Compare curated usage scenarios, then open a page to adjust watts, runtime, duty cycle, quantity, and ZIP code in the real calculator.
Open the full appliance calculatorThe comparison uses each appliance's reference scenario and the published Texas state-average residential rate. It is a consistent comparison, not a household tariff.
| Appliance | Scenario | Energy/month | Estimated/month |
|---|---|---|---|
| How Much Does It Cost to Run a Space Heater? | 6 hours a day on 20 days in a month | 144.00 kWh | $22.75 |
| Electric Dryer Cost per Load and per Month | 45-minute cycles, twelve times per month | 22.95 kWh | $3.63 |
| Refrigerator Electricity Cost per Month and Year | 150 watts with a 35% compressor duty cycle | 37.80 kWh | $5.97 |
| Dishwasher Electricity Cost per Cycle and Month | One-hour cycles, fifteen times per month | 8.10 kWh | $1.28 |

A space heater's cost depends mainly on rated watts, how many hours it runs, and how often its thermostat cycles the heating element. Use the preset calculator below with your ZIP code for a state-average estimate.
View scenarios and calculatorElectric dryer cost is driven by heater wattage, cycle length, and the number of loads. The scenarios below use the same calculation engine as the interactive appliance calculator.
View scenarios and calculatorA refrigerator is plugged in continuously, but its compressor cycles. Wattage and duty cycle therefore matter more than simply entering 24 full-power hours every day.
View scenarios and calculatorDishwasher electricity cost varies with cycle length, water-heating and drying behavior, and how often the machine runs. These scenarios isolate appliance electricity and do not include water or household water-heater fuel.
View scenarios and calculatorEvery scenario runs through the versioned HomeCost Radar appliance-energy engine. The engine converts watts and effective runtime to kilowatt-hours, applies the active state-average residential electricity publication, and returns a range with a confidence level.
