COMMON QUESTIONS
Frequently Asked Questions
Purchasing power and inflation indexes explained? What is inflation?
Inflation is the general increase in prices and fall in the purchasing value of money over a given period, typically calculated annually.
? How does inflation erode purchasing power?
As prices rise, a single unit of currency buys a smaller percentage of goods or services. This effectively lowers the real value of cash savings.
? What is the CPI (Consumer Price Index)?
CPI is a primary macroeconomic indicator measuring the average change over time in the prices paid by consumers for a market basket of goods.
? How is future inflation-adjusted cost calculated?
We use compounding growth math: Future Cost = Current Cost * (1 + inflation_rate)^years. For example, at 3% inflation, $100 in 20 years costs $180.61.
? Does the inflation tool support custom rates?
Yes, you can input any historical or customized target inflation rate (e.g. 2%, 6%, or hyperinflation rates) to project custom scenarios.
