About This Calculator
The Gas vs Electric Dryer Calculator helps you compare the true cost of owning and operating a gas dryer versus an electric dryer. Whether you are buying a new dryer, deciding between gas and electric hookups in a new home, or simply curious about your current appliance's operating costs, this calculator gives you a detailed breakdown including per-load costs, annual operating expenses, and a multi-year total cost comparison that factors in the purchase price of each appliance.
Electric dryers work by drawing air at room temperature and heating it using electric resistance coils, then circulating the hot air through the drum to absorb moisture. Gas dryers use a natural gas or propane burner to heat the air but still rely on electricity for the drum motor, controls, and fan. This means gas dryers have a two-part operating cost: electricity for the motor and gas consumption for heating. The formula used is: Electric cost per load = (wattage × cycle hours × electricity rate) / 1000. For gas dryers: Total cost = (gas dryer wattage × cycle hours × electricity rate / 1000) + (BTU rating × cycle hours × gas cost per therm / 100,000). The annual savings are calculated as the difference between electric and gas annual costs, and the break-even point shows how many years of savings it takes to offset the higher purchase price of a gas dryer.
Regional Notes
India: Electricity rates range from ₹5 to ₹8 per kWh depending on the state. LPG (liquefied petroleum gas) is more common than natural gas for home drying in India. Piped natural gas (PNG) is available in select cities at approximately ₹35 to ₹50 per therm. Electric dryers are less common in Indian households compared to line-drying, but adoption is growing in urban areas. Gas dryer availability is limited and typically requires professional installation with proper ventilation.
United States: The average US electricity rate is about $0.12 to $0.16 per kWh. Natural gas costs average around $1.00 to $1.50 per therm but vary significantly by state. Gas dryers are popular in US homes with natural gas hookups, comprising roughly 20% of the dryer market. Electric dryers are more common and generally cheaper to purchase ($400 to $1,200) compared to gas dryers ($600 to $1,600). Energy Star-certified models can reduce energy consumption by 20% compared to standard models.
United Kingdom: UK electricity rates average around £0.24 to £0.30 per kWh, among the highest in the world. Natural gas costs approximately £0.05 to £0.07 per kWh (around £0.50 to £0.70 per therm). Gas dryers are less common in UK households due to the prevalence of vented condenser dryers and the British preference for tumble dryers that do not require gas hookups. The high electricity costs in the UK make the annual savings potential with gas dryers particularly significant if a gas connection is available.
Frequently Asked Questions
Which is cheaper to run: a gas dryer or an electric dryer?
Gas dryers are typically cheaper to run than electric dryers in regions where natural gas prices are low relative to electricity. Gas dryers use natural gas for heating, which costs less per BTU than electric resistance heating. However, the upfront purchase price of a gas dryer is usually higher, so the break-even point depends on your local utility rates and usage patterns.
How do I calculate the operating cost of an electric dryer?
To calculate the operating cost of an electric dryer: multiply the dryer wattage (in watts) by the cycle time (in hours) and divide by 1000 to get kWh per load. Then multiply by your electricity rate per kWh. For annual cost, multiply the per-load cost by the number of loads per week and then by 52 weeks.
How do I calculate the operating cost of a gas dryer?
The gas dryer cost has two components: electricity for the motor and controls, and gas for heating. Calculate electric cost by multiplying the gas dryer wattage by cycle hours divided by 1000, then by your electricity rate. Calculate gas cost by multiplying the BTU rating by cycle hours divided by 100,000 (to get therms), then by your gas cost per therm. Add both components for the total per-load cost.
What is the average wattage of an electric dryer?
Electric dryers typically have a wattage between 2,000 and 6,000 watts, with most standard models averaging around 3,000 watts (3 kW). Higher-end dryers with moisture sensors and advanced features may use less energy per load despite having higher wattage ratings because they can automatically shut off when clothes are dry.
What is the typical BTU rating for a gas dryer?
Gas dryers typically have a BTU rating between 16,000 and 25,000 BTU per hour, with most standard models rated around 20,000 to 22,000 BTU/h. The gas burner uses natural gas or propane to heat the air, while the electric motor (typically 300 to 600 watts) powers the drum rotation and air circulation.
How many years does it take to break even on a gas dryer?
The break-even point for a gas dryer depends on the price difference between gas and electric dryers and your annual savings from lower operating costs. In the US with average utility rates, a gas dryer typically pays back its higher upfront cost within 2 to 5 years. In India and the UK, where gas prices vary significantly, the break-even period can range from 1 to 4 years. Use the break-even calculation in this calculator for a precise estimate based on your specific rates.
Do gas dryers require more maintenance than electric dryers?
Gas dryers require slightly more maintenance because they have additional components like gas burners, pilot lights or igniters, and gas valves. Annual inspection of gas connections, burner cleaning, and vent cleaning are recommended for safety. Electric dryers are mechanically simpler but can still require heating element replacement. Both types need regular lint filter cleaning after every load.
Which dryer type is better for the environment?
The environmental impact depends on your local energy sources. If your electricity comes from renewable sources, an electric dryer may have lower carbon emissions. Gas dryers burn natural gas directly, producing CO2 and other emissions at the point of use. However, in regions where electricity is generated from coal or natural gas, a high-efficiency gas dryer may have a smaller carbon footprint. Energy Star-certified dryers, regardless of type, are the most environmentally friendly choice.
