If you're interested to see the effect of inflation on various amounts, the table below shows how much each amount would be worth today based on the price increase of We then replace the variables with the historical CPI values. The CPI in was To work out the total inflation rate for the 41 years between and , we can use a different formula:. Again, we can replace those variables with the correct Consumer Price Index values to work out the cumulativate rate:.
The inflation rate is the percentage increase in the average level of prices of a basket of selected goods over time. It indicates a decrease in the purchasing power of currency and results in an increased consumer price index CPI. Put simply, the inflation rate is the rate at which the general prices of consumer goods increases when the currency purchase power is falling.
The most common cause of inflation is an increase in the money supply, though it can be caused by many different circumstances and events.
To get the total inflation rate for the 41 years between and , we use the following formula:. The above data describe the CPI for all items. Also of note is the Core CPI , which measures inflation for all items except for the more volatile categories of food and energy. Core inflation averaged 3.
The average inflation rate of 3. As noted above, this yearly inflation rate compounds to produce an overall price difference of This is a return on investment of 11, These numbers are not inflation adjusted, so they are considered nominal. In order to evaluate the real return on our investment, we must calculate the return with inflation taken into account.
The compounding effect of inflation would account for Inflation data from to is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University. Ian Webster is an engineer and data expert based in San Mateo, California. He has worked for Google, NASA, and consulted for governments around the world on data pipelines and data analysis.
Disappointed by the lack of clear resources on the impacts of inflation on economic indicators, Ian believes this website serves as a valuable public tool. Ian earned his degree in Computer Science from Dartmouth College. Canada U. Australia Europe More Countries. Start year. End year. Inflation from to Cumulative price change All calculations are performed in the local currency USD and using 6 decimal digits. Results show only up to 2 decimal digits to favour readability.
Inflation data is provided by governments and international institutions on a monthly basis. Today's values were obtained by estimating figures from recent trends. There are several ways to calculate the time value of money. Depending on the data available, results can be obtained by using the compound interest formula or the Consumer Price Index CPI formula.
In this case, the future value represents the final amount obtained after applying the inflation rate to our initial value.
