Federal Employee Pension Calculator
Planning your federal retirement requires clarity, accuracy, and realistic projections. Whether you are covered under the Federal Employees Retirement System (FERS), Civil Service Retirement System (CSRS), FERS-RAE, FERS-FRAE, or Special category retirement (law enforcement/firefighter), understanding your projected pension is essential for long-term financial security.
Our Federal Employee Pension Calculator is an advanced retirement estimation tool designed to help U.S. government employees calculate:
- Gross annual pension
- Net annual pension (after survivor reduction)
- Monthly pension payment
- Total creditable service (including unused sick leave)
- Income replacement rate
- 30-year lifetime pension estimate (inflation-adjusted)
This guide explains how the calculator works, how to use it correctly, and how to maximize your federal pension benefits.
What Is a Federal Employee Pension?
A federal pension (also called an annuity) is a lifetime retirement benefit paid to eligible U.S. federal employees. It is primarily based on:
- High-3 average salary
- Total creditable service
- Retirement system
- Age at retirement
- Survivor benefit election
- Inflation (COLA) adjustments
Unlike private-sector retirement plans that depend heavily on market performance, federal pensions provide predictable income for life.
Retirement Systems Supported in This Calculator
This tool supports multiple federal retirement systems:
1. FERS (Regular)
- 1% multiplier per year of service
- 1.1% if retiring at age 62 or older with 20+ years
2. FERS-RAE (Revised Annuity Employees)
Same benefit formula as FERS but with higher employee contributions.
3. FERS-FRAE (Further Revised Annuity Employees)
Same calculation structure as FERS, different contribution rates.
4. FERS Special (Law Enforcement / Firefighter)
- 1.7% per year for first 20 years
- 1% for service beyond 20 years
5. CSRS
- 1.5% for first 5 years
- 1.75% for next 5 years
- 2% for service beyond 10 years
The calculator automatically applies the correct multiplier formula based on your selected system.
Key Inputs Explained
1. Total Years of Service
Enter your full creditable federal service. Decimals are allowed.
2. High-3 Average Salary
Your High-3 is the average of your highest three consecutive years of base pay. This figure forms the foundation of your pension.
3. Current Age & Planned Retirement Age
While current age is useful for planning, the planned retirement age determines whether you qualify for enhanced multipliers (such as the 1.1% FERS rule at age 62+ with 20+ years).
4. Unused Sick Leave (Major Benefit)
Unused sick leave increases your pension calculation (but not eligibility).
Conversion formula:
2,087 hours = 1 year of service
The calculator automatically converts sick leave into additional creditable service years.
Example:
1,043 hours ≈ 0.5 years added to service.
This can increase lifetime pension by thousands of dollars.
5. Survivor Benefit Election
You may choose:
- Full Survivor Benefit (reduces pension by 10%)
- Partial Survivor Benefit (reduces pension by 5%)
- No Survivor Benefit (no reduction)
The calculator displays both gross and net annual pension so you can clearly see the financial difference.
6. Inflation Rate (COLA)
You can select:
- 1.5%
- 2%
- 2.5%
- 3%
- No adjustment
The calculator compounds your net pension annually over 30 years to provide a long-term lifetime estimate.

Example Calculation
Let’s walk through a realistic scenario:
- 30 years of service
- 1,500 unused sick leave hours
- $125,000 High-3 salary
- FERS system
- Planned retirement at age 62
- Partial survivor benefit
- 2.5% inflation
Step 1: Sick Leave Conversion
1,500 ÷ 2,087 = 0.72 years
Creditable Service = 30.72 years
Step 2: Multiplier
Age 62 + 20+ years → 1.1%
Step 3: Gross Annual Pension
$125,000 × 30.72 × 1.1%
≈ $42,240
Step 4: Survivor Reduction (5%)
Net Annual ≈ $40,128
Monthly Pension
≈ $3,344 per month
30-Year Lifetime Estimate (2.5% inflation)
Significantly higher due to compounding adjustments.
This demonstrates how retirement age and sick leave meaningfully increase total pension value.
What Is Income Replacement Rate?
Replacement rate shows how much of your working salary your pension replaces.
Formula:
(Net Annual Pension ÷ High-3 Salary) × 100
If your High-3 is $125,000 and net pension is $40,000:
Replacement Rate = 32%
Many retirement planners recommend targeting 70–80% total income replacement when combining:
- Federal pension
- Social Security (if applicable)
- Thrift Savings Plan withdrawals
- Other investments
