Understanding the results
The summary separates the most important output from supporting values. Currency selection changes formatting only; it does not convert exchange rates or alter a currency-independent formula.

Purchasing power is the present amount divided by the same inflation factor. The result depends on the values and assumptions entered, so compare it with the applicable provider or official rule.
