Enter the current price ($) and the inflation rate (%) into the Reverse Inflation Calculator. The calculator will evaluate and display the initial price before inflation.

Reverse Inflation Formula

The following formula is used to calculate the Reverse Inflation. 

IP = CP / (1+R/100)
  • Where IP is the initial price before inflation ($)
  • CP is the current price ($) 
  • R is the inflation rate (%) 

How to Calculate Reverse Inflation?

The following example problems outline how to calculate Reverse Inflation.

Example Problem #1:

  1. First, determine the current price ($).
    • The current price ($) is given as: 500.
  2. Next, determine the inflation rate (%).
    • The inflation rate (%) is provided as: 10.
  3. Finally, calculate the Reverse Inflation using the equation above: 

IP = CP / (1+R/100)

The values given above are inserted into the equation below and the solution is calculated:

IP = 500 / (1+10/100) = 454.54 ($)


What is inflation and how does it affect purchasing power?

Inflation is the rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling. Central banks attempt to limit inflation, and avoid deflation, in order to keep the economy running smoothly. As inflation increases, the value of money decreases, meaning consumers can purchase less with the same amount of money over time.

Why is understanding reverse inflation important?

Understanding reverse inflation is crucial for investors, economists, and consumers to determine the real value of money over time. It helps in making informed decisions about investments, savings, and expenditures by calculating the initial price of a good or service before it was affected by inflation. This can also aid in understanding economic trends and the health of an economy.

Can reverse inflation be used to predict future inflation rates?

While reverse inflation calculations provide insight into past inflation rates and the initial value of money, predicting future inflation rates requires a more complex analysis of current economic conditions, policies, and trends. Reverse inflation calculations can be part of this analysis but should be used in conjunction with other economic indicators to forecast future inflation rates accurately.
