How do I calculate the operating cost for an electric dryer?
The formula is: Cost = (Wattage × Load Time in hours × Electricity Price per kWh) ÷ 1000. For example, a 5,000 W dryer running for 45 minutes (0.75 hrs) at $0.13/kWh costs about $0.49 per cycle. See also our HVAC Sizing Calculator (Green).
How do I calculate the operating cost for a gas dryer?
A gas dryer has two energy costs: electricity for the motor and gas for the burner. The formula is: Cost = [(Motor Wattage × Electricity Rate) + (BTU Rating × Gas Rate ÷ 100,000)] × Load Time in hours ÷ 1000. The BTU rate is divided by 100,000 because gas is priced per therm (100,000 BTU).
Are gas dryers cheaper to operate than electric dryers?
In most U.S. regions, yes — gas dryers typically cost 50–75% less per cycle than electric dryers because natural gas is cheaper per unit of energy than electricity. However, gas dryers usually have a higher upfront purchase price, so the payback period matters when evaluating total cost of ownership.
How much does it cost to run an electric dryer per year?
Running a typical 5,000 W electric dryer for 45 minutes, 5 loads per week, at $0.13/kWh costs roughly $95–$130 per year. Your actual cost depends on your local electricity rate, dryer efficiency, and how often you do laundry. You might also find our use the EUI (Energy Use Intensity) Calculator useful.
What is a typical BTU rating for a gas dryer?
Most residential gas dryers have a burner rated between 18,000 and 22,000 BTU per hour. High-efficiency or heavy-duty models may go up to 25,000 BTU/hr. Check your dryer's energy guide label or owner's manual for the exact figure.
Does dryer efficiency affect the cost comparison?
Yes. Older or poorly maintained dryers may take longer per cycle, increasing energy use. Cleaning the lint trap before every load, ensuring proper venting, and not overloading the drum all reduce drying time and operating costs for both electric and gas models.
Which dryer type is better for the environment?
It depends on your region's electricity mix. Where electricity comes largely from renewables, an electric dryer (especially a heat pump model) can have a lower carbon footprint. In areas where the grid relies heavily on coal or gas, a natural gas dryer may produce fewer emissions per cycle.
Can I switch from an electric dryer to a gas dryer to save money?
Switching can save money long-term if gas rates are significantly lower in your area, but you need a gas line installed if one isn't already present — this can cost $200–$700 or more. Factor in installation costs and appliance price differences when calculating your break-even point. Check out our find Annual Phantom Load Cost with Phantom Load Calculator as well.
