The True Cost of Running Major Appliances (Washer, Dryer, Dishwasher) in Texas
If you live in Texas, you know that keeping the air conditioning running from June through September is the biggest driver of your electricity bill. But what about the other heavy lifters in your home? Every time you run a load of laundry or start the dishwasher, you are adding to your monthly kilowatt-hour (kWh) usage.
Understanding the true cost of running major appliances—like your washer, dryer, and dishwasher—can help you make smarter choices about when and how you use them. Let's break down the math for Texas households and look at how these everyday chores impact your deregulated electricity bill.
How Much Power Do Your Appliances Actually Use?
To figure out what an appliance costs to run, you need two pieces of information: how many watts the appliance uses, and what you pay per kWh for electricity.
In the Texas deregulated market, your electricity rate includes both your energy charge and the TDU (Transmission and Distribution Utility) delivery charges from companies like Oncor, CenterPoint, or AEP. For these examples, let's assume a realistic, all-in Texas rate of 14 cents per kWh.
The Clothes Dryer: The Energy Hog
Your electric clothes dryer is likely the second most power-hungry appliance in your home, right behind the HVAC system.
- Average Usage: A typical electric dryer uses about 3,000 to 4,000 watts per hour.
- Cost per Load: Running a dryer for an hour at 14 cents per kWh costs about 42 to 56 cents.
- Monthly Impact: If your family does 5 loads of laundry a week (20 loads a month), the dryer alone is adding about $8.40 to $11.20 to your monthly bill.
The Washing Machine: The Hidden Water Heating Cost
The washing machine itself doesn't use a massive amount of electricity to spin the drum—usually only about 400 to 800 watts. The real cost comes from heating the water.
- Average Usage: If you wash in cold water, a load might only use 0.3 kWh (about 4 cents). If you wash in hot water, the electric water heater has to work hard, pushing the usage closer to 2.0 kWh per load.
- Cost per Load: Cold water wash: ~4 cents. Hot water wash: ~28 cents.
- Monthly Impact: At 20 loads a month, switching from hot to cold water can save you nearly $5 a month just on the washing machine's energy footprint.
The Dishwasher: Efficiency Matters
Modern dishwashers are incredibly efficient, especially compared to hand-washing dishes with hot water running constantly.
- Average Usage: A standard cycle uses about 1.2 to 1.5 kWh, mostly to heat the water and run the drying element.
- Cost per Load: At 14 cents per kWh, a load of dishes costs about 17 to 21 cents.
- Monthly Impact: Running the dishwasher every night (30 times a month) adds about $5.10 to $6.30 to your bill.
| Appliance | Est. Cost Per Load (at 14¢/kWh) | Est. Monthly Cost (Typical Family) |
|---|---|---|
| Electric Dryer | $0.42 - $0.56 | $8.40 - $11.20 (20 loads) |
| Washer (Hot Water) | $0.28 | $5.60 (20 loads) |
| Washer (Cold Water) | $0.04 | $0.80 (20 loads) |
| Dishwasher | $0.17 - $0.21 | $5.10 - $6.30 (30 loads) |
4 Steps to Lower Your Appliance Costs in Texas
You can't stop doing laundry or washing dishes, but you can change how you do them to lower your power bill.
- Wash clothes in cold water: As the math shows, the vast majority of a washing machine's energy goes toward heating the water. Modern detergents are formulated to work perfectly in cold water.
- Clean the dryer lint trap: A clogged lint filter forces your dryer to run longer to dry the same amount of clothes. Clean it before every single load.
- Turn off heated dry on the dishwasher: The heating element at the bottom of the dishwasher uses a significant amount of power. Turn off the "heated dry" setting and let your dishes air dry instead.
- Run full loads only: Your washer and dishwasher use roughly the same amount of electricity and water whether they are half full or stuffed to the brim. Wait until you have a full load to hit start.
Beware of "Free Nights and Weekends" Traps
Many Texans see the cost of running appliances and think a "Free Nights" or "Free Weekends" electricity plan is the perfect solution. The logic seems sound: just run the dishwasher and do all the laundry at night when power is "free."
Here is the catch: to make up for those free hours, the retail electricity provider usually charges a massively inflated rate during the day. If your daytime rate is 22 cents per kWh, the extra cost of running your AC during a 100-degree Texas afternoon will completely wipe out the few dollars you saved by doing laundry at 9:00 PM. For most households, a straightforward, low fixed-rate plan is much cheaper overall.
Pro Tip: If you are comparing plans on Power to Choose, remember that the advertised 500, 1000, and 2000 kWh prices are ALL-IN average prices based on PUCT rules. You do not need to add TDU base fees on top of those numbers.
How Powrly Helps
Figuring out the cost of running major appliances is helpful, but the biggest factor in your energy costs is the rate you pay per kWh. Powrly Analyzer looks at your actual, historical usage and projects it forward using seasonally-adjusted calculations. We know that your summer usage in Texas will be much higher than your spring usage, and our math reflects that reality. The paid report even includes a 12-month visual bar chart comparing your current plan's costs against our recommended plan, plus a cumulative savings line, so you can see exactly where your money is going.
The Bottom Line
Running major appliances like your washer, dryer, and dishwasher makes up a noticeable chunk of your monthly electricity bill. By switching to cold water washes, air-drying dishes, and keeping your lint trap clean, you can shave dollars off your bill every month. But the best way to save is to ensure you aren't overpaying for the electricity itself.

FAQ
Does unplugging appliances save money on my Texas electric bill?
Unplugging small electronics (like chargers or coffee makers) prevents "vampire draw," but it only saves a few dollars a year. You should not unplug major appliances like washers or dishwashers.
Is it cheaper to run appliances at night in Texas?
Only if you are on a specific Time-of-Use (TOU) or "Free Nights" plan. If you are on a standard fixed-rate plan, you pay the exact same amount per kWh regardless of what time it is.
Should I upgrade to ENERGY STAR appliances?
If your current appliance is broken or very old, upgrading to an ENERGY STAR model will save electricity and water. However, the energy savings alone usually aren't enough to justify replacing a perfectly good, working appliance.
