## Calculate Inflation Rate for $90,466 from 1919 to 1999

To calculate the inflation rate of $90,466 from 1919 to 1999, we use the following formula:

$$\dfrac{ 1919\; USD\; value \times CPI\; in\; 1999 }{ CPI\; in\; 1919 } = 1999\; USD\; value $$

We then replace the variables with the historical CPI values. The CPI in 1919 was 17.3 and 166.6 in 1999.

$$\dfrac{ \$90,466 \times 166.6 }{ 17.3 } = \text{ \$871,192.81 } $$

$90,466 in 1919 has the same purchasing power as $871,192.81 in 1999.

To work out the total inflation rate for the 80 years between 1919 and 1999, we can use a different formula:

$$ \dfrac{\text{CPI in 1999 } - \text{ CPI in 1919 } }{\text{CPI in 1919 }} \times 100 = \text{Cumulative rate for 80 years} $$

Again, we can replace those variables with the correct Consumer Price Index values to work out the cumulativate rate:

$$ \dfrac{\text{ 166.6 } - \text{ 17.3 } }{\text{ 17.3 }} \times 100 = \text{ 863.01\% } $$

## Inflation Rate Definition

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. The value of the floating currency starts to decline when it becomes abundant. What this means is that the currency is not as scarce and, as a result, not as valuable.

By comparing a list of standard products (the CPI), the change in price over time will be measured by the inflation rate. The prices of products such as milk, bread, and gas will be tracked over time after they are grouped together. Inflation shows that the money used to buy these products is not worth as much as it used to be when there is an increase in these products’ prices over time.

The inflation rate is basically the rate at which money loses its value when compared to the basket of selected goods – which is a fixed set of consumer products and services that are valued on an annual basis.
