Pensions FAQ & 101
Quick answers to the most common questions about public sector retirement. Every answer links to the full explanation.
What is a public pension?
A pension (also called a "defined benefit plan") is a guaranteed monthly payment for life after you retire from a government job. Unlike a 401(k), you don't manage investments or worry about running out of money — the amount is set by a formula based on your salary, years of service, and retirement age.
Most public pensions are constitutionally or statutorily protected, meaning they can't be reduced once earned.

How is my pension calculated?
Almost every public pension uses the same core formula:
Years of Service × Benefit Factor × Final Compensation = Annual Pension
The benefit factor (a percentage per year of service) increases with your retirement age. Final compensation is the average of your highest-earning consecutive months.

What is the benefit factor?
The benefit factor (or "age factor") is the percentage of your final salary you earn per year of service. It's the multiplier in the pension formula. The factor increases as you get older — retiring later means a higher percentage per year.
For example, CalPERS PEPRA 2% @ 62 gives you 1.0% per year at age 52, rising to 2.0% at 62, and maxing out at 2.5% at 67. With 30 years of service at age 62, that's 30 × 2.0% = 60% of your final salary.

What is final compensation?
Final compensation (also called "final average salary" or "highest average earnings") is the salary figure used in the pension formula. It's the average of your highest-earning consecutive period:
- CalPERS Classic: Highest 12 consecutive months
- CalPERS PEPRA: Highest 36 consecutive months
- CalSTRS: Highest 36 consecutive months (both Classic and PEPRA)
- NY (all tiers): Highest 3 consecutive years (with anti-spiking limits)
- FERS/CSRS: Highest 3 consecutive years ("High-3")
- TX TRS: Highest 3 consecutive years
- TX ERS: Highest 48 consecutive months (Group 4)
- FL FRS: Highest 5 years (post-2011) or 8 years (Average Final Compensation)
Anti-spiking rules in most systems prevent artificially inflating final salary through overtime or last-minute raises.

What's the difference between a pension and a 401(k)?
A pension guarantees a fixed monthly income for life based on a formula — you bear zero investment risk. A 401(k) is a savings account where you invest your own money — your retirement income depends on market performance, and you can run out.
Most private-sector workers only have a 401(k). Government workers get a pension plus access to a 457(b) (similar to a 401(k) but with no early withdrawal penalty).
Deep dive: Private vs Public comparison tool
Can I have a 401(k) or Roth IRA AND a pension?
Yes. A pension doesn't replace your other retirement accounts — it stacks on top of them. Most government workers have access to:
- A pension (guaranteed income for life — the foundation)
- A 457(b) (the government equivalent of a 401(k) — but better, see next question)
- A Roth or Traditional IRA (same $7,000/year limit as anyone else)
- Social Security (if your agency participates)
Federal employees get the TSP (Thrift Savings Plan) instead of a 457(b), with up to 5% employer matching. Some state/local workers can contribute to both a 457(b) and a 401(k)/403(b) simultaneously — double the tax-advantaged savings. The pension is the guaranteed floor; everything else is upside.
Deep dives: Private vs public comparison · Income stacking chart · Roth vs Traditional analysis · TSP details
What is a 457(b) plan?
The 457(b) is the government worker's secret weapon. It works like a 401(k) — pre-tax contributions, tax-deferred growth, same $23,500 annual limit (2026) — but with one critical advantage: no 10% early withdrawal penalty. Ever.
If you retire from government at age 55, you can immediately start pulling from your 457(b) penalty-free. A private-sector worker who retires at 55 and touches their 401(k) pays a 10% penalty on every dollar until age 59½. This makes the 457(b) the best bridge between early retirement and Social Security at 62.
The Projections tool shows exactly how different contribution rates affect your take-home pay now vs. retirement income later.

Do government workers keep health insurance in retirement?
In many states, yes — and the government keeps paying for most of it. But this varies enormously by state and is one of the biggest hidden factors in choosing where to work.
- California (CalPERS Health / PEMHCA): Nearly 1,200 agencies contract for CalPERS health. You stay in the same group plan at group rates, and your employer continues contributing toward your premium. Vesting: 5–10 years depending on hire date and agency. CalPERS is the second-largest public health purchaser in the nation.
- New York (NYSHIP): 1.2 million enrollees across 800+ local governments. Retirees pay the same rate as active employees. Employer contribution continues for life. Unused sick leave converts to a monthly premium credit.
- Federal (FEHB): Government pays ~72–75% of your health premium in retirement — the same share as when you were working. 5 years of continuous enrollment required. Widest plan selection in the country.
- Texas (GBP): Limited retiree health through the Group Benefits Program for state employees. ERS retirees with 10+ years get subsidized coverage, but benefits have been reduced over time. TRS-Care for teachers provides coverage but with rising premiums and reduced benefits.
- Florida (HIS): The Health Insurance Subsidy provides only $5 per month per year of service — at 30 years, that's just $150/month ($1,800/year). This is functionally negligible compared to actual health insurance costs.
In the private sector, employer health insurance almost always ends the day you leave. The gap between the best retiree health states (NY, Federal, CA) and the weakest (FL, TX) is worth $10,000–$25,000+ per year.

Is my pension guaranteed? Can they take it away?
The strength of your pension's legal protection varies dramatically by state — and this is something most workers never think about until it matters.
- California: The "California Rule" (CA Constitution, Article XVI, §17) protects all accrued pension benefits as a vested contractual right
- New York: NY Constitution, Article V, §7 — benefits "shall not be diminished or impaired"
- Illinois: Article XIII, §5 — strongest constitutional protection in America
- Federal: 5 U.S.C. §8348 — statutory contract rights protect FERS and CSRS annuities
- Florida: Contract-based protection — benefits for current employees generally can't be reduced retroactively, but the legislature has successfully frozen COLA and increased vesting requirements for new hires
- Texas: Benefits are classified as a "gratuity" — legally, the state views your pension as a gift, not an obligation. This is the weakest protection in America. Combined with no collective bargaining, Texas workers have essentially no legal recourse if the legislature changes the formula.

What if the stock market crashes before or during my retirement?
Your pension doesn't care. That's the whole point.
A pension is calculated from a formula — years of service, benefit factor, final salary. It has nothing to do with the stock market, account balances, or what the S&P 500 did last week. Whether the crash happens five years before you retire, the month you retire, or fifteen years into retirement, your pension check is the same.
A 401(k) has no such protection. Here's what happens to a 401(k) in each scenario:
- Crash before retirement: Your balance drops 30–40% right when it's at its largest. You either retire with drastically less income or delay retirement for years waiting to recover. This is called "sequence of returns risk" — when the loss happens matters as much as how big it is.
- Crash during retirement: You're withdrawing from a shrinking balance. The combination of market losses and ongoing withdrawals can create a death spiral where the account depletes years ahead of schedule. A 2008-style crash in year 3 of a 401(k) retirement can mean running out of money by age 80.
The pension pays the same amount through all of it — and it's constitutionally protected. PenPublic's tools let you simulate real historical crashes (2008, dot-com, COVID, 1973) and see the impact side by side.

Can I get Social Security AND a pension?
Yes — and since January 2025, with no penalty. It depends on whether your employer participates in Social Security:
- Most CalPERS agencies, all NY systems, all FERS employees: You pay into Social Security and receive both your full pension and full Social Security.
- CalSTRS, some CalPERS agencies, CSRS: These positions don't participate in Social Security — but if you earned Social Security credits from other work, you now get your full benefit thanks to the WEP/GPO repeal.
- Texas TRS: Teachers do NOT participate in Social Security. TRS is the pension and that's it — no SS stacking.
- Florida FRS: All FRS members participate in Social Security. Pension + SS stack together.
Deep dives: CA Social Security & WEP/GPO · NY Social Security · Federal WEP/GPO · TX Social Security · FL Social Security
What is the WEP/GPO repeal?
The Social Security Fairness Act (P.L. 118-273), signed January 5, 2025, permanently repealed two provisions that had reduced Social Security benefits for public workers since the late 1970s/early 1980s:
- WEP (Windfall Elimination Provision): Reduced your own Social Security retirement benefit if you also received a government pension from non-SS-covered employment
- GPO (Government Pension Offset): Reduced or eliminated Social Security spousal/survivor benefits by two-thirds of your government pension
The repeal affected 3.2 million beneficiaries. SSA distributed $17 billion in retroactive payments by mid-2025. California had more affected workers than any other state.

How are Texas and Florida different from California, New York, and D.C.?
This is one of the most important questions for anyone deciding where to build a public sector career. The five states PenPublic covers represent two very different pension philosophies:
California, New York, and D.C./Federal offer what we call the "full protection" model: higher multipliers, automatic COLA, constitutional or strong legal protections, and substantial retiree health benefits. The trade-off is higher cost of living and (in CA/NY) higher state income taxes.
Texas and Florida offer what we call the "lean benefit" model: decent multipliers on paper, but no automatic COLA, weaker legal protections, and minimal retiree health. The trade-off is no state income tax and lower cost of living.
Here's how the five compare on the factors that matter most:
| California | New York | D.C./Federal | Texas | Florida | |
|---|---|---|---|---|---|
| Multiplier | 2.0–3.0% | 1.67–2.0% | 1.0–1.7% | 2.0–2.3% | 1.6–3.0% |
| COLA | CPI (2% cap) | 1–1.5% fixed | CPI (partial) | None | None (frozen) |
| Legal protection | California Rule | Constitutional | Federal statute | Gratuity | Contract |
| Retiree health | PEMHCA | NYSHIP | FEHB | Limited | $5/mo/yr |
| Collective bargaining | Yes | Yes (Taylor Law) | Yes (FLRA) | No | Limited |
| State income tax | 9.3–13.3% | 4–10.9% | 4–10.75% (DC) | None | None |
| SS participation | Partial | Yes | Yes (FERS) | Partial | Yes |
The critical difference is COLA. A Texas teacher who retires at $60,000/year will still receive $60,000/year 20 years later — but that $60,000 only buys about $33,000 worth of goods after 3% annual inflation. A California retiree at the same starting pension would be receiving roughly $89,000/year after 20 years of 2% compounding COLA. Over a 25-year retirement, the COLA difference alone is worth $400,000+.
The second critical difference is legal protection. California's "California Rule" and New York's constitutional clause make it essentially impossible to reduce your benefits once hired. Texas's "gratuity" classification means the legislature can theoretically change the formula at any time. Florida successfully froze COLA for all members in 2011 — something that would be unconstitutional in IL, NY, or AZ.
The no-income-tax advantage of TX and FL is real — a California retiree loses 6–9% of their pension to state tax. But the COLA gap and retiree health gap typically dwarf the tax savings over a full retirement.

Am I Classic or PEPRA?
California only. If you were first hired by a CalPERS or CalSTRS employer on or after January 1, 2013 and had no prior California public pension membership or reciprocity, you're PEPRA. If you were hired before that date and maintained continuous membership, you're Classic.
PEPRA members have lower benefit factors, higher minimum retirement ages, 36-month final compensation averaging, and a pensionable salary cap. Classic members generally have richer formulas.
Deep dives: PEPRA reform details · Classic vs PEPRA formulas · Who is a "new member"
What is COLA?
COLA (Cost-of-Living Adjustment) is the annual increase applied to your pension after retirement to help keep up with inflation. The rules vary significantly:
- CalPERS: 2% compounding (most contracts). Unused inflation accumulates in a "COLA Bank"
- CalSTRS: 2% simple (non-compounding), with an 85% purchasing power floor
- NY (ERS/PFRS): 50% of CPI on the first $18,000 of pension (for 5+ year retirees with 20+ years of service)
- FERS: CPI minus 1% when inflation exceeds 2% ("Diet COLA")
- CSRS: Full CPI adjustment
- Texas (TRS/ERS): No automatic COLA. Requires legislative action (ad hoc). Some retirees have gone over a decade without any adjustment.
- Florida (FRS): COLA frozen since 2011. The 3% annual COLA was eliminated by SB 2100. All retirees since 2011 receive zero inflation protection.
The difference between having COLA and not having it is massive. See the rankings methodology for a table showing how a $60,000 pension with 3% COLA pays out $687,000 more over 25 years than the same pension with no COLA.

When can I retire?
It depends on your system:
- CalPERS PEPRA (misc): age 52 minimum, optimal at 62+
- CalPERS Classic (2% @ 55): age 50 minimum
- CalPERS Safety (PEPRA): age 50 minimum, optimal at 57
- CalSTRS: age 55 minimum (both Classic and PEPRA)
- NY ERS Tier 6: age 55 (with reduction) or 63 (full benefit)
- NY PFRS: after 20–25 years of service regardless of age
- FERS: MRA (55–57) with 30 years, age 60 with 20 years, or age 62 with 5 years
- CSRS: age 55 with 30 years, or age 62 with 5 years
- TX TRS: Rule of 80 (age + years = 80), or age 62 with 5 years
- TX ERS (Group 4): age 65 with 10 years, or Rule of 80
- FL FRS (post-2011): age 65 with 8 years, or 33 years regardless of age
- FL FRS Special Risk: age 60 with 8 years, or 25 years regardless of age
Retiring before your system's optimal age means a permanently lower benefit factor.

What happens if I leave before I'm vested?
Most systems require 5 years of service to vest (become eligible for a future pension). If you leave before vesting, you can withdraw your employee contributions (usually with interest), but you forfeit the employer-funded pension benefit.
Notable differences:
- Florida FRS: 8-year vesting (post-2011) — among the longest in the country
- New York Tier 6: 10-year vesting
- Texas TRS: 5-year vesting
If you leave after vesting but before retirement age, you have a "deferred" pension — you'll receive payments when you reach the eligible retirement age, based on the salary and years you had when you left.

What is the PEPRA salary cap?
California only. PEPRA limits how much of your salary can be used in the pension formula. For 2026:
- $159,733 — if your agency participates in Social Security
- $191,679 — if your agency does NOT participate in Social Security
Salary above this cap doesn't count toward your pension. If you earn more than the cap, the excess should go into a 457(b) or IRA.
Deep dives: PEPRA provisions · Salary cap in the calculator
What are the contribution rates?
This is what you and your employer each pay into the pension system:
California (CalPERS PEPRA misc): Employees pay roughly 8% of salary; employers pay 25–30%+. PEPRA requires employees to pay at least 50% of normal cost.
New York (ERS Tier 6): Employees pay 3–6% of salary (sliding scale based on earnings); employers pay 10–15%+.
Federal (FERS): Most employees pay 4.4% of salary; agencies pay the pension contribution plus 6.2% Social Security plus up to 5% TSP match — total employer retirement contribution is roughly 25–30%.
Texas (TRS): Employees pay 8.25% of salary; state contributes 9.0%. Texas (ERS): Employees pay 9.5% of salary; state contributes 9.5%.
Florida (FRS): Employees pay 3% of salary; employers pay the balance (varies by membership class, roughly 11–27%).

What is reciprocity?
California only. Reciprocity is an agreement between California public pension systems that protects your benefits when you move between participating employers. If you leave one CalPERS agency and join a CalSTRS employer (or a 1937 Act county system), reciprocity lets you:
- Use your highest salary from any reciprocal employer in the pension formula
- Combine service credit for retirement eligibility (though benefits are calculated separately)
- Avoid a break in service that would make you a "new member" under PEPRA
You must establish reciprocity within the required window (typically starting the new job within 6 months of leaving the old one).

What are New York's pension tiers?
New York assigns members to tiers based on when they joined:
| Tier | Joined | Key Features |
|---|---|---|
| 1 | Before 7/1/1973 | Non-contributory, most generous |
| 2 | 7/1/1973 – 7/26/1976 | Non-contributory after 10 years |
| 3 | 7/27/1976 – 8/31/1983 | 3% employee contribution |
| 4 | 9/1/1983 – 12/31/2009 | 3% for 10 years, then 0% |
| 5 | 1/1/2010 – 3/31/2012 | 3% for entire career |
| 6 | 4/1/2012 – present | 3–6% sliding scale, age 63 for full benefit |
The "Fix Tier 6" movement seeks to restore Tier 4-level benefits for Tier 6 members.

What is FERS vs CSRS?
These are the two federal retirement systems:
- FERS (Federal Employees Retirement System) — covers employees hired after 1983. A "three-legged stool": pension + Social Security + TSP (the federal 401k). Lower pension benefit factors (1–1.1% per year) but supplemented by SS and TSP.
- CSRS (Civil Service Retirement System) — covers employees hired before 1984 (now ~2% of the workforce). Standalone pension with higher factors (1.5–2% per year). No Social Security, no TSP employer matching.
All new federal employees are under FERS.
Deep dives: FERS overview · CSRS overview · FERS formulas · CSRS formulas
What is the TSP?
The Thrift Savings Plan is the federal government's retirement savings plan — essentially a 401(k) for federal employees and military members. Key features:
- FERS employees receive automatic 1% agency contribution plus up to 4% matching (5% total employer contribution)
- CSRS employees can contribute but receive no matching
- Five core index funds (G, F, C, S, I) plus lifecycle (L) funds
- Same contribution limits as a 401(k) ($23,500 in 2026, plus $7,500 catch-up at 50+)
The TSP has some of the lowest expense ratios of any retirement plan in the country.

What is Florida's DB/DC choice?
Florida only. FRS is unique among major states in giving every new employee a genuine choice between two retirement plans:
- Pension Plan (DB): Traditional defined benefit — 1.6% multiplier for Regular Class, 3.0% for Special Risk. Guaranteed income for life.
- Investment Plan (DC): Employer contributes a percentage of salary to your individual account. You manage the investments and bear the market risk.
Employees have an initial enrollment period to choose. If they don't actively elect, they default into the Investment Plan — a design choice that pension advocates argue steers workers away from the better long-term deal. Once you've been in a plan for 5+ years, switching becomes costly.

What is DROP?
Florida and some other states. DROP (Deferred Retirement Option Program) lets eligible employees "retire in place." Your pension payments accumulate in a DROP account earning guaranteed interest while you continue working and earning salary. After up to 60 months, you leave with a lump sum AND your full pension.
A Florida Special Risk employee entering DROP at 55 with a $75,000/year pension can accumulate $375,000+ over 5 years — then leave with the lump sum and collect the pension for life.

How do California, New York, Federal, Texas, and Florida pensions compare?
Each system has different strengths:
| California | New York | Federal (FERS) | Texas | Florida | |
|---|---|---|---|---|---|
| Best factor | 2.5% @ 67 (PEPRA) or 3% @ 60 (Classic) | 1.67–2% (by tier) | 1.1% (age 62+, 20 yrs) | 2.3% (TRS) | 3.0% (Special Risk) |
| SS included? | Varies by agency | Yes (all systems) | Yes | Partial | Yes |
| COLA | 2% compounding | ~50% of CPI on $18k | CPI minus 1% | None (ad hoc) | None (frozen) |
| Protection | California Rule | Constitutional | Statutory | Gratuity | Contract |
| 457(b) / TSP | 457(b) available | 457(b) available | TSP with 5% match | 457(b) available | 457(b) available |

| Power Ranking | #2 (S-Tier) | #10 (A-Tier) | #19 (B-Tier) | #31 (C-Tier) | #32 (C-Tier) |
California has the richest formulas, New York has the broadest SS integration and best retiree health, Federal has the best employer-matched savings (TSP), and Texas and Florida have no state income tax but significantly weaker COLA and retiree health.

Should I choose Roth or Traditional IRA?
It depends on your tax rates now vs. in retirement:
- Traditional IRA: Tax deduction now, taxed on withdrawal. Better when your current tax rate is higher than your expected retirement tax rate.
- Roth IRA: No deduction now, tax-free withdrawal. Better when your retirement tax rate will be equal to or higher than your current rate.
Government workers with pensions often have substantial retirement income (pension + SS), which can keep their retirement tax bracket higher than expected — making Roth more attractive than many assume.
Deep dive: Roth vs Traditional IRA analysis tool
What is the healthcare gap?
If you retire before age 65, you have a gap between your retirement date and Medicare eligibility. For workers without retiree health coverage, this means buying individual insurance at full cost — $800–2,000+/month.
The good news: if your agency contracts for CalPERS Health, NYSHIP, or you qualify for FEHB, your employer coverage continues into retirement and bridges this gap automatically. This is why retiree health eligibility is one of the most important factors when evaluating a government job.
For workers in Texas or Florida — where retiree health is minimal — this gap is a significant out-of-pocket expense. Options include COBRA (18 months), ACA marketplace plans (possibly with subsidies), or spousal coverage.
