Bottom line
Tier VI uses 1⅔% of FAS per year under 20 years; at 20 years the base becomes 35% of FAS, then 2% of FAS is added for each year above 20. FAS generally uses five continuous years.Key facts
- 1⅔% of FAS per year applies when Total Service Credit is under 20 years.
- 35% of FAS covers the first 20 years once a Tier VI member reaches 20 years.
- 5 continuous years generally make up the Tier VI Final Average Salary period.
The formula changes at 20 years of Total Service Credit
NYC TRS does not use one flat multiplier for every Tier VI career length. With less than 20 years of Total Service Credit, the regular pension portion equals 1⅔% of Final Average Salary for each year of credit. Once the member reaches 20 years, the formula changes: the first 20 years produce 35% of FAS, and each year above 20 adds another 2% of FAS. That breakpoint can materially change the value of one additional year near the 20-year line.
The published formula describes the regular pension portion, not necessarily every dollar in the eventual retirement allowance. NYC TRS also identifies an Annuity Savings Accumulation Fund for certain eligible employees who receive supplemental employer contributions after reaching the maximum of their salary schedule. At retirement, any ASAF balance is transferred to an annuity reserve and paid as an additional annuity component. A member should therefore separate the service pension calculation from any ASAF-related amount shown by TRS.
Tier VI FAS generally looks at five continuous years and limits salary spikes
For Tier VI, Final Average Salary is generally the highest average of wages earned during a continuous period for which the member received five years of service credit. The calculation has an anti-spiking rule: wages used for any year cannot exceed the average of the previous four years’ wages by more than 10%. Any amount over that 10% threshold is excluded from the FAS computation. This means the five largest calendar salaries are not automatically the five numbers TRS will average.
The distinction matters when late-career compensation changes sharply. A promotion, large differential, or unusual year of pensionable wages can raise FAS, but the 10% comparison can remove part of that increase for formula purposes. Members should also distinguish pensionable wages from take-home pay and from compensation that TRS excludes under plan rules. For an estimate, use the salary history TRS recognizes, test the five-year window, and apply the cap before multiplying by service credit.
A worked example shows why 20 years is a genuine formula breakpoint
Assume a Tier VI member has a final average salary of $100,000. At 18 years of Total Service Credit, the regular pension formula is 18 × 1⅔%, which is approximately 30% of FAS, or about $30,000 annually before any age reduction or other adjustment. At exactly 20 years, the published formula produces 35% of FAS, or $35,000. At 25 years, the first 20 years remain 35% and the next five add 10%, producing 45% of FAS.
Those numbers are illustrations, not benefit quotes. The actual retirement allowance can change because the FAS record differs, Total Service Credit includes fractions, an early-retirement factor applies, an outstanding loan affects the allowance, or an ASAF annuity is present. The example is still useful for one decision: it shows that comparing 19 years with 20 years should use the correct piece of the formula instead of continuing to multiply every year by 1⅔%. A TRS estimate should control the final decision.
Calculate the pension piece before applying any age reduction
The cleanest estimate starts with the service formula, not with the reduction table. For a $100,000 FAS, 15 years produces roughly $25,000 because 15 × 1⅔% is about 25%. Twenty years produces $35,000 because the Tier VI formula switches to 35% for the first 20 years. Thirty years produces 55% of FAS: 35% for the first 20 plus 20% for the next 10 years. Only after finding that unreduced formula amount should a member test whether an age reduction applies.
This order keeps two separate questions from being mixed together. The service formula determines the base regular pension. The retirement-age rules determine whether that amount is reduced. A 30-year member retiring at age 58 in 2026 may avoid an age reduction under Chapter 58, while a member with the same FAS and fewer years can face a large reduction at 58. Identical salaries therefore do not imply identical pensions; service credit and retirement age enter through different parts of the calculation.
| Total Service Credit | Formula before age reduction | Illustrative annual amount |
|---|---|---|
| 15 years | 15 × 1⅔% of FAS | About $25,000 |
| 20 years | 35% of FAS | $35,000 |
| 25 years | 35% + 5 × 2% | 45,000 |
| 30 years | 35% + 10 × 2% | $55,000 |
Test the five-year FAS window for excluded wage growth
A five-year average can look straightforward until one year jumps more than 10% above the average of the preceding four years. NYC TRS says the excess over that 10% level is excluded from Tier VI FAS. Suppose the previous four relevant annual wages average $90,000. The next year can contribute up to $99,000 to that comparison before the anti-spiking rule removes excess wages. A $108,000 actual wage year would therefore not simply enter the FAS at the full amount.
The rule does not mean every salary increase above 10% is ignored. It applies within the FAS calculation and compares a year with the average of the prior four years used for the test. That is why recreating FAS from a W-2 or a salary schedule can be unreliable. The member should compare TRS-recognized wages over candidate five-year periods, then use the system’s estimate when a promotion, retroactive payment, or other unusually large pensionable wage item appears near retirement.
Keep ASAF and loan effects outside the simplified service formula
NYC TRS describes an additional annuity component for members with an ASAF balance, and its plan materials also warn that outstanding QPP loans can reduce retirement benefits on an actuarial basis. Neither item should be hidden inside the simple “multiplier × FAS × service” estimate. A spreadsheet that matches the service formula can therefore still differ from the final allowance if it ignores account-specific annuity funds or an unpaid loan balance.
For a decision-grade estimate, label each component separately: regular pension from the Tier VI service formula, any age-reduction factor, ASAF-related annuity, and any loan-related reduction. This produces a much more useful reconciliation when the online estimate differs from a hand calculation. It also prevents a member from treating the illustrative formula as a guarantee. The official estimate and retirement calculation incorporate account facts that a generic formula cannot see.
Before you make a decision
- Pull the current TRS Total Service Credit and salary record.
- Calculate the regular pension with the under-20 or 20-plus formula as appropriate.
- Test the five-year FAS window for the 10% wage-growth exclusion.
- Apply any age-reduction factor only after computing the unreduced formula amount.
- Reconcile ASAF and outstanding-loan effects against the official TRS estimate.
Frequently asked questions
How is a NYC TRS Tier VI pension calculated?
For less than 20 years of Total Service Credit, the regular pension portion is 1⅔% of FAS for each year. At 20 years or more, the first 20 years provide 35% of FAS and each additional year adds 2% of FAS. Age reductions and account-specific adjustments can change the final payment.
What is Final Average Salary for NYC TRS Tier VI?
Tier VI FAS is generally the highest average of wages over a continuous period carrying five years of service credit. A wage year cannot exceed the average of the previous four years by more than 10% for FAS purposes; the excess is excluded from the calculation.
What percentage of salary does a Tier VI member get after 20 years?
At exactly 20 years of Total Service Credit, the Tier VI regular pension formula is 35% of Final Average Salary before any applicable early-retirement reduction or account-specific adjustment. For service beyond 20 years, each additional year adds 2% of FAS under the published formula.
What would 30 years of Tier VI service pay under the formula?
Thirty years produces 55% of FAS under the regular pension formula: 35% for the first 20 years plus 2% for each of the next 10 years. That is the pre-reduction formula amount. The member’s actual payment can differ because of retirement age, loan balances, ASAF funds, and other plan rules.
Does a late-career raise always increase NYC TRS FAS by the full amount?
No. Tier VI has a 10% anti-spiking rule within the five-year FAS calculation. If wages for a year exceed the average of the previous four years by more than 10%, the excess is excluded from FAS. Members with large late-career wage changes should use TRS-recognized salary records for estimates.
