Quick Summary

Purchasing power refers to the value of money in terms of how much it can buy. It can be understood in two ways: the amount of money available to spend, and the actual value of that money in terms of goods and services. Inflation, for example, decreases purchasing power because the same amount of money buys fewer goods over time.12

A related concept is Purchasing Power Parity (PPP), which compares the value of currencies by looking at the prices of a fixed basket of goods and services in different countries. PPP is useful for more accurate comparisons of economic output and living standards between nations than market exchange rates, which can be volatile. An inflation calculator can help visualize how purchasing power changes over time by adjusting for price increases.32
