What is an Electric vs Gas Appliance Calculator?
An Electric vs Gas Appliance Calculator is a free environmental tool that helps you compare the operating costs and environmental impact of electric and gas-powered home appliances. It determines which energy source is more cost-effective and eco-friendly for your specific situation.
This calculator works for:
- Water heaters - Compare tank and tankless electric vs gas models
- Heating systems - Furnaces, space heaters, and baseboard heaters
- Clothes dryers - Electric resistance vs gas dryer operating costs
- Stoves and ovens - Cooking appliance energy comparison
To understand your home energy consumption patterns, check out our Carbon Footprint Calculator to calculate your total household emissions and identify reduction opportunities.
For planning solar energy to power electric appliances, explore our Solar Panel ROI Calculator to determine if solar panels can offset your electricity costs and make electric appliances more economical.
To track your household water heating costs in detail, use our Water Usage Calculator to monitor consumption patterns and optimize your water heating efficiency.
How This Calculator Works
The calculation uses these formulas:
Where:
- Usage = Based on appliance type efficiency and daily usage hours
- Electricity Rate = Your local utility cost per kilowatt-hour
- Gas Rate = Your local natural gas cost per therm
- Emission Factor = CO2 produced per unit of energy consumed
Key Concepts Explained
Energy Efficiency
Electric appliances often have higher efficiency ratings (90-98%) compared to gas appliances (80-90%), meaning less energy is wasted as heat.
Emission Factors
Natural gas produces about 5.3 kg of CO2 per therm burned, while electricity emissions depend on your local power grid's fuel mix.

Factors That Affect Your Results
1. Local Energy Rates
Electricity and gas prices vary significantly by region and utility provider.
2. Appliance Efficiency
Newer models are typically more efficient than older units, affecting both cost and emissions.
3. Usage Patterns
How often and when you use appliances impacts annual operating costs.
4. Climate
Cold climates may favor gas heating, while mild climates work better with electric heat pumps.
Frequently Asked Questions (FAQ)
Q: Which is more cost-effective: electric or gas appliances?
A: Generally, gas appliances have lower operating costs for heating applications like water heaters, furnaces, and stoves. However, electric appliances are becoming more cost-effective with improving technology and may have lower installation costs. The calculator helps you compare based on your local energy rates and usage patterns.
Q: Are electric appliances better for the environment?
A: Electric appliances produce zero emissions at the point of use, but their overall environmental impact depends on how the electricity is generated. In areas with clean energy sources, electric appliances have a lower carbon footprint. The calculator compares CO2 emissions based on your local electricity grid's emission factor.
Q: What appliances should I consider switching from gas to electric?
A: Common appliances to consider switching include water heaters, space heaters, clothes dryers, stoves/ovens, and furnaces. Heat pump technology has made electric versions of these appliances much more efficient. Consider your climate, local energy costs, and whether you're building new or replacing existing appliances.
Q: How accurate are the cost comparisons in this calculator?
A: The calculator uses standard energy conversion factors and average efficiency ratings to provide estimates. Actual costs will vary based on your specific appliance models, usage patterns, maintenance, and local utility rate structures. Use the results as a starting point for comparison and consult with local contractors for precise estimates.
Q: Do I need to consider installation costs when comparing electric vs gas?
A: Yes, installation costs can significantly impact the overall comparison. Gas appliances require gas line installation or connection, ventilation systems, and sometimes additional safety equipment. Electric appliances need proper electrical circuits and may require panel upgrades. These upfront costs should be factored into your decision along with long-term operating costs.
