About this inflation calculator
An inflation calculator shows why long-term investing matters: prices rise, so cash under the mattress loses purchasing power.
How to use
- Enter today's amount, assumed inflation rate, and years ahead.
- Compare future cost vs today's purchasing power.
Formula
Future value = Amount × (1 + rate)years
Worked examples
Example: $1,000 at 3% inflation for 10 years → future cost ≈ $1,344.
Tips
- Use a long-run average inflation rate for planning, not a single spike month.
