Purchasing power decreased by 0.00% in 1891 compared to 1890. On average, you would have to spend 0.00% more money in 1891 than in 1890 for the same item.
In other words, $1 in 1890 is equivalent in purchasing power to about $1 in 1891.
The 1890 inflation rate was -1.09%. The inflation rate in 1891 was 0.00%. The 1891 inflation rate is lower compared to the average inflation rate of 2.64% per year between 1891 and 2019.
Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1891 was 9.10. It was 9.10 in the previous year, 1890. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.
|Average inflation rate||0.00%|
|Converted amount ($1 base)||$1|
|Price difference ($1 base)||$0.00|
|CPI in 1890||9.100|
|CPI in 1891||9.100|
|Inflation in 1890||-1.09%|
|Inflation in 1891||0.00%|
Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1890 would be equivalent to £1.01 in 1891, an absolute change of £0.01 and a cumulative change of 1.14%.
Compare these numbers to the US's overall absolute change of $0.00 and total percent change of 0.00%.
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 1890 and 1891.
Compare these values to the overall average of 0.00% per year:
|Category||Avg Inflation (%)||Total Inflation (%)||$1 in 1890 → 1891|
|Used cars and trucks||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 1890. This table and visualization use the earliest available data for each category.
This inflation calculator uses the following inflation rate formula:
Then plug in historical CPI values. The U.S. CPI was 9.1 in the year 1890 and 9.1 in 1891:
$1 in 1890 has the same "purchasing power" or "buying power" as $1 in 1891.
To get the total inflation rate for the 1 years between 1890 and 1891, we use the following formula:
Plugging in the values to this equation, we get:
To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1890, our investment would be nominally worth approximately $1.12 in 1891. This is a return on investment of 11.56%, with an absolute return of $0.12.
These numbers are not inflation adjusted, so they are considered nominal. In order to evaluate the real return on our investment, we must calculate the return with inflation taken into account.
The compounding effect of inflation would account for 0.00% of returns ($0.00) during this period. This means the inflation-adjusted real return of our $1 investment is $0.12.

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