purchasing power
The value of money expressed in terms of the goods and services it can buy.
Example
“Inflation eroded her purchasing power — the same $100 bought less each year.”
Memory Tip
PURCHASING POWER = the POWER to PURCHASE. Inflation weakens it; deflation strengthens it.
Why It Matters
Understanding purchasing power helps you make better financial decisions because it shows how inflation affects what your money can actually buy over time. If you do not account for purchasing power, you might think you are saving money when in reality inflation is silently eroding the value of your savings.
Common Misconception
Many people believe that having more money automatically means they are wealthier, but purchasing power reveals this is not always true. If inflation rises faster than your salary, you actually have less purchasing power even though you earn more dollars than before.
In Practice
Imagine you had $20,000 in 2010 and $25,000 in 2024. While the second number seems bigger, if inflation has reduced the purchasing power of the dollar by 30 percent over that time, your $25,000 in 2024 can buy roughly the same amount of goods as $17,500 in 2010, meaning your real wealth actually decreased despite earning more money.
Etymology
Purchasing (the act of buying) + power (ability) — the ability to buy things with money.
