## The Buying Power of $21,192 in 1947

We can look at the buying power equivalent for $21,192 in 1947 to see how much you would need to adjust for in order to beat inflation. For 1947 to 1964, if you started with $21,192 in 1947, you would need to have $29,459.73 in 1947 to keep up with inflation rates.

## Calculate Inflation Rate for $21,192 from 1947 to 1964

To calculate the inflation rate of $21,192 from 1947 to 1964, we use the following formula:

$$\dfrac{ 1947\; USD\; value \times CPI\; in\; 1964 }{ CPI\; in\; 1947 } = 1964\; USD\; value $$

We then replace the variables with the historical CPI values. The CPI in 1947 was 22.3 and 31 in 1964.

$$\dfrac{ \$21,192 \times 31 }{ 22.3 } = \text{ \$29,459.73 } $$

$21,192 in 1947 has the same purchasing power as $29,459.73 in 1964.

To work out the total inflation rate for the 17 years between 1947 and 1964, we can use a different formula:

$$ \dfrac{\text{CPI in 1964 } - \text{ CPI in 1947 } }{\text{CPI in 1947 }} \times 100 = \text{Cumulative rate for 17 years} $$

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

$$ \dfrac{\text{ 31 } - \text{ 22.3 } }{\text{ 22.3 }} \times 100 = \text{ 39.01\% } $$

## 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.
