If you've searched "How do I calculate my FERS pension?", "What is High-3?", or "How much will my FERS retirement be?", you're asking one of the most important questions every federal employee faces.
Your Federal Employees Retirement System (FERS) pension is one of the most valuable retirement benefits you'll ever earn. But understanding how it's calculated, and how your retirement date can affect your monthly income, isn't always straightforward.
In this guide, we'll explain how the FERS pension is calculated, what your High-3 salary means, common mistakes to avoid, and why many federal employees benefit from reviewing their retirement strategy before they retire.
The Federal Employees Retirement System (FERS) is the retirement system that covers most civilian federal employees hired after 1983.
Your retirement income generally comes from three primary sources:
Together, these components are often referred to as the "three-legged stool" of federal retirement.
Your High-3 is the average of your highest-paid consecutive 36 months of basic pay.
This is one of the most important numbers used to calculate your pension.
Basic pay generally includes:
It generally does not include:
Because the High-3 is based on your highest consecutive three years, not necessarily your last three calendar years, it's important to know exactly which period produces the highest average salary.
For most federal employees, the pension formula is:
High-3 Salary × Years of Creditable Service × 1%
Example
Suppose you have:
Your estimated annual pension would be:
$100,000 × 30 × 1%
= $30,000 per year
or approximately
$2,500 per month before taxes and deductions.
When Does the 1.1% Multiplier Apply?
Some employees qualify for a larger pension calculation.
The formula becomes:
High-3 Salary × Years of Service × 1.1%
Generally, this applies if you:
Using the same example above:
High-3: $100,000
Years of Service: 30
Multiplier: 1.1%
Estimated pension:
$100,000 × 30 × 1.1%
= $33,000 annually
That's approximately $3,000 more every year compared to the standard formula.
What Counts Toward Years of Service?
Creditable service may include:
Your retirement eligibility and pension calculation depend on your specific employment history, so it's important to understand what service counts.
Common High-3 Mistakes
Many federal employees misunderstand how their pension is calculated.
Some common misconceptions include:
"My High-3 is simply my last three years."
Not always.
If an earlier three-year period had higher average earnings because of promotions or other factors, that period may actually produce your High-3.
"Working one more year always increases my pension."
Sometimes it does.
Sometimes the increase is smaller than expected.
The value of delaying retirement depends on several factors, including your salary growth, additional service credit, retirement eligibility, and personal retirement goals.
"My pension is my only retirement income."
For most FERS employees, your pension is only one part of your retirement income. Your TSP, Social Security, and personal savings also play important roles.
Multiply your High-3 average salary by your years of creditable service and the applicable multiplier (generally 1% or, in certain circumstances, 1.1%).
Your High-3 generally includes your highest consecutive 36 months of basic pay, including locality pay, but generally excludes overtime, bonuses, and awards.
Yes. Locality pay is generally included because it is considered part of your basic pay.
Potentially. Additional years of service, salary increases, and eligibility for the 1.1% multiplier can all affect your pension. The impact depends on your individual circumstances.
The Office of Personnel Management (OPM) provides retirement information and estimates, and many agencies offer retirement calculators. However, calculators may not account for every aspect of your personal retirement picture, which is why understanding how your benefits work together is important.
Calculating your FERS pension is an excellent place to start, but it isn't the whole retirement story.
Questions like these can have a significant impact on your retirement:
