Electricity in the CPI
Electricity is one of the pricing items collected by the BLS and monitored for inflation as a part of the Consumer Price Index (CPI). Electricity rates are more stable than prices for companion items like gasoline and fuel oil, but it still falls under the BLS’s main "Energy index." Therefore, although electricity costs are used along with many other goods and services in measuring overall inflation, keep in mind that they are completely discounted in calculating core inflation rates.
How are electricity prices affected by inflation? Less so than many other goods and services purchased by American consumers. As an example, the cost of electricity climbed from an average of 8.1 cents per kilowatt hour in 1985 to 13.5 cents in 2020, marking a 66.7% rate of increase in 35 years. That’s a sizable gain but, interestingly, plugging 8.1 cents and the two years into this site’s Inflation Calculator finds that electricity prices during the time increased slower than the rate of overall inflation. The often-reported overall inflation rate is calculated from measuring pricing changes over thousands of items — not just electricity rates. Overall inflation places 8.1 cents in 1985 at 19 cents in 2020 for a 140.5% rate increase.
How to Adjust Electricity Prices for Inflation
In calculating electricity prices for inflation adjustment, we’ll use an example that shows how to adjust them from 1979 to 2022. First, consider these facts which are shown in the table above:
- The average price for Electricity in 1979 was $0.050 per kilowatt hour.
- The annual average CPI for Electricity in 1979 was 65.600.
- The annual average CPI for Electricity in 2022 was 253.127.
The following formula shows how to adjust gasoline for inflation:
1979 Electricity Price x (2022 CPI for Electricity / 1979 CPI for Electricity) = Adjusted Electricity Price in 2022 Dollars
Using the actual numbers:
$0.050 x (253.127/65.600) = 19.3 cents per kWh
