Electricity Bill Calculator
Advertised rates are priced at 2,000 kWh — a level most homes never hit. This calculator shows what you'll actually pay each month based on how much your home uses.
Enter your ZIP to load the full calculator with real plans and real costs.
Why the Advertised Rate Isn't Your Bill
Every Texas electricity plan comes with an Electricity Facts Label (EFL) that shows the rate at 500, 1,000, and 2,000 kWh. Providers advertise the 2,000 kWh number because spreading fixed charges over more kilowatt-hours makes the per-kWh rate look lower.
But most Texas homes use between 800 and 1,400 kWh per month. At those levels, base charges, minimum fees, and delivery costs take a bigger bite — and your real rate can be 20–40% higher than the advertised number.
What This Calculator Factors In
Energy Charge
The per-kWh rate your provider charges for the electricity itself.
Base & Minimum Charges
Fixed monthly fees that don't change regardless of how much your home uses.
TDU Delivery Fees
Your local utility charges for delivering power through the grid — these vary by TDU territory.
Credits & Discounts
Some plans include bill credits at certain levels — but only if you hit the exact threshold.
How the full calculator works
After you enter your ZIP code, we load every plan available at your address. Adjust the slider to match how much electricity your home typically uses, and we'll show your estimated monthly bill for each plan — not just the advertised rate.
Not sure how much your home uses? Check your last electricity bill — it shows your monthly kWh. Small apartment? 500–800 kWh. Average home? 1,000–1,200 kWh. Large home with pool? 1,500–2,500 kWh.
