Inflation Purchasing Power
Inflation reduces purchasing power when prices rise. The same nominal amount buys less in the future when inflation compounds over time.
Core formula
Future nominal cost = current cost * (1 + inflation rate) ^ years
Real value = current amount / (1 + inflation rate) ^ years
