If an economist's job paid $50,000 a year 10 years ago, how would understanding the present value and future value of money help explain the difference in the pay rate for the same job today?

Present value and future value account for how money’s purchasing power changes over time. Comparing the $50,000 salary from 10 years ago with today’s salary in this way helps show how economic changes, such as inflation, affect the pay rate. It does not guarantee a yearly raise or prove the salary has more than doubled.
