$9 in 1944 has the same purchasing power as $9.20 in 1945. Over the 1 year this is a change of $0.20.

The average inflation rate of the dollar between 1944 and 1945 was 2.00% per year. The cumulative price increase of the dollar over this time was 2.27%.

## The value of $9 from 1944 to 1945

So what does this data mean? It means that the prices in 1945 are 0.09 higher than the average prices since 1944. A dollar in 1945 can buy 97.78% of what it could buy in 1944.

These inflation figures use the Bureau of Labor Statistics (BLS) consumer price index to calculate the value of $9 between 1944 and 1945.

The inflation rate for 1944 was 1.73%, while the inflation rate for 1945 was 2.27%. The 1945 inflation rate is lower than the average inflation rate of 3.65% per year between 1945 and 2021.

## The Buying Power of $9 in 1944

We can look at the buying power equivalent for $9 in 1944 to see how much you would need to adjust for in order to beat inflation. For 1944 to 1945, if you started with $9 in 1944, you would need to have $9.20 in 1944 to keep up with inflation rates.

So if we are saying that $9 is equivalent to $9.20 over time, you can see the core concept of inflation in action. The "real value" of a single dollar decreases over time. It will pay for fewer items at the store than it did previously.

In the chart below you can see how the value of the dollar is worth less over 1 year.

## Value of $9 Over Time

## Calculate Inflation Rate for $9 from 1944 to 1945

To calculate the inflation rate of $9 from 1944 to 1945, we use the following formula:

$$\dfrac{ 1944\; USD\; value \times CPI\; in\; 1945 }{ CPI\; in\; 1944 } = 1945\; USD\; value $$

We then replace the variables with the historical CPI values. The CPI in 1944 was 17.6 and 18 in 1945.

$$\dfrac{ \$9 \times 18 }{ 17.6 } = \text{ \$9.20 } $$

$9 in 1944 has the same purchasing power as $9.20 in 1945.

To work out the total inflation rate for the 1 year between 1944 and 1945, we can use a different formula:

$$ \dfrac{\text{CPI in 1945 } - \text{ CPI in 1944 } }{\text{CPI in 1944 }} \times 100 = \text{Cumulative rate for 1 year} $$

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

$$ \dfrac{\text{ 18 } - \text{ 17.6 } }{\text{ 17.6 }} \times 100 = \text{ 2.27\% } $$

## 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.
