How is the 6(c) special-provision annuity calculated?

The special-provision (6(c)) formula pays 1.7% of your high-3 salary for each of your first 20 years of covered service, then 1.0% for every year beyond 20. So 25 years of covered service equals (20 × 1.7%) + (5 × 1.0%) = 39% of your high-3. Non-covered (regular FERS) service and unused sick leave are credited at the standard 1.0% rate.

When can a federal law enforcement officer retire under 6(c)?

You can retire on an immediate, unreduced special-provision annuity at age 50 with 20 years of covered service, or at any age with 25 years of covered service. Only 6(c)-covered service counts toward these 20- and 25-year thresholds — regular FERS time and sick leave do not.

What is the mandatory retirement age for LEOs, firefighters, and air traffic controllers?

Mandatory separation is age 57 for law enforcement officers and firefighters, and age 56 for air traffic controllers, once you have the required covered service. Agencies can grant limited extensions in some cases, but separation is otherwise required by law (5 U.S.C. 8425).

Do special-provision employees get the FERS supplement, and is it reduced if I work?

Yes. Special-provision retirees receive the FERS Special Retirement Supplement immediately at retirement — they do not wait until their Minimum Retirement Age (MRA) like regular FERS retirees. Importantly, the supplement is exempt from the Social Security earnings test until you reach your MRA. After MRA it is reduced $1 for every $2 you earn over the annual limit ($24,480 in 2026), and it ends at age 62.

Does unused sick leave count toward my special retirement?

Unused sick leave is credited 100% to your annuity computation (2,087 hours equals one year of service), but it is added at the 1.0% rate and does not count toward the enhanced first-20-year tier. Sick leave also does not count toward the 20- or 25-year eligibility requirements — only actual covered service does.

Why does the enhanced 1.7% multiplier only apply to my first 20 years?

By law the enhanced 1.7% rate is capped at the first 20 years of covered service. Every year past 20 — whether covered or not — earns the standard 1.0%. This is why working well past 20 years often adds less than you would expect: your marginal year only buys 1.0% of high-3 while you forgo a pension you could already collect.

Do special-provision employees pay a higher retirement contribution?

Yes. 6(c)-covered employees contribute a higher percentage of pay toward FERS than regular employees (an extra 0.5% of basic pay) in exchange for the enhanced 1.7% multiplier and earlier eligibility. This calculator estimates your pension and supplement; it does not model your TSP or the exact contribution deduction from your paycheck.

I am a correctional officer affected by the 2026 BOP facility closures. How does this help me?

BOP correctional officers are 6(c)-covered, so this calculator shows exactly where you stand relative to the 20-year and 25-year retirement gates — the numbers that drive a relocate-versus-retire decision during a RIF. See our BOP prison closures 2026 employee guide for the closure timeline and options, and the federal law enforcement 6(c) retirement guide for the full rules.

Is this calculator official? Should I rely on it for my retirement decision?

This is a free estimate built on published OPM formulas, not an official OPM annuity computation. It holds your high-3 constant across future milestones (a conservative floor) and estimates the FERS supplement if you do not supply your SSA.gov figure. Use it to understand the trade-offs, then confirm exact numbers with your agency HR or an OPM retirement counselor before separating.

How the 6(c) special annuity works

Federal law enforcement officers, firefighters, and air traffic controllers retire under the “special provisions” of 5 U.S.C. 8412(d) — commonly called 6(c) coverage. In exchange for a higher payroll contribution, they get an enhanced 1.7% multiplier on their first 20 years and the ability to retire far earlier than the rest of the workforce.

The formula: (1.7% × High-3 × first 20 covered years) + (1.0% × High-3 × years beyond 20). At exactly 20 years that is 34% of your high-3. Every year after 20 adds only 1.0% — one reason many special-provision employees hit a wall of diminishing returns well before their mandatory age.

Worked example · 25 covered years

A LEO with a $140,000 high-3 and 25 covered years: (20 × 1.7%) + (5 × 1.0%) = 39% → $54,600/year for life, plus an immediate FERS supplement. That is why the first 20 years are worth so much more per year than anything after.

When you can retire

Special-provision eligibility is dramatically earlier than regular FERS — but only covered service counts toward these gates.

6(c) special-provision immediate retirement eligibility
Path	Age	Covered years
Age 50 + 20	50	20 covered
25 years, any age	Any	25 covered
Mandatory (LEO / firefighter)	57	20 covered
Mandatory (air traffic controller)	56	20 covered

Only 6(c)-covered service counts toward the 20- and 25-year thresholds. Unused sick leave and non-covered service add to your pension amount but not to eligibility. Source: OPM; 5 U.S.C. 8412(d), 8425.

The immediate FERS supplement

Unlike regular FERS retirees, special-provision retirees collect the FERS Special Retirement Supplement immediately — even before their Minimum Retirement Age. It approximates the Social Security you earned in federal service and bridges you to age 62.

Supplement ≈ (FERS years ÷ 40) × your estimated Social Security benefit at 62

The key advantage for 6(c) retirees: the supplement is exempt from the earnings test until you reach your MRA. You can take a second-career job right after retiring without losing supplement dollars, up to your MRA. After that, the standard test applies — $1 lost for every $2 earned over $24,480 (2026) — and the supplement ends at 62.

Why working past 20 hits special provisions hardest

Because the enhanced 1.7% rate is used up after year 20, every additional year earns only 1.0% — while the pension you forgo by not retiring keeps growing. At 25 covered years you are already giving up 39% of your high-3 in immediate pension (plus the supplement) to keep working. FedTools’ 2026 analysis puts the true cash reward for a special-provision employee’s marginal year at roughly half of salary or less — and it keeps falling each year, with a hard mandatory-age wall waiting at 56 or 57.
