How Inflation Calculation Works

Inflation calculation is based on the Consumer Price Index (CPI), which measures changes in the price level of a basket of goods and services purchased by households. The formula used is:

Adjusted Amount = Original Amount × (CPI in Current Year / CPI in Original Year)

For example, if you spent $100 in 1900 and the CPI in 1900 was 10 and the current CPI is 296.796 (as of 2023), the calculation would be:

Adjusted Amount = $100 × (296.796 / 10) = $2,967.96

This means $100 in 1900 would be equivalent to $2,967.96 today.

Historical Inflation Data

The inflation calculator uses historical CPI data from the Bureau of Labor Statistics (BLS) to provide accurate adjustments. The following table shows the CPI for selected years:

Year	CPI
1866	10.0
1900	10.0
1929	17.2

1965	33.5
1981	84.4
1997	172.2
2012	229.6

Note: The CPI for 1866 is based on the 1913=100 base year, which is the earliest available data from the BLS.

Common Mistakes to Avoid

When using an inflation calculator, it's important to avoid these common mistakes:

Using the wrong base year: Ensure you're using the correct base year for the CPI data.
Ignoring nominal vs. real values: Understand the difference between nominal amounts (not adjusted for inflation) and real amounts (adjusted for inflation).
Assuming linear inflation: Inflation is not linear and can vary significantly over time.
Not verifying the data source: Always check the source of the CPI data to ensure its accuracy.

For the most accurate results, use the latest CPI data available from the Bureau of Labor Statistics.
