Federal employees approaching retirement often face a choice between two valuable but mutually exclusive benefits: the FERS Retiree Annuity Supplement and the 10% pension bonus available at age 62. Understanding exactly how each works, and what you give up by choosing one over the other, is one of the most important calculations in federal retirement planning.
What Is the FERS Retiree Annuity Supplement?
The FERS Retiree Annuity Supplement (RAS) is a monthly payment added automatically to the annuity of eligible federal employees who retire before age 62. It is designed to approximate the Social Security benefit you earned through your federal service, bridging the income gap until you can file for Social Security at 62.
To qualify, you must retire under a pathway that produces an immediate unreduced annuity. That means one of the following:
- Minimum Retirement Age (MRA) with at least 30 years of service
- Age 60 with at least 20 years of service
- VERA or DSR eligibility (supplement begins at MRA)
The supplement is calculated by dividing your years of FERS service by 40 and multiplying by your estimated Social Security benefit at age 62. An employee with 30 years of service and an estimated Social Security benefit of $1,500 per month would receive a supplement of $1,125 per month, that’s $13,500 per year in additional guaranteed income.
The supplement ends at 62 regardless of whether you file for Social Security, receives no COLAs, and is subject to an earnings test. In 2026, that threshold is $24,480. For every $2 earned above that limit, the supplement is reduced by $1.
What is the 10% Pension Bonus?
Federal employees who retire at age 62 or older with at least 20 years of creditable service receive an enhanced annuity multiplier of 1.1% per year of service instead of the standard 1%. That 10% increase is permanent; it applies to every monthly payment for the rest of your life, including future COLAs.
The difference compounds meaningfully over a long retirement. An employee with a $95,000 high-3 salary and 22 years of service illustrates the gap clearly:
- Standard formula: 1.0% x 22 x $95,000 = $20,900 per year
- Bonus formula: 1.1% x 22 x $95,000 = $22,990 per year
- Annual difference: $2,090, every year, for life
Over a 20-year retirement, that difference totals more than $41,800 before accounting for COLAs. Because the bonus applies to the base annuity, every future COLA is calculated on a slightly higher starting amount, widening the gap further over time.
The 10% bonus also increases the survivor annuity, since survivor benefits are calculated as a percentage of the unreduced annuity.
Why You Can’t Have Both
The supplement requires retiring before 62 under an immediate unreduced annuity. The 10% bonus requires retiring at 62 or later with at least 20 years of service. The eligibility windows do not overlap.
More importantly, this is not a decision you can revisit. Your retirement pathway is elected when you submit your application and cannot be changed after the fact. An employee who retires at 57, collects the supplement for five years, and then turns 62 does not become eligible for the bonus at that point. The bonus applies only to employees who are still working and retire at 62 or older. Once you retire, the formula used to calculate your annuity is locked in permanently.
Which Is Worth More?
The answer depends on three variables: how many years before 62 you plan to retire, your supplement amount, and your projected pension under both formulas.
An employee retiring at 57 with 30 years of service receives five years of supplement income. If that supplement is $1,125 per month, the total supplement received before 62 is $67,500. But waiting until 62 with two additional years of service (32 years total) and the 1.1% multiplier on the same high-3 would produce a permanently higher annuity. The math on which option delivers more lifetime income depends on how long you live and what you plan to do between your MRA and 62.
For employees who are genuinely ready to retire at their MRA and do not plan to return to full-time work, the supplement provides meaningful income during the early retirement years. For employees who can continue working until 62, the bonus typically wins on a lifetime income basis, especially for those who live into their 80s or beyond.
The Bottom Line
Neither option is universally better. The FERS supplement rewards employees who retire early and need income before Social Security. The 10% bonus rewards employees who can wait and compounds its value across a longer retirement. The right answer depends on your specific age, service history, high-3 salary, supplement estimate, and retirement timeline.
