What are the minimum service and age requirements for House members to receive full retirement benefits?

1. Minimum service to qualify: five years is the gatekeeper

By statute and CRS reporting, the basic vesting requirement to be “entitled to a pension benefit under CSRS or FERS” is five years of federal service — that threshold applies to Members of the House, so a single two‑year term typically does not vest a pension entitlement ^{[1] [2]}. FactCheck.org’s review likewise notes that only after the required service threshold are members eligible for annuities, and that short House tenures generally do not produce significant pensions ^[4].

2. Age matters: the earliest “full” unreduced retirement often cited is 62

Under FERS — the system that covers most modern members — the commonly referenced benchmark for an unreduced annuity is age 62 with at least five years of service; members who meet the age-and-service combination can receive an unreduced benefit, while taking a pension earlier generally reduces the annual amount ^{[3] [5]}. OPM and Federal Register material note that Members first elected after certain dates have differing age/years rules, and that FERS rules have changed over time, which affects when a member can retire without actuarial reduction ^[5].

3. Reduced pensions if you retire earlier or with fewer years

If a member takes a FERS pension before the unreduced age — for example, at age 55 with 10 years of service — the annuity is reduced by a formula tied to years of service and the difference between retirement age and the unreduced age (Wikipedia’s summary, reflecting typical FERS formulas, gives an example: a 10‑year member taking FERS at 55 receiving a reduced calculation equal to roughly 11% of the high‑3 salary after the applicable reduction) ^[6]. CRS and GAO reporting emphasize that the amount depends on plan, age, and length of service ^{[2] [7]}.

4. How big can a congressional pension be? The legal cap and typical outcomes

By law, a member’s starting annuity cannot exceed 80% of final salary; calculators and analysis note the pension can theoretically reach up to 80% of the member’s final pay, but that requires long service and other conditions ^{[4] [3]}. In practice, average FERS retiree pensions have been much lower — historical CRS and watchdog reports put average FERS pensions for former members in the tens of thousands annually, not near the 80% cap ^{[4] [6]}.

5. Variations over time and special cohorts: CSRS, CSRS‑Offset, and hire‑date rules

Retirement rules for Members of Congress are not uniform across history: some members remain under older systems (CSRS or CSRS‑Offset) depending on when they began service, and benefit accrual rates and age/years thresholds changed with legislative reforms (for example, the 2012 Act and later changes altered accruals and deductions). Thus the five‑year vesting rule is a consistent threshold for entitlement, but the pension formula and earliest unreduced age depend on the plan and the member’s entry date ^{[1] [5] [8]}.

6. Disagreements, simplifications, and common public misunderstandings

Public and political narratives often simplify or overstate outcomes (e.g., “one‑term members receiving full salary for life”); FactCheck.org and CRS material explicitly rebut such claims, noting that only senators in limited circumstances or very long‑serving members approach high replacement rates and that one House term generally does not vest a pension ^{[4] [2]}. Advocacy groups and watchdogs sometimes present pension generosity comparisons to private sector norms, focusing attention on benefit levels for those with five or more years of service ^{[9] [3]}.

7. What the available sources do not say (limitations)

Available sources do not provide a single line “one‑size‑fits‑all” age/service table for House members in this dataset; instead, they present the key legal points (five‑year vesting), common FERS benchmarks (age 62 with five years for unreduced), and examples of reduced calculations ^{[1] [3] [6]}. For precise, individualized calculations (e.g., how a specific member’s high‑3 salary, exact hire/election date, or prior federal service affects an annuity), consult OPM or the detailed statutory tables — those granular numbers are not included in the current search excerpts ^[5].

If you want, I can pull together a concise chart of typical age-and-service combinations cited in these rules (e.g., age 62/5 years unreduced under FERS; age 55 with 10 years reduced examples) using the cited sources, or fetch OPM/CRS tables to show exact formulas and reductions.
