1. What is Buying Power Inflation?

Buying power refers to the amount of goods or services that a unit of currency can purchase. Inflation reduces buying power over time as prices rise. This calculator shows how much a past amount of money would be worth in today's dollars after accounting for inflation.

2. How Does the Calculator Work?

The calculator uses the buying power formula:

Where:

• Past Amount — The original amount of money
• Inflation — Annual inflation rate (as percentage)
• t — Number of years

Explanation: The formula accounts for the compounding effect of inflation over time, showing how much purchasing power has been lost.
