Fers Lump Sum Calculator
If you’re a federal employee planning for retirement, understanding your financial future is essential. One of the key components of that future is your Federal Employees Retirement System (FERS) benefits. These include a monthly annuity and the potential value of your pension as a lump sum. To help federal employees navigate this complex retirement landscape, we’ve created the FERS Lump Sum Calculator — a user-friendly tool that provides a clear estimate of your retirement income.
In this article, we’ll walk you through how to use the calculator, show real-world examples, and answer the most common questions about FERS retirement planning.
What Is the FERS Lump Sum Calculator?
The FERS Lump Sum Calculator is a free online tool designed to estimate two major retirement metrics for federal employees:
- Monthly Annuity – Your expected monthly pension based on service and salary.
- Lump Sum Equivalent – The estimated present value of your annuity over your life expectancy, useful for financial planning.
These projections are based on your high-3 average salary, years of federal service, retirement age, and retirement type (regular, early, deferred, or disability). With just a few inputs, you can get an instant estimate tailored to your situation.
How to Use the FERS Lump Sum Calculator (Step-by-Step)
Here’s a step-by-step guide to using the tool effectively:
1. Enter Your High-3 Average Salary
This is the average of your highest-paid consecutive 3 years of federal service.
- Example: If your highest 3-year average salary was $85,000, enter 85000.
2. Enter Your Years of Federal Service
Include all creditable federal service time.
- Example: For 22.5 years of service, enter 22.5.
3. Enter Your Age at Retirement
Your age helps calculate both reductions and your life expectancy.
- Example: If you plan to retire at 62, enter 62.
4. Select Your Retirement Type
Choose from:
- Regular Retirement
- Early Retirement
- Deferred Retirement
- Disability Retirement
Each type affects your annuity differently.
5. Click “Calculate”
The calculator will process your inputs and return:
- Estimated Monthly Annuity
- Estimated Lump Sum Value (present value of annuity over life expectancy)
Example Calculation
Let’s walk through a practical example:
- High-3 Salary: $90,000
- Years of Service: 25
- Age at Retirement: 63
- Retirement Type: Regular Retirement
Result:
- Monthly Annuity: ~$2,063.00
- Lump Sum Value: ~$351,000 (based on current assumptions)
These estimates help you plan for retirement and compare income with Social Security, Thrift Savings Plan (TSP) withdrawals, and other retirement resources.

Additional Insights into FERS Retirement
- High-3 Salary: This is not necessarily your final salary. It’s an average of your highest-paid consecutive 3 years.
- Annuity Percentage: Under FERS, it’s generally 1% of your high-3 salary per year of service. If you retire at 62+ with 20+ years, that jumps to 1.1%.
- COLA Adjustments: The calculator doesn’t include cost-of-living adjustments, which can increase real-world payouts over time.
- Lump Sum vs. Monthly Payments: While FERS doesn’t offer a lump sum payout by default, calculating its equivalent helps in comparing financial strategies.
