New Mexico PERA Retirement Calculator

The 3% formula: one of the most generous in the country

Plan A's 3.0% benefit factor puts New Mexico PERA among the most generous defined benefit pension systems for state employees in the United States. Most state systems use 1.5% to 2.5%. California's CalPERS uses 2.0% to 2.7% depending on tier and age. Texas TRS uses 2.3%. Ohio STRS uses 2.2%.

The math on Plan A is striking. A member who retires with 30 years of service receives 90% of their final average salary (30 x 3.0% = 90%), which is the plan maximum. That's the highest replacement rate of any common benefit calculation in the country for a 30-year career. On a $70,000 FAS, that's $63,000 per year, or $5,250 per month, for life.

Even at 25 years, Plan A pays 75% of FAS. A $65,000 salary produces $48,750 per year starting at any age once you hit 25 years of service, with no minimum age requirement. Compare that to a 401(k) worker who saved 10% of the same salary for 25 years and earned 7% annually: they'd have roughly $500,000, which at a 4% safe withdrawal rate produces $20,000 per year. The Plan A pension at 25 years produces more than twice that income.

Why the state cut it to 2.35% for post-2013 members

New Mexico PERA's funding ratio declined sharply after the 2008 financial crisis. The combination of a 3.0% benefit factor, a relatively generous COLA, no Social Security participation for most members, and investment losses created a substantial unfunded liability. The state's pension system was projected to run out of assets within decades if benefits weren't restructured.

The 2013 reforms created Plan B with a 2.35% formula, replaced the Rule of 80 with a stricter Rule of 90 for new members, and removed the 25-years-any-age provision. These changes significantly reduce the liability for new hires while protecting existing members' accrued benefits under Plan A.

Plan B's 2.35% formula still isn't low by national standards. But it's 21% less than Plan A per year of service, and the more restrictive retirement eligibility means Plan B members also work longer before collecting. The combined effect on lifetime benefits is substantial. A Plan A member who retires at 47 with 25 years on a $65,000 FAS and collects for 38 years receives a total nominal payout around $1.85 million. A Plan B member can't retire without either reaching Rule of 90 (minimum age 60), age 65 with 5 years, or age 67 with 5 years. Their earliest realistic retirement is years later.

Plan A's 25-years-any-age provision

This is genuinely unusual. Most states that once offered "years of service only" retirement paths have eliminated them in post-recession reforms. New Mexico kept it for Plan A members. If you have 25 years of PERA service and you're a Plan A member, you can retire at any age over 55 with a full unreduced benefit. No age floor beyond 55 applies. Age 47, age 50, age 52 with 25 years. All qualify.

The financial implications are significant in both directions. A member who retires at 47 and lives to 87 collects 40 years of pension income. At $48,750 per year with a 2% COLA (when paid), the cumulative nominal payout approaches $2.4 million. But that also means 40 years of inflation exposure, and 40 years with no Social Security supplementing it.

Member contributions to PERA are high relative to other state systems. Most PERA members contribute around 10.7% of salary. That's substantially more than the 6-9% common in other states. The higher contribution rate is part of what funds Plan A's generous benefit structure.

Rule of 80 vs Rule of 90

Plan A uses the Rule of 80: age plus years of service must reach 80, with a minimum age of 55. Someone who's 55 with 25 years qualifies (80 exactly). Someone who's 60 with 20 years also qualifies (80 exactly). You could also reach the Rule of 80 at 58 with 22 years, or 62 with 18 years.

Plan B uses the Rule of 90 with a minimum age of 60. That's a harder bar to clear. The 10-point increase in the required sum, combined with a 5-year higher minimum age, effectively pushes unreduced retirement 5 to 10 years later for a typical career employee compared to Plan A's Rule of 80 path. A Plan B member with 30 years of service can't use the Rule of 90 until age 60 (60 + 30 = 90). A Plan A member with the same career could retire at 50 (50 + 30 = 80, and 50 is below the minimum age of 55, so they'd need to wait until 55). Regardless, Plan A members routinely retire years earlier than their Plan B counterparts.

No Social Security for most members

The majority of New Mexico PERA members don't participate in Social Security for their covered state employment. This means the pension is the primary retirement income source, with no Social Security floor below it. At Plan A's 90% replacement rate, this is workable. At Plan B's more modest replacement rate on a shorter career, it's a harder picture.

The Social Security Fairness Act of January 2025 repealed the Windfall Elimination Provision and Government Pension Offset, which previously reduced Social Security benefits for PERA members who had any outside Social Security-covered work. If you worked in a Social Security-covered job before or after your PERA career, check your SSA record. Your benefit may have increased.

COLA history and suspension risk

New Mexico PERA's COLA formula is 2% per year when CPI is at or above 2%, and matches CPI below that. In theory, this means retirees keep pace with inflation. In practice, the COLA has been suspended multiple times when the system's funded ratio dropped below certain thresholds. During the 2010s funding crisis, retirees saw COLAs reduced or eliminated for extended periods.

The COLA suspension risk is real. Planning conservatively means running the numbers at 0% COLA as well as 2%. The gap between those two scenarios over a 30-year retirement is substantial. On a $5,250 monthly benefit, 30 years at 2% compounding produces cumulative benefits of roughly $2.6 million. At 0% COLA, the same benefit produces $1.9 million. The $700,000 difference is effectively the value of the COLA if it's paid in full.
