What is purchasing power?

Purchasing power is the value of a currency expressed in terms of the quantity of goods and services that one unit of money can buy. It is a key concept in economics, reflecting the real value of money in everyday transactions.

When a currency’s purchasing power is high, consumers can buy more with the same amount of money. Conversely, when purchasing power is low, the same amount of money buys fewer goods and services.

Changes in purchasing power can impact wages, savings, and the pricing of goods and services.

Factors affecting purchasing power

Several factors influence purchasing power, including:

  • Inflation: An increase in the general price level of goods and services, leading to a decrease in purchasing power.
  • Deflation: A decrease in the general price level, resulting in an increase in purchasing power.
  • Currency exchange rates: Fluctuations in the value of a currency relative to others can impact purchasing power, especially for imported goods.
  • Income levels: Changes in income can affect an individual’s or household’s purchasing power.

Example of purchasing power in practice

Consider two scenarios: In 2000, a loaf of bread costs $1. In 2020, the same loaf of bread costs $2 due to inflation. If a person’s income remains the same over this period, their purchasing power has effectively decreased, as they can now buy fewer loaves of bread with the same amount of money.
