Why the cost differs in South Carolina
South Carolina has the 25th cheapest residential electricity of the 51 US states and territories we track, at 16.18¢ per kWh against a national average of 18.44¢. That is -12.3% compared with the national figure. South Carolina has nuclear-heavy generation, and rates still reflect recovery of costs from the abandoned VC Summer reactor project, a construction failure households continue to pay for. Retail service is regulated. Long humid summers make cooling the dominant load, with widespread electric heating adding a real winter component.
For this appliance specifically, the difference works out to a saving of $21.03 a year against what the same electric clothes dryer would cost at the national average rate. Run the identical appliance in Hawaii and it would cost $484 a year; in Idaho it would cost $115. That spread of $369 is entirely down to location.
That is about 8.9% of a typical South Carolina household's annual electricity bill from this one appliance, which is enough to be worth optimising.
South Carolina sits below the national average, so this electric clothes dryer costs slightly less to run here than it would for a typical US household. How you use it will move the number far more than where you live.
Retail service in South Carolina is regulated, so most households pay a tariff set through state rate cases rather than a shopped rate. The state average is a reasonable proxy, though your utility's specific tariff still varies.

About running a electric clothes dryer
One of the most expensive loads in the home. Heat pump dryers use roughly half the energy of resistance models. Cleaning the lint filter and venting matters - restricted airflow extends cycle time and directly raises cost.
What actually changes the cost
- Models vary widely, from about 1800W to 5000W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.
How we worked this out
The arithmetic is simple and we would rather show it than hide it. Divide watts by 1,000 to get kilowatts, multiply by hours of use and by the duty cycle to get kilowatt-hours, then multiply by your rate:
3000W ÷ 1000 × 1h × 85% = 2.550 kWh/day × 16.18¢ = $0.413 per day
One honest caveat: South Carolina’s figure is a state average published by the EIA. Your own utility’s tariff, any time-of-use pricing, fixed monthly service charges and local taxes all shift the real number. Put your actual per-kWh rate into the calculator above for a figure that reflects your bill.
Questions about electric clothes dryer running costs
How many watts does a electric clothes dryer use?
A typical electric clothes dryer draws about 3000 watts while running, with most models falling between 1800W and 5000W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a electric clothes dryer use per day?
At around 1 hour of use a day and a 85% duty cycle, that works out to roughly 2.55 kWh per day, or about 77 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same electric clothes dryer, used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a electric clothes dryer at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
