FAQs
What is included in this estimate?
The calculator focuses on estimated future equivalent cost, purchasing power loss percentage, and absolute value difference versus today.
Can I compare multiple scenarios?
Yes. Change one input at a time and compare estimated future equivalent cost and purchasing power loss percentage.
Can I treat this as a final legal or financial quote?
No. The model uses assumptions such as: Country-specific baskets and policy shocks are not included.
Is this an official inflation forecast?
No. It is a fixed-rate estimate to compare practical scenarios.
Worked example
Example: $100 today at 3% inflation for 10 years
Input: Amount: $100; Inflation: 3%; Period: 10 years
Output: Future equivalent cost: about $134.39; Loss: about 25.6%
Note: Use multiple rates (for example 2%, 4%, 6%) to test sensitivity.
