You’re Covered — and the Claiming Age Decision Is Yours
Unlike the CSRS generation before you, every FERS postal employee pays into and collects Social Security. The question isn’t whether you get it — it’s when to take it, and the spread is enormous. Claim at 62 and you lock in a permanent 30% reduction from your full benefit. Wait until your full retirement age of 67 (for anyone born 1960 or later) and you get 100%. Hold out to 70 and delayed retirement credits push it to 124%. On a $2,000 full benefit, that’s the difference between $1,400 and $2,480 a month — for life, with COLAs compounding on whichever base you chose.
Reading the Break-Even Table
The comparison table above shows the break-even age for each claiming year — the point where waiting overtakes claiming early in cumulative dollars. Claiming at 67 instead of 62 typically breaks even in your late 70s; average life expectancy for someone who reaches 62 runs well past that, which is why waiting usually wins on paper. But “usually” isn’t “always”: health, family history, and whether you need the income to avoid draining your TSP early all belong in the decision. For the most accurate inputs, pull your real benefit estimate from your my Social Security account at ssa.gov and use the manual entry mode above — the salary-based estimate is a rough approximation.
The FERS Supplement: The Bridge Most People Can’t Price
Retire before 62 on an unreduced immediate annuity — MRA+30 or Age 60+20 — and FERS pays you a Special Retirement Supplement that approximates the Social Security you earned during federal service, bridging the gap until 62. The rough formula: your age-62 benefit × (years of FERS service ÷ 40). Thirty years of service and a $1,800 benefit means roughly $1,350 a month from your retirement date to your 62nd birthday — real money that makes MRA+30 retirement feasible for many carriers and clerks. Three hard rules: it’s not available under MRA+10 retirement, it ends at 62 whether or not you claim Social Security then, and it gets no COLAs. It’s also means-tested against wages: earn above $24,480 (2026 limit) at a post-retirement job and the supplement shrinks $1 for every $2 over — though TSP withdrawals and your annuity don’t count. Our full Social Security guide covers the supplement in depth, and it’s a factor in any early-out decision.
Putting the Three Legs Together
The income snapshot above stacks your FERS annuity, the supplement (if eligible), TSP withdrawals, and Social Security at each claiming age into one monthly total — the number that actually answers “can I afford to retire?” Estimates here are for planning; your official benefit comes from SSA and your annuity from OPM.
