CoastFIRE for Government Employees
By Minh · Updated 2026-04-25 · 5 min read
Government Employees have a specific CoastFIRE setup: typical incomes around $75,000, access to pension benefits, and primary tax-advantaged accounts in the TSP and FERS pension family. This guide walks through what those numbers look like and how the pension changes the math.
Federal employees (FERS) and most state workers have a defined-benefit pension on top of their TSP/457(b). Run your CoastFIRE number with the pension toggle on — it changes everything.

The table assumes your retirement spending is 60% of your current income (~$45,000/yr) and a 5% real return on investments.
Account Strategy for Government Employees
Government Employees typically have access to TSP and FERS pension. Here's the priority order most fee-only planners recommend:
- Employer match first — contribute enough to capture every match dollar. This is a guaranteed return that beats every other investment.
- Understand your pension vesting schedule — many pensions require 5–10 years of service before you're vested. Leaving early can forfeit huge amounts.
- Max a Roth IRA if eligible ($7,000/yr in 2026; $8,000 if 50+). Income limits: phase out at $150–165k single / $236–246k MFJ in 2026.
- Max your primary workplace plan ($23,500 in 2026 for TSP; $31,000 if 50+).
- HSA if eligible ($4,300 single / $8,550 family in 2026) — best tax-advantaged account in existence.
- Brokerage for everything beyond that — taxable, but flexible, no contribution limits, and LTCG rates (15% for most) are friendlier than ordinary income.
The Pension Math
A pension is mathematically equivalent to a bond paying you a guaranteed amount for life. To estimate its "lump sum equivalent":
Lump sum value ≈ annual pension × 25 (4% rule)
Example: a $36,000/year pension at retirement = a $900,000 portfolio equivalent.
That's why pension-eligible workers can hit CoastFIRE much earlier — half (or more) of your retirement income is already "saved" through your job. Run the calculator's pension toggle to see your specific number.
What Could Go Wrong
- Job change before vesting — losing your pension without vesting is the most expensive mistake on this page.
- Lifestyle inflation as income grows — a $30k raise can become $30k of extra spending if you're not intentional.
- Disability or income loss — own-occupation disability insurance is non-negotiable for government employees who depend on a specific skillset.
- Sequence-of-returns risk in early retirement — a 30% drop in year 1 of retirement can permanently impair your portfolio if you don't have a cash buffer.

Frequently Asked Questions
What's a realistic CoastFIRE number for government employees?
At a typical income of $75,000 and assuming 60% income replacement in retirement, the CoastFIRE number for a 35-year-old is approximately $260,300. The full table above shows other ages.
Should government employees prioritize TSP and or Roth IRA?
Capture employer match first (free money), then prioritize Roth IRA at lower incomes (under $100k single / $200k MFJ) for tax-free growth. Above those incomes, the deduction in a Traditional TSP usually wins. Mega-backdoor Roth (if available) is the gold-standard top-up.
How much does my pension change my CoastFIRE number?
A lot. Every $1,000/year of expected pension income lowers your portfolio target by about $25,000 (4% rule). A typical $30,000/yr pension reduces your CoastFIRE number by roughly $750,000.
What's the biggest CoastFIRE mistake for government employees?
Federal employees (FERS) and most state workers have a defined-benefit pension on top of their TSP/457(b). Run your CoastFIRE number with the pension toggle on — it changes everything.
