It adds the metering charge. This is a fixed amount for each month.
It multiplies the kWh by the rate of the distribution system charge.
It multiplies the kWh by the rate of each of the 5 riders in the riders table, from the transmission cost recovery factor (TCRF) to the interim surcharge (Rider IS).
It multiplies the kWh by the rate of the mobile generation rider (December only).
It multiplies the kWh by the energy charge of your plan, and adds the monthly charge of your plan if you type one. These are the charges of your retail electric provider.

The calculator rounds each line to the cent. Each percentage uses the rounded lines.

Values read from the text of the Oncor Tariff for Retail Delivery Service, as linked from the Oncor tariffs and rate schedules page. Oncor is a delivery company: your retail electric provider bills these charges and adds the energy charge of your plan. The nuclear decommissioning charge is $0.000000 per kWh and is not shown. The interim surcharge (Rider IS) applies through December 2026. The mobile generation rider applies to December bills only. The TCRF, DCRF and EECRF history tables on the same sheets agree with the 2025 values in Oncor's earlier residential rate summary for retail providers. The PUCT residential delivery rate comparison page still shows September 2025 values, so it is not used as a check. The test bills are hand calculations. Oncor tariffs and rate schedules page.

Questions about Oncor bills

Why does Oncor not send me a bill?

Oncor delivers electricity in its area of Texas. Your retail electric provider sends the bill. The provider adds the Oncor delivery charges and the charges of your plan.

Where do I find the energy charge of my plan?

Look at the Electricity Facts Label (EFL) of your plan. It shows the energy charge in cents per kWh and any base charge. Type those values in the calculator.

Why is there a mobile generation charge in December?

The Oncor tariff applies the mobile generation rider in the December billing month only.

How often do the delivery charges change?

The TCRF changes about two times each year. The DCRF and EECRF change one or more times each year. The interim surcharge ends after December 2026. We check the values each month.

Why is my Oncor bill so high?

The most common reason is more kWh: heating and air conditioning use much electricity. Charges that change each month: mobile generation rider (December only). More days in the billing period also add kWh and daily charges.

Why is my bill different from the result?

Your bill can include sales tax, a city fee, a discount, a late fee or a different number of days. Type the number of days from your bill. To add tax, type the tax rate from your bill in the tax field. If your tariff has a discount program, select it in the options.

Where do I find my kWh?
