Running an electric dryer for one hour typically costs about $0.30-$0.75, with a midpoint near $0.50; a gas dryer commonly costs $0.25-$0.55 including fuel and electricity. The actual price depends on energy rates, dryer type, heat setting, load size, and how often the heating element or burner runs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Electric dryer, 1 hour | $0.30 | $0.50 | $0.75 | About 2-5 kWh at $0.15 per kWh |
| Gas dryer, 1 hour | $0.25 | $0.38 | $0.55 | Gas plus electricity for motor and controls |
| Electric dryer, 1 year | $55 | $110 | $274 | 1-2 loads weekly, 1 hour each |
| Gas dryer, 1 year | $43 | $83 | $200 | Same use pattern; local fuel rates vary |
What one hour of electric dryer use usually costs
Most standard electric dryers use approximately 2-5 kilowatt-hours (kWh) during a one-hour cycle. At a residential electricity rate of $0.15 per kWh, that works out to about $0.30-$0.75, with roughly $0.50 a useful estimate for an ordinary load. A high-heat cycle, large wet load, or older machine can use more than a sensor-controlled cycle with a moderate load.
For a quick estimate, multiply the dryer’s hourly energy use by the electricity price on the utility bill. A 3.3-kilowatt dryer drawing power for an equivalent 45 minutes uses about 2.5 kWh, costing about $0.38 at $0.15 per kWh. Nameplate wattage is a maximum rating, not necessarily the amount drawn continuously: heating elements cycle on and off during many loads.
Assumptions: U.S. household electricity at $0.15 per kWh, normal venting, and a typical residential load.
How electricity, gas, and operating time shape the bill
The bill calculation combines energy use and the rate charged for it. Electric dryers use electricity for heat, the motor, and controls. Gas dryers burn natural gas or propane for heat but still use electricity to turn the drum and operate controls. The utility’s variable energy charge is the relevant rate for estimating an additional load; fixed monthly service charges generally do not change because of one dryer cycle.
| Cost component | Electric dryer | Gas dryer | What changes the amount |
|---|---|---|---|
| Heat or fuel | $0.28-$0.70 per hour | $0.18-$0.45 per hour | Heat cycling, fuel price, load moisture |
| Motor and controls | $0.02-$0.08 per hour | $0.03-$0.10 per hour | Run time and appliance efficiency |
| Typical total | $0.30-$0.75 per hour | $0.25-$0.55 per hour | Rates and actual cycle length |
For gas models, add gas charges and electrical use rather than treating the dryer as cost-free on electricity. Gas consumption is often around 0.15-0.30 therm per hour of active operation, but burner cycling means actual use varies. At $1.50 per therm, that gas portion is about $0.23-$0.45; motor and control power can add a few cents.
Why load size and heat settings change the hourly price
One hour is not a fixed amount of energy. A small, lightly damp load may finish early, while a bulky load or laundry spun at low speed may need most of an hour or an additional cycle. High heat can increase energy use compared with lower-heat settings, though cycle duration and moisture level are also important.
Dryers commonly draw about 3-6 kilowatts while an electric heating element is on, but it does not necessarily stay on for the full hour. At $0.15 per kWh, each additional kWh costs $0.15. If a load needs 30 extra minutes and uses an average 2 kW during that time, it adds about 1 kWh, or $0.15.
Wetness and airflow can matter as much as the selected temperature. A clogged lint screen, obstructed vent, or long vent run can extend drying time. Loads still damp after a normal cycle may indicate a maintenance or venting problem, not simply a need to use more heat.
Regional electricity rates can double the hourly estimate
At $0.10 per kWh, a 2-5 kWh electric cycle costs about $0.20-$0.50. At $0.15, it costs $0.30-$0.75; at $0.30, it reaches $0.60-$1.50. These examples show why a single national price can mislead. Rates vary by state, utility, season, and plan, and some time-of-use plans charge more during peak evening hours.
In a higher-priced market, the same appliance and load can cost 50%-100% more than in an area with a lower electricity rate. Gas prices vary as well; propane users should check their delivered fuel price because it may not match a natural-gas utility rate. Using the actual per-kWh and per-therm charges on a bill gives a more useful estimate than a national average.
Gas and electric dryers do not always have the same total price
Gas dryers often cost less to operate where natural gas is inexpensive, but the difference is not guaranteed. At typical example rates, an electric cycle may cost $0.30-$0.75 and a gas cycle $0.25-$0.55. In a home with costly gas or inexpensive electricity, the gas model may offer little or no operating-cost advantage.
Purchase and installation costs are separate from the hourly bill. A gas hookup, compatible vent, or required electrical work can affect the cost of switching dryer types. For an existing appliance, compare operating cost using the rates available at that home rather than relying only on the appliance label or fuel category.
Three household examples for a one-hour cycle
| Example | Calculation | Estimated cost |
|---|---|---|
| Small electric load | 2 kWh × $0.12 per kWh | $0.24 |
| Typical electric load | 3.3 kWh × $0.15 per kWh | $0.50 |
| Gas load | 0.22 therm × $1.50 plus $0.05 electricity | $0.38 |
These examples estimate energy charges only, not appliance purchase, repairs, or fixed utility fees. The electric examples assume the listed kWh reflects energy used during the cycle, rather than multiplying rated wattage by a full hour.
Small changes that lower the price of each load
Use the washer’s fastest appropriate spin setting to remove more water before drying, clean the lint screen, and check that the outside vent flap opens freely. Avoid overdrying by selecting a moisture-sensing cycle when it works well for the fabric. Combining compatible items into a full, not packed, load can reduce the number of cycles.
Drying during off-peak hours may help on a time-of-use electricity plan, but it does not lower the bill under a flat rate. Air-drying some items can avoid dryer energy altogether. Reducing unnecessary minutes is usually the clearest way to trim the operating cost without changing appliances.
Monthly and yearly dryer costs at common laundry rates
At $0.50 per electric load, running the dryer three times weekly costs about $6.50 per month or $78 per year. At $0.38 per gas load, the same schedule is roughly $4.95 monthly or $59 yearly. These estimates use 52 weeks per year and one hour per load; extra cycles, larger loads, and higher utility rates raise the totals.
For a personalized estimate, multiply the estimated kWh per load by the bill’s electricity rate, then multiply by loads per week and 52. For gas, calculate therm use at the billed rate and add electricity for the motor and controls. A plug-in energy monitor is generally unsuitable for a standard 240-volt electric dryer; the appliance label, utility data, or a qualified electrician’s measurement may help refine its consumption estimate.
