## The Buying Power of $3,002 in 1917

We can look at the buying power equivalent for $3,002 in 1917 to see how much you would need to adjust for in order to beat inflation. For 1917 to 1975, if you started with $3,002 in 1917, you would need to have $12,617.78 in 1917 to keep up with inflation rates.

So if we are saying that $3,002 is equivalent to $12,617.78 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.

## Calculate Inflation Rate for $3,002 from 1917 to 1975

To calculate the inflation rate of $3,002 from 1917 to 1975, we use the following formula:

$$\dfrac{ 1917\; USD\; value \times CPI\; in\; 1975 }{ CPI\; in\; 1917 } = 1975\; USD\; value $$

We then replace the variables with the historical CPI values. The CPI in 1917 was 12.8 and 53.8 in 1975.

$$\dfrac{ \$3,002 \times 53.8 }{ 12.8 } = \text{ \$12,617.78 } $$

$3,002 in 1917 has the same purchasing power as $12,617.78 in 1975.

To work out the total inflation rate for the 58 years between 1917 and 1975, we can use a different formula:

$$ \dfrac{\text{CPI in 1975 } - \text{ CPI in 1917 } }{\text{CPI in 1917 }} \times 100 = \text{Cumulative rate for 58 years} $$

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

$$ \dfrac{\text{ 53.8 } - \text{ 12.8 } }{\text{ 12.8 }} \times 100 = \text{ 320.31\% } $$

## 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.
