Appliance Wattage & Usage
Check source-backed appliance power and energy-use references. These values are representative starting points, not model specifications.
Representative appliance wattage
Published nameplate examples for common household devices. Use your own label or measurement whenever possible.
| Appliance or device | Low(W) | High(W) | Published context |
|---|---|---|---|
| Coffee maker | 900 | 1,200 | Operating range |
| Clothes washer | 350 | 500 | Operating range |
| Electric clothes dryer | 1,800 | 5,000 | Operating range |
| Dishwasher | 1,200 | 2,400 | Drying feature can materially increase use |
| Dehumidifier | 785 | 785 | Single published example |
| Portable electric heater | 750 | 1,500 | Operating range |
| Microwave oven | 750 | 1,100 | Nameplate input range |
| Ceiling fan | 65 | 175 | Operating range |
| Window fan | 55 | 250 | Operating range |
| Laptop computer | 50 | 50 | Single published example |
| RefrigeratorThe source advises estimating maximum-wattage runtime as roughly one-third of plugged-in time for this example. | 725 | 725 | Frost-free, 16 ft³; compressor cycles |
| Flat-screen television | 120 | 120 | Single published example |
| Toaster | 800 | 1,400 | Operating range |
| Vacuum cleaner | 1,000 | 1,440 | Operating range |
Use the most specific value available
For a real estimate, prefer the appliance nameplate, manufacturer documentation, an EnergyGuide or certification record, or a safe measurement. Rated maximum power can differ from average draw because compressors, heaters, motors, and controls cycle.
Enter the value you choose in the appliance running cost calculator. The calculator keeps runtime and electricity rate separate so a representative wattage never becomes a claim about your actual use.
