The Formula

Inflation calculations use these formulas:

Future Value = Initial × (1 + r)^n

Where:

  • Future Value = The equivalent amount in the end year
  • Initial = Starting amount
  • r = Annual inflation rate (as decimal)
  • n = Number of years
  • Total Inflation = ((Future - Initial) / Initial) × 100
  • Purchasing Power Lost = Initial - (Initial / (1 + r)^n)

Understanding Inflation and Purchasing Power

Inflation is the rate at which the general level of prices for goods and services rises, causing purchasing power to fall. Our inflation calculator helps you understand how much the value of money changes over time. Whether you're planning for retirement, analyzing historical investments, or simply trying to understand how prices have changed, this tool provides clear insights into the real value of money across different time periods. By calculating future values and purchasing power loss, you can make more informed financial decisions.
