Buying power of $1 in 1770

This chart shows a calculation of buying power equivalence for $1 in 1770 (price index tracking began in 1635).

For example, if you started with $1, you would need to end with $1.05 in order to "adjust" for inflation (sometimes refered to as "beating inflation").

When $1 is equivalent to $1.05 over time, that means that the "real value" of a single U.S. dollar decreases over time. In other words, a dollar will pay for fewer items at the store.

This effect explains how inflation erodes the value of a dollar over time. By calculating the value in 1770 dollars, the chart below shows how $1 is worth less over 3 years.

According to the Bureau of Labor Statistics, each of these USD amounts below is equal in terms of what it could buy at the time:

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1770 would be equivalent to £1.19 in 1773, an absolute change of £0.19 and a cumulative change of 19.35%.

Compare these numbers to the US's overall absolute change of $0.05 and total percent change of 4.88%.


Inflation by Spending Category

CPI is the weighted combination of many categories of spending that are tracked by the government. Breaking down these categories helps explain the main drivers behind price changes.

This chart shows the average rate of inflation for select CPI categories between 1770 and 1773.

Compare these values to the overall average of 1.60% per year:

How to calculate inflation rate for $1, 1770 to 1773

Our calculations use the following inflation rate formula to calculate the change in value between 1770 and 1773:

CPI in 1773 CPI in 1770
×
1770 USD value
=
1773 USD value

Then plug in historical CPI values. The U.S. CPI was 8.2 in the year 1770 and 8.6 in 1773:

8.68.2
×
$1
=
$1.05

$1 in 1770 has the same "purchasing power" or "buying power" as $1.05 in 1773.

To get the total inflation rate for the 3 years between 1770 and 1773, we use the following formula:

CPI in 1773 - CPI in 1770CPI in 1770
×
100
=
Cumulative inflation rate (3 years)

Plugging in the values to this equation, we get:

8.6 - 8.28.2
×
100
=
5%
