Quick Definition

Inflation is the rate at which the general level of prices for goods and services rises over time, reducing purchasing power. It is measured by indices like the Consumer Price Index (CPI).

How Inflation Works

When inflation is 3%, something that costs $100 today will cost $103 next year. Over long periods, the effect compounds dramatically. At 3% annual inflation, prices double roughly every 24 years — so what costs $100 today would cost $200 in 2050.

Moderate inflation (2-3%) is considered healthy for an economy. The Federal Reserve targets 2% inflation as its benchmark. When inflation exceeds this target significantly, it erodes savings and reduces living standards.

What Causes Inflation

  • Demand-Pull: Too much money chasing too few goods (excess consumer demand)
  • Cost-Push: Rising production costs (energy, materials, wages) passed on to consumers
  • Monetary: Expansion of the money supply by central banks (printing money)

Real-World Example

Example

$100,000 in a savings account earning 1% interest with 3% inflation loses purchasing power every year. After 20 years, your $122,019 balance has the purchasing power of only $67,600 in today's dollars. Inflation silently eroded 32% of your wealth.

Frequently Asked Questions

How is inflation measured?

The most common measure is the Consumer Price Index (CPI), which tracks the average price change of a basket of goods and services including food, housing, transportation, and healthcare. The Bureau of Labor Statistics publishes CPI data monthly.

How can I protect my money from inflation?

Invest in assets that historically outpace inflation: stocks (average ~10%/year), real estate, Treasury Inflation-Protected Securities (TIPS), I-Bonds, and commodities. Keeping large amounts in low-yield savings accounts loses value to inflation.

What is the current inflation rate?

Inflation rates change monthly. Check the Bureau of Labor Statistics (bls.gov) for the latest CPI data. Use our Inflation Calculator to see how inflation affects your specific purchasing power over any time period.
