Disability retirement is sometimes called Chapter 61 retirement,
since the law governing such a retirement is in Chapter 61 of title 10
United States Code. Members who have been determined to be unfit for
duty with a disability rated by the military Service as 30% or greater
are eligible for disability retirement. A member whose condition is not
stable may be placed on the temporary disability retired list (TDRL) for
up to five years at which point they must be either discharged, retired
or returned to duty. Members whose condition has stabilized at a
disability rating of 30% or higher may be placed on the permanent
disability retired list (PDRL).
The basic retirement formula is:
Retired Pay Base X Multiplier %
The retired pay base for a qualified disability retirement is
determined under either the final pay method or the high-36 month method
depending upon when they first entered military service. See
Retirement tab for details.
The multiplier percentage is at the option of the member who may
chose either the percentage of disability assigned or the years of
creditable service times 2½%. In either case, the multiplier is limited
to 75% by law.
In the case of a member on the TDRL, the minimum percentage is 50% while on the TDRL.
The years of creditable service for computation of the retired pay
percentage multiplier include all active duty and all credited reserve
points divided by 360.
