Understanding Inflation
Inflation, a fundamental economic concept dating back to ancient civilizations, represents the gradual increase in prices and consequent decrease in purchasing power over time. Our modern understanding of inflation emerged in the early 20th century, shaped by events like the Great Depression and post-war economic transformations.
Mathematical Foundation
FV = PV × (1 + r)^t
PPL = FV - PV
CI = (FV/PV - 1) × 100
- FV = Future Value
- PV = Present Value
- r = Annual Inflation Rate
- t = Time in Years
- PPL = Purchasing Power Loss
- CI = Cumulative Inflation
