The published figure is a calculation, not a measurement
By RealCostTools. Sources checked September 20, 2026. For households in the United States. All amounts are U.S. dollars and electricity rates are in cents per kilowatt-hour.
There is no yellow EnergyGuide label on a clothes dryer to read an annual operating cost from: the Federal Trade Commission's list of products that carry one includes the clothes washer and not the dryer sold beside it. What exists instead is EPA's ENERGY STAR Product Finder, where every certified model publishes an estimated annual energy use in kilowatt-hours.
That estimate is arithmetic, and ENERGY STAR states the method on every model's page: the Combined Energy Factor carried over 283 cycles a year, referencing the Department of Energy test procedure. 283 cycles is 5.42 loads a week, every week, for every household alike.
It is also more laundry than most homes do: EIA's Residential Energy Consumption Survey puts 67.48 million of the 102.32 million U.S. homes with a dryer — 65.9% of them — in the band of one to four loads a week. So the published number is a fair starting point and a poor finish, and the work is replacing its load count with yours.

What to collect before you can answer this
Three of these you can look up. The fourth is a count nobody can do for you, and it is the one that decides the answer.
- Your electricity rate in cents per kilowatt-hour, taken from your own bill rather than a national average.
- Your dryer's make and model, so you can look it up on the ENERGY STAR Product Finder: if it is listed, take its estimated annual energy use and the test cycle time beside it.
- Whether the machine is vented or ventless, and whether it is full size or compact: that split matters far more than the brand.
- How many loads you actually dry in a normal week, counted rather than guessed.
How many watts a dryer uses, and where its kilowatt-hours come from
The Combined Energy Factor is not a consumption figure. ENERGY STAR defines it as the test load in pounds divided by the machine's electricity use across its operating and standby cycles, so the units are pounds per kilowatt-hour and higher is better. Three published figures turn it into kilowatt-hours.
Almost every certified full-size electric dryer sits on the same line. Of the 243 electric standard vented models EPA listed for the United States on September 20, 2026, 241 carry a Combined Energy Factor of 3.93 or 3.94 — the certification minimum, or one hundredth above it — and report 607 or 608 kilowatt-hours a year. The label separates certified dryers from uncertified ones; between certified full-size vented models it barely separates anything.
| Figure | Value | Where it comes from |
|---|---|---|
| Combined Energy Factor | 3.93 lbs/kWh | ENERGY STAR's minimum for a standard-size electric dryer. |
| Test load | 8.45 lbs | ENERGY STAR's standard load, dried in 80 minutes or less. |
| Cycles assumed in the annual figure | 283 a year | ENERGY STAR, referencing the DOE test procedure. Not a survey. |
| Estimated annual energy use | 608 kWh | Published per model, and reproduced by the rows above. |
| Energy per cycle | 2.1484 kWh | 608 ÷ 283, derived here. |
| Published test cycle time | 72 minutes | Middle of those 148 listings, which run 50 to 78 minutes. |
| Average power across the cycle | 1,790 W | 2.1484 kWh ÷ 1.2 hours, derived here. |
| Peak draw of the heating element | Not published | Not on the Product Finder, not on any label, and the DOE test procedure sits behind a bot check this site does not complete. |
The average-power row is what makes a watts-and-hours estimate possible for a dryer at all, and it is an average rather than a draw: 1,790 watts would use the same energy over 72 minutes, and is not a reading you would see at any instant. What the machine pulls moment to moment is the last row.
ENERGY STAR says plainly that the published cycle time "does not reflect actual consumer cycle times", which vary with load size, dampness and fabric. Two listings at the same 608 kilowatt-hours sit 28 minutes apart on it — the same energy, very different average power.

Worked example: 608 kWh, $111.51 a year, $0.3940 a load
Unusually for this site, nothing below is invented: the wattage, cycle length, load count and rate all come from the published figures above. That makes it no more yours. It describes the middle of a certification list — not a typical dryer, not a measurement, and not your laundry.
Enter 1,790 watts, 1.2 hours a cycle, and 5.42 operating days a week with one load each — ENERGY STAR's 283 cycles a year — at the U.S. residential average of 18.34¢ per kilowatt-hour. The second machine is the middle of EPA's 42 certified electric standard ventless listings, 266 kilowatt-hours a year: a published figure, not a percentage applied to the first.
Excluded: the price of either machine, installation, a vent or a drain, the washer, water, detergent, maintenance, repairs, and any difference in how long the machines last. These are one year's dollars repeated and undiscounted, added at their stated value without adjusting for the time value of money.
| Item | Amount |
|---|---|
| Electricity a cycle: 1,790 W × 1.2 hours | 2.1484 kWh |
| Electricity a year | 608.00 kWh |
| Electricity cost a year | $111.51 |
| Electricity cost a month | $9.29 |
| Electricity cost a load | $0.3940 |
| The ventless comparison: 266 kWh a year | $48.78 |
| Difference a year | $62.72, or 56.25% |
The annual row returns exactly the 608 kilowatt-hours EPA publishes: watts and hours reproduce the listed figure rather than approximate it. The calculator's weekly schedule counts 52.1775 weeks a year rather than 52, so 5.42 operating days is 283 cycles.
A year earlier the same kilowatt-hours cost $106.22, at EIA's June 2025 average of 17.47¢: neither the machine nor the load count moved, so the whole 5.0% is the rate.
Reference: ENERGY STAR: Clothes Dryers Key Product Criteria · ENERGY STAR: Product Finder, certified residential clothes dryers · EIA: Electric Power Monthly, Table 5.6.A
Loads a week moves the answer much further than the machine does
Each row below changes one input and holds everything else: the same dryer, the same 18.34¢, quantity one. The load counts are the edges of the bands EIA publishes, plus ENERGY STAR's own assumption, so the table is a set of scenarios rather than a description of anyone's week.
| Loads a week | Electricity a year | Cost a year | Cost a month |
|---|---|---|---|
| 1 | 112.10 kWh | $20.56 | $1.71 |
| 4 | 448.39 kWh | $82.24 | $6.85 |
| 5.42 — ENERGY STAR's assumption | 608.00 kWh | $111.51 | $9.29 |
| 9 | 1,008.89 kWh | $185.03 | $15.42 |
| 15 | 1,681.48 kWh | $308.38 | $25.70 |
From one load a week to fifteen, the bill moves by a factor of 15. Swapping the vented machine for the middle ventless listing moves it by a factor of 2.29. If you want the answer to change, the count is the lever; the machine is the smaller adjustment, and it costs money to pull.
The four-loads row tops the band EIA finds 65.9% of dryer-owning homes in, and lands $29.27 a year below the published figure. These rows entered the calculator as annual kilowatt-hours rather than watts and hours, because its weekly schedule stops at seven operating days. The ENERGY STAR row reproduces the worked example exactly, which is the check that the two entry modes agree.

What American households actually use, and why the range is so wide
EIA's Residential Energy Consumption Survey measures the other end of this: not what a certified machine uses on a test load, but what households report and EIA models from their bills. For 2020, the most recent year with consumption estimates published, it puts clothes drying at 680 kilowatt-hours a year per household using the end use — 11.8% above the 608 on the certified list.
Split by the number of people in the home, the same estimate runs from 391 kilowatt-hours to 1,231 — a factor of 3.15 across households drawing on one national stock of machines. The table above changed the load count deliberately; this is the same variable turning up in the field.
| Household | Electricity a year | Cost at 18.34¢ | EIA's relative standard error |
|---|---|---|---|
| 1 member | 391 kWh | $71.71 | 1.48% |
| 2 members | 620 kWh | $113.71 | 1.14% |
| 3 members | 809 kWh | $148.37 | 1.76% |
| 4 members | 943 kWh | $172.95 | 1.92% |
| 5 members | 1,060 kWh | $194.40 | 3.40% |
| 6 or more members | 1,231 kWh | $225.77 | 4.17% |
| All homes | 680 kWh | $124.71 | 0.78% |
The dollar column is arithmetic at one national rate, not EIA's: RECS publishes the kilowatt-hours, and each household paid its own price. The relative standard errors are EIA's own and are small, which says these estimates are precise — not that they describe your home.
Read this as an association, not a controlled comparison: larger households dry more laundry, but they also own different machines and different housing, and RECS holds none of that constant. The rows cover every dryer in use, not new certified ones, and EIA puts only 80.3% of dryer-owning homes on an electric machine — the gas and propane dryers still draw electricity for the drum and controls, pulling the average down.

Vented or ventless: what the machine is worth once the load count is settled
The certified list does separate machines, but by category more than by model: the whole span of full-size vented electric listings is narrower than the gap between that category and a ventless one.
| Product type | Models listed | kWh a year: lowest, middle, highest |
|---|---|---|
| Electric standard vented | 243 | 556 · 608 · 687 |
| Electric standard ventless | 42 | 208 · 266 · 608 |
| Electric compact ventless, 240 V | 45 | 122 · 283 · 317 |
| Electric compact ventless, 120 V | 9 | 133 · 133 · 133 |
The vent is doing most of the work there: a vented dryer heats air, passes it through the clothes and pushes it out of the building, while a ventless one condenses the moisture out and keeps the heat. Two compact vented categories list three models each and are too small to summarize.
Gas listings are left out on purpose. EPA publishes their annual figure in kilowatt-hours too, but states that it is multi-source equivalent energy rather than electricity, so it cannot be priced at an electricity rate. The first guide below handles that comparison in the units the two fuels are sold in.
None of this is a buying case. A ventless machine needs a drain or a tank to empty and costs more to buy, so the $62.72 a year above is one term in that decision rather than the decision. Setting it against a written quote is the second guide below.

What this figure does not tell you
It is not your dryer. EIA finds 82.8% of U.S. homes have one, and that most of those machines are not new — the largest age band is five to nine years — while the Product Finder lists only models certified and on sale now. An uncertified dryer uses more than 608 kilowatt-hours at the same load count, and by how much is published nowhere this guide could reach.
It is not the whole laundry either. Two ENERGY STAR points bear on the dryer's share: a certified washer gets significantly more water out of the clothes in its final spin, and what the washer leaves in is what the dryer drives off; and drying one towel for thirty minutes costs about as much as a full load over the same time.
And it is not a measurement. The one route to a number about your own machine is metering it: read your electricity meter before and after a counted set of loads, with as little else running as you can manage, and divide. Any meter has to match the supply — EPA's own listing splits electric dryers into 120-volt and 240-volt types — so follow its manufacturer's instructions or ask an electrician. Short of that, the published figure and your own load count are what the calculator prices.

Run your own dryer through it
Two routes in. If your model is on the Product Finder, take its published annual kilowatt-hours, scale them to your own loads — divide by 283, multiply by your count — and enter that as annual kilowatt-hours. If it is not listed, use watts and hours: your own cycle length, and an average power figure you can defend. The first table shows one way to reach that figure.
Then put your own rate in the cents-per-kilowatt-hour field, from your bill rather than a national average, and use the alternative-consumption field to set a second machine against the first. What comes out is one appliance's electricity — the part of this that can be calculated honestly.
