How much does a kWh cost?
In order to know how much it costs to run an electric appliance in your home, it is helpful to know your cost per kWh. Buying electricity is sometimes like buying sugar. A one-pound box of sugar is relatively expensive compared to the cost per pound of a 50 pound bag. Like sugar, electricity may be offered at a lower rate as you buy more. The amount of electricity you use in a billing period goes through rate steps and each step will have a different cost per kWh. Historically, residential electric rates have offered lower prices as you use more electricity in a billing period. However, it is not unusual for some rates to change in the summer months and charge more per kWh as you increase usage. This practice reflects the high demand for electricity during the air conditioning season. There are other rate adjustments that change frequently and therefore your cost per kWh will usually vary from one month to another. But it is easy to calculate your cost per kWh each month so you know ho
