If you work for the U.S. government, the U.S. Postal Service, the VA, a county hospital, Kaiser, or virtually any other public-sector or healthcare employer, your retirement plan is not a 401(k). It's a pension (FERS, CSRS, LACERA, or a hospital plan) stacked with a Thrift Savings Plan or 403(b), and often Social Security on top. Each component has rules most private-sector advisors never touch. We do.
Almost every client in this category falls into one of these four retirement systems. The first step is knowing which one covers you — then optimizing the supplemental savings, the survivor election, and the tax picture.
Federal Employees Retirement System. All federal hires on/after Jan 1 1984, including USPS. Three-component: Basic Benefit pension + Social Security + TSP (Thrift Savings Plan) with agency match up to 5%.
Civil Service Retirement System. Federal hires before 1984 still on the old system. Richer pension (about 1.5–2% per year of service), NO Social Security through federal work, and a TSP with no match.
County-hospital nurses and staff covered by a county system like LACERA, OCERS, or the University of California plan (UCRP). Same age-factor × service × final-comp formula as other county systems.
Kaiser Permanente employees, non-profit hospital systems, and private hospital groups. Typically a pension (Kaiser Permanente Retirement Plan) plus a 403(b) / 401(k) — with Social Security through normal FICA.
FERS covers about 2.8 million federal workers, including postal employees, VA staff, and most civilian agencies. Your pension is one of three legs; the TSP is how you close the income gap and build real wealth.
The FERS monthly pension formula (Basic Benefit):
High-3. The average of your highest three consecutive years of basic pay.
Multiplier. 1% per year of service in most cases — bumps to 1.1% if you retire at 62 or older WITH 20+ years of service.
MRA. Minimum Retirement Age ranges from 55 to 57 depending on birth year.
| Retirement Scenario | Multiplier |
|---|---|
| Age 62+ with 20+ yrs | 1.10% |
| Age 62+ with < 20 yrs | 1.00% |
| Age 60+ with 20+ yrs | 1.00% |
| MRA+30 years | 1.00% |
| MRA+10 (reduced) | 1.00% − 5%/yr under 62 |
Special provisions apply to law enforcement, firefighters, air traffic controllers, and certain USPS safety categories.
| Born | MRA |
|---|---|
| Before 1948 | 55 y 0 m |
| 1953–1964 | 56 y 0 m |
| 1965–1969 | 56 y 8 m |
| 1970+ | 57 y 0 m |
MRA matters because it sets the earliest date you can retire under MRA+30, MRA+20, or MRA+10 rules.
Worked example. FERS employee retires at age 62 with 30 years of service, High-3 of $92,000:
Add FERS Social Security (roughly $2,400/mo at 62) and a well-funded TSP (say $400K producing $1,400/mo at 4% SWR) and you're at $6,330/mo gross — a replacement rate near 82% of High-3. The TSP is what makes that math work. Without it you're at 55%.
CSRS covers federal hires before 1984 who didn't elect to switch. The pension is much larger per year of service, but there is no Social Security from federal work, and anyone who earned Social Security elsewhere gets hit by the WEP (Windfall Elimination Provision) or GPO (Government Pension Offset) — a common planning pitfall.
CSRS monthly pension formula:
A 35-year CSRS career produces roughly a 66.25% replacement rate on High-3 — significantly higher than FERS — but the retiree must solve the Social Security picture and plan for the survivor benefit separately.
Special note: CSRS Offset covers a small group re-hired between 1984–1987 who have both a CSRS pension and Social Security. The pension is reduced by roughly the Social Security amount earned during that offset service. We see this in a handful of VA and postal clients and the accounting is specific.
The Thrift Savings Plan is the federal 401(k). It has the lowest fund expenses of any major retirement plan (often under 5 basis points). Most federal and postal workers under-contribute, leave the agency match on the table, or let the money sit in the wrong fund. Fixing those three levers alone can swing a retirement by six figures.
| Category | Limit |
|---|---|
| Employee contribution | $24,500 |
| Age 50+ catch-up | +$8,000 |
| Age 60–63 super catch-up | +$11,250 |
| Agency automatic (FERS) | 1% of salary |
| Agency match (first 5%) | +4% match |
To capture the full 5% match you must contribute at least 5% of salary yourself. Many FERS employees miss this.
| G Fund | Govt securities, no NAV risk |
| F Fund | Bloomberg Agg bonds |
| C Fund | S&P 500 |
| S Fund | US small/mid cap |
| I Fund | International developed |
| L Funds | Target-date lifecycle |
Roth TSP is available alongside the traditional pre-tax. Most FERS employees should blend both.
USPS employees are federal employees — they retire under FERS (or CSRS for pre-1984 hires). The rules are the same as any other federal agency, but the retirement path has a few Postal-specific wrinkles worth knowing before you file papers.
Early-out windows
The Postal Service periodically offers Voluntary Early Retirement Authority and Voluntary Separation Incentive Payments. Rules, penalty waivers, and lump-sum amounts change case by case — run the numbers before accepting.
Post-2025 health system
Retiree healthcare for USPS moved out of FEHB into the separate PSHB program. Medicare Part B enrollment rules and the PSHB premium structure now drive the retiree health decision at age 65.
FERS bridge to 62
If you retire under MRA+30 or at 60+ with 20+ years, FERS pays a monthly Special Retirement Supplement roughly equal to your Social Security benefit earned to that point — until age 62.
Pension Max opportunity
Federal and postal retirees choose between a full, partial, or no survivor annuity. The spousal consent rules are strict. Pension Maximization can often replace the survivor election with life insurance at a lower total cost.
"Nurse retirement" is not one thing — it depends entirely on the employer. A VA nurse is on FERS. A Kaiser nurse is on the Kaiser Permanente plan. A county-hospital nurse is on LACERA. A teaching-hospital nurse is on CalPERS. Knowing which plan you have is the first step.
FERS + TSP
Department of Veterans Affairs nurses and federal hospital nurses are federal employees. FERS pension + Social Security + TSP. Same math as any other FERS employee.
Cash Balance Pension + 401(k)
Kaiser's Retirement Plan is a cash-balance formula that grows with pay credits and interest credits, supplemented by a 401(k)/403(b). Union contracts (SEIU, CNA) set the pay-credit rate.
Plan D / Plan E / Plan G
Los Angeles County hospital nurses retire under LACERA General tiers — Plan E is contributory, Plan D is the older non-contributory legacy, Plan G is post-2013 PEPRA. Same age-factor system as other LACERA members.
University of California Retirement Plan
UCLA Health, UCSF, UCSD, and other UC hospital nurses retire under UCRP. Pension + DC Plan + 403(b) + 457(b). Generous formula, but the pension start date matters.
2% at 55 / 2% at 62
Many California municipal and district hospitals contract with CalPERS for the pension. Same age-factor schedules as CalPERS General.
403(b) or 401(k)
For-profit hospital systems (HCA, Tenet, Sutter, etc.) typically run a 403(b) or 401(k) with a company match, no pension. Your retirement math becomes standard DC-plan math — contributions, match, investment selection.
If you're FERS and contribute less than 5%, you're giving up free money every paycheck. The first 5% from the agency compounds the same as your own money — and you've already "paid" for it with tax dollars.
G Fund never loses value — and barely grows. A 30-year-old with a FERS career ahead should not have 100% in G Fund. We see this constantly, especially among postal clients.
If you have any Social Security earned outside your federal job (second career, spouse), the Windfall Elimination Provision can slash what you'd otherwise get. CSRS retirees are hit hardest.
Electing the maximum survivor benefit costs you ~10% of your pension for life. In some marriages the math says to elect it — but in many, Pension Maximization via life insurance wins. Run both.
Many FERS retirees under 62 don't realize they qualify for the monthly Special Supplement, which fills the gap until Social Security kicks in. Confirm eligibility before retiring or you may leave 2–5 years of bridge income unclaimed.
TSP's low fees are hard to beat. Rolling to an IRA at retirement isn't automatic gospel — sometimes it costs you basis points forever. We evaluate the rollover math before we recommend it.
FERS, CSRS, CSRS Offset, LACERA Plan E, UCRP, Kaiser — each has different calculators. We start by confirming exactly which plan covers your service.
We model your pension at MRA, age 60, and age 62 (or similar) — so you can see the cost of leaving early vs. the benefit of staying longer.
Pension + Social Security + Special Supplement rarely cover 100% of your pre-retirement income. We calculate what the TSP / 403(b) / 457(b) must produce.
We reallocate across G / F / C / S / I / L funds based on your time horizon and risk profile. And we make sure you're capturing the full agency match.
Max survivor vs. partial vs. none — compared with life-insurance-based Pension Maximization. We run the math under realistic mortality assumptions for both spouses.
If you're CSRS or have a non-federal Social Security record, we model the WEP/GPO hit and design withdrawals around it — Roth TSP, basis rules, and state-tax considerations included.
Send us your most recent TSP statement, your FERS annuity estimate, or your Kaiser/LACERA/UCRP benefit summary. We'll run your retirement projection at multiple ages and show you the exact dollar gap your supplemental savings must close.
