A price index can adjust a nominal amount to base-period purchasing-power units: nominal amount x 100 / index when the base index is 100. An index is a model of a chosen basket, not every person's exact costs. These figures are invented.

Worked example

At index 125, a nominal amount of 50 units becomes 50 x 100 / 125 = 40 base-period units.
