Your Estimated FERS Pension
Based on the information you entered.
This is an educational estimate of the basic FERS annuity, not an official retirement determination. It does not automatically apply MRA+10 or other early-retirement reductions, survivor-benefit elections, taxes, insurance premiums, or special-category retirement rules. Unused sick leave is not included in this initial version. Your actual benefit may differ. Confirm your service record, eligibility, and estimate with your agency’s retirement office or the U.S. Office of Personnel Management (OPM).
FERS Pension Guide
How Is Your FERS Retirement Pension Calculated?
A Federal Employees Retirement System (FERS) pension calculator estimates the basic retirement annuity you may receive after leaving federal service. For most regular FERS retirements, the calculation uses your high-3 average basic pay and your creditable years of service. Your age and retirement category also matter because they can affect the formula, eligibility, and whether your benefit is reduced.
Use the calculator above to estimate your annual and monthly basic pension. The estimate is a starting point for retirement planning, not an official decision about when you can retire or how much OPM will pay.
The general multiplier is 1.0%. It is generally 1.1% for employees who separate for retirement at age 62 or older with at least 20 years of creditable service. Special retirement categories can follow different rules.
1. What Is Your High-3 Average Salary?
Your FERS high-3 is generally the highest average basic pay you earned during any three consecutive years of creditable service. These are often your final three years of employment, but an earlier period may produce a higher average. The figure is based on qualifying basic pay, not simply your take-home pay or total compensation.
Overtime, bonuses, and other payments that are not considered basic pay for retirement purposes generally do not count toward the high-3 calculation. If you are unsure which salary figure applies, ask your agency’s human resources or retirement office.
2. How Creditable Service Affects Your FERS Pension
Creditable service is the service recognized under federal retirement rules for calculating your annuity. More creditable service generally increases the basic pension when the other calculation factors remain the same. However, your official service record determines the amount that can be counted.
Breaks in employment, part-time work, certain military service, and periods requiring a deposit or redeposit may need individual review. For the official calculation, OPM also excludes any fractional part of a month when determining the service period used in the annuity formula.
The 1% FERS Formula
The standard formula is 1% of your high-3 average basic pay multiplied by your creditable years of service. It applies to many regular FERS annuity calculations, subject to the applicable retirement rules.
The 1.1% FERS Formula
The higher 1.1% multiplier generally applies when you separate for retirement at age 62 or older with at least 20 years of creditable service. It should not be applied automatically to every employee aged 62 or older.
FERS Pension Calculation Example
Consider a federal employee with a high-3 average basic salary of $100,000 and 20 years of creditable service. The following example illustrates the general 1% formula, assuming it applies to the employee’s circumstances.
Hypothetical calculation using the 1.0% multiplier
This example illustrates the formula, not retirement eligibility. An employee who qualifies for the 1.1% formula would have a different estimate. Applicable age reductions, survivor benefits, unpaid deposits, and other adjustments may also change the amount payable.
What Does a FERS Pension Estimate Include?
The basic FERS annuity is one part of the federal retirement system. FERS retirement income can also involve Social Security and the Thrift Savings Plan (TSP). Those benefits are calculated separately and are not included in the basic pension estimate shown by this calculator.
The FERS Special Retirement Supplement may also be available to eligible retirees under specific conditions. It is a separate benefit with its own eligibility rules and calculation. This calculator does not estimate the supplement.
Does This FERS Calculator Determine When You Can Retire?
No. A pension formula and retirement eligibility are two different questions. Immediate retirement eligibility generally depends on a combination of your minimum retirement age (MRA), age, and creditable service. For example, standard eligibility pathways include MRA with 30 years of service, age 60 with 20 years, or age 62 with 5 years, subject to the applicable rules and exceptions.
MRA+10 retirement has separate conditions and can involve a permanent age-related annuity reduction if payments begin early. Check your birth year, service history, and intended retirement date against official OPM guidance before making a decision.

Planning Your Retirement Date
When Can You Retire Under FERS?
Your Federal Employees Retirement System (FERS) retirement eligibility depends mainly on your age and creditable service. The earliest date you can leave federal service and receive an immediate pension may differ from the date you qualify for an unreduced annuity. Understanding these rules can help you interpret your FERS pension estimate and plan your next steps before leaving government employment.
The three common voluntary immediate retirement pathways for regular FERS employees are reaching age 62 with at least five years of creditable civilian service, age 60 with at least 20 years, or your Minimum Retirement Age (MRA) with at least 30 years. A separate MRA+10 provision may allow retirement with a reduced annuity.
FERS retirement eligibility at a glance
Age and service work together. Having enough years of service does not automatically mean you can begin collecting an immediate annuity. Your birth year, service history, retirement category, and benefit start date can all affect eligibility.
Standard FERS immediate retirement requirements
The following table summarizes common voluntary retirement pathways for regular FERS employees. Special-category employees and early retirement approved under specific circumstances may follow different requirements.
| Minimum age | Creditable service | General rule |
|---|---|---|
| Age 62 | At least 5 years | Standard immediate retirement pathway. |
| Age 60 | At least 20 years | Standard immediate retirement pathway. |
| Your MRA | At least 30 years | Standard immediate retirement pathway. |
| Your MRA | At least 10 years, but less than 30 | MRA+10 rules apply; an age reduction may apply. |
These are general rules, not a determination of individual eligibility. Special provisions, qualifying early retirement, and other circumstances can change the applicable requirements.
What Is the FERS Minimum Retirement Age (MRA)?
The Minimum Retirement Age is the earliest age at which a regular FERS employee can qualify for certain retirement benefits, provided the service requirements are also met. Your MRA depends on your year of birth.
| Year of birth | Minimum retirement age |
|---|---|
| Before 1948 | 55 years |
| 1948 | 55 years, 2 months |
| 1949 | 55 years, 4 months |
| 1950 | 55 years, 6 months |
| 1951 | 55 years, 8 months |
| 1952 | 55 years, 10 months |
| 1953–1964 | 56 years |
| 1965 | 56 years, 2 months |
| 1966 | 56 years, 4 months |
| 1967 | 56 years, 6 months |
| 1968 | 56 years, 8 months |
| 1969 | 56 years, 10 months |
| 1970 or later | 57 years |

What Is MRA+10 Retirement?
MRA+10 generally applies when you have reached your Minimum Retirement Age and have at least 10 years of creditable service, but do not qualify under a more favorable immediate retirement pathway. Starting the annuity before age 62 can cause a permanent reduction. In qualifying cases, postponing the start date can reduce or avoid that age-related reduction.
What Is Deferred FERS Retirement?
A former federal employee may qualify for a deferred annuity after leaving service before meeting the requirements for immediate retirement. Generally, at least five years of creditable civilian service are required. The benefit can begin when the applicable age and service conditions are met, provided the employee has not taken a refund of retirement contributions that would affect eligibility.
How Does the MRA+10 Pension Reduction Work?
Under the general MRA+10 rules, the annuity is reduced by 5% for each year the benefit begins before age 62, calculated at 5/12 of 1% for each full month. For example, beginning an annuity several years before age 62 can substantially lower the monthly amount. This reduction is different from the basic FERS pension formula described in the previous section.
If you qualify for MRA+10, postponing the annuity start date may reduce or eliminate the age reduction, depending on your age and service. However, postponing payments can affect the timing of health and life insurance coverage. Review the full consequences with your agency retirement office before making a decision.
How TSP Fits Into Your Federal Retirement Plan
Your FERS basic pension is only one part of retirement income. Your Thrift Savings Plan (TSP) account is separate and depends on contributions, investment performance, fees, and withdrawal choices. If you are still working toward your annual TSP contribution target, use Ghaline’s TSP Catch-Up Contribution Calculator to estimate the contribution needed from your remaining paychecks. The TSP estimate and your FERS pension estimate should be considered separately.

Frequently Asked Questions About FERS Retirement
Get answers to common questions about FERS pension calculations, high-3 salary, retirement eligibility, annuity reductions, and the benefits that may affect your federal retirement income.
How is a FERS retirement pension calculated?
A standard FERS basic annuity is generally calculated by multiplying your high-3 average basic pay by your creditable years of service and an applicable benefit factor.
For most regular FERS employees, the formula is 1% of high-3 pay multiplied by years of service. If you retire at age 62 or older with at least 20 years of creditable service, the formula is generally 1.1% instead.
Use the FERS retirement calculator above to estimate your annual and monthly basic annuity. Your actual benefit may differ because of eligibility rules, service records, and applicable reductions.
What is the FERS high-3 average salary?
Your high-3 is generally the average of your highest-paid consecutive 36 months of basic pay covered by the applicable retirement rules. It is not necessarily your current salary or your highest single year’s earnings.
Certain bonuses, overtime, allowances, and other payments may not count as basic pay for retirement purposes. Check your official employment and retirement records to determine the correct amount for your situation.
Learn more from the official OPM FERS computation guidance.
When does the FERS pension formula use 1.1% instead of 1%?
Under the general FERS formula, the 1.1% factor usually applies when you are at least 62 years old at retirement and have at least 20 years of creditable service. Otherwise, the standard factor is generally 1%.
For example, with a $100,000 high-3 and 20 years of service, the basic formula produces an estimated $20,000 per year using 1%, compared with $22,000 per year using 1.1%. These figures are before applicable reductions and other adjustments.
How much is a FERS pension after 20 years of service?
The amount depends on your high-3 average basic pay and the applicable formula. With a $100,000 high-3, 20 years of service, and the standard 1% factor, the estimated basic annuity is $20,000 per year, or about $1,666.67 per month before reductions.
If you qualify for the 1.1% factor, the same example would be $22,000 per year, or about $1,833.33 per month. Having 20 years of service alone does not automatically qualify you for the 1.1% factor or establish retirement eligibility.
Can I retire under FERS at age 57?
Age 57 is the Minimum Retirement Age (MRA) for employees born in 1970 or later. Reaching your MRA does not automatically mean you qualify for an unreduced immediate pension.
Common voluntary retirement combinations include age 57 with at least 30 years of service, age 60 with at least 20 years, or age 62 with at least 5 years. MRA plus 10 years of service may also allow retirement, but an age reduction can apply. Special retirement categories can have different rules.
Review the OPM FERS eligibility requirements before making a retirement decision.
What is the FERS MRA+10 retirement rule?
MRA+10 generally applies when you have reached your Minimum Retirement Age and have at least 10 years of creditable service, but do not qualify for another immediate retirement category.
If your annuity begins before age 62, it is generally reduced by 5% for each year you are under 62, calculated at 5/12 of 1% for each full month. Exceptions and postponement options may affect the reduction.
Review the OPM explanation of FERS retirement types for details about your circumstances.
Does the FERS calculator include Social Security and TSP?
No. This calculator estimates the basic FERS pension using your high-3 average pay, age, and service entered above. It does not combine your pension with Social Security benefits or your Thrift Savings Plan (TSP) balance.
Your total retirement income may include a FERS annuity, Social Security, TSP withdrawals, and potentially a FERS annuity supplement if you meet the applicable requirements. Each benefit has its own eligibility and calculation rules.
You can also use our TSP Catch-Up Contribution Calculator to estimate contributions toward your TSP savings goal.
Does this FERS pension estimate include survivor benefits, taxes, or insurance?
No. The estimate is a basic calculation, not a final net-retirement income figure. It does not calculate survivor annuity elections, federal or state income taxes, health insurance premiums, life insurance costs, or every possible adjustment to your benefit.
These factors can change the amount you receive. For a personalized estimate, review your official retirement records and consult your agency’s benefits office or a qualified retirement professional.
What happens to my FERS pension if I leave federal service before retirement?
You may qualify for a deferred FERS annuity if you leave federal service before meeting the requirements for an immediate retirement benefit. Eligibility depends on your creditable civilian service, age, and other rules.
A refund of your retirement contributions can affect your future annuity rights. Before requesting a refund or leaving federal service, review your options with your agency’s benefits office and consult OPM’s retirement guidance.
Is the FERS retirement calculator estimate guaranteed?
No. This tool provides an educational estimate based on the information you enter and the simplified formula described on this page. It does not verify your official service history, determine your eligibility, or account for every special rule and deduction.
For an official retirement estimate, contact your agency’s human resources or benefits office and consult the Office of Personnel Management’s FERS resources.
