The private sector offer looks compelling on paper: a 30% salary increase, a 20-minute commute instead of two hours, and a modern workplace. But federal compensation is more than your base salary, and the decision to leave deserves a full accounting before you sign anything.
The Four Pillars of Federal Compensation
When comparing a federal position to a private sector offer, you need to evaluate all four components, not just base pay:
- Base salary including locality pay
- TSP with agency match (up to 5% of salary in free contributions)
- FEHB health insurance (government pays roughly 70-75% of premium)
- FERS pension (guaranteed, inflation-adjusted lifetime income)
How to Calculate What Your FERS Pension Is Worth
Your annual FERS annuity is calculated as:
1% x High-3 average salary x years of service
(1.1% if you retire at age 62 or older with 20+ years)
Example: 20 years of service, $90,000 High-3 average = $18,000 per year in annuity, guaranteed for life, with cost-of-living adjustments in retirement.
Over a 25-year retirement, that is $450,000 in guaranteed income at minimum, not counting COLA increases. That is what you walk away from when you leave early.
Every year you leave before your full retirement eligibility costs you 1% of your High-3 salary in annuity reduction, permanently.
The FEHB Value Most People Underestimate
The federal government pays approximately 70-75% of your FEHB premium. For a self-plus-one or family plan, the government contribution can be worth $10,000 to $15,000 or more per year.
When a private sector offer includes health insurance, compare the full premium cost, deductibles, copays, and out-of-pocket maximums, not just whether coverage exists.
The Commute Math
A two-hour round trip commute at 220 work days per year equals 440 hours annually, roughly 11 full work weeks, spent in your car. The economic value of reclaiming that time at even $30 per hour is over $13,000 per year. That is real and worth counting.
But time value alone does not close a gap created by walking away from a pension you spent 15 or 20 years building.
Questions to Answer Before You Decide
- How many years until your next full retirement eligibility milestone?
- What is the annual annuity difference between leaving now versus staying to your MRA+30?
- Does the private sector offer match or exceed your total federal compensation, including pension value?
- Does the new employer offer a 401(k) match? A pension? What are the vesting rules?
- How does the health insurance compare in total cost and coverage quality?
- What happens to your FEHB in retirement if you leave now versus staying to meet the five-year rule?
The Five-Year FEHB Rule
To carry FEHB coverage into retirement, you must have been enrolled in FEHB for the five consecutive years immediately before retirement. If you leave federal service before meeting this threshold and later return, the clock resets. Losing FEHB in retirement can cost tens of thousands of dollars in additional health insurance premiums.
The Bottom Line
Leaving federal service may absolutely be the right decision. The question is whether it is the right decision for your specific numbers at your specific point in your career. Run the math before you decide, not after.
