This calculator is a handy way to figure out how the purchasing power of a dollar changes over time. You can use it to estimate the price increase needed to hold steady your return on products sold, rental property or other goods and services. You can also use it to figure out roughly how much more something bought in the past would cost today because of inflation.
Of course, the calculator can provide only an estimate of what inflation has done to your costs or prices, since it uses the Consumer Price Index for all goods and services for all consumers. Actual prices for some products and services rise much faster than for others, and inflation can vary from one region of the country to another. All data used are from the U.S. Bureau of Labor Statistics. Updated through 2009.
