benefit pension under either Plan A (members enrolled before July 1, 2013) or Plan B (members enrolled on or after July 1, 2013). For Plan A, it applies the 3.0% accrual rate and the Rule of 80 (age plus service equals 80, minimum age 55) along with the 25-years-any-age option. For Plan B, it applies the 2.35% accrual rate and the Rule of 85 (with a minimum of 5 years service) or the 65/5+ threshold. The 90% benefit cap is enforced for both plans.
The calculator uses the three-year FAS and shows your estimated annual and monthly gross pension before taxes. New Mexico PERA members are generally not covered by Social Security for their PERA service, so the pension is the primary retirement benefit from public employment in New Mexico.
What each input means
Plan (A or B)
Plan A applies to members who enrolled in PERA before July 1, 2013. Plan B applies to members who enrolled on or after that date. Check your PERA member statement to confirm. Plan A's 3.0% accrual rate is 28% higher than Plan B's 2.35% rate per year of service. On a 25-year career with a $70,000 FAS, the difference is $52,500 per year under Plan A versus $41,125 under Plan B: more than $11,000 annually for the same career.
Current age
Your age today. Used to determine whether you satisfy the Rule of 80 (Plan A, minimum age 55) or Rule of 85 (Plan B, minimum 5 years service) at your planned retirement date. Also used to check the 25-years-any-age eligibility option for Plan A members and the 65/5+ threshold for Plan B members.
Years of PERA service
Your total creditable service with New Mexico PERA. Includes active service in covered state and local government positions, purchased service credit for prior public employment, and military service deposits. Your annual PERA member statement shows your confirmed credited service balance. Use only finalized credit; pending purchases should not be included until confirmed.
Final Average Salary (3-year)
PERA uses the average of your three highest consecutive years of earnable compensation. For most members near retirement, this is the last three years of base salary. Earnable compensation is your regular base pay; it excludes lump-sum leave payouts, overtime beyond standard hours, and irregular bonuses. Enter the figure you expect this three-year average to be at retirement. If you anticipate salary changes before you retire, adjust accordingly.
Planned retirement age
The age at which you plan to begin collecting your pension. The calculator checks this against your plan's eligibility rules. Plan A members who qualify at 25 years of service regardless of age will see that flagged if they hit that threshold before their planned age. Plan B members without the 25-year option must reach the Rule of 85 or 65/5+.
Understanding the outputs
Plan A pension: 3.0% times years of service times FAS, capped at 90% of FAS. A member with 25 years and a $70,000 FAS gets 0.030 x 25 x $70,000 = $52,500 per year. At 30 years that would be $63,000, and the 90% cap of $63,000 (0.90 x $70,000) is exactly met. Any additional years beyond 30 don't increase the percentage.
Plan B pension: 2.35% times years of service times FAS, capped at 90%. A member with 30 years and the same $70,000 FAS gets 0.0235 x 30 x $70,000 = $49,350. The cap doesn't apply until approximately 38 years of service at the 2.35% rate. So Plan B members with longer careers aren't capped as early as Plan A members.
The COLA of up to 2% when fund conditions allow provides some inflation protection, but it is not guaranteed. Most PERA-covered positions are not covered by Social Security. The pension is the primary retirement income from this employment. If you have Social Security credits from prior private-sector work, the Windfall Elimination Provision may reduce that benefit.
