Every tax imposed by this chapter shall be automatically increased each year by a percentage which shall be equal to the percentage increase of the consumer price index as shall be reflected in the most recent report of consumer prices for the San Francisco/Bay Area Standard Metropolitan Statistical Area using 1992 as the base year. The annual rate increase shall be calculated by dividing the consumer price index for October of each current year by the base year with the resulting figure representing the percentage increase for the tax due the following January. The formula shall be as follows:
A divided by B times C equals D
A = current year CPI; B = base year CPI;
C = base year tax rate; D = current year tax rate
