How this calculator works
Future cost is today's amount × (1 + inflation rate) for each year. Buying power works the other way: today's amount divided by the same factor shows what it will buy in today's dollars.
Worked example
With the example values below: Future cost, $134.39 (what costs $100.00 today). Change any number above to run your own.
What you enter
| Input | Example |
