How do I determine real vs. nominal income for real life use?

I've taken 3 college econ classes, but I don't know where my notes are about how to do this. I'm not currently in class; I want to know how to do this so I can figure out if pay raises are advancing me past inflation and to be able to compare what I was making in previous years to the current year.

If I'm making a certain hourly wage, and I want to compare that to a different hourly wage (for ex. pay raise) or a different year's inflation rate (for example, to see how much I should be making now to be breaking even with what I was making before), how do I figure that? And where online do I find accurate info to use for inflation between years? Thank you very much for your help!
