Texas Electricity Bill Calculator
Electricity prices in Texas can vary widely by provider, plan type, location, and monthly usage. A household using 1,000 kWh may receive a very different bill from another home using the same amount of electricity. The reason is that Texas electricity plans often combine an energy rate, base charge, transmission and distribution utility (TDU) charges, and other fees.
A Texas Electricity Bill Calculator makes this comparison easier by estimating the monthly cost from your electricity usage and the rate you are considering. It can also help you compare electricity providers before signing a new contract.
The quick comparison below gives an example of how monthly electricity costs can change at different energy rates.

How to Use This Calculator
- Enter your monthly usage in kWh. This is on every bill and in your smart meter app. If you’re comparing plans before moving, estimate using a similar-sized home’s average.
- Select your TDU from the dropdown. This fills in typical delivery charges for your area — you can adjust either field if your utility’s current tariff differs.
- Enter your REP’s energy rate in cents per kWh, taken from the “Energy Charge” line of your Electricity Facts Label — not the blended average rate.
- Add any monthly base fee your provider charges regardless of usage. Many fixed-rate plans have none; some minimum-usage or no-deposit plans do.
- Enter a bill credit if your plan advertises one, along with the usage level it kicks in at. Set both to 0 if your plan has no credit structure.
- Add sales tax only if your actual bill shows a tax line — most residential accounts are exempt.
- Press Calculate to see your full estimated bill, a category-by-category breakdown, and your true effective rate per kWh.
Texas TDU Delivery Charges — Quick Reference
Approximate, regulator-filed rates used as calculator defaults. These update each March 1 and September 1, and occasionally outside that cycle after a rate case — always confirm against your TDU’s current tariff.
| TDU | Service Area | Fixed Charge | Per-kWh Rate |
|---|---|---|---|
| Oncor | Dallas / Fort Worth, North Texas | $4.23/mo | 4.58¢/kWh |
| CenterPoint Energy | Houston metro | $4.99/mo | 4.99¢/kWh |
| AEP Texas Central | South Texas | $3.24/mo | 5.83¢/kWh |
| AEP Texas North | West Texas | $3.24/mo | 5.67¢/kWh |
| TNMP | Scattered service territories | $7.85/mo | 7.24¢/kWh |
Understanding Your Texas Electricity Bill
Two companies, one bill
In deregulated Texas markets, your monthly bill actually combines charges from two separate companies. Your retail electric provider sells you the energy itself and sets its own competitive rate. Your TDU — the regulated utility that owns the poles, wires, and meter in your area — charges a separate, government-approved delivery fee that stays the same no matter which provider you choose.
Why your “average rate” isn’t the whole story
Advertised plan rates are usually shown as a blended average at a specific usage level, often 500, 1,000, or 2,000 kWh. Because delivery charges include a flat fixed fee, that blended rate looks different at every usage level — which is why a plan that looks cheap at 1,000 kWh can look expensive at 300 kWh, and vice versa. Entering your actual usage here gives you a truer picture than any single advertised number.
Bill credits change the math
Some plans offer a set dollar credit once you cross a usage threshold, then remove it entirely if you fall short. That structure can make a plan a great deal in one month and a poor one the next, depending on how much electricity you actually use. Modeling your real usage against the credit threshold, rather than trusting the headline rate, is the most reliable way to judge these plans.
What you can and can’t shop for
You can shop and switch your retail provider at any time. You cannot switch your TDU — it’s determined entirely by your street address and stays fixed even if you change providers. Any quote you compare should already reflect the correct delivery charges for your specific area.
Texas Electricity Cost Comparison
| Energy Rate | 500 kWh | 1,000 kWh | 2,000 kWh | Approx. Cost at 1,000 kWh |
|---|---|---|---|---|
| 10¢/kWh | $50 | $100 | $200 | $100 |
| 12¢/kWh | $60 | $120 | $240 | $120 |
| 14¢/kWh | $70 | $140 | $280 | $140 |
| 16¢/kWh | $80 | $160 | $320 | $160 |
| 18¢/kWh | $90 | $180 | $360 | $180 |
| 20¢/kWh | $100 | $200 | $400 | $200 |
These figures show the energy charge only. Actual Texas electricity bills can be higher because many plans include monthly base charges and TDU delivery charges. Use the comparison as a starting point, then check the Electricity Facts Label (EFL) for the exact plan.
If you also compare electricity costs in other parts of the country, our electric bill calculator by state can help you estimate residential electricity costs using state-specific rates and usage.
How a Texas Electricity Bill Calculator Works
A Texas Electricity Bill Calculator uses your monthly electricity consumption and the pricing structure of your electricity plan to estimate your bill.
The basic calculation is:
Monthly energy cost = Electricity usage × Energy rate
For example, if your home consumes 1,200 kWh and your effective energy rate is 14 cents per kWh:
1,200 × $0.14 = $168
However, this is not always the final amount shown on your bill.
A Texas electricity plan may include:
- Energy charges
- Monthly recurring charges
- TDU delivery charges
- TDU usage charges
- Regulatory fees
- Taxes
- Minimum usage fees
- Bill credits or discounts
- Renewable energy adjustments
This is why comparing the advertised electricity rate alone can lead to an inaccurate estimate.
What Are Electricity Rates in Texas?
Texas has a deregulated electricity market covering much of the state. In these areas, consumers can generally choose their retail electricity provider (REP), while the local transmission and distribution utility remains responsible for delivering electricity through the power grid.
Actual retail rates change frequently. In 2026, residential offers in competitive Texas markets can commonly fall in the broad range of roughly 10 to 20+ cents per kWh depending on the ZIP code, usage level, contract term, plan type, and market conditions.
For example, a plan advertised at 12¢ per kWh does not necessarily mean the customer will pay exactly $120 for 1,000 kWh. Delivery charges and other plan costs can increase the effective price.
The following example illustrates the difference.
| Monthly Usage | Advertised Energy Rate | Energy Charge | Other Charges* | Estimated Total |
|---|---|---|---|---|
| 500 kWh | 14¢ | $70 | $45 | $115 |
| 1,000 kWh | 14¢ | $140 | $60 | $200 |
| 2,000 kWh | 14¢ | $280 | $90 | $370 |
*Illustrative charges only. Actual TDU fees, provider fees, taxes, and credits depend on the electricity plan and service area.
For an exact quote, always check the provider's current EFL rather than relying on a general statewide average.
Texas TDU Delivery Charges Matter
One of the most important differences between Texas electricity pricing and a simple kWh calculation is the TDU delivery charge.
Depending on your location, your electricity may be delivered by companies such as:
- Oncor Electric Delivery
- CenterPoint Energy
- AEP Texas North
- AEP Texas Central
- Texas-New Mexico Power (TNMP)
The retail electricity provider sells the electricity plan, but the TDU maintains the poles, wires, meters, and local distribution network.
TDU charges normally include a monthly customer charge plus a per-kWh delivery charge. These charges can change when regulators approve new rates.
For this reason, two customers with the same electricity provider may have different total bills if they live in different TDU service territories.
Compare Texas Electricity Providers by Effective Cost
When comparing providers, focus on the estimated total bill rather than only the advertised rate.
Suppose three plans have the following advertised prices:
| Plan | Advertised Rate | Monthly Fee | Usage | Basic Energy Cost |
|---|---|---|---|---|
| Plan A | 12¢/kWh | $0 | 1,000 kWh | $120 |
| Plan B | 13¢/kWh | $9.95 | 1,000 kWh | $139.95 |
| Plan C | 14¢/kWh | $0 | 1,000 kWh | $140 |
At first glance, Plan A appears cheapest. But if Plan A provides a bill credit only at certain usage levels, its effective price may change considerably at 500 or 2,000 kWh.
This is why the EFL is one of the most useful documents when shopping for electricity.
How to Estimate Your Texas Electric Bill
You can estimate your bill in a few simple steps.
1. Find your monthly usage
Look at your previous electricity bills and identify your average kWh consumption.
A typical home might use:
- 500 kWh during a mild month
- 1,000 kWh during moderate weather
- 1,500 kWh or more during hot summer months
- 2,000+ kWh in larger homes with heavy air-conditioning use
Texas summers can have a major effect on electricity consumption because air conditioners may run for long periods.
2. Check the plan's electricity rate
Find the energy charge in the provider's EFL. Do not rely solely on the headline price displayed on a comparison website.
3. Add recurring charges
Check for monthly service fees, minimum usage charges, and other recurring costs.
4. Add TDU charges
Your delivery charges depend on your location and local utility.
5. Apply credits carefully
Some Texas electricity plans provide bill credits when consumption falls within a specific range. Missing that range can make the plan much more expensive.
Example: 1,500 kWh Texas Electricity Bill
Consider a household using 1,500 kWh in a month with an effective energy rate of 14¢ per kWh.
Energy charge:
1,500 × $0.14 = $210
If the plan has a $10 monthly charge and approximately $75 in delivery and other charges, the estimated bill would be:
$210 + $10 + $75 = $295
The actual bill could be higher or lower depending on the customer's TDU, taxes, provider charges, and any applicable credits.
A calculator is especially useful when you enter several usage levels. Testing 500, 1,000, 1,500, and 2,000 kWh can reveal whether a plan remains competitive as your consumption changes.
Fixed-Rate vs Variable-Rate Electricity Plans
Texas consumers can encounter several types of electricity plans.
Fixed-rate plans
A fixed-rate plan generally locks the energy rate for the contract period. This can make monthly budgeting easier.
However, fixed-rate does not mean the entire electricity bill is guaranteed to remain unchanged. TDU charges and certain government or regulatory costs may still change.
Variable-rate plans
Variable-rate plans can change according to market conditions and the provider's pricing terms. They may provide flexibility but can expose customers to higher rates.
Time-of-use plans
Some plans offer different prices during different periods of the day. These can benefit households that shift electricity consumption to lower-cost periods.
Prepaid plans
Prepaid electricity plans require customers to maintain an account balance and may have different fee structures from traditional postpaid plans.
What Makes a Texas Electricity Plan Expensive?
The advertised kWh rate is only one part of the equation.
Watch for:
- High monthly base charges
- Minimum usage fees
- Expensive rates below or above usage thresholds
- Short-term promotional pricing
- Early termination fees
- High variable rates
- Complicated bill-credit structures
- Large differences between advertised and effective prices
A plan offering 9¢ per kWh may not necessarily be cheaper than a plan offering 13¢ per kWh if the lower-priced plan has restrictive usage requirements.
How to Choose the Cheapest Texas Electricity Provider
There is no single cheapest provider for every Texas household. The best plan depends on your ZIP code and electricity consumption.
Before switching, compare:
- Electricity rate
- Estimated monthly bill
- Contract length
- Monthly base charge
- TDU delivery charges
- Bill-credit conditions
- Early termination fee
- Renewable energy content
- Deposit requirements
- Customer service and provider reputation
Your actual annual consumption is particularly important. A plan that looks attractive at 1,000 kWh may become expensive at 500 kWh or 2,000 kWh.

Texas Electricity Bill Calculator Formula
For a basic estimate, use:
Estimated bill = (kWh × electricity rate) + monthly fees + TDU charges + taxes − applicable credits
For example:
1,200 kWh × $0.15 = $180
If the plan adds $10 in monthly charges and $65 in delivery and other charges:
$180 + $10 + $65 = $255
The estimated monthly electricity bill would therefore be about $255 before any additional taxes, credits, or adjustments.
Tips to Lower Your Texas Electricity Bill
Reducing electricity consumption can be just as important as switching providers.
Try these measures:
- Set the thermostat efficiently during summer.
- Replace old bulbs with LEDs.
- Clean or replace HVAC filters regularly.
- Seal air leaks around doors and windows.
- Use smart thermostats to control cooling schedules.
- Wash clothes with cold water when practical.
- Run dishwashers and appliances during lower-cost periods when your plan supports time-of-use pricing.
- Compare electricity plans before your contract expires.
- Check your bill each month for unexpected fees.
Homes with older air-conditioning systems can often see significant savings from HVAC maintenance because cooling can represent a large portion of summer electricity consumption.
Frequently Asked Questions

How much is electricity per kWh in Texas?
Texas residential electricity rates vary by provider, ZIP code, plan, contract term, and usage. In 2026, residential offers can range broadly from around 10¢ to more than 20¢ per kWh. The effective price can be higher after delivery charges and other fees.
How much is 1,000 kWh of electricity in Texas?
At 12¢ per kWh, 1,000 kWh costs $120 before additional charges. At 15¢, the energy portion is $150, while at 18¢ it is $180. The final bill will depend on the provider's fees, TDU charges, taxes, and credits.
Which Texas electricity provider has the lowest rate?
There is no provider that is always the cheapest for every customer. Electricity prices vary by ZIP code, TDU territory, usage level, contract length, and plan conditions. Compare the estimated total bill and EFL rather than just the advertised kWh rate.
Why is my Texas electricity bill higher than my kWh calculation?
Your simple kWh calculation usually covers only the energy charge. Your final bill can also include TDU delivery charges, monthly fees, taxes, regulatory charges, and other costs. Bill credits may also depend on meeting specific usage thresholds.
Final Thoughts
Choosing an electricity plan in Texas requires more than finding the lowest advertised kWh rate. Your usage pattern, location, TDU service area, contract terms, monthly fees, and bill credits can all affect the final cost.
