so im probably facing a situation where im not going to get a raise at work this year. (yeah i know cry me a river right

) Basically I want to go into my work review knowing how much inflation has affected my salary over the year. For instance, the salary I made this past year will not be worth as much next year because of inflation. SO id like to explain this to my boss so he will atleast give me a small raise to equal what last years salary was worth in the real world. If I dont get a raise im actually taking a pay cut do to inflation right? Sorry if that is confusing. Anyway, can anyone point me in the right direction to find out how much less the dollar is worth this year compared to last?
