Planning for retirement is one of the most important financial steps you can take, especially if you’re a federal employee covered under the Federal Employees Retirement System (FERS). Knowing what your deferred retirement benefits will look like helps you make informed decisions about your career, savings, and retirement timeline.
Our FERS Deferred Retirement Calculator is a simple yet powerful tool that allows you to quickly estimate your annual and monthly pension benefits based on your high-3 average salary, years of service, and retirement age.
In this guide, we’ll explain how the calculator works, why it’s useful, and provide examples so you can better understand how your FERS retirement benefits are calculated.
FERS Deferred Retirement Calculator
hat Is the FERS Deferred Retirement Calculator?
The FERS Deferred Retirement Calculator is an online tool designed for federal employees who want to estimate their future pension benefits when they separate from federal service before reaching retirement eligibility.
Under FERS, your pension is based on three factors:
- High-3 Average Salary – The highest average basic pay you earned during any consecutive 36 months of federal service.
- Years of Creditable Service – The total years you worked in a position covered by FERS.
- Age at Retirement – Your age when you start collecting your deferred pension.
The calculator uses these inputs to apply the official FERS pension formula and provides an estimate of both annual pension and monthly pension.
How the FERS Pension Formula Works
The FERS pension formula is straightforward:
Annual Pension = High-3 Salary × Years of Service × Multiplier
- Multiplier = 1% if you retire before age 62 or with less than 20 years of service
- Multiplier = 1.1% if you retire at age 62 or older with 20 or more years of service
This small difference in the multiplier can make a noticeable impact on your retirement income. That’s why it’s important to use the calculator to see how different scenarios affect your pension.

Example Pension Calculations
To give you a better understanding, here are a few sample calculations:
Example 1: Retiring at Age 60 with 25 Years of Service
- High-3 Salary: $90,000
- Years of Service: 25
- Age at Retirement: 60
- Multiplier: 1% (since under age 62)
Annual Pension = $90,000 × 25 × 0.01 = $22,500
Monthly Pension = $1,875
Example 2: Retiring at Age 62 with 20 Years of Service
- High-3 Salary: $100,000
- Years of Service: 20
- Age at Retirement: 62
- Multiplier: 1.1% (since age 62+ with 20+ years)
Annual Pension = $100,000 × 20 × 0.011 = $22,000
Monthly Pension = $1,833
Example 3: Retiring at Age 65 with 30 Years of Service
- High-3 Salary: $120,000
- Years of Service: 30
- Age at Retirement: 65
- Multiplier: 1.1%
Annual Pension = $120,000 × 30 × 0.011 = $39,600
Monthly Pension = $3,300
Why Use a FERS Calculator?
Planning ahead ensures you don’t run into financial surprises during retirement. Here’s why this calculator is useful:
- Quick Estimates: Get instant pension calculations without complicated math.
- Scenario Planning: Test different retirement ages and service years to maximize benefits.
- Retirement Confidence: Know what to expect so you can better plan your savings.
- Decision Making: Helps you decide whether to stay longer in federal service.
Tips to Maximize Your FERS Pension
- Work at Least 20 Years – Reaching 20 years of service at age 62 boosts your multiplier to 1.1%.
- Increase Your High-3 Salary – Promotions and step increases during your final years can significantly raise your pension.
- Delay Retirement – Even waiting a couple of years can result in a higher monthly income.
- Coordinate with TSP & Social Security – Remember, your pension is only one part of FERS; your Thrift Savings Plan (TSP) and Social Security also contribute to your retirement income.
Frequently Asked Questions (FAQs)
