Inflation Calculator

Inflation erodes purchasing power over time. This calculator shows how much a given amount will be worth in the future after accounting for inflation.

Key Terms

  • Inflation Rate — The annual percentage increase in prices (historical average ~3%).
  • Purchasing Power — The amount of goods/services a unit of currency can buy.
  • Real Value — Value adjusted for inflation.
  • Nominal Value — Face value without inflation adjustment.
  • Consumer Price Index (CPI) — The standard measure of inflation.

Inflation Formula

Future Value = Present Value × (1 + r)^n

Where:

  • r = Annual inflation rate
  • n = Number of years

Historical Inflation Rates

  • 1960s: ~2% average
  • 1970s: ~7% average (high inflation era)
  • 1980s-1990s: ~3-5%
  • 2000s-2010s: ~2% average
  • 2020s: ~3-4% (post-pandemic spike)

Tips for Protecting Against Inflation

  • Invest in assets that historically outpace inflation (stocks, real estate).
  • Consider Treasury Inflation-Protected Securities (TIPS).
  • Negotiate cost-of-living adjustments in employment contracts.
  • Lock in fixed-rate loans before rates rise.
  • Diversify investments across asset classes.
