Clothes dryer cost per load equals the electricity used during one complete drying cycle multiplied by your electricity rate. For an illustrative U.S. household paying USD 0.17/kWh, a cycle using 3 kWh costs USD 0.51; five loads per week would cost USD 132.60 per year. Your actual cost depends on the dryer, load moisture, cycle settings, and utility tariff—not simply the wattage printed on the appliance.
Clothes Dryer Cost Per Load: Inputs and Comparisons
The examples below show how energy use and electricity rates change the operating cost. Except for the identified EIA rate, all numerical inputs are hypothetical calculation assumptions, not typical consumption ratings or local utility prices.
| Calculation case | Energy per load | Electricity rate | Electricity cost per load | Applicable condition |
|---|---|---|---|---|
| Original hand-calculation example | 3.00 kWh | USD 0.17/kWh | USD 0.51 | Assumes 3,000 W average draw for one hour |
| Same load using a national reference rate | 3.00 kWh | USD 0.1831/kWh | About USD 0.55 | Uses the U.S. residential average for July 2026; not a local tariff. |
| Same load at a higher hypothetical rate | 3.00 kWh | USD 0.30/kWh | USD 0.90 | Illustrates rate sensitivity, not a particular location |
| Lower-energy cycle comparison | 1.00 kWh | USD 0.17/kWh | USD 0.17 | Valid only if the complete cycle actually uses 1.00 kWh |
Use complete-cycle kWh when available. Average power multiplied by elapsed time is an alternative, but rated or maximum power is not necessarily the average draw throughout a drying cycle. Appliance settings affect actual consumption.
These figures cover the dryer’s electricity consumption only. They exclude washing, detergent, purchase and installation costs, repairs, and any additional tariff-specific charges.
Calculate Electricity Cost Per Load
Formula and units
The appliance-energy calculation uses power, operating time, and the electricity price:
[
E_{\text{load}}=\frac{P_{\text{avg}}\times t}{1{,}000}
]
[
C_{\text{load}}=E_{\text{load}}\times r
]
Where:
- (E_{\text{load}}) = electricity consumed per complete drying cycle, in kWh.
- (P_{\text{avg}}) = average electrical power over that cycle, in watts.
- (t) = complete-cycle duration, in hours.
- (r) = applicable electricity rate, in USD/kWh.
- (C_{\text{load}}) = electricity cost per load, in USD.
Watts and kilowatts describe power; kilowatt-hours describe energy. A 3,000 W average draw is 3 kW, but it becomes 3 kWh only when sustained for one hour.
Worked example: 3,000 W for one hour
Assume an electric dryer averages 3,000 W across a 60-minute cycle and the household pays USD 0.17/kWh. These are example inputs, not a manufacturer rating or an official U.S. consumption benchmark.
Convert time:
[
60\text{ minutes}\div60=1.00\text{ hour}
]
Calculate electricity consumption:
[
E_{\text{load}}=\frac{3{,}000\text{ W}\times1.00\text{ h}}{1{,}000}
=3.00\text{ kWh}
]
Calculate cost:
[
C_{\text{load}}=3.00\text{ kWh}\times0.17\text{ USD/kWh}
=0.51\text{ USD}
]
The result is USD 0.51 for that assumed cycle. If 3,000 W is only the appliance’s rated input rather than its cycle-average draw, the calculation does not establish actual consumption.
A repeatable calculation process
- Identify the dryer type and model. Keep electric-resistance, heat-pump, and gas models separate when comparing energy costs.
- Find complete-cycle energy information. Prefer representative measured kWh or manufacturer data with stated test conditions. If using wattage and time, establish whether the wattage represents average or rated input.
- Convert units. Divide watts by 1,000 to obtain kilowatts, minutes by 60 to obtain hours, and cents/kWh by 100 to obtain USD/kWh.
- Check the applicable utility rate. Use the rate for your location, tariff, and drying period.
- Multiply energy by price. For time-of-use billing, calculate the portions consumed in each rate period separately.
- Record the load and settings. Compare similar laundry loads, starting moisture levels, and final dryness before judging which cycle costs less.
You can repeat the wattage-and-time calculation with the site’s appliance cost calculator, using the same assumptions.
Cycle Settings, Duration, and Energy Use
A setting name such as “high heat,” “delicates,” or “eco” does not establish a universal wattage or cycle duration. ENERGY STAR identifies moisture sensors, lower-temperature operation, and energy-saving cycles as ways dryers can reduce energy use, but the appropriate inputs remain model- and cycle-specific.
The following table illustrates combinations of average power and time. It is not a manufacturer settings chart, and none of the rows represents a typical dryer cycle.
| Hypothetical operating case | Average power across cycle | Complete-cycle duration | Calculated energy | Cost at USD 0.17/kWh |
|---|---|---|---|---|
| Shorter cycle | 3,000 W | 40 minutes | 2.00 kWh | USD 0.34 |
| One-hour cycle | 3,000 W | 60 minutes | 3.00 kWh | USD 0.51 |
| Longer cycle | 3,000 W | 80 minutes | 4.00 kWh | USD 0.68 |
| Lower-power, longer cycle | 1,500 W | 90 minutes | 2.25 kWh | About USD 0.38 |
The last row shows why runtime alone is insufficient: a longer cycle can use less electricity if its average draw is sufficiently lower. It does not prove that a particular low-heat setting will produce that result.
Load conditions also matter. ENERGY STAR advises leaving enough space for clothes to tumble and air to circulate; overloading can extend drying time. Very small loads are not necessarily economical either: its guidance notes that drying one towel for 30 minutes can cost about as much as drying a full load for the same time.
For useful comparisons, record both kWh per cycle and the amount of laundry dried. A low-cost partial load is not automatically more efficient than a somewhat higher-cost full load.
Choose the Electricity Rate That Matches Your Bill
As of October 12, 2026, the latest EIA Electric Power Monthly release covers July 2026 and was published on September 24, 2026. The U.S. residential average for that month was 18.31 cents/kWh, equivalent to USD 0.1831/kWh. This is a national reference starting point, not your local electricity rate or a full-year 2026 average.
EIA calculates average retail revenue per kWh from electricity sales revenues and volumes; it does not directly collect each customer’s tariff. That distinction matters when estimating the cost of one additional dryer cycle.
For your own calculation:
- Use the applicable usage-based electricity charges, including separately billed supply and delivery charges where relevant.
- Match time-of-use prices to when the dryer consumes electricity.
- Check whether additional consumption falls into a different pricing tier.
- Keep unavoidable fixed monthly charges separate when estimating the incremental cost of one load.
- If a facility’s tariff includes demand charges, assess them separately rather than treating the kWh calculation as the entire bill impact.
Dividing the whole bill by total kWh gives a blended bill average. It can help allocate household expenses, but it is not necessarily the marginal price of running one more load.
A common costing error is to multiply the dryer’s nameplate wattage by the entire cycle duration, then apply a national electricity average as though it were the household’s tariff. Both inputs need checking: actual power depends on operation and settings, while EIA’s national average is a revenue-based reference rather than a customer-specific rate.
Annual Cost at Five Loads Per Week
To reproduce the original example, assume:
- Energy per load: 3.00 kWh.
- Electricity rate: USD 0.17/kWh.
- Frequency: five loads per week.
- Annual period: 52 weeks.
- Consumption and electricity price remain constant throughout the year.
Annual loads:
[
N=5\times52=260\text{ loads/year}
]
Annual electricity use:
[
E_{\text{year}}=3.00\times260=780\text{ kWh/year}
]
Annual electricity cost:
[
C_{\text{year}}=780\times0.17=132.60\text{ USD/year}
]
The estimated annual electricity expense is USD 132.60 under these assumptions.
| Period | Loads | Electricity consumption | Electricity cost |
|---|---|---|---|
| One load | 1 | 3 kWh | USD 0.51 |
| One week | 5 | 15 kWh | USD 2.55 |
| Average month, calculated as annual total ÷ 12 | About 21.67 | 65 kWh | USD 11.05 |
| One year | 260 | 780 kWh | USD 132.60 |
The monthly figure is an annualized average, not a four-week month. Actual monthly costs change with laundry frequency, cycle energy, and seasonal or time-dependent rates.
For comparison, applying July 2026’s national residential reference rate to the same hypothetical annual consumption gives:
[
780\times0.1831=142.818\text{ USD}
]
That rounds to USD 142.82. It is a constant-rate illustration using one month’s national average, not a forecast of a household’s annual bill.
Electric-Resistance, Heat-Pump, and Gas Dryer Comparisons
ENERGY STAR’s current consumer guidance states that certified heat-pump dryers use around 70% less energy than conventional clothes dryers. Treat that as a broad technology comparison, not a guaranteed reduction for every model, setting, or household load.
| Dryer type | Operating-cost calculation | Comparison condition |
|---|---|---|
| Electric-resistance | Complete-cycle electricity in kWh × applicable USD/kWh | Compare similar laundry loads and final dryness |
| Heat-pump electric | Complete-cycle electricity in kWh × applicable USD/kWh | Use model-specific energy data rather than automatically applying a savings percentage |
| Gas | Gas consumed × applicable gas price, plus electricity consumed × applicable electricity price | Include both energy sources and use compatible gas units |
Heat-pump dryers reuse heated air in a closed-loop process and remove moisture through condensation. Their lower energy consumption is therefore a technology difference, not merely the result of selecting a cooler setting on a resistance dryer.
Illustrative heat-pump cost comparison
To demonstrate the arithmetic only, apply a 70% reduction to the hypothetical 3.00 kWh conventional cycle:
[
E_{\text{heat pump}}=3.00\times(1-0.70)=0.90\text{ kWh}
]
At the hypothetical USD 0.17/kWh rate:
[
C_{\text{heat pump}}=0.90\times0.17=0.153\text{ USD/load}
]
At 260 loads per year:
[
C_{\text{heat pump, year}}=0.90\times0.17\times260
=39.78\text{ USD/year}
]
The illustrative annual difference is:
[
132.60-39.78=92.82\text{ USD/year}
]
This demonstrates how ENERGY STAR’s broad savings statement would affect the example; it is not a certified energy rating for a particular dryer. Use the exact model’s data to estimate actual savings.
When comparing models, consult the ENERGY STAR Clothes Dryers Product Finder. ENERGY STAR uses Combined Energy Factor, or CEF, as an efficiency measure: higher CEF indicates greater efficiency. Compare equipment of suitable capacity and check the associated test conditions rather than treating the rating as a direct prediction of your household’s cost per load.
Reduce Cost Without Distorting the Comparison
Moisture-sensing cycles can stop drying when clothes are dry instead of continuing for a fixed time. ENERGY STAR also recommends choosing an energy-saving cycle, improving moisture removal in the washer, and cleaning the lint filter after every load to maintain airflow.
These actions address different parts of the calculation:
- Automatic termination can reduce unnecessary operating time.
- Better washer spin extraction reduces the moisture the dryer must remove.
- Appropriate loading supports tumbling and airflow.
- A clean lint filter helps maintain efficient airflow and is also an important safety measure.
For time-of-use customers, moving a cycle to a lower-priced period can reduce cost even if kWh consumption stays unchanged. ENERGY STAR identifies delayed start as a potentially useful feature where the utility offers time-of-use pricing. Check your own tariff before assuming nighttime drying is cheaper.
A valid comparison still requires equivalent results. Compare loads that reach the same usable dryness, and include any additional cycle needed to finish the laundry.
Dryer Cost Calculation Checklist
Use this checklist before relying on the estimate for household budgeting or equipment comparison:
- The calculation identifies an electric-resistance, heat-pump, or gas dryer.
- Energy covers the complete drying cycle, not just the heating portion.
- Wattage, when used, is clearly identified as average, rated, or assumed.
- Minutes are converted to hours and cents/kWh to USD/kWh.
- The electricity price matches the location and tariff.
- Time-of-use periods and any applicable tier changes are accounted for.
- Fixed charges are distinguished from the cost of an additional load.
- Compared loads have similar size, starting moisture, and final dryness.
- Annual totals use an explicit number of loads.
- Manufacturer test data and hypothetical inputs are labeled separately.
For national price context, use the EIA Electricity Monthly Update; for technology and efficiency guidance, use ENERGY STAR’s clothes dryer guidance. Your utility’s current tariff and the exact manufacturer’s documentation remain the relevant sources for local billing and model-specific operation.
These calculations estimate operating energy expense. They do not establish circuit capacity, NEC compliance, local AHJ approval, installation suitability, or guaranteed equipment performance; use the manufacturer’s instructions and applicable professional judgment for those decisions.
