- Another year of work adds 2.35% of your final average salary in Tiers 1-3. In Tier 4 it adds 1.35%, 2.35%, 3.35% or 2.4% depending on your years of service. If you would retire with a reduction, a year also takes 2.4% off your cut (7.2% in the younger band: before 60 in Tiers 2-4, before 55 in Tier 1).Member Handbook 2025, pp. 13-16
- After you leave NMERB work, your benefit does not grow while your account sits inactive. Benefits you were eligible for before NMERB received your application are lost.Member Handbook 2025, p. 17, Deferred Retirement
How much does one more year add to an NMERB pension?
In Tiers 1-3, one more year of earned service adds 2.35% of your final average salary to your yearly benefit, for life. In Tier 4 it adds that band's rate, from 1.35% to 3.35%. If you'd retire early, each year also shrinks the early cut. Member Handbook 2025, p. 6, Defined Benefit Plan; p. 16, Calculating Retirement Benefits
Your tier sets which of these applies (see which tier am I in?), and the formula page shows the math.
An example: Tier 2, age 60, 20 years
This member qualifies under the Rule of 80 (60 + 20) but is under 65, so the benefit is cut 12%. On a $60,000 final average salary (our illustration), with no raises:
| Retire | Service | Cut | Monthly |
|---|---|---|---|
| July 1, 2026age 60 | 20 | 12% | $2,068.00 |
| July 1, 2027age 61 · +$163/mo | 21 | 9.6% | $2,230.62 |
| July 1, 2028age 62 · +$331/mo | 22 | 7.2% | $2,398.88 |
| July 1, 2029age 63 · +$505/mo | 23 | 4.8% | $2,572.78 |
| July 1, 2030age 64 · +$684/mo | 24 | 2.4% | $2,752.32 |
| July 1, 2031age 65 · +$870/mo | 25 | none | $2,937.50 |

Waiting until 65 raises the check from $2,068 to $2,938 a month, for life. Each year adds 2.35% of salary and removes 2.4% of cut.
Tier 4: what each year earns
In Tier 4 the value of a year depends on how many you already have. A year in the 20-to-30 band earns the most, 3.35%. Member Handbook 2025, p. 14, New Tiered Multipliers; p. 15
| Service | Tier 4 | Tiers 1-3 |
|---|---|---|
| 5 years | 6.75% | 11.75% |
| 10 years | 13.5% | 23.5% |
| 15 years | 25.25% | 35.25% |
| 20 years | 37% | 47% |
| 25 years | 53.75% | 58.75% |
| 30 years | 70.5% | 70.5% |
| 32 years | 75.3% | 75.2% |
| 35 years | 82.5% | 82.25% |
Leaving and waiting is different
If you stop working instead (see leaving teaching), your benefit doesn't keep growing:
With five or more years (or five combined with NMPERA reciprocity) you may leave your account inactive and apply later. If eligible to retire, there is no advantage in deferring beyond age 60, as the benefit does not increase beyond that age in inactive status. Benefits you could have received before your application is received are forfeited. Member Handbook 2025, p. 17, Deferred Retirement
The handbook says there is no advantage in deferring retirement beyond age 60 in inactive status. That matches Tier 1 (the Rule of 75 reduction ends at 60) but not Tiers 2-4, whose Rule of 80 reduction runs to 65. Guide text should not repeat the age-60 statement for Tiers 2-4.
