PVM = PV / (1 + IR)^T
  • Where PVM is the past value of the money ($)
  • PV is the present value ($)
  • IR is the inflation or interest rate (decimal)
  • T is the number of years in the past

To calculate the past value of money, divide the present value by (1 plus the inflation or interest rate) raised to the power of the number of years.

How to Calculate Past Value Of Money?

Example Problem:

The following example outlines the steps and information needed to calculate the Past Value Of Money.

First, determine the present-day amount of money. In this example, the amount is $10,000.

Next, determine the average inflation or interest rate, as well as the number of years in the past you want to calculate. In this scenario, the rate is 3%, and the time period is 5 years.

Finally, calculate the past value using the formula above:

PVM = PV / (1 + IR)^T

PVM = $10,000 / (1 + .03)^5

PVM ≈ $8,626.09
