How Inflation Is Measured

Consumer Price Index (CPI)

The CPI tracks the average change in prices paid by urban consumers for a basket of goods and services including food, housing, transportation, and medical care. The Bureau of Labor Statistics publishes it monthly.

Inflation rate = ((CPInew − CPIold) ÷ CPIold) × 100

Purchasing Power

Purchasing power measures what your money can actually buy. As prices rise, each dollar buys less. To find what past money is worth today, multiply by the ratio of current to past CPI.

Today's value = Amount × (CPItoday ÷ CPIthen)

Example: $1,000 in 2010 → $1,000 × (315 ÷ 218) = $1,467

Why Inflation Matters for Investing

If your investments don't outpace inflation, you're losing purchasing power even if your balance grows. A savings account earning 1% while inflation is 3% means you're losing 2% in real terms every year.

Real return = Nominal return − Inflation rate

S&P 500 avg: ~10% nominal − ~3% inflation = ~7% real
