### Inflation in 1745 and Its Effect on Dollar Value

Purchasing power increased by 4.17% in 1745 compared to 1744. On average, you would have to spend 4.17% less money in 1745 than in 1744 for the same item. This is an example of deflation.

In other words, \$1 in 1744 is equivalent in purchasing power to about \$0.96 in 1745.

The 1744 inflation rate was -7.69%. The inflation rate in 1745 was -4.17%. The 1745 inflation rate is lower compared to the average inflation rate of 1.48% per year between 1745 and 2020.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1745 was 4.60. It was 4.80 in the previous year, 1744. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1745 CPI is less than 1744 CPI, negative inflation (also known as deflation) has occurred.

### Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. This chart shows the average rate of inflation for select CPI categories between 1744 and 1745.

Compare these values to the overall average of -4.17% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1744 → 1745
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
Transportation 0.00 0.00 1.00
Medical care 0.00 0.00 1.00
Recreation 0.00 0.00 1.00
Education and communication 0.00 0.00 1.00
Other goods and services 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1744. This table and charts use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1744 to 1745

This inflation calculator uses the following inflation rate formula:

CPI in 1745CPI in 1744
×
1744 USD value
=
1745 USD value

Then plug in historical CPI values. The U.S. CPI was 4.8 in the year 1744 and 4.6 in 1745:

4.64.8
×
\$1
=
\$0.96

\$1 in 1744 has the same "purchasing power" or "buying power" as \$0.96 in 1745.

To get the total inflation rate for the 1 years between 1744 and 1745, we use the following formula:

CPI in 1745 - CPI in 1744CPI in 1744
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

4.6 - 4.84.8
×
100
=
-4%
