Coast FIRE Calculator for Government Employees
Government retirement benefits can depend on the retirement system, service history and when benefits begin. Enter your actual pension and retirement-plan estimates to compare public-service timelines without relying on a generic government pension formula.
Your Government Coast FIRE Plan
Your Government Employee Coast FIRE Position
At age 60, planned spending of $60,000/yr is offset by your $24,000/yr pension starting at age 60. Your net portfolio requirement is $900,000. With compound growth over 25 years, $355,411 invested today reaches that target with zero further contributions after exit.

What Changes If You Stay to Another Service Date?
Service Date ScenariosCompare up to 3 official pension estimates, exit ages, and pre-exit contribution periods without automated formula guesses.
Years Between Government Work and Pension Income
Exit-to-Pension GapModel optional bridge work income and cash flow during the 10-year period between exiting public service (Age 50) and pension commencement (Age 60).
Is This Government Job Covered by Social Security?
SSA notes state and local workers may have Social Security only, a public pension only, or both.
Why Use a Government Employee Coast FIRE Calculator?
Leaving public service, starting a pension and fully retiring can happen on different dates. Government employees may also have a pension alongside TSP, 457(b), 403(b) or other investments. This calculator keeps those pieces separate so a future pension is not treated as money already available today.
Leaving Government and Starting a Pension Are Different Dates
A public employee may leave government years before a pension begins. Modeling those dates separately prevents future pension income from reducing the portfolio requirement during years when that income is not yet available.
Government Retirement Systems Are Not One Standard Benefit
Federal, state and local employers use different retirement systems. Pension eligibility, Social Security coverage and retirement-account availability can differ, so this calculator relies on the benefit estimates and plan information you enter.
Frequently Asked Questions
Neutral answers to common government pension, TSP, and public sector Coast FIRE questions.
How do I calculate Coast FIRE if I leave government years before my pension starts?
Enter the government-exit date and pension start date separately. The calculator should not apply pension income during the intervening years and should use only the pension estimate associated with that exit scenario.
What pension amount should I use if my current estimate assumes I keep working for many more years?
Use the official benefit estimate corresponding to the employment scenario being tested. A projected benefit based on future service should not automatically be used in a scenario where that future service does not occur.
How should I model TSP, 457(b) or 403(b) balances alongside a government pension?
Keep investment-account balances separate from pension income. Eligible investment balances can be included in the retirement portfolio, while recurring pension payments are modeled as income beginning at their stated start age.
What if I leave federal service before qualifying for an immediate FERS retirement?
Enter the deferred or postponed benefit estimate and commencement age provided by your official retirement resources. The calculator should model those values without determining your personal FERS eligibility.
Do all state and local government employees have both a pension and Social Security?
No universal assumption should be made. SSA states state and local workers may have Social Security coverage, a public pension, or both. Use your pay records, retirement system and SSA record.
How do I compare staying another few years for a larger government pension?
Create separate exit scenarios using the official pension estimate for each date and the contributions expected before that date. The calculator can show the resulting Coast projections without ranking one employment choice over another.
What if leaving government changes my retiree health-benefit eligibility?
Keep health-benefit eligibility outside the Coast calculation until verified with the applicable employer or retirement authority. Enter the healthcare cost expected under each scenario and use the dedicated healthcare calculator for detailed cost modeling.
