b. Said cost-of-living adjustment shall be a percentage of the annual retirement allowance otherwise payable, computed without optional modification, excluding any annuity derived from voluntary contributions made by members, except those made pursuant to elections under subdivision one of section five hundred eleven-a or paragraph c of subdivision three of section five hundred sixteen of this article, but including any benefit derived from subdivision f of this section and any prior year's cost-of-living adjustment derived from this section.

Said percentage shall equal fifty percent of the annual inflation, as determined from the increase in the consumer price index in the one year period ending on the March thirty-first prior to the cost-of-living adjustment effective on the ensuing September first.
