The minimum wage is determined by taking the current minimum wage of $8.65 and increasing it by the CPI-U increase from August of 2019 to August 2020. The CPI-U increased by 1.31% (unadjusted) over the year ending August 2020. To keep the minimum wage at the same purchasing power as the prior year, the wage should increase by $0.11 per hour. However, since state statute requires the wage to rounded to the nearest 5 cents, the 2021 minimum wage rate will be $8.75. 

In 2020, the District of Columbia and 29 U.S. states, including Montana, have minimum wage rates that exceed the federal rate of $7.25 per hour.
