Compute how a fixed sum's purchasing power erodes over time at a given inflation rate: realValue=nominal/(1+i)^years, plus the nominal amount needed to preserve today's buying power. Answers 'what will $10000 be worth in 10 years at 3% inflation', 'how much purchasing power do I lose to inflation', 'nominal amount to keep up with inflation'.
