Inflation Calculator
See how inflation erodes purchasing power over time - and how much you'd need in the future to buy what today's money buys now.
Equivalent value in 20 years
$18,061.11
What Your Result Means
The equivalent future value shows how much money you'd need at a future date to have the same purchasing power as your amount today, given a constant inflation rate. Purchasing power lost shows how much less today's amount would be able to buy by that future date.
How It Is Calculated
Future Amount Needed = Current Amount × (1 + Inflation Rate)^Years
Worked Example
At 3% average annual inflation, $10,000 today would need to grow to about $18,061 in 20 years just to maintain the same purchasing power - meaning today's $10,000 will feel like roughly $5,537 in today's dollars by then.
Important Assumptions
- Assumes a constant inflation rate - real inflation varies year to year and by spending category.
