Our math
Will a lower rate mean a lower bill?
Your usage, fees and bill credits decide what you pay.
The short version
Why doesn’t a low rate tell the whole story?
The rate is just one piece of your bill.

Why isn’t my bill just the rate × usage?
Delivery, fees and tax add to the energy charge. A bill credit may reduce the total.
We compare costs using your home’s usage. A kilowatt-hour (kWh) measures how much power you use.
Will this plan fit my summer and winter bills?
We price each month at your usage, season by season.
Tell me more
We compare plans at the same monthly usage, including seasonal changes. Missing months are estimates. Free-night plans need readings that show when you use power.
Why is my bill higher than the quoted rate?
The quoted rate may assume a different usage or credit.
Tell me more
The rate may assume usage or a bill credit that does not fit your home. Delivery, fees and taxes also affect the total.
- Energy: the power you use.
- Delivery: getting power to your home.
- Fees and credits: extra charges or money off.
Could switching fees wipe out my savings?
Yes. Count exit fees and lost credits.
Tell me more
Yes. Leaving early can mean an exit fee or lost credits. Compare staying and switching over the same dates. Refundable deposits appear separately.
Could my rate go up later?
Variable rates can. Fixed rates stay set for the term.
Tell me more
Variable rates can change. Fixed rates last for the contract term, though allowed delivery and tax changes can still affect your bill.
Are you checking every plan?
No. We check a limited set of Texas plans.
Tell me more
Our results cover a limited selection of Texas plans. Other plans may cost less. Check the comparison date and confirm the offer with the provider.
Do past prices show what I would save today?
No. Past prices are context, not offers.
Tell me more
No. Past prices and state averages are context, not current offers. Use a current comparison before choosing.
How are past costs calculated?
We match prices to the same home and billing dates. If a rate changes mid-bill, we spread usage evenly across the days. The start day counts and the end day does not. Only periods with enough information enter both totals. The range uses the lowest and highest rates in each period. Assumed fees or missing readings can change the estimate. State averages use the invoice month, which can differ from the usage period. Published averages can change.
