FERS MRA+10 Retirement 2026: Real Math, 3 Worked Examples, and the 5% Penalty Trap

Last Updated: April 23, 2026 Reading Time: 15 min

Most content on FERS MRA+10 retirement repeats the same surface facts and misses the math that actually matters. Reddit's r/govfire has been flagging this for months. This guide does the work: the full MRA table, three original worked examples using 2026 OPM pay data, the FEHB postponement rules most articles get wrong, the FERS Supplement exclusion that surprises retirees, the TSP Rule of 55 trap, and the permanent 5% penalty mechanics nobody explains correctly.

Key Takeaways

• MRA+10 means retiring at your Minimum Retirement Age (55-57 depending on birth year) with at least 10 years of creditable civilian service.
• The 5% per year age penalty is PERMANENT and applies to your annuity immediately. It does NOT reverse or recalculate when you turn 62.
• Postponing the annuity start age is the only way to reduce or eliminate the penalty: wait to 62 for zero penalty, or to 60 with 20+ years of service.
• MRA+10 retirees are permanently excluded from the FERS Supplement. There is no bridge income from the government to age 62.
• FEHB is suspended (not permanently lost) during a postponed retirement and can be reinstated when the annuity begins, provided the 5-year enrollment rule was met before separation.
• The no-COLA-until-62 rule compounds the penalty. At 3% inflation, 5 years of frozen annuity payments erodes about 14-16% of real purchasing power.

The MRA Table: Find Your Minimum Retirement Age

Every calculation begins here. Your MRA is fixed by your year of birth under 5 U.S.C. § 8412(h).

Year of Birth	Minimum Retirement Age
Before 1948	55 years 0 months
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 0 months
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 and after	57 years 0 months

Two transition bands add 2 months per birth year (1948-1952 and 1965-1969). The 1953-1964 cohort is fixed at 56. Anyone born in 1970 or later hits the maximum MRA of 57. The first fully-57 MRA employees reach their MRA in 2027.

Who Qualifies: The Eligibility Rules

MRA+10 eligibility comes from 5 U.S.C. § 8412(d). Three requirements:

1. You must be at or above MRA on the date of separation from federal service.
2. You must have at least 10 years of creditable FERS civilian service.
3. At least 5 of those years must be civilian (automatically satisfied if you have 10+ civilian years).

What counts as creditable service

Full credit:

• FERS-covered civilian service with retirement contributions
• CSRS service if you transferred to FERS with a CSRS component
• Military service with a fully paid buyback deposit

Partial credit:

• Part-time service counts day-for-day toward eligibility, but the annuity is prorated by tour-of-duty percentage

Counts for annuity computation only, NOT eligibility:

• Unused sick leave. A person with 9 years 11 months and 400 hours of sick leave does not qualify. Sick leave adds to the service total AFTER the 10-year eligibility threshold is met.

Does NOT count:

• Military service without a completed buyback deposit
• Most non-covered service
• LWOP beyond certain thresholds

The 5% Penalty: How It Works and Why It Never Goes Away

Under 5 U.S.C. § 8415(b), the MRA+10 age reduction is 5/12 of one percent for each full month under age 62 on the date your annuity begins. That works out to 5% per year.

The formula

1. Calculate your unreduced annuity: 1% × High-3 × Years of Service
2. Count full months between your annuity start date and your 62nd birthday
3. Multiply those months by 5/12 of 1% (0.4167% per month)
4. Subtract that percentage from your unreduced annuity

The permanence rule

This is what r/govfire keeps flagging as missing from other content: the reduction is applied once, at annuity commencement, and stays in effect every month for the rest of your life.

If your annuity starts at 57 with a 25% reduction, you receive that 25% reduction at age 62, at 72, at 82. It does not recalculate. It does not phase out. It does not reverse.

People confuse this with the COLA rule, which says cost-of-living adjustments begin at 62. COLAs do start at 62 for MRA+10 retirees. The penalty never stops.

When the penalty does not apply

Per OPM's eligibility guidance, the penalty is completely eliminated in three situations:

• 30+ years of service at MRA (standard MRA+30, no reduction applies at all)
• 20+ years of service with annuity starting at age 60 (MRA+20 provision)
• Annuity starting at age 62 with any service length ≥ 10 years

Postponed Retirement: The Full Mechanics

Postponed retirement lets you separate at MRA with 10+ years but delay applying for your annuity. Done correctly, it reduces or eliminates the penalty.

How to implement it

1. Separate from federal service normally
2. Do NOT file Form SF-3107 at separation (or file Form RI 92-19 specifying a future commencement date)
3. Wait until the target start date
4. Submit your retirement application about 2 months before you want the annuity to begin

Penalty elimination thresholds

Situation	Minimum start age	Service required	Penalty
Immediate MRA+10	MRA (55-57)	10+ years	5% × years under 62
Postponed (partial)	Between MRA and 62	10+ years	5% × years still under 62
Postponed, no penalty (20 yrs)	60	20+ years	None
Postponed, no penalty (any yrs)	62	10+ years	None

Every year of postponement beyond MRA is worth 5% of your unreduced annuity. You do not have to postpone all the way to 62 to get benefit.

What you give up during postponement

Benefit	During postponement period
FERS annuity payments	None
FEHB as retiree	Suspended
FEGLI	Suspended
FEDVIP dental/vision	Suspended
FERS Supplement	N/A (MRA+10 never qualifies)
COLAs	Begin at 62 when annuity starts

The FEHB suspension is NOT permanent loss. That's the critical distinction from deferred retirement covered below.

FEHB During Postponement: The Detail That Matters

Most content gets this wrong. Here is what actually happens.

Your options during the gap

Option 1: Temporary Continuation of Coverage (TCC)

• Up to 18 months from separation
• Full premium (employee + government shares) plus 2% administrative fee
• 2026 estimate: a mid-tier family plan that cost you ~$600/month as an employee runs roughly $1,700-$2,200/month under TCC
• 60-day election window
• Keeps your exact current plan with no underwriting

Option 2: ACA marketplace

• Federal separation is a qualifying life event
• Subsidy eligibility depends on gap-year income (TSP withdrawals count)
• Does NOT count toward the 5-year FEHB rule

Option 3: Spouse's employer plan

• Often the cheapest bridge if available

Re-enrolling when the annuity starts

When you submit the annuity commencement application, you can elect to re-enroll in FEHB. The government resumes paying its ~72% share. The catch: you must have been continuously enrolled in FEHB for the 5 years immediately BEFORE separation. The postponement gap doesn't break the clock because OPM evaluates the 5-year period as of your separation date, not the annuity start date.

If you weren't enrolled for 5 years before separation, you cannot re-enroll as a retiree. Period. That's a different issue from the postponement gap.

Postponed vs deferred: the expensive difference

Feature	Postponed retirement	Deferred retirement
Eligibility	Left at or after MRA with 10+ years	Left before MRA with 5+ years
FEHB after annuity starts	Can re-enroll (5-year rule applies)	Permanently lost
FEGLI after annuity starts	Can re-enroll	Permanently lost
Penalty math	Same 5%/year	Same 5%/year

The FEHB difference alone can be worth $150,000-$300,000 over a 20-year retirement. We have a full post on deferred vs postponed retirement if you want to go deeper.

FERS Supplement: MRA+10 Retirees Never Qualify

The FERS Special Retirement Supplement pays roughly 40-60% of what your Social Security benefit will be, bridging the gap from retirement to age 62.

Per Chapter 51 of the CSRS/FERS Handbook, the Supplement is available ONLY to:

• MRA+30 retirees (full retirement)
• Age-60-with-20-years retirees
• Certain VERA and discontinued service retirees

MRA+10 retirees are explicitly excluded. OPM's Handbook is direct: "If you receive a deferred benefit, a disability benefit, or an immediate MRA+10 benefit, you will not be eligible for the annuity supplement."

The edge case

Q: If I postpone MRA+10 to 60 with 20 years, do I qualify for the Supplement? A: No. The retirement type is set at separation. MRA+10 postponed to 60 is still MRA+10, not "age 60 with 20 years" immediate retirement. Only the latter qualifies for the Supplement.

This is the most expensive misconception in the MRA+10 conversation. A 57-year-old retiree without the Supplement faces 5 years of no government bridge income. Your TSP has to do all the work.

TSP Access at MRA+10: The Rule of 55 and the Rollover Trap

Under IRS 26 U.S.C. § 72(t)(2)(A)(v), the 10% early withdrawal penalty does not apply to distributions from a qualified plan (which the TSP is) when the employee separates from service in or after the calendar year they turn 55.

How it applies to MRA+10

• If you separate at MRA 55 or 56, verify you are in or past the calendar year you turn 55
• If you separate at MRA 57 (born 1970+), you're comfortably past 55 at separation
• Regular income tax still applies to traditional TSP distributions
• TSP withholds 20% federal tax at withdrawal by default

The rollover trap

Rolling your TSP balance into a traditional IRA LOSES the Rule of 55 protection on those funds. IRA distributions before 59½ face the 10% penalty regardless of your separation age.

Recommendation: If you separated between 55 and 59½ and might need early access, keep your money in the TSP. You can always roll to an IRA at 59½ when the IRA penalty no longer applies.

Roth TSP considerations

Roth TSP contributions (not earnings) can be withdrawn anytime, tax-free and penalty-free, because they're after-tax money. Roth earnings need both a 5-year hold and age 59½ to be qualified. For MRA+10 retirees under 59½, Roth contributions are additional penalty-free liquidity.

The No-COLA-Until-62 Rule: The Underreported Cost

FERS annuitants under age 62 do not receive cost-of-living adjustments. Per OPM's COLA guidance, the first COLA for an MRA+10 retiree who starts their annuity before 62 arrives on January 1 of the year after they turn 62.

What that means in real dollars:

• Retire at 57 with a $12,000/year annuity (after the 5% penalty)
• For 5 years (until 62), the $12,000 does not increase for inflation
• At 3% annual inflation, the $12,000 in year 1 has the purchasing power of about $10,363 in year 5
• The first COLA at 62 is calculated on the $12,000 base, not the inflation-adjusted value
• Those 5 years of foregone COLAs are permanent

The 5% penalty cuts the annuity amount. The COLA delay erodes the purchasing power of what's left. Stack them.

Three Worked Examples Using 2026 OPM Pay Data

Every example below uses OPM's 2026 salary tables (effective January 11, 2026). High-3 is the straight average of the three highest consecutive years. These are FedTools 2026 original analyses.

Example A: GS-9 Step 7, RUS locality, MRA 57, 12 years , immediate MRA+10

Profile: Born 1970 (MRA 57). GS-9 Step 7 in a Rest-of-U.S. location. 12 years of federal service. Plans to leave at 57 and start the annuity immediately.

Step 1: With-locality salary

• 2026 GS-9 Step 7 base: $63,275
• RUS locality 2026: 17.06%
• With-locality: $63,275 × 1.1706 = $74,069

Step 2: Estimate High-3

• 2024: ~$72,638
• 2025: ~$73,364
• 2026: $74,069
• High-3: $73,357

Step 3: Unreduced annuity

• 1% × $73,357 × 12 = $8,803/year, $734/month

Step 4: Age reduction

• Years under 62: 5 (60 months)
• Reduction: 60 × 0.4167% = 25%
• Dollar reduction: $8,803 × 0.25 = $2,201/year
• Reduced annuity: $6,602/year, $550/month

Step 5: Lifetime penalty cost (retiring to age 82)

• Penalty: $6,602 × 25 = $165,050
• Full (no penalty): $8,803 × 25 = $220,075
• Lifetime cost of the penalty: ~$55,025

Additional invisible costs: No FERS Supplement, so the SS bridge comes entirely from TSP. No COLA until 62 erodes another ~14% of purchasing power over 5 years. At $550/month, the pension is a supplement, not a primary income source.

Example B: GS-13 Step 5, DC locality, MRA 56, 15 years , immediate vs postpone to 60

Profile: Born 1960 (MRA 56). GS-13 Step 5 in Washington-Baltimore-Arlington locality. 15 years of FERS service. Separating at 56. Considers immediate vs postponement to age 60.

With-locality salary

• 2026 GS-13 Step 5 base: $103,049
• DC locality 2026: 33.94%
• With-locality: $103,049 × 1.3394 = $138,022

High-3: $136,898

Unreduced annuity

• 1% × $136,898 × 15 = $20,535/year, $1,711/month

Option 1: Immediate MRA+10 at 56

• Years under 62: 6 (72 months)
• Reduction: 30%
• Annuity: $20,535 × 0.70 = $14,374/year, $1,198/month

Option 2: Postpone to age 60

• Only 15 years of service, so no 20-year penalty elimination
• Still 2 years under 62
• Reduction: 24 × 0.4167% = 10%
• Annuity: $20,535 × 0.90 = $18,481/year, $1,540/month

Break-even analysis

• Monthly gain from postponement: $1,540 − $1,198 = $342
• Foregone income during 4-year wait: $1,198 × 48 = $57,504
• Break-even: $57,504 / $342 = 168 months
• Break-even age: 60 + 14 = 74

Postponement pays off in total pension if the retiree lives past 74. Federal employees who make it to retirement typically live into their mid-80s, so postponement is favorable for most.

FEHB gap cost (age 56-60)

• TCC for first 18 months: ~$1,800-$2,200/month for a family BCBS plan
• After TCC: ACA or spouse's plan
• 4-year total: $60,000-$90,000

Add the FEHB gap to the analysis and the real break-even shifts to age 78-80. Still within normal life expectancy for a healthy 56-year-old. The decision hinges on bridge income availability and health status.

Example C: GS-12 Step 10, Atlanta, MRA 57, 25 years , is MRA+10 even the right vehicle?

Profile: Born 1970 (MRA 57). GS-12 Step 10, Atlanta locality. 25 years of FERS service. Not short on service; the question is whether MRA+10 is the best choice at all.

With-locality salary

• 2026 GS-12 Step 10 base: $99,404
• Atlanta locality 2026: 23.79%
• With-locality: $99,404 × 1.2379 = $123,044

High-3: $121,704

Unreduced annuity

• 1% × $121,704 × 25 = $30,426/year

Path A: Immediate MRA+10 at 57, 25 years

• Penalty: 25%
• Annuity: $30,426 × 0.75 = $22,820/year, $1,902/month

Path B: Postpone to 60, 25 years (not 20, so partial penalty remains)

• Penalty: 10%
• Annuity: $30,426 × 0.90 = $27,383/year, $2,282/month
• Break-even vs Path A: age 75

Path C: Stay until 60 with 28 years, then postpone (not immediate) , same 10% penalty logic

• 1% × $124,000 × 28 = $34,720/year
• After 10% penalty: $31,248/year, $2,604/month

Path D: Stay until 62 with 30 years (1.1% multiplier applies at 62 with 20+ years)

• 1.1% × $126,000 × 30 = $41,580/year, $3,465/month
• No penalty, immediate COLA eligibility, FERS Supplement not needed (already at SS age)

The takeaway for this profile: Path D pays more than 82% more than Path A. For employees with 25+ years at MRA, MRA+10 is almost never optimal unless there's a compelling external reason (health, job loss, caregiving). Every year of continued work at this grade adds roughly $1,200/year to the base annuity AND avoids 5 percentage points of penalty.

Three Misconceptions Your Retirement Planner Probably Has

Misconception 1: "The penalty goes away at 62"

Wrong. The 5% per year penalty is applied once, permanently, when your annuity begins. If your pension starts at 57 with a 25% reduction, you receive that reduction every month for the rest of your life , including after 62.

People confuse this with the COLA rule (COLAs start at 62) and assume the pension itself resets. It doesn't.

Misconception 2: "Postponing means deferring, so I lose FEHB either way"

Wrong. These are legally distinct retirement types.

• Deferred retirement (left before MRA) = FEHB permanently lost, forever
• Postponed retirement (left at or after MRA with 10+ years under MRA+10) = FEHB suspended during gap, can be reinstated when annuity starts

The difference can be worth hundreds of thousands of dollars. We have a full explainer on deferred vs postponed.

Misconception 3: "I have to postpone to 62 to get any benefit"

Wrong. Every year of postponement beyond MRA is worth 5 percentage points. You do not need to reach 62 to benefit.

Retire at	Immediate penalty	Postpone to 60 (with 20+ yrs)	Postpone to 62
MRA 57 (5 yrs under)	25%	10% (2 yrs under; 0% if 20+ yrs)	0%
MRA 56 (6 yrs under)	30%	10% (or 0% if 20+ yrs)	0%
MRA 55 (7 yrs under)	35%	10% (or 0% if 20+ yrs)	0%

Note: the "postpone to 60 with 0% penalty" only applies to employees with 20+ years. Those with 10-19 years still face the 10% penalty at age 60.

Frequently Asked Questions

What does MRA+10 mean for FERS retirement?

MRA+10 means retiring with a reduced pension at your Minimum Retirement Age (55-57 depending on birth year) with at least 10 years of creditable FERS civilian service. Your annuity is permanently reduced 5% per year under 62.

Is the 5% MRA+10 penalty permanent?

Yes. The reduction is calculated once at annuity commencement and applied every month for the rest of your life. It does not recalculate at 62.

Can I avoid the MRA+10 penalty by postponing?

Yes, partially or fully. Waiting to 62 eliminates it. If you have 20+ years, waiting to 60 also eliminates it. Any other postponement age reduces but doesn't eliminate the penalty.

What happens to my FEHB during a postponed MRA+10 retirement?

FEHB is suspended at separation. Use TCC (18 months at full premium + 2% fee), a spouse's plan, or ACA during the gap. When your annuity begins, you can re-enroll with government cost-sharing, provided you met the 5-year FEHB rule before separation.

Do I qualify for the FERS Supplement with MRA+10?

No. MRA+10 retirees are explicitly excluded. Bridge income to 62 must come from TSP, savings, or other sources.

Can I access my TSP at MRA+10 without the 10% early withdrawal penalty?

Yes, if you separate in or after the calendar year you turn 55 (IRS Rule of 55). The exception only works if money stays in the TSP. Rolling to an IRA loses the protection.

When do COLAs start on my MRA+10 pension?

Not until the year after you turn 62. FERS annuitants under 62 do not receive COLAs.

What's the difference between postponed and deferred retirement?

Postponed = left at or after MRA with 10+ years; can re-enroll in FEHB when annuity starts. Deferred = left before MRA with 5+ years; FEHB permanently lost.

Does sick leave count toward the 10 years required for MRA+10?

No. Sick leave adds to annuity computation AFTER eligibility, but doesn't count toward the 10-year threshold.

Does military buyback count toward MRA+10?

Yes, if the deposit is fully paid before retirement.
