Clothes Dryer Energy Cost Calculator
A standard 3,000-watt vented electric dryer uses 2.25 kWh on a 45-minute cycle — $0.36 a load at the 2024 US average of $0.16/kWh, or $94 a year at 5 loads a week. A heat pump dryer does the same load for $0.19 and a gas dryer for about $0.29. The calculator opens on a large-capacity 5,000W dryer running 1 hour a day — change the wattage, the hours and your state below.

5,000 W ÷ 1,000 × 1 hour a day = 5.00kWh × $0.16 = $0.80 a day, or $0.80 for every hour the dryer runs. That is about 9.3 loads a week at a 45-minute cycle. The average US household does 5 — set hours per day to 0.54 for that.
Wattage is what the heating element draws while it is on, which on a dryer is most of the cycle — there is no thermostat holding a temperature the way an oven or an iron has. A gas dryer is the exception: it draws about 350 W for the drum and blower and buys its heat by the therm instead, so use the gas row in the table below rather than this calculator.

The Formula
Cost per load = (watts ÷ 1,000) × cycle hours × price per kWh
Dividing watts by 1,000 converts to kilowatts. Multiplying by the cycle length in hours gives kilowatt-hours (kWh) — the unit your utility bills you in. Multiply by your price per kWh and you have the cost of one load.
Worked example (3,000W dryer, 45-minute cycle, $0.16/kWh): (3,000 ÷ 1,000) × 0.75 × 0.16 = 3 kW × 0.75 hours × $0.16 = $0.36 per load.
Gas vs. Electric Dryer: Cost per Load and per Year
The same 10-pound load, dried five ways, at $0.16/kWh and $1.50/therm. Read the cycle column against the watts column before reading anything else: the machines that draw less run longer, which is why the heat pump saves about half rather than the two-thirds its nameplate suggests — and why the large-capacity dryer saves nothing at all. It finishes sooner; it does not finish cheaper.
| Dryer type | Watts | Cycle | kWh per load | Gas per load | Cost per load | Per year, 3 loads/wk | Per year, 7 loads/wk |
|---|---|---|---|---|---|---|---|
| Heat pump electricVentless, recycles its own heat. Longest cycle, cheapest load. | 1,000 | 70 min | 1.17 | — | $0.19 | $29 | $68 |
| Compact 120 V condenserApartment ventless. Resistance heat on a wall outlet, so it runs a long time. | 1,800 | 95 min | 2.85 | — | $0.46 | $71 | $166 |
| Standard vented electric (baseline)The 240 V machine in most American laundry rooms. | 3,000 | 45 min | 2.25 | — | $0.36 | $56 | $131 |
| Large-capacity vented electricBigger drum and more air to heat, but it finishes in half the time. | 5,000 | 30 min | 2.50 | — | $0.40 | $62 | $146 |
| Vented gasMotor and controls on electricity, heat from a burner. | 350 | 45 min | 0.26 | 0.17 therms | $0.29 | $45 | $105 |
The gas row is 350W of motor, blower and controls plus a 22,000 BTU/hr burner, which works out at 0.17 therms a load. At these two prices gas costs about 20% less per load than a standard vented electric — but that gap is set by your utility, not your machine. Gas and electric break even at around $0.12/kWh, so below that electricity is the cheaper heat.
Annual Cost at Five Electricity Rates
Annual electricity cost for a standard 3,000W vented dryer (2.25 kWh a load), across the rates most US households pay and the laundry habits behind them. Find your rate on your bill, then read across to your loads a week.
| Rate ($/kWh) | 3 loads/wk | 5 loads/wk | 7 loads/wk | 10 loads/wk |
|---|---|---|---|---|
| $0.10 | $35 | $59 | $82 | $117 |
| $0.13 | $46 | $76 | $106 | $152 |
| $0.16 (US avg) | $56 | $94 | $131 | $187 |
| $0.20 | $70 | $117 | $164 | $234 |
| $0.25 | $88 | $146 | $205 | $293 |
The kilowatt-hours behind these dollars never change: 7 loads a week is 819 kWh a year whatever your utility charges for them, and the whole spread from $0.10 to $0.25 is your zip code, not your laundry. A heat pump dryer costs about 52% of every dollar figure above. A gas dryer barely moves with the electricity rate at all, because almost all of its cost is the therm price.
Cost by Loads per Week
The same standard dryer at the US average rate, broken out by week and month for people who budget that way. The average US household does about 5 loads a week.
| Loads per week | kWh per week | Cost per week | Cost per month | Cost per year |
|---|---|---|---|---|
| 3 | 6.75 | $1.08 | $4.68 | $56 |
| 5 (typical household) | 11.25 | $1.80 | $7.80 | $94 |
| 7 | 15.75 | $2.52 | $10.92 | $131 |
| 10 | 22.50 | $3.60 | $15.60 | $187 |
How a Dryer Compares to the Rest of the Laundry Room
Drying is the expensive half of doing laundry, and it is worth knowing by how much. All three figures below are for the same load, using the models on each of those pages.
The washer costs a fraction of the dryer
A warm wash uses about 1.7 kWh, most of it heating water, and a cold wash only 0.4 kWh — the drum motor and nothing else. So drying that load costs 1.3× the warm wash and 6× the cold one. If you are trying to cut the laundry bill, the dryer is where the money is. Full numbers on cost to run a washing machine.
An all-in-one combo dries for more, not less
A ventless condenser combo removes about 0.8 kg of water per kWh against 1.0 for a vented dryer, so it spends roughly 25% more electricity on the same load — and on a 120V outlet it takes hours to do it. The convenience is real; the saving is not. See cost to run a washer-dryer combo for the cycle-length arithmetic.
One dryer load is 3 hours of ironing
A 1,500W iron only draws its nameplate while the element is on, which is roughly 50% of a session — about 0.75 kWh an hour. That makes a single 45-minute dryer cycle worth 3 hours at the board. Ironing is not what is on your bill: cost to run a clothes iron.
Why Dryers Cost What They Do
Heat is what costs money
Roughly 90% of a dryer's electricity goes to the heating element. The drum motor only draws 200-400W on its own — which is exactly what a gas dryer uses, since it buys its heat elsewhere. That is why air-drying or running shorter cycles cuts the bill so directly: you are skipping the expensive part.
A vented dryer constantly heats fresh air
Standard vented dryers pull room air in, heat it, run it through wet clothes, then blow the warm humid air outside. Every minute of heat is dumped out the vent. A heat pump dryer recycles that air through a closed loop, which is why it uses roughly half the energy per load.
Most of the dollar lever is cycle length
You pay for runtime, not the rated wattage. A clean lint screen, an unblocked vent hose, a properly spun load from the washer, and a moisture sensor cycle that stops as soon as clothes are dry all shorten the cycle. Five extra minutes on every load is about $10 a year for a household doing 5 loads a week.
Tips to Lower Your Cost
Clean the lint screen every load
A clogged filter restricts airflow and adds 5-10 minutes to every cycle. It is the single highest-ROI dryer habit.
Use the moisture sensor cycle
Auto-sensor cycles shut off as soon as clothes are dry, saving 10-15% versus a fixed-time setting that overdries.
Spin clothes longer in the washer
A high-spin wash removes more water, so the dryer runs fewer minutes. This alone cuts dryer time by 10-20%.
Air-dry when you can
Skipping half your loads in favor of a rack or line cuts annual dryer cost roughly in half. See our energy savings guide.

Ways to Cut Your Dryer Bill
The biggest electric bill lever for a dryer is reducing total minutes of heat. Heat pump dryers, moisture sensors, and even free drying racks all do that in different ways.
Heat Pump Dryer
Most efficient electric
Heat pump dryers use roughly half the electricity of a vented dryer by recycling warm air instead of constantly heating fresh air.
Vented Electric Dryer with Moisture Sensor
Auto-stop when dry
A moisture sensor shuts the cycle off as soon as clothes are dry instead of running a fixed timer — typical savings of 10-15% per load.
Retractable Indoor Drying Rack
Free air-dry option
Air-drying even half your loads cuts your annual dryer cost roughly in half. A wall-mounted rack tucks away when not in use.
Wool Dryer Balls
Shorter cycle times
Wool balls separate clothes so hot air circulates better, shortening drying time by 10-25% per load with no extra electricity.

Frequently Asked Questions
How much does it cost to run an electric dryer per load?
A standard 3,000W vented electric dryer running a 45-minute cycle uses about 2.25 kWh. At the US average rate of $0.16/kWh, that is roughly $0.36 per load. Households doing 5 loads a week spend about $7.80 a month, or around $94 a year, just to dry clothes.
Does using a lower heat setting really cut the cost?
A little, but less than people expect. Lower heat means the heating element cycles off more often, so average power draw drops. But cooler air also takes longer to evaporate water, so the cycle runs longer. Net savings are usually 10-25%, not half. The bigger lever is reducing total runtime — use a moisture sensor cycle (auto-stop when dry) and clean the lint filter every load so air moves freely.
Is a heat pump dryer worth it?
If you dry a lot of laundry, yes. A heat pump dryer draws about 1,000W against 3,000W for a vented electric, and although its cycle runs longer — nearer 70 minutes than 45 — it still finishes the load on about 52% of the electricity. For a household doing 7 loads a week at $0.16/kWh that is roughly $63 a year saved. They cost more upfront ($1,000-$1,500 vs $500-$800), so the payback is long at the US average rate and much shorter in a high-rate state.
How much cheaper is a gas dryer?
A gas dryer still draws about 350W of electricity for the drum, blower and controls, but it buys its heat by the therm: roughly 0.17 therms a load from a 22,000 BTU/hr burner. At $1.50/therm and $0.16/kWh that is $0.29 a load against $0.36 for a standard vented electric — about 20% less. The gap depends almost entirely on your two utility prices: gas breaks even with electric at around $0.12/kWh, so the cheaper your electricity the weaker the case for gas.
Do dryer balls or aluminum foil really save electricity?
Wool dryer balls do save a bit — they separate clothes so hot air circulates better, cutting cycle time by 10-25%. That is real money over a year. Aluminum foil balls do the same thing and also reduce static, but they wear out. Dryer sheets do not affect drying time and can actually coat the lint filter and reduce airflow, which makes the dryer run longer.
