With the consumer price index we’re able to compare prices and salaries from year to year.
Let’s say your grandmother made $15,000 per year in 1964 and your mother makes $37,000 per year in 2010 and you want to know if your grandmother made more or less than your mother. You can convert grandma’s actual $15,000 salary to 2010 Constant Dollars and see if it’s higher or lower than your mother’s.

Since the value of the dollar decreased each year, this graph is not a realistic depiction of your salary over this period.
Constant Dollar Salary is not represented

Scenario for Electricity
We saw what the graph looked like when the constant dollar price of Electricity went down relative to the rate of inflation.
What would the constant dollar graph look like if electricity increased at the same rate as inflation?
