Inflation Calculator
See how inflation erodes purchasing power — what an amount today is equivalent to in the future at a given inflation rate.
Equivalent Future Amount
$13,439
- Purchasing power lost
- $3,439
Assumptions
- Assumes a constant annual inflation rate for the full period
How it's calculated
Future equivalent amount = amount × (1 + inflation rate)^years. Purchasing power loss = future equivalent amount − amount.
Worked example
$10,000 today, at 3% annual inflation over 10 years, is equivalent to a larger future amount, shown live above.
Frequently asked questions
Is the inflation rate guaranteed?
