In other words, \$1 in 1844 is equivalent in purchasing power to about \$1.01 in 1845.

The 1844 inflation rate was 1.35%. The inflation rate in 1845 was 1.33%. The 1845 inflation rate is lower compared to the average inflation rate of 2.04% per year between 1845 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1845 was 7.60. It was 7.50 in the previous year, 1844. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1844 would be equivalent to £1.04 in 1845, an absolute change of £0.04 and a cumulative change of 4.49%.

Compare these numbers to the US's overall absolute change of \$0.01 and total percent change of 1.33%.

### 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 1844 and 1845.

Compare these values to the overall average of 1.33% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1844 → 1845
Food 0.00 0.00 1.00
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 0.00 0.00 1.00
Medical care services 0.00 0.00 1.00
Medical care commodities 0.00 0.00 1.00

It's important to note that not all categories may be tracked since 1844. This table and visualization use the earliest available data for each category.

### How to Calculate Inflation Rate for \$1, 1844 to 1845

This inflation calculator uses the following inflation rate formula:

CPI in 1845CPI in 1844
×
1844 USD value
=
1845 USD value

Then plug in historical CPI values. The U.S. CPI was 7.5 in the year 1844 and 7.6 in 1845:

7.67.5
×
\$1
=
\$1.01

\$1 in 1844 has the same "purchasing power" or "buying power" as \$1.01 in 1845.

To get the total inflation rate for the 1 years between 1844 and 1845, we use the following formula:

CPI in 1845 - CPI in 1844CPI in 1844
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

7.6 - 7.57.5
×
100
=
1%
