Inflation Calculator


Inflation in 1877 and Its Effect on Dollar Value

Purchasing power increased by 1.87% in 1877 compared to 1876. On average, you would have to spend 1.87% less money in 1877 than in 1876 for the same item. This is an example of deflation.

In other words, $1 in 1876 is equivalent in purchasing power to about $0.98 in 1877.

The 1876 inflation rate was -2.73%. The inflation rate in 1877 was -1.87%. The 1877 inflation rate is lower compared to the average inflation rate of 2.27% per year between 1877 and 2019.

Inflation rate is calculated by change in the consumer price index (CPI). The CPI in 1877 was 10.50. It was 10.70 in the previous year, 1876. The difference in CPI between the years is used by the Bureau of Labor Statistics to officially determine inflation. Because the 1877 CPI is less than 1876 CPI, negative inflation (also known as deflation) has occurred.

Converted amount ($1 base) $0.98
Price difference ($1 base) $-0.02
CPI in 1876 10.700
CPI in 1877 10.500

Inflation by Country

Inflation can also vary widely by country. For comparison, in the UK £1.00 in 1876 would be equivalent to £0.99 in 1877, an absolute change of £-0.01 and a cumulative change of -1.02%.

Compare these numbers to the US's overall absolute change of $-0.02 and total percent change of -1.87%.

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 1876 and 1877.

Compare these values to the overall average of -1.87% per year:

Category Avg Inflation (%) Total Inflation (%) $1 in 1876 → 1877
Food 0.00 0.00 1.00
Shelter 0.00 0.00 1.00
Energy 0.00 0.00 1.00
Apparel 0.00 0.00 1.00
New vehicles 0.00 0.00 1.00
Used cars and trucks 0.00 0.00 1.00
Transportation services 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 1876. This table and visualization use the earliest available data for each category.

How to Calculate Inflation Rate for $1, 1876 to 1877

This inflation calculator uses the following inflation rate formula:

CPI in 1877CPI in 1876
1876 USD value
1877 USD value

Then plug in historical CPI values. The U.S. CPI was 10.7 in the year 1876 and 10.5 in 1877:


$1 in 1876 has the same "purchasing power" or "buying power" as $0.98 in 1877.

To get the total inflation rate for the 1 years between 1876 and 1877, we use the following formula:

CPI in 1877 - CPI in 1876CPI in 1876
Cumulative inflation rate (1 years)

Plugging in the values to this equation, we get:

10.5 - 10.710.7

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 1876, our investment would be nominally worth approximately $0.85 in 1877. This is a return on investment of -15.07%, with an absolute return of $-0.15.

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 -1.90% of returns ($0.00) during this period. This means the inflation-adjusted real return of our $1 investment is $-0.15.

Investment in S&P 500 Index, 1876-1877
Original Amount Final Amount Change
Nominal $1 $0.85 -15.07%
Inflation Adjusted
$1 $-0.15 -15.35%
