$1 in 1797 is equivalent in purchasing power to about $0.97 in 1798.
The dollar had an average **deflation** rate of -3.15% per year since 1797, producing a cumulative price change of -3.15%.
Purchasing power *increased* by 3.15% in 1798 compared to 1797. On average, you would have to spend 3.15% *less* money in 1798 than in 1797 for the same item.
This is an example of **deflation**.

This means that prices in 1798 are 3.15% lower than average prices since 1797, according to the Bureau of Labor Statistics consumer price index.

The 1797 inflation rate was -3.79%. The inflation rate in 1798 was -3.15%. The 1798 inflation rate is lower compared to the average inflation rate of 1.41% per year between 1798 and 2021.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1798 was 12.30. It was 12.70 in the previous year, 1797. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1798 CPI is less than 1797 CPI, negative inflation (also known as deflation) has occurred.

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1797 would be equivalent to £0.98 in 1798, an absolute change of £-0.02 and a cumulative change of -2.22%.

Compare these numbers to the US's overall absolute change of $-0.03 and total percent change of -3.15%.

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 1797 and 1798.

Compare these values to the overall average of -3.15% per year:

Category | Avg Inflation (%) | Total Inflation (%) | $1 in 1797 → 1798 |
---|---|---|---|

Food and beverages | 0.00 | 0.00 | 1.00 |

Housing | 0.00 | 0.00 | 1.00 |

Apparel | 0.00 | 0.00 | 1.00 |

For all these visualizations, it's important to note that not all categories may have been tracked since 1797. This table and charts use the earliest available data for each category.

Our calculations use the following inflation rate formula to calculate the change in value between 1797 and 1798:

$1 in 1797 has the same "purchasing power" or "buying power" as $0.97 in 1798.

To get the total inflation rate for the 1 years between 1797 and 1798, we use the following formula:

CPI in 1798 - CPI in 1797CPI in 1797

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

- Napoleon prepares plans to invade Britain.
- First £1 note issued by the Bank of England
- The Dutch fleet is defeated by British navy in a Battle of Camperdown

Raw data for these calculations comes from the Bureau of Labor Statistics' Consumer Price Index (CPI), established in 1913. Inflation data from 1665 to 1912 is sourced from a historical study conducted by political science professor Robert Sahr at Oregon State University.
