Watts to kWh
kWh = (W ÷ 1,000) × hours × load factor. Multiply kWh by your electricity price to estimate energy cost.
Compare similar loads with similar starting moisture. Replace example inputs with your own usage pattern.
2500 W × 2 h/day × 60 % load factor × 30 days.
This is an energy-only estimate. Your bill can also include standing charges, taxes and other household consumption.
Use the label, manual or manufacturer data for your exact model whenever possible.
| Type or situation | Indicative reference |
|---|---|
| Efficient heat pump | ≈0.8–1.5 kWh/cycle |
| Condenser dryer | ≈2–4 kWh/cycle |
| Vented / resistance | ≈2.5–5+ kWh/cycle |
Rated watts are only one part of the calculation.
kWh = (W ÷ 1,000) × hours × load factor. Multiply kWh by your electricity price to estimate energy cost.
Thermostats, compressors, inverter control and programmes can make real consumption lower or higher than a simple maximum-power estimate.
Quick answer
Tumble dryer wattage varies by model and technology, and the appliance does not necessarily draw its rated power for the full cycle. Use the nameplate input power for a rough estimate, but prefer measured kWh per cycle when available if you want a realistic running cost.
You can also compare it with washing machine electricity use.
Return to the appliance library or use the general electricity calculator for any device.
BRICODATO · PRACTICAL CHECK
Compare kWh for a completed drying cycle rather than rated maximum watts. Heat-pump and resistance dryers have different operating profiles, and results depend on spin speed, load size, fabric mix and filter maintenance. A longer cycle is not automatically a higher-energy cycle.
The figures elsewhere on this page are illustrative assumptions, not a measured average for every model. Use the label, your actual cycle count and safely collected kWh readings.
