Analyze long-term inflation impact

This inflation calculator measures how purchasing power declines over time based on an expected inflation rate. It simulates the impact of inflation on cash holdings, indicating the visual gap between nominal values and real-world purchasing power. Reference historical inflation metrics via platforms like the Federal Reserve (FRED) to input average rate baselines.

Purchasing power loss

Even moderate inflation erodes cash value over long periods. A 3% annual rate cuts buying power by nearly 50% in 24 years.

Nominal vs Real returns

Always subtract inflation from your investment yields. A 7% nominal stock return is only a 4% real return if inflation stands at 3%.

Frequently Asked Questions

  • Inflation is the gradual increase in prices and fall in the purchasing value of money over time. It means that a unit of currency buys less than it did in the past.
  • Inflation is calculated as the annual percentage change in a Price Index, such as the Consumer Price Index (CPI), which tracks the cost of a representative basket of consumer goods.
  • Purchasing power is the value of a currency expressed in terms of the amount of goods or services that one unit of money can buy. Inflation directly erodes purchasing power.
  • Inflation is typically driven by demand-pull factors (demand outstripping supply), cost-push factors (rising production costs like wages and raw materials), or increases in the money supply.
  • You can protect your capital by investing in assets that historically outpace inflation, such as equities, real estate, commodities, or inflation-indexed bonds (like TIPS).
