New York Pension Formulas
All New York public defined benefit pensions use the same fundamental formula:
Pension Factor × Age Factor (if applicable) × Final Average Earnings = Annual Pension
The three variables:
- Pension Factor — a cumulative percentage based on your total years of service and your tier's benefit table
- Age Factor — a reduction multiplier applied if you retire before your tier's full benefit age with insufficient service (1.0 = no reduction)
- Final Average Earnings (FAE/FAS) — the average of your highest three consecutive years of earnings in New York public employment, subject to anti-spiking limitations

- see also: New York Pension Systems Overview — background on all seven systems, bargaining units, and the Taylor Law
- see also: Employer Contribution Rates — how much your employer pays on top of your salary (ERS avg 17.6%, PFRS avg 36.5% of payroll)
All New York pension formulas, contribution rates, and benefit tiers are set exclusively by the State Legislature through the Retirement and Social Security Law. RSSL §470 explicitly prohibits negotiation of pension benefits through collective bargaining. Unions influence pension policy through legislative advocacy (e.g., the "Fix Tier 6" movement), not at the bargaining table.
Employee contributions are listed with each formula below. For employer contribution rates, see the Employer Contributions section in the systems overview.
ERS Formulas (Employees' Retirement System)
ERS covers state employees and participating local government employees outside NYC in non-uniformed positions. Most members are in the Article 15 Coordinated Plan.
ERS Tiers 3 & 4 (Article 14/15 Coordinated Plan)
| Service Credit | Pension Factor per Year | Cumulative at Milestone |
|---|---|---|
| Less than 20 years | 1.66% of FAE | 33.2% at 20 years |
| 20–30 years | 2.00% of FAE | 60% at 30 years |
| Over 30 years | 1.50% of FAE (beyond 30) | 67.5% at 35 years |
Full benefit age: 62 — or any age with 30+ years of service (no age reduction)
Early retirement: As early as age 55 with 5+ years of service, but with a permanent reduction of up to 27% at age 55
Contributions: 3% of gross salary until 10 years of membership or service, then $0
Example: ERS Tier 4, Age 62, 25 Years of Service, FAE $80,000
Source: NYSLRS Tier 3/4 Publication
| Component | Calculation |
|---|---|
| First 20 years | 20 × 2.00% = 40.0% |
| Next 5 years (years 21–25) | 5 × 2.00% = 10.0% |
| Total pension factor | 50.0% |
| Age factor | 1.0 (age 62, no reduction) |
| Annual pension | 50.0% × $80,000 = $40,000/year ($3,333/month) |
Example: ERS Tier 4, Age 55, 25 Years of Service, FAE $80,000
| Component | Calculation |
|---|---|
| Pension factor (same as above) | 50.0% |
| Age factor at 55 with <30 years | 0.73 (27% reduction) |
| Annual pension | 50.0% × 0.73 × $80,000 = $29,200/year ($2,433/month) |
Example: ERS Tier 4, Age 55, 30 Years of Service, FAE $80,000
| Component | Calculation |
|---|---|
| First 20 years | 20 × 2.00% = 40.0% |
| Next 10 years (years 21–30) | 10 × 2.00% = 20.0% |
| Total pension factor | 60.0% |
| Age factor | 1.0 (30+ years = no reduction regardless of age) |
| Annual pension | 60.0% × $80,000 = $48,000/year ($4,000/month) |
The 30-Year Cliff
For Tiers 3 and 4, reaching 30 years of service is a game-changer: it eliminates all early retirement penalties and locks in a 60% replacement rate. One additional year beyond 30 adds only 1.5% (not 2%), so the marginal value drops after 30.
ERS Tier 5 (Article 15 Coordinated Plan)
| Service Credit | Pension Factor per Year | Cumulative at Milestone |
|---|---|---|
| Less than 20 years | 1.66% of FAE | 33.2% at 20 years |
| 20–30 years | 2.00% of FAE | 60% at 30 years |
| Over 30 years | 1.50% of FAE (beyond 30) | 67.5% at 35 years |
The pension factor table is identical to Tiers 3 & 4. The differences are:
- Full benefit age: 62 (same), but no 30-year escape from early retirement penalties (except for Uniformed Court and Peace Officers)
- Early retirement reduction: Up to 38.33% at age 55 (steeper than Tiers 3–4)
- Contributions: 3% of gross salary for entire career
- Overtime cap: Pensionable overtime is capped, increasing 3% per calendar year
Example: ERS Tier 5, Age 55, 30 Years of Service, FAE $80,000
| Component | Calculation |
|---|---|
| First 20 years | 20 × 2.00% = 40.0% |
| Next 10 years (years 21–30) | 10 × 2.00% = 20.0% |
| Total pension factor | 60.0% |
| Age factor at 55 | 0.6167 (38.33% reduction) |
| Annual pension | 60.0% × 0.6167 × $80,000 = $29,600/year ($2,467/month) |
Tier 5 vs Tier 4 at Age 55 with 30 Years
A Tier 4 member retiring at 55 with 30 years gets $48,000/year (no reduction). A Tier 5 member with identical service and salary gets $29,600/year — a $18,400/year difference solely due to losing the 30-year early retirement exemption.
ERS Tier 6 (Article 15 Coordinated Plan)
| Service Credit | Pension Factor per Year | Cumulative at Milestone |
|---|---|---|
| Less than 20 years | 1.66% of FAE | 33.2% at 20 years |
| Exactly 20 years | 1.75% of FAE (applied to all 20) | 35% at 20 years |
| Over 20 years | 35% base + 2.00% per year beyond 20 | 55% at 30 years |
Full benefit age: 63
Early retirement: As early as age 55, but with a permanent reduction of up to 52% at age 55 (6.5% per year before age 63)
Vesting: 10 years (up from 5 years in all prior tiers)
Contributions: 3%–6% of gross salary based on earnings (sliding scale), for entire career
Example: ERS Tier 6, Age 63, 19 Years of Service, FAE $35,000
Source: NYSLRS Official Tier 6 Publication
| Component | Calculation |
|---|---|
| 19 years at 1.66% | 19 × 1.66% = 31.54% |
| Age factor | 1.0 (age 63, no reduction) |
| Annual pension | 31.54% × $35,000 = $11,039/year ($920/month) |
Example: ERS Tier 6, Age 63, 20 Years of Service, FAE $35,000
Source: NYSLRS Official Tier 6 Publication
| Component | Calculation |
|---|---|
| 20 years at 1.75% | 20 × 1.75% = 35.0% |
| Age factor | 1.0 (age 63, no reduction) |
| Annual pension | 35.0% × $35,000 = $12,250/year ($1,021/month) |
The 20-Year Bump
Notice the jump from 19 to 20 years: the pension goes from $11,039 to $12,250 — an $1,211/year increase for one additional year of service. This is because reaching 20 years retroactively applies 1.75% to all 20 years instead of 1.66%. Every year you work past 20 then adds a full 2%.
Example: ERS Tier 6, Age 63, 32 Years of Service, FAE $35,000
Source: NYSLRS Official Tier 6 Publication
| Component | Calculation |
|---|---|
| First 20 years | 20 × 1.75% = 35.0% |
| Next 12 years (years 21–32) | 12 × 2.00% = 24.0% |
| Total pension factor | 59.0% |
| Age factor | 1.0 (age 63, no reduction) |
| Annual pension | 59.0% × $35,000 = $20,650/year ($1,721/month) |
Example: ERS Tier 6, Age 63, 25 Years of Service, FAE $80,000
| Component | Calculation |
|---|---|
| First 20 years | 20 × 1.75% = 35.0% |
| Next 5 years (years 21–25) | 5 × 2.00% = 10.0% |
| Total pension factor | 45.0% |
| Age factor | 1.0 (age 63, no reduction) |
| Annual pension | 45.0% × $80,000 = $36,000/year ($3,000/month) |
Compare this to the same scenario under Tier 4 at age 62: pension factor would be 50% → $40,000/year. That's a $4,000/year gap — the core of the "Fix Tier 6" argument.
Side-by-Side: ERS Tier 4 vs Tier 6
| Scenario | Tier 4 (at age 62) | Tier 6 (at age 63) | Difference |
|---|---|---|---|
| 20 years, $80,000 FAE | 40.0% → $32,000 | 35.0% → $28,000 | −$4,000/year |
| 25 years, $80,000 FAE | 50.0% → $40,000 | 45.0% → $36,000 | −$4,000/year |
| 30 years, $80,000 FAE | 60.0% → $48,000 | 55.0% → $44,000 | −$4,000/year |
| 30 years, $80,000 FAE, age 55 | 60.0% → $48,000 (no reduction) | 55.0% × 0.48 → $21,120 | −$26,880/year |
The age-55-with-30-years scenario is the most devastating comparison: a Tier 4 member gets the full benefit with no reduction, while a Tier 6 member faces a 52% penalty. This is why the Fix Tier 6 campaign focuses heavily on early retirement penalties.
PFRS Formulas (Police & Fire Retirement System)
PFRS covers police officers and paid firefighters of participating employers outside NYC. Benefits vary significantly based on whether the member is in a special plan (20- or 25-year) or a regular plan.
PFRS Special 20-Year Plans (§384, §384-d)
Source: NYSLRS PFRS Membership Milestones
| Service Credit | Benefit |
|---|---|
| 20 years | 50% of FAE (regardless of age) |
| Each year beyond 20 (if §384-e adopted) | Additional benefit per year, up to 32 years max |
No age requirement — members retire based solely on completing 20 years of qualifying service. This is the classic police/fire benefit that mirrors many other states' public safety plans.
PFRS Special 25-Year Plans (§384-e, §384-f)
| Service Credit | Benefit |
|---|---|
| 25 years | 50% of FAE (regardless of age) |
| Each year beyond 25 (if applicable) | Additional benefit per year, up to 32 years max |
PFRS Regular Plans (Tiers 3–6)
Members not in special plans follow formulas similar to ERS:
- Tiers 3–5: Same 1.66%/2%/1.5% stepped formula as ERS
- Tier 6: Same 1.66%/1.75%/2% formula as ERS Tier 6
- Full benefit ages: 62 (Tiers 3–5), 63 (Tier 6)
- see also: PFRS Tier 6 Benefit Summary
- see also: PFRS Benefits Book (PDF)
Example: PFRS Tier 5, 20-Year Special Plan, 22 Years of Service, FAE $95,000
| Component | Calculation |
|---|---|
| Base benefit at 20 years | 50% of FAE |
| Additional service (years 21–22) | Per employer's adopted section |
| Age factor | N/A (no age requirement in special plans) |
| Minimum annual pension | 50.0% × $95,000 = $47,500/year ($3,958/month) |
NYSTRS Formulas (Teachers Outside NYC)
NYSTRS formulas follow a similar stepped structure to ERS but with some tier-specific differences.
NYSTRS Tiers 1 & 2
Tier 1 and 2 formulas are the most generous and the most complex:
| Component | Formula |
|---|---|
| NYS service before 1959 | 1.8% per year |
| NYS service after 1959 | 2.0% per year |
| Out-of-state service (Tier 1 only, up to 10 years) | 1.0% per year |
| Maximum pension factor | Generally 79% (includes possible Benefit Enhancement/Article 19 credit) |
| Service-related reduction | Pension factor reduced by 5% for each year NYS service is under 20 years |
Full benefit age: 55 with 30+ years; otherwise 62
FAS: Three consecutive years for most; Tier 1 members with pre-6/17/1971 membership may use a five-year FAS that includes termination pay and non-regular compensation
NYSTRS Tiers 3 & 4
| Service Credit | Pension Factor per Year | Cumulative at Milestone |
|---|---|---|
| Less than 20 years | 1.67% of FAS | 33.4% at 20 years |
| 20–30 years | 2.00% of FAS | 60% at 30 years |
| Over 30 years (Tier 4) | 1.50% of FAS (beyond 30) | 67.5% at 35 years |
| Over 30 years (Tier 3) | Capped at 60% maximum | 60% cap |
Full benefit age: 62 — or age 55 with 30+ years (no age reduction)
Contributions: 3% of salary for first 10 years, then $0
Tier 3 members may retire under either the Tier 3 or Tier 4 benefit formula and virtually all choose Tier 4 because the Tier 3 formula requires a Social Security offset beginning at age 62.
Example: NYSTRS Tier 4, Age 55, 30 Years of Service, FAS $90,000
Source: NYSTRS DRO Guide — 2% × 30 years = 60%
| Component | Calculation |
|---|---|
| First 20 years | 20 × 2.00% = 40.0% |
| Next 10 years (years 21–30) | 10 × 2.00% = 20.0% |
| Total pension factor | 60.0% |
| Age factor | 1.0 (30+ years = no reduction) |
| Annual pension | 60.0% × $90,000 = $54,000/year ($4,500/month) |
This is the "gold standard" for New York teachers — retire at 55 with 30 years and walk away with 60% of your highest three-year average salary, no penalty.
NYSTRS Tier 5
| Service Credit | Pension Factor per Year | Cumulative at Milestone |
|---|---|---|
| Less than 25 years | 1.67% of FAS | 41.75% at 25 years |
| 25–30 years | 2.00% of FAS | 51.75% at 30 years |
| Over 30 years | 1.50% of FAS (beyond 30) | — |
Key difference from Tiers 3–4: The bump to 2% doesn't happen until 25 years (vs 20 years in Tiers 3–4). This means a Tier 5 member with 20 years gets 33.4% while a Tier 4 member gets 40%.
Full benefit age: 62 — or age 57+ with 30+ years (no age reduction)
Early retirement reduction: Applied if retiring before 62 with less than 30 years, or before 57 with 30+ years

NYSTRS Tier 6
| Service Credit | Pension Factor per Year | Cumulative at Milestone |
|---|---|---|
| Less than 20 years | 1.67% of FAS | 33.4% at 20 years |
| Exactly 20 years | 1.75% (applied to all 20) | 35% at 20 years |
| Over 20 years | 35% base + 2.00% per year beyond 20 | 55% at 30 years |
Full benefit age: 63 (no exceptions)
NYSUT §1312 provision: Teachers represented by NYSUT-affiliated unions may qualify for an unreduced benefit at age 57 with 30+ years of service, with the additional actuarial cost borne by the employee.
Example: NYSTRS Tier 6, Age 63, 31 Years of Service, FAS $100,000
Source: NYSTRS Tier 6 Presentation
| Component | Calculation |
|---|---|
| First 20 years | 20 × 1.75% = 35.0% |
| Next 11 years (years 21–31) | 11 × 2.00% = 22.0% |
| Total pension factor | 57.0% |
| Age factor | 1.0 (age 63, no reduction) |
| Annual pension | 57.0% × $100,000 = $57,000/year ($4,750/month) |
Example: NYSTRS Tier 6, Age 55, 30 Years of Service, FAS $100,000
Source: NYSTRS Tier 6 Presentation
| Component | Calculation |
|---|---|
| First 20 years | 20 × 1.75% = 35.0% |
| Next 10 years (years 21–30) | 10 × 2.00% = 20.0% |
| Total pension factor | 55.0% |
| Age factor at 55 | 0.48 (52% reduction) |
| Age-adjusted pension factor | 55.0% × 0.48 = 26.4% |
| Annual pension | 26.4% × $100,000 = $26,400/year ($2,200/month) |
Compare this to Tier 4 at age 55 with 30 years: $60,000/year. The Tier 6 teacher receives less than half.
NYCERS Formulas (NYC Civilian Employees)
NYCERS Tier 4 members in the standard 62/5, 57/5, or 55/25 plans use the same stepped formula:
NYCERS Tiers 3 & 4 (62/5 Plan)
| Service Credit | Pension Factor per Year | Cumulative at Milestone |
|---|---|---|
| Less than 20 years | 1.67% of FAS | 33.4% at 20 years |
| 20–30 years | 2.00% of FAS | 60% at 30 years |
| Over 30 years | 1.50% of FAS (beyond 30) | — |
FAS: Three-year average of wages earned
NYCERS Tier 6 (63/5 Basic Plan)
| Service Credit | Pension Factor per Year | Cumulative at Milestone |
|---|---|---|
| Less than 20 years | 1.67% of FAS | 33.4% at 20 years |
| Exactly 20 years | 1.75% (applied to all 20) | 35% at 20 years |
| Over 20 years | 35% base + 2.00% per year beyond 20 | 55% at 30 years |
Full benefit age: 63
Overtime cap: $20,958 in 2025, adjusted annually by CPI
NYCERS Special Plans (Tier 6)
NYCERS administers numerous 25-year special plans for Tier 6 members in specific uniformed and semi-uniformed titles:
| Plan Code | Title Group | Retirement Eligibility |
|---|---|---|
| 6EM-25 | Emergency Medical Technicians | 25 years of service, any age |
| 6DI-25 | Fire Alarm Dispatchers | 25 years of service, any age |
| 6DS-25 | Deputy Sheriffs | 25 years of service, any age |
| 6SO-25 | Special Peace Officers | 25 years of service, any age |
| 6AU-25 | Automotive Members | 25 years of service, age 50+ |
| 6PC-25 | Police Communications Technicians | 25 years of service, any age |
| 6FP-25 | Fire Protection Inspectors | 25 years of service, any age |
NYC Police & Fire Pension Formulas
NYC Police Pension Fund & NYC Fire Pension Fund
| Tier | Service Requirement | Benefit at Retirement |
|---|---|---|
| Tier 2 (pre-7/1/2009) | 20 years of service | 50% of FAS, regardless of age |
| Tier 3 (on/after 7/1/2009) | 22 years of service | 50% of FAS, regardless of age |
There is an additional benefit per year beyond the minimum service requirement. The Tier 3 change from 20 to 22 years has been a major retention issue for the NYPD, with active legislation to restore the 20-year standard.
Example: NYC Police, Tier 2, 20 Years of Service, FAS $116,200
| Component | Calculation |
|---|---|
| Base benefit | 50% of FAS |
| Annual pension | 50.0% × $116,200 = $58,100/year ($4,842/month) |
Tier 6 — How the 2012 Reform Changed Formulas
Chapter 18 of the Laws of 2012, signed by Governor Cuomo on March 16, 2012, was the most significant pension reform in New York since the tier system began in 1973. It applies to all members joining on or after April 1, 2012 across ERS, PFRS, NYSTRS, and all five NYC systems.
Key Tier 6 Provisions
| Provision | Pre-Tier 6 (Tiers 3–5) | Tier 6 |
|---|---|---|
| Pension factor at 20 years | 40% (2% × 20) | 35% (1.75% × 20) |
| Pension factor at 30 years | 60% | 55% |
| Full benefit age | 62 | 63 |
| Early retirement (55, <30 yrs) | 27%–38.33% reduction | 52% reduction |
| 30-year escape from penalty | Yes (Tiers 3–4) | No |
| Vesting | 5 years | 10 years |
| Contributions | 3%, stops at 10 years (Tiers 3–4) | 3%–6% sliding scale, entire career |
| FAE period | 3 years | 3 years (changed from 5 in 2024) |
| Overtime cap | None (Tiers 3–4); statutory cap (Tier 5) | $15,000 + CPI ($20,958 in 2025) |
| Sick leave credit | Up to 165–200 days | Up to 100–200 days |
Who Is in Tier 6?
You are a Tier 6 member if you first joined any New York State or New York City public retirement system on or after April 1, 2012. Unlike California's PEPRA, there is no reciprocity-based exception — if your first day of membership in any NY public retirement system is on or after that date, you are Tier 6 regardless of prior out-of-state public service.
Final Average Earnings (FAE/FAS) Rules
The Three-Year Calculation
For all tiers (since 2024), FAE is the average of your three highest consecutive years of earnings in New York public employment. This was originally five years for Tier 6 but was legislatively changed to three years effective April 2024.
Anti-Spiking Limitations
| Rule | Tiers 3–5 | Tier 6 |
|---|---|---|
| Earnings growth limit | Any year cannot exceed average of prior 2 years by >10% | Any year cannot exceed prior year by >20% |
| Overtime cap | None (Tiers 3–4); statutory cap (Tier 5) | $15,000 base + CPI annually |
| Governor's salary cap | N/A | Earnings above the Governor's salary excluded |
| Excluded payments | Unused sick leave, termination pay, vacation lump sums, time not worked | Same, plus lump sum vacation, earnings from non-primary employers |
| IRC §401(a)(17) limit | Applies to members joining on/after 4/1/1996 | Applies |

Cost-of-Living Adjustment (COLA)
New York's permanent COLA applies to all seven major pension systems (ERS, PFRS, NYSTRS, NYCERS, NYCTRS, NYCPPF, FDNY) under the same statutory rules. It is far more limited than California or federal COLAs.
How NY COLA Works
| Rule | Detail |
|---|---|
| Rate | 50% of the annual rate of inflation (CPI), rounded up to the nearest tenth |
| Floor | Never less than 1% per year |
| Ceiling | Never more than 3% per year |
| Base | Applied only to the first $18,000 of the annual Single Life Allowance |
| Maximum annual increase | $540 (3% × $18,000), or $45/month |
| Eligibility | Age 62 with 5+ years retired, OR age 55 with 10+ years retired, OR disability pension 5+ years |
The $18,000 base has not been increased since COLA was enacted in 2000. In today's dollars, $18,000 in 2000 is equivalent to roughly $32,000+ — meaning the COLA base covers an increasingly small fraction of typical pensions.
Worked Example: NY COLA Over 30 Years
For a retiree with a $60,000 annual pension and an assumed average COLA rate of 1.5%:
| Year | COLA-eligible portion | Annual increase | Cumulative pension |
|---|---|---|---|
| 0 | — | — | $60,000 |
| 1 | $18,000 × 1.5% | $270 | $60,270 |
| 5 | Compounds on $18K base | ~$1,389 total | $61,389 |
| 10 | ~$2,895 total | $62,895 | |
| 20 | ~$6,210 total | $66,210 | |
| 30 | ~$10,034 total | $70,034 |
The remaining $42,000 of this pension receives zero COLA — no inflation protection at all. Compare this to a CalPERS retiree with the same $60,000 pension who would receive $108,680/year after 30 years of 2% compounding.
Why This Matters
NY COLA is the weakest inflation protection of any major public pension system in the country:
- California (CalPERS): 2% compounding on the full pension
- Federal (CSRS): Full CPI-W on the full annuity
- Federal (FERS): CPI-W "diet COLA" on the full annuity
- New York: 50% of CPI on first $18,000 only
This is a persistent point of frustration for NY retirees and a key focus of the "Fix Tier 6" movement, which advocates for improved COLA among other reforms.

Key Formula Terms
| Term | Definition |
|---|---|
| Pension Factor | The cumulative percentage of FAE earned based on total years of service — the core of the benefit formula |
| Age Factor | A reduction multiplier (between 0 and 1) applied when retiring before full benefit age without sufficient service; 1.0 means no reduction |
| Final Average Earnings (FAE) | Highest three consecutive years of earnings in New York public employment, subject to anti-spiking limitations |
| Final Average Salary (FAS) | Same as FAE — NYSTRS and NYCERS use "FAS" while NYSLRS uses "FAE" |
| Service Credit | Total years and partial years of qualifying public employment |
| Coordinated Plan | The standard ERS retirement plan (Article 15), coordinated with Social Security |
| Special Plan | PFRS plans allowing retirement after 20 or 25 years regardless of age |
| Single Life Allowance | The maximum pension payment option — pays the highest benefit to you, but nothing to beneficiaries after death |
| Option | A pension payment election that reduces your benefit in exchange for continued payments to a beneficiary after death |
