OK residential rate
Oklahoma electricity cost calculator
This calculator uses Oklahoma's residential electricity price of 13.31 cents per kWh as the default. Replace it with your own utility rate for a bill-level estimate.
In the same EIA table, Oklahoma's residential rate was 13.31 cents per kWh for the prior-year month, which is about the same as the prior-year month.
How to use this state rate
A state average is a useful planning baseline for comparing appliances, but it can be different from the delivered rate on a household bill. Utility territory, time-of-use pricing, taxes, and fixed charges can change the final bill.
When this page is most useful
- Comparing whether an appliance is expensive to run in Oklahoma versus the national default.
- Estimating seasonal devices like space heaters, window air conditioners, and dehumidifiers.
- Building a first-pass budget before replacing the default with your own utility bill rate.
