Method and common questions
Purpose and inputs
Estimate future purchasing power, the amount needed to preserve it and cumulative loss.
Method and assumptions
Future equivalent = amount×(1+inflation)^years; purchasing power = amount/(1+inflation)^years. Loss = (1−1/(1+inflation)^years)×100%. Deflation may produce a negative loss. This is a constant-rate illustration, not an inflation forecast.
