Could a Job Transfer Change Your FERS Pension Calculation?

A federal employee considering a transfer might look at the new salary, commute, and cost of living. There’s another number worth checking: your FERS pension calculation. A change in duty station, particularly late in your career, can affect the salary used to determine your retirement benefit.

The Difference Can Be Significant

Locality pay can create a substantial difference between federal employees in otherwise identical positions.

In 2026, locality adjustments range from 17.06% in the Rest of the U.S. to 46.34% in the San Jose-San Francisco-Oakland area. A GS-13, Step 5 employee in those two areas has a salary difference of more than $30,000.

But the important question isn’t simply where federal employees earn the most. It’s whether the move changes your high-3 average.

Your high-3 is based on your highest three consecutive years of basic pay. For most GS employees, applicable locality pay is included in that basic pay. That means a transfer to a different locality can potentially affect the salary figure used in your FERS pension calculation.

When a Transfer Can Help

Suppose you’ve spent most of your career in a lower-locality area but receive an opportunity to transfer to a higher-paying locality several years before retirement.

If those higher-paid years become part of your highest three consecutive years, they could increase your high-3 average.

That can translate into a larger pension because the FERS annuity formula applies a percentage to your high-3 average and years of creditable service.

The potential impact depends on your individual numbers. A $10,000 increase in the high-3 average, for example, produces a different annual pension increase depending on your years of service and which FERS multiplier applies.

For someone retiring under the standard 1% formula with 30 years of service, a $10,000 increase in the high-3 would mean roughly $3,000 more in annual starting pension income.

It Can Work the Other Way, Too

A transfer to a lower-locality area isn’t necessarily a problem. But if the lower salary is included in the three-year period that produces your highest average, it could reduce your eventual annuity.

And there’s an important detail to remember: your high-3 isn’t automatically your final three years.

It’s the highest average basic pay you earned during any three consecutive years. So an earlier period of higher earnings can remain your high-3 even after you’ve moved to a lower-paying position.

That’s an important part of the FERS pension calculation that can get overlooked when you’re evaluating a career move.

What About Moving After Retirement?

Your locality after retirement doesn’t change the pension you’ve already earned.

If you establish your high-3 while working in a higher-paying locality and later move somewhere less expensive after retirement, that move doesn’t recalculate your FERS annuity.

That makes the years immediately before retirement particularly important when you’re evaluating a transfer.

What This Means Before You Transfer

A higher locality doesn’t automatically make a transfer a good financial decision. Housing, commuting costs, taxes, and other expenses could offset some or all of the additional salary.

But your pension should be part of the calculation. Before accepting a new duty station, compare:

Current high-3 → projected high-3 → estimated pension difference → cost of making the move.

That gives you a much better picture of what the transfer could actually mean for retirement.
