About this calculator

Data available as: CSV, JSON and XML

This calculator uses monthly consumer price index (CPI) data from 1914 to the present to show changes in the cost of a fixed "basket" of consumer purchases. These include:

  • food
  • shelter
  • furniture
  • clothing
  • transportation
  • recreation

An increase in this cost is called inflation.

The results shown are based on the most recent month for which the CPI data are available. This will normally be about two months prior to the current month.

The equation to compute the current cost is as follows: $$\$Cost_2 = \$Cost_1 * (\frac{CPI_2}{CPI_1})$$ The equation to compute the percentage change is as follows: $$\%Change = (\frac{\$Cost_2 - \$Cost_1}{\$Cost_1}) * 100$$
