ProAPOD has updated the Inflation Rate Calculator in Pro RE Calculator in accordance with government figures published Oct. 13. That means that users can now compute US annual inflation rates from 1913 through September 2020.


You spent $500 for college books in 1964 and want to know how much money you would have to spend in September 2020 to make that same purchase for books today. Here are the steps:

  • Login to Pro RE Calculator
