It estimates an electric bill from monthly kWh usage, electricity rate, delivery charges, fixed customer fees, taxes, and billing days.
kWh usage index

FAQ
Short answers for search visitors and bill-checking moments.
How do I estimate a bill from kWh?
Multiply monthly kWh by the energy rate, then add delivery charges, fixed customer fees, taxes, and other line items from the bill.
Why is the bill higher than kWh times the rate?
The advertised kWh rate often excludes delivery, fixed monthly charges, taxes, and public program fees.
Which kWh page should I choose?
Choose the page closest to the usage shown on your bill, then edit the usage and rate inside the calculator.
Why is my kWh cost different from the rate on my bill?
The listed energy rate may exclude delivery, customer charges, riders, taxes, or minimum fees. Use the calculator fields for those items to get the all-in cost.
