Inflation Calculator

A dollar today buys what 10 cents bought 100 years ago. Inflation is the silent killer of wealth. Our Inflation Calculator uses official Consumer Price Index (CPI) data from the U.S. Bureau of Labor Statistics, spanning from 1913 to the present, to show you exactly how much purchasing power your money has lost (or gained) over any period. Whether you are adjusting historical salaries, comparing investment returns, or planning for retirement, this tool provides the historical context you need.

How to Use the Inflation Calculator

• Forward Calculation: "What is $1,000 from 1980 worth in today's money?" Input 1980 as the start year, 2026 as the end year, amount $1,000. Result: Approximately $3,700. Your grandparents' $1,000 was equivalent to almost $4,000 today.
• Reverse Calculation: "What is today's $50,000 salary equivalent to in 1990?" Input 2026 as start, 1990 as end. Result: Approximately $22,000. You are earning more dollars, but your purchasing power relative to 1990 may have increased or decreased based on your actual salary.

Understanding CPI and Core Inflation

The CPI measures the average change in prices paid by urban consumers for a basket of goods and services (food, energy, housing, clothing, transportation). "Core Inflation" excludes volatile food and energy prices to show underlying trends. Our tool uses headline CPI for most calculations, but we provide a toggle to core CPI for economic analysis.

Why Inflation Matters for Investors

If your savings account earns 0.5% interest but inflation is 3.0%, your real return is -2.5%. You are losing purchasing power every year. Use our calculator to compute the "real return" on your investments. For example, if the S&P 500 returned 10% in a year, but inflation was 4%, your real return is 6%. This is why wealthy individuals invest in assets like real estate, stocks, and TIPS (Treasury Inflation-Protected Securities) that historically outpace inflation.

The Lost Decade: Hyperinflation Scenarios

In extreme cases (e.g., Weimar Germany, Zimbabwe, Venezuela), hyperinflation destroys currencies. Our calculator includes a "Hyperinflation Scenario" slider. Drag it to 100% monthly inflation (the hyperinflation definition). You'll see that $1,000 becomes worthless in months. This tool helps illustrate why hard assets like gold and Bitcoin are sometimes called "inflation hedges," though they carry their own risks.
