U.S. inflation rate in 1886: -3.09%

Inflation in 1886 and its effect on dollar value

Purchasing power increased by 3.09% in 1886 compared to 1885. On average, you would have to spend 3.09% less money in 1886 than in 1885 for the same item. This is an example of deflation.

In other words, $1 in 1885 is equivalent in purchasing power to about $0.97 in 1886.

The 1885 inflation rate was -1.02%. The inflation rate in 1886 was -3.09%. The 1886 inflation rate is lower compared to the average inflation rate of 2.50% per year between 1886 and 2020.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1886 was 9.40. It was 9.70 in the previous year, 1885. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1886 CPI is less than 1885 CPI, negative inflation (also known as deflation) has occurred.

Converted amount ($1 base) $0.97
Price difference ($1 base) $-0.03
CPI in 1885 9.700

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1885 would be equivalent to £0.99 in 1886, an absolute change of £-0.01 and a cumulative change of -1.14%.

Compare these numbers to the US's overall absolute change of $-0.03 and total percent change of -3.09%.

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 1885 and 1886.

Compare these values to the overall average of -3.09% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1885 → 1886
Food and beverages 0.00 0.00 1.00
Housing 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
Transportation 0.00 0.00 1.00
Medical care 0.00 0.00 1.00
Recreation 0.00 0.00 1.00
Education and communication 0.00 0.00 1.00
Other goods and services 0.00 0.00 1.00

For all these visualizations, it's important to note that not all categories may have been tracked since 1885. This table and charts use the earliest available data for each category.

How to Calculate Inflation Rate for $1, 1885 to 1886

Our calculations use the following inflation rate formula to calculate the change in value between 1885 and 1886:

CPI in 1886 CPI in 1885
1885 USD value
1886 USD value

Then plug in historical CPI values. The U.S. CPI was 9.7 in the year 1885 and 9.4 in 1886:


$1 in 1885 has the same "purchasing power" or "buying power" as $0.97 in 1886.

To get the total inflation rate for the 1 years between 1885 and 1886, we use the following formula:

CPI in 1886 - CPI in 1885CPI in 1885
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

9.4 - 9.79.7

Comparison to S&P 500 Index

To help put this inflation into perspective, if we had invested $1 in the S&P 500 index in 1885, our investment would be nominally worth approximately $1.46 in 1886. This is a return on investment of 45.61%, with an absolute return of $0.46 on top of the original $1.

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 -3.19% of returns ($-0.05) during this period. This means the inflation-adjusted real return of our $1 investment is $0.50. You may also want to account for capital gains tax, which would take your real return down to around $0 for most people.

Investment in S&P 500 Index, 1885-1886
Original Amount Final Amount Change
Nominal $1 $1.46 45.61%
Inflation Adjusted
$1 $1.50 50.26%

Information displayed above may differ slightly from other S&P 500 calculators. Minor discrepancies can occur because we use the latest CPI data for inflation, annualized inflation numbers for previous years, and we compute S&P price and dividends from January of 1885 to latest available data for 1886 using average monthly close price.

News headlines from 1885

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

  • King Leopold II of Belgium makes Congo his own personal, colonial possession.
  • Congo is given to Belgium whilst Nigeria is awarded to Great Britain during the Berlin Conference
  • Bismarck, German chancellor, conquers Cameron and Togoland
  • Louis Pasteur conducts the first successful test of an anti-rabies vaccine
  • Gottlieb Daimler invents the first motorcycle.
