How Is Your FERS Retirement Pay Calculated?

The Federal Employees Retirement System (FERS) provides a retirement plan for most civilian employees of the U.S. federal government. Established in 1987, FERS replaced the Civil Service Retirement System (CSRS) for new hires. FERS offers financial security during retirement through a combination of benefits.

Calculating the FERS Basic Annuity

The foundation of a FERS retiree’s income is the basic annuity, a defined benefit pension plan that provides a guaranteed monthly payment for life. This annuity is calculated using a specific formula that considers three primary elements: years of creditable service, the “High-3” average salary, and an annuity factor.

Creditable service refers to the total time a federal employee has worked for the government that counts toward their retirement eligibility and annuity computation. This generally includes federal civilian service where FERS retirement deductions were withheld from pay. Military service can also be included if a deposit is made to cover that period. Unused sick leave can also be added to an employee’s creditable service for annuity computation, though it does not count toward eligibility to retire. Each day of full or part-time service counts, provided the employee contributed to FERS.

The “High-3” average salary represents the highest average basic pay an employee earned during any three consecutive years of service. While this period often aligns with the final three years of employment, it can be any 36 consecutive months where the salary was highest. This average includes basic pay and locality pay but excludes other forms of compensation such as overtime, bonuses, or allowances.

The annuity factor, also known as the multiplier, is applied to the High-3 salary and years of service to determine the annual basic annuity. For most FERS retirees, this factor is 1.0%. However, for those who retire at age 62 or older with at least 20 years of creditable service, the annuity factor increases to 1.1%.

The formula for calculating the FERS basic annuity is: (High-3 Average Salary) x (Years of Creditable Service) x (Annuity Factor). For example, a retiree with a $100,000 High-3 salary, 30 years of service, and an annuity factor of 1.0% would receive an annual basic annuity of $30,000. If that same individual qualified for the 1.1% factor, their annuity would be $33,000. Minimum service requirements for immediate retirement include being age 62 with 5 years of service, age 60 with 20 years, or reaching one’s Minimum Retirement Age (MRA) with 30 years of service.

Integrating Social Security with FERS

FERS is structured as a three-tiered retirement system, with Social Security serving as a component alongside the basic annuity and the Thrift Savings Plan. Unlike the older Civil Service Retirement System (CSRS), FERS employees contribute to Social Security through payroll deductions, like most private sector workers. These contributions make FERS retirees eligible for Social Security benefits, which form part of their total retirement income.

Social Security benefits are calculated by the Social Security Administration (SSA) based on an individual’s earnings record over their career. The amount received depends on factors such as lifetime earnings and the age at which benefits are claimed. Claiming benefits at one’s Full Retirement Age (FRA) allows for 100% of the earned benefit. The FRA varies based on birth year, gradually increasing from age 66 to 67 for those born in 1960 or later.

Claiming Social Security benefits before reaching the FRA results in a permanent reduction in monthly payments. Conversely, delaying benefits past the FRA, up to age 70, can lead to increased monthly payments. These decisions impact the Social Security portion of a FERS retiree’s income.

Two provisions, the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO), can impact FERS retirees’ Social Security benefits. WEP can reduce the Social Security benefit for individuals who receive a pension from non-covered employment (where Social Security taxes were not paid) and also have Social Security-covered earnings. While FERS employees contribute to Social Security, WEP mainly affects those with other non-federal pensions.

GPO can reduce or eliminate Social Security spousal or survivor benefits for individuals who also receive a government pension based on their own non-Social Security-covered federal, state, or local government employment. GPO could affect a FERS retiree if they also receive a pension from previous employment not covered by Social Security.

Thrift Savings Plan for FERS Participants

The Thrift Savings Plan (TSP) functions as the third pillar of the FERS retirement system, operating as a defined contribution plan similar to a private sector 401(k). It allows federal employees to save for retirement on a tax-deferred basis, or tax-free with Roth contributions. The TSP is a component of the FERS retirement package, providing an avenue for wealth accumulation.

Contributions to the TSP come from several sources. Employees can make their own contributions, choosing between traditional (pre-tax) or Roth (after-tax) options. The federal agency automatically contributes an amount equal to 1% of the employee’s basic pay to their TSP account each pay period, regardless of employee contributions.

The agency also provides matching contributions on employee contributions, up to a certain percentage of basic pay. The agency matches the first 3% of an employee’s contributions dollar-for-dollar, and 50 cents on the dollar for the next 2%, totaling a potential 5% agency contribution if the employee contributes at least 5%. These agency contributions boost retirement savings.

Upon retirement, FERS participants have several options for withdrawing funds from their TSP accounts. These include lump-sum withdrawals, installment payments (fixed dollar amounts or based on life expectancy), or purchasing an annuity from a TSP vendor for guaranteed monthly payments.

It is important to consider the tax implications of withdrawals. Traditional TSP funds are fully taxable as ordinary income. Roth TSP withdrawals are tax-free in retirement if certain conditions are met, as contributions were made with after-tax dollars.

Factors Influencing Your Total FERS Retirement Income

Beyond the core components of the basic annuity, Social Security, and the Thrift Savings Plan, several additional factors can influence a FERS retiree’s total income. The age at which an employee chooses to retire impacts the amount and timing of their basic annuity. For instance, retiring at the Minimum Retirement Age (MRA) with fewer than 30 years of service can result in a permanent reduction in the annuity. Alternatively, delaying retirement can increase the annuity amount, especially for those reaching age 62 with 20 or more years of service.

Cost-of-Living Adjustments (COLAs) are applied to the FERS basic annuity to preserve purchasing power against inflation. These adjustments are effective in January each year and are based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). FERS COLAs differ from those for Social Security and CSRS, as they can be limited if inflation is above a certain threshold, and FERS retirees do not receive COLAs until age 62, with exceptions for disability or special provision retirements.

The decision to elect a survivor benefit for a spouse will reduce the retiree’s monthly annuity payment. The amount of the reduction depends on the level of survivor benefit elected.

Premiums for federal health and life insurance programs, such as the Federal Employees Health Benefits (FEHB) and Federal Employees’ Group Life Insurance (FEGLI), are deducted directly from a retiree’s annuity payments. Maintaining these benefits into retirement is an aspect of the FERS package.

FERS disability retirement has a different calculation method compared to regular optional retirement. Eligibility requires meeting specific medical and service requirements, including at least 18 months of federal civilian service. The annuity calculation for disability retirement can vary based on age and years of service.
