Electricity Bill Calculator
Estimate your electricity bill using your energy usage, electricity rate, and utility charges.
Your electricity usage
Use figures for the same billing period.
Enter both readings from the same meter. The final reading must be at least as high as the initial reading.
Your utility charges
Enter your own rate; no national average is assumed.
Enter fixed charges and additional taxes or fees as dollar totals for the entire billing period, not daily charges or tax percentages. Do not add charges already included in your electricity rate.
Your estimated bill
This is an estimate based on the figures you provide. Your actual bill may differ because of utility-specific charges, tiered rates, demand charges, taxes, credits, or other adjustments.
How to use the calculator
Choose whether to enter total electricity use in kWh or two meter readings. Enter your electricity rate and the billing-period charges shown on your utility bill. The estimate updates automatically as you change the inputs.
Assumptions and limitations
The calculator applies one electricity rate to all kWh used and adds the fixed charges and additional fees you enter. It does not automatically account for tiered pricing, time-of-use rates, meter rollover, utility-specific adjustments, or charges already included in your rate.
