Electric Bill Calculator

Enter your usage and rate from your utility bill. We’ll show your estimated monthly total and how it shifts if your usage goes up or down.

Monthly usage (kWh) In kilowatt-hours. Find this on your bill labeled “energy used,” “kWh used,” or “total kWh.” US average is around 900 to 1,200 kWh/month.

Energy rate (cents/kWh) Your supply rate per kWh, from your bill or plan document. Texas fixed-rate plans typically run 8 to 16 cents/kWh.

Base or service charge ($/mo) A flat monthly fee charged regardless of usage. Look for “customer charge” or “service charge” on your bill. Enter 0 if none.

Delivery or wires charge (cents/kWh) In Texas, your wires company (Oncor, CenterPoint, AEP, TNMP) charges a separate per-kWh delivery fee. Deregulated states like PA, OH, IL, NY, and MA have similar separate charges. If your rate is all-in, enter 0 here.

Bill credit ($) Dollar amount credited when you hit the usage threshold.

Credit threshold (kWh) Minimum monthly usage to earn the credit.

What you actually paid last month ($) We’ll show how close this estimate is to your real bill.
