How we calculate electricity cost

Your electricity bill is simply the number of kilowatt hours consumed multiplied by your utility's rate per kWh. This calculator applies your rate across daily, monthly, and annual timeframes.

Cost = kWh × Rate ($/kWh)

Use the blended rate from your bill — total electricity charges divided by total kWh used — for the most accurate result.
