Washington State’s minimum wage increases 15 cents to $9.47 an hour beginning Jan. 1, 2015.

The increase reflects a 1.59 percent growth in the federal Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) over the 12 month period ending Aug. 31.

The state Department of Labor and Industries calculates the state’s minimum wage each year as required under Initiative 688, which was approved by Washington voters in 1998.
