The amount payable to a member in any limitation year, including cost-of-living adjustments provided under this chapter, shall not exceed the limit applicable under Section 415(b) of the Internal Revenue Code at the annuity starting date, as increased in subsequent years pursuant to Section 415(d) of the Internal Revenue Code and the associated regulations.

Nothing in this section is intended to, nor shall be construed to, entitle a retired member to an adjustment to their allowance in excess of that provided pursuant to this chapter.

(c) Nothing in this section shall change the formula used to calculate benefits under this chapter.
