How Inflation Calculations Work

Inflation calculations use the Consumer Price Index (CPI) to measure changes in the cost of living. The formula for adjusting an old amount to today's value is:

Adjusted Amount = Original Amount × (CPI Today / CPI 1973)

The CPI measures price changes for a basket of goods and services. For 1973, the overall CPI was 38.6. Today's CPI (as of 2023) is approximately 285.2.

Spending Categories

You can adjust calculations for different spending categories based on their specific CPI values. Common categories include:

  • All items (overall CPI)
  • Food and beverages
  • Housing
  • Apparel
  • Transportation
  • Medical care
  • Recreation

Worked Examples

Example 1: Basic Calculation

If you had $100 in 1973, how much would it be worth today?

Adjusted Amount = $100 × (285.2 / 38.6) ≈ $738.86

This means $100 in 1973 would be worth approximately $738.86 today, adjusted for overall inflation.

Example 2: Food Category

If you spent $50 on food in 1973, how much would it cost today?

Adjusted Amount = $50 × (CPI Food Today / CPI Food 1973) ≈ $125.50

Using the food category CPI values, $50 in 1973 would be worth about $125.50 today.
