Clothes Dryer Energy Cost Calculator
The clothes dryer is one of the hungriest appliances in the house — 1,800–5,000 W of heating element, cycle after cycle. Enter your loads per week and electricity rate to see what drying actually costs you.
Dryer type comparison (per load, at $0.16/kWh)
| Type | kWh/load | Cost/load | Year (5 loads/wk) |
|---|---|---|---|
| Vented electric | ~3.3 | $0.53 | $137 |
| Condenser electric | ~4.0 | $0.64 | $166 |
| Heat pump | ~1.5 | $0.24 | $62 |
kWh figures are typical mid-cycle energy use per standard load; real numbers vary with load size, spin speed and moisture.
What drives the number
- Your rate matters more than your dryer. The same vented dryer costs $0.40/load in Washington State and $1.45/load in Hawaii.
- Wet clothes in, energy out. A washer spin at 1,600 rpm can halve what the dryer has to evaporate versus 800 rpm.
- Blocked vents are silent money burners. A lint-clogged duct can double drying time and is also a fire risk — clean annually.
- Off-peak or solar drying. On time-of-use tariffs, drying at midday (solar) or off-peak can cut the rate you pay by 30–50%.
FAQ
How much electricity does a clothes dryer use per load?
A typical vented electric dryer uses 2.5–4 kWh per load; condenser dryers use about 4 kWh; heat pump dryers use only 1.2–1.8 kWh. At the U.S. average rate of $0.16/kWh, one load costs roughly $0.40–$0.65 in a vented electric dryer.
How much does it cost to run a dryer per month?
At 5 loads a week (about 20 per month) in a vented electric dryer, expect $8–$13 per month at average U.S. rates. In high-rate states like Hawaii or California the same usage can cost $22–$35 per month. A heat pump dryer cuts this by 50–60%.
Is a gas dryer cheaper to run than an electric dryer?
Usually slightly cheaper where natural gas is inexpensive — a gas dryer uses about 0.2–0.3 kWh of electricity plus 0.2–0.3 therms of gas per load, typically $0.30–$0.45 per load. But gas dryers cost more upfront and the gap has narrowed as gas prices rose; a heat pump electric dryer is now often the cheapest total-cost option.
How can I cut my drying costs?
The biggest lever is spin laundry faster in the washer (each extra 400 rpm removes meaningful water). Line-dry or rack-dry what you can, run full loads, clean the lint filter every load, and check the vent duct annually — a blocked vent can double drying time. If replacing the dryer, a heat pump model uses about 55% less energy per load.
