Bottom line
NYSTRS starts with pension factor × age factor × final average salary. The multiplier pattern changes by tier and service, so a correct estimate needs your exact tier, service credit, FAS, and retirement age.Key facts
- 3 consecutive school years generally determine FAS for Tiers 2–6.
- 2% per year applies to Tier 4 service from 20 through 30 years.
- 35% is the Tier 6 pension factor at exactly 20 years of service.
The NYSTRS formula has three moving parts
NYSTRS describes the maximum annual service pension as pension factor multiplied by any applicable age factor and then by final average salary. The pension factor comes from tier and service credit. The age factor reflects whether the retirement date meets the tier’s unreduced age-and-service rules. Final average salary, or FAS, is the salary base applied after those percentages are determined.
Because all three parts interact, a shortcut such as “two percent times years” can be wrong. Tier 4 reaches 2% per year once service is at least 20 years, while Tier 5 does not reach a 2% factor for all service until 25 years. Tier 6 uses 1.67% below 20 years, 1.75% at 20 years, then 35% plus 2% for each year beyond 20.
Final average salary is not simply your last paycheck
For Tiers 2–6, NYSTRS generally uses the highest three consecutive school years of salary, wherever those years occur in the record. A 2024 law changed Tier 6 from a five-year to a three-year FAS and aligned its lookback limits more closely with Tier 4. Certain non-regular payments, buyouts, and salary spikes above the tier’s statutory limits can be excluded from the calculation.
For Tiers 3–6, the three-year FAS calculation excludes yearly salary increases above 10% of the average of the prior two years. Tier 6 also has statutory limits on includable compensation. That means a large final-year payment may not flow dollar-for-dollar into the pension base. Use the FAS shown by NYSTRS or test the actual salary history against the handbook rules before multiplying.
A worked example shows why the tier matters
Consider a Tier 4 member with 30 years of service, an FAS of $90,000, and no age reduction. Tier 4 uses 2% per year for the first 30 years, creating a 60% pension factor. Multiplying 60% by $90,000 produces a maximum annual pension of $54,000 before choosing a survivor option or accounting for any loan-related reduction. The monthly maximum would be $4,500 before deductions.
Now consider a Tier 6 member at age 63 with 25 years and the same $90,000 FAS. The pension factor is 35% for the first 20 years plus 2% for each of five additional years, or 45%. With no age reduction at 63, the maximum annual pension would be $40,500. The identical salary therefore produces a different benefit because the service formula is tier-specific.
Build the estimate in the same order NYSTRS uses
Start with credited service as of the proposed retirement date, including months rather than rounding to whole years. Apply the pension-factor schedule for the correct tier. Then determine whether the age factor is 100% or reduced. Only after those percentages are set should you multiply by FAS.
For a Tier 4 member with 19 years, for example, the pension factor is 1.67% for each year rather than 2%. At 20 years, the factor becomes 2% for all service. That one-year boundary can move the pension factor substantially. The same kind of breakpoint occurs for Tier 5 at 25 years and Tier 6 at 20 years, so exact service credit can matter more than a rough career length.
| Tier | Service range | Pension factor |
|---|---|---|
| 3–4 under Article 15 | Under 20 years | 1.67% per year |
| 3–4 under Article 15 | 20–30 years | 2% per year for all service |
| 5 | Under 25 years | 1.67% per year |
| 5 | 25–30 years | 2% per year for all service |
| 6 | Under 20 years | 1.67% per year |
| 6 | Exactly 20 years | 1.75% per year for all service |
| 6 | Over 20 years | 35% + 2% per year beyond 20 |
Check whether an age factor reduces the pension factor
The maximum pension factor can be reduced when retirement occurs before the tier’s unreduced conditions. Tiers 2–4 avoid an age reduction at 62 or at age 55 and later with at least 30 years. Tier 5 avoids it at 62 or at age 57 and later with 30 years. For Tier 6, the 2026 law now allows age 58 and 30 years; otherwise the age-only unreduced point is 63.
Age reductions are prorated by month, so two retirement dates within the same school year can produce different percentages even if FAS and service are otherwise similar. When comparing dates, keep the pension factor constant first, then change the age factor. That isolates how much of the difference comes from retiring earlier rather than from earning another month or year of service.
| Tier | Age/service for 100% age factor | If not met |
|---|---|---|
| 2–4 | 62, or 55+ with 30 years | Age factor may reduce benefit |
| 5 | 62, or 57+ with 30 years | Age factor may reduce benefit |
| 6 | 63, or 58+ with 30 years | Age factor may reduce benefit |
Understand what can and cannot enter FAS
The three-year FAS can include regular teaching pay and listed teaching-related duties such as coaching, tutoring, summer school, workshops, and certain chaperoning or supervisory work. It generally excludes non-regular compensation, employer contributions to tax-sheltered accounts, payments outside contract terms, retirement-eve payments, buyouts, termination pay, and pay for duties that are not reasonably incidental to covered educational employment.
Salary growth limits can also trim the amount used in the average. The handbook applies a 10% test for Tiers 3–6, measured against the average of the previous two years. Tier 6 compensation is additionally subject to statutory ceilings. If your last years include a major promotion, extra-duty assignment, or unusual one-time pay, compare the payroll record with the FAS exclusions instead of assuming all reportable earnings will be included.
Turn the annual maximum into a realistic planning figure
The formula produces the Maximum annual pension, which assumes the Maximum benefit payment choice. At retirement, members can choose options that continue payments to a beneficiary; those options reduce the retiree’s monthly amount because they provide survivor protection.
For 2026–27 planning, request an official estimate for each retirement date you are seriously comparing and keep the payment option constant across scenarios. That makes the comparison meaningful. A self-calculation is useful for understanding which variable changed, but the personal record controls service credit, FAS, tier, loans, and option pricing.
Before you make a decision
- Confirm your NYSTRS tier and exact service credit for the proposed date.
- Identify the pension-factor breakpoint that applies to your service level.
- Calculate whether an age factor is 100% or reduced on that date.
- Review the three-year FAS record for excluded or capped compensation.
- Compare official NYSTRS estimates using the same payment option.
Frequently asked questions
What is the basic NYSTRS pension formula?
NYSTRS states the maximum annual pension as pension factor × age factor, if one applies, × final average salary. The pension factor depends on tier and service credit. The age factor can reduce the amount for an early retirement. FAS supplies the salary base after the percentage factors are determined.
Does NYSTRS use the highest three years of salary?
For Tiers 2–6, NYSTRS generally uses the highest three consecutive school years of eligible salary. Those years do not have to be the last three. Salary-spike limits and exclusions for certain non-regular or termination-related payments can change the amount that actually enters the final average salary calculation.
How is a Tier 6 NYSTRS pension calculated after 20 years?
At exactly 20 years, Tier 6 uses 1.75% per year for all service, which equals a 35% pension factor. With more than 20 years, the factor starts at 35% and adds 2% for each additional year. An age factor may still reduce that amount unless an unreduced retirement condition is met.
What would 30 years in Tier 4 pay with a $90,000 FAS?
If the member has no age reduction, Tier 4 uses a 60% pension factor at 30 years because the first 30 years are credited at 2% per year. Sixty percent of a $90,000 FAS is a $54,000 maximum annual pension, before any survivor-option reduction, loan adjustment, taxes, or deductions.
Can extra-duty pay raise my NYSTRS final average salary?
Some teaching-related extra duties can be included, but not every payment is eligible. The handbook lists includable items such as coaching and tutoring while excluding various non-regular payments, buyouts, and payments outside contract terms. Salary-growth limits can also apply, so verify how the specific earnings were reported and treated by NYSTRS.
