20 C.F.R. § 416.413
The benefit under this part for a qualified individual (defined in § 416.221 ) is payable at the rate for an eligible individual or eligible couple plus an increment for each essential person (defined in § 416.222 ) in the household, reduced by the amount of countable income of the eligible individual or eligible couple as explained in § 416.420 . A qualified individual will receive an increment of $2,820 per year ($235 per month), effective for the period beginning January 1, 1996. This rate is the result of the 2.6 percent cost-of-living adjustment (see § 416.405 ) to the December 1995 rate, and is for each essential person (as defined in § 416.222 ) living in the household of a qualified individual. (See § 416.532 .) For the period January 1, through December 31, 1995, the rate payable, as increased by the 2.8 percent cost-of-living adjustment, was $2,748 per year ($229 per month). For the period January 1, through December 31, 1994, the rate payable, as increased by the 2.6 percent cost-of-living adjustment, was $2,676 per year ($223 per month). The total benefit rate, including the increment, is reduced by the amount of the individual's or couple's income that is not excluded pursuant to subpart K of this part.
