### Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1865 would be equivalent to £1.06 in 1870, an absolute change of £0.06 and a cumulative change of 5.56%.

Compare these numbers to the US's overall absolute change of \$-0.20 and total percent change of -19.63%.

### 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 1865 and 1870.

Compare these values to the overall average of -4.28% per year:

Category Avg Inflation (%) Total Inflation (%) \$1 in 1865 → 1870
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00

### How to Calculate Inflation Rate for \$1, 1865 to 1870

This inflation calculator uses the following inflation rate formula:

CPI in 1870CPI in 1865
×
1865 USD value
=
1870 USD value

Then plug in historical CPI values. The U.S. CPI was 16.3 in the year 1865 and 13.1 in 1870:

13.116.3
×
\$1
=
\$0.80

\$1 in 1865 has the same "purchasing power" or "buying power" as \$0.80 in 1870.

To get the total inflation rate for the 5 years between 1865 and 1870, we use the following formula:

CPI in 1870 - CPI in 1865CPI in 1865
×
100
=
Cumulative inflation rate (5 years)

Plugging in the values to this equation, we get:

13.1 - 16.316.3
×
100
=
-20%

Politics and news often influence economic performance. Here's what was happening at the time:

• America abolishes slavery after Congress passes the 13th Amendment.
• John Wilkes Booth assassinates President Abraham Lincoln at Ford's Theater, in Washington.
• The New York Stock Exchange opens its first permanent headquarters at 10-12 Broad Street.
• Columbia, South Carolina burns during the American Civil War.
