Federal Annuity Calculator
Planning your federal retirement? Understanding how much you can expect in annual income is one of the most critical steps. That’s where our Federal Annuity Calculator comes in. Whether you’re covered under FERS (Federal Employees Retirement System) or CSRS (Civil Service Retirement System), this tool gives you a reliable estimate of your yearly annuity — in seconds.
What Is the Federal Annuity Calculator?
The Federal Annuity Calculator is a web-based tool that helps federal employees estimate their annual retirement income based on the high-3 average salary, years of service, and their retirement system (FERS or CSRS). This tool simplifies complex retirement formulas, ensuring you can plan with clarity and confidence.
Why it matters:
Your federal annuity is the cornerstone of your retirement income, and understanding its potential value allows you to plan when to retire, how much to save, and what kind of lifestyle you can maintain post-retirement.
How to Use the Calculator – Step-by-Step
- Enter Your High-3 Salary
This is the average of your highest-paid consecutive 3 years of federal service. Input it in dollars (e.g., 78000.00). - Enter Your Years of Service
Provide the total number of credible service years, including any eligible military or unused sick leave that counts toward your annuity. - Select Your Retirement System
Choose either:- FERS – for most federal employees hired after 1984.
- CSRS – for employees hired before 1984 (and who didn’t opt into FERS).
- Click “Calculate”
The calculator instantly processes your data and displays your estimated annual annuity. - Click “Reset”

Example: Estimating a FERS Annuity
Let’s walk through a practical example.
- High-3 Average Salary: $85,000
- Years of Service: 22
- Retirement System: FERS
Calculation logic:
For FERS employees with 20+ years of service, the multiplier increases from 1% to 1.1%.
So, the annuity = 85,000 x 22 x 0.011 = $20,570
Your estimated annual annuity would be $20,570.00.
FERS vs. CSRS: What’s the Difference?
Understanding the difference between FERS and CSRS is key when interpreting your annuity results.
FERS (Federal Employees Retirement System)
- Applies to employees hired in 1984 or later.
- Retirement benefit is typically smaller than CSRS.
- Employees also receive Social Security and Thrift Savings Plan (TSP) benefits.
- Base multiplier is 1% of high-3 salary times years of service (1.1% if retiring at age 62+ with 20+ years).
CSRS (Civil Service Retirement System)
- Applies to employees hired before 1984.
- No Social Security benefits (for most).
- Higher annuity multiplier: 2% of high-3 salary per year of service.
- Offers a much more substantial fixed pension.

15+ Frequently Asked Questions (FAQs)
1. What is a high-3 salary?
Your high-3 salary is the average of your highest-paid consecutive 3 years of basic pay. It doesn’t include bonuses, overtime, or locality pay.
2. How is the FERS annuity calculated?
FERS annuity = High-3 salary × Years of service × 1%. If you have 20+ years and retire at age 62 or later, the multiplier increases to 1.1%.
3. How is the CSRS annuity calculated?
CSRS annuity = High-3 salary × Years of service × 2%. It’s a more generous formula than FERS but doesn’t include Social Security.
4. Does the calculator factor in early retirement penalties?
No, this calculator assumes full retirement without reductions. Early retirement may reduce benefits by up to 5% per year under certain conditions.
5. What if I have part-time service?
This calculator assumes full-time service. Part-time work may reduce your annuity and should be calculated manually or with help from OPM.
6. Does military service count toward my annuity?
Yes, if you buy back your military time, it will count toward your credible service in both FERS and CSRS.
7. Can unused sick leave increase my annuity?
Yes. Under both systems, unused sick leave can add to your service time, increasing your annuity.
8. Can I change the multiplier in the calculator?
No, it’s automatically applied based on the selected retirement system and years of service. This ensures accuracy for most users.
9. Is the output taxable income?
Yes, your federal annuity is considered taxable income at both the federal and state levels in most states.
10. What happens to my annuity if I pass away?
Survivor annuity options are available, usually reducing the retiree’s annuity slightly in exchange for continued payments to a spouse.
11. Does this calculator include COLAs (Cost of Living Adjustments)?
No, it provides a baseline annuity estimate. COLAs may be applied annually after retirement depending on the inflation rate and system rules.
12. What if I plan to retire early under FERS?
This calculator does not include penalties or MRA+10 reductions for early retirement. Consult OPM or a benefits counselor for specifics.
13. Can this tool help with TSP projections?
No. This calculator only estimates the federal pension portion (FERS or CSRS). Use a separate TSP calculator for investment growth projections.
14. Is this tool official?
No. While accurate, this calculator is a third-party tool and should be used for estimation only. Final annuity amounts are determined by OPM.
15. What if I have a break in service?
Breaks in service may affect your retirement eligibility and annuity. This calculator assumes continuous credible service.
16. Is Social Security included in the estimate?
No. FERS employees are eligible for Social Security separately, but it is not included in this annuity estimate.
17. Can I save or print the results?
Not directly from the calculator, but you can take a screenshot or copy the results manually for your records.
18. What’s the best time to retire for the highest annuity?
Generally, retiring at age 62 with 20+ years of service under FERS yields the most favorable multiplier (1.1%).
19. Can rehired annuitants use this calculator?
Only if their additional service time is eligible to increase their existing annuity. Consult HR for specifics.
20. Where can I find my official annuity statement?
Your official annuity estimate is provided by your agency’s HR department or directly from the Office of Personnel Management (OPM).
