Inflation in 1900 and Its Effect on Dollar Value

Purchasing power decreased by 1.20% in 1900 compared to the previous year, 1899. On average, you would have to spend 1.20% more money in 1900 than in 1899 for the same item.

In other words, $100 in 1899 is equivalent in purchasing power to $101.20 in 1900.

The 1899 inflation rate was 0.00%. The inflation rate in 1900 was 1.20%. The 1900 inflation rate is lower compared to the average inflation rate of 2.92% per year between 1900 and 2018.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1900 was 8.4. It was 8.3 in the previous year, 1899. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation.

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £100.00 in 1899 would be equivalent to £104.55 in 1900, an absolute change of £4.55 and a cumulative change of 4.55%.

Compare these numbers to the US's overall absolute change of $1.20 and total percent change of 1.20%.


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 1899 and 1900.

Compare these values to the overall average of 1.20% per year:

Category Avg Inflation (%) Total Inflation (%) $100 in 1899 → 1900
Food 0.00 0.00 100.00
Shelter 0.00 0.00 100.00
Energy 0.00 0.00 100.00
Apparel 0.00 0.00 100.00
New vehicles 0.00 0.00 100.00
Used cars and trucks 0.00 0.00 100.00
Transportation services 0.00 0.00 100.00
Medical care services 0.00 0.00 100.00
Medical care commodities 0.00 0.00 100.00

It's important to note that not all categories may be tracked since 1899. This table and visualization use the earliest available data for each category.



How to Calculate Inflation Rate for $100, 1899 to 1900

This inflation calculator uses the following inflation rate formula:

CPI in 1900CPI in 1899
×
1899 USD value
=
1900 USD value

Then plug in historical CPI values. The U.S. CPI was 8.3 in the year 1899 and 8.4 in 1900:

8.48.3
×
$100
=
$101.20

$100 in 1899 has the same "purchasing power" or "buying power" as $101.20 in 1900.

To get the total inflation rate for the 1 years between 1899 and 1900, we use the following formula:

CPI in 1900 - CPI in 1899CPI in 1899
×
100
=
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

8.4 - 8.38.3
×
100
=
1%

Comparison to S&P 500 Index

To help put this inflation into perspective, if you had invested $100 in the S&P 500 index in 1899, your investment would be worth approximately $125.23 in 1900. This is a change of 25.23%.

This means the nominal return on a $100 investment is $25.23, but inflation would eat into your real returns.

Inflation would account for 1.19% of your returns ($0.30), for an inflation-adjusted real return of about $24.93.
