If the index number rises excessively, it means that the cost of living is rising and therefore we have inflation, which in turn causes the Federal Reserve to take appropriate measures to control it. Having said that, it is important not to get too concerned about the monthly changes in the CPI. Rather, as a whole, we must look at the changes over a longer period such as a few months or a year. This is important because seasonal price changes tend to cause temporary fluctuation in the price of goods without necessarily creating inflation! As much as the Index tries to adjust for those changes it is better to look at the CPI over a long period of time such as one year to get the most accurate inflation reading. (Our index figure used in this calculator is the average of the 12 reported monthly figures, for the year's figure.) The CPI is used by the federal reserve when deciding the changes that need to be made to the interest rates as well as by investors when trying to predict the future price of securities. Indeed, when inflation is rising, it causes people to buy less goods, therefore reducing the profits of major companies (such as Ford, Wal-Mart, and similar). This loss of profit in turns causes the company's stock prices to drop as well. This shows how important it is to monitor the Consumer Price Index whether you are an individual investor, a member of the federal Reserve Board or simply someone who is trying to estimate future costs and spending. The CPI is reported monthly by the government, however, it is often adjusted, as far back as several years based on new information. Our data is adjusted as we get new information from the government. The 2005 CPI is based on the average monthly figures until the annual figure is posted.
To use the CPI Calculator, enter a cost, valued in your From (Base) year. Select both the From year and the To year for the calculation. Click on Calculate (or any other box) and the CPI information will be returned. You may change a value and recalculate or click on Clear Values to start over. For the years in our database, if you wish to see what a dollar in 1930 was worth is 2000, enter $1.00 as the Exemplary Cost, 1930 in the From (Base) and 200 in the To (Target). Then click on Calculate.
