How Federal Pension Benefits Are Calculated

Understanding how retirement benefits are computed helps you plan more effectively.

FERS Pension Formula Explained

Under FERS, the standard pension formula is:

1% × High-3 Average Salary × Years of Service

However, if you retire at age 62 or later with at least 20 years of service, the multiplier increases to:

1.1% × High-3 Average Salary × Years of Service

This enhanced multiplier can significantly increase your pension.

Example – FERS Standard Retirement

• Years of Service: 20
• High-3 Salary: $75,000
• Retirement Age: 60

Calculation:

$75,000 × 20 × 1% = $15,000 annually
Monthly Pension = $1,250

---

Example – FERS Enhanced Retirement (Age 62+)

• Years of Service: 25
• High-3 Salary: $90,000
• Retirement Age: 62

Calculation:

$90,000 × 25 × 1.1% = $24,750 annually
Monthly Pension = $2,062.50

The age 62 bonus increases lifetime income substantially.

---

CSRS Pension Formula Explained

CSRS uses a tiered percentage system:

• 1.5% for the first 5 years
• 1.75% for years 6–10
• 2% for every year beyond 10

Additionally, CSRS pensions are capped at 80% of your High-3 salary.

This cap is important and built into the calculator.

---

Example – CSRS Retirement

• Years of Service: 30
• High-3 Salary: $100,000

Calculation:

• First 5 years: 7.5%
• Next 5 years: 8.75%
• Remaining 20 years: 40%

Total: 56.25%

Annual Pension = $100,000 × 56.25%
= $56,250 annually
Monthly Pension = $4,687.50

If calculations exceed 80%, the pension is automatically limited to 80% of salary.

This is the average of your highest three consecutive years of basic pay.

Step 3: Enter Retirement Age

Your retirement age determines if you qualify for the enhanced FERS multiplier.

Step 4: Select Retirement System

Step 5: Click “Calculate”

The results will display:

• Annual Pension
• Monthly Pension
• Income Replacement Percentage

What Is Income Replacement?

Income replacement shows how much of your working salary your pension replaces.

For example:

If your High-3 salary is $80,000
And your annual pension is $24,000

Replacement ratio = 30%

Financial experts often recommend aiming for 70–80% total retirement income when combining pension, Social Security (if applicable), and personal savings.
