Why points, not years
A traditional part-time Guard or Reserve year — one weekend a month plus two weeks of annual training — typically earns somewhere around 50 to 80 retirement points, well short of the 360 points that represent a full year of active duty. The formula divides your career point total by 360 to get "equivalent years," which is almost always a much smaller number than your actual calendar years of service. A 20-year career with modest point accrual can produce only a handful of equivalent years — that gap is how the system is designed to work, not a mistake in the math.
When this pay can start
Reserve/Guard non-regular retired pay normally begins at age 60. If you performed qualifying active duty after January 28, 2008, each aggregate 90 days shaves 3 months off that start age, down to a floor of 50 — so significant post-9/11 mobilization time can move your start date up by several years. Enter your qualifying active-duty days above to see your own reduced age.
Keeping this pay while buying back your active-duty years
A common misconception is that any military pension has to be waived to also get FERS credit for the same time. That's true for a regular 20-year active-duty pension — but 5 U.S.C. § 8411(c)(2) specifically exempts Reserve/Guard non-regular retired pay (and disability-based retired pay) from that waiver requirement. You can keep this pay in full and still make a buyback deposit for your active-duty periods toward a separate FERS civilian pension. See the Military Buyback Calculator to price that out.
VA disability compensation
VA disability compensation — including Special Monthly Compensation for more severe conditions — is a separate, independent benefit. It's tax-free at both the federal and state level, and it doesn't reduce either your Reserve/Guard retired pay or a FERS annuity; it simply adds on top. Because SMC and combined-rating amounts vary considerably and the VA's own rate tables change periodically, enter your own monthly figure from your award letter rather than a disability percentage.
