Energy Cost Equations:
| From: | To: |
This calculator compares the operating costs of gas versus electric clothes dryers based on energy usage and local utility rates. It helps consumers make informed decisions about which type of dryer would be more economical to operate in their area.
The calculator uses these simple equations:
Where:
Explanation: The calculator multiplies your dryer's energy consumption by your local utility rates to determine operating costs.
Details: Choosing the right dryer type can lead to significant long-term savings. While gas dryers typically have higher upfront costs, they often have lower operating costs in many areas.
Tips: Enter your dryer's energy usage (found in the manual or energy guide label) and your local utility rates (found on your bill). All values must be non-negative numbers.
Q1: Which is generally cheaper to operate?
A: Gas dryers are typically cheaper to operate in most areas, but this depends on local utility rates.
Q2: Where can I find my dryer's energy usage?
A: Check the EnergyGuide label on your dryer or the manufacturer's specifications. Typical values are 3-4 therms/month for gas or 150-300 kWh/month for electric.
Q3: Should I consider other factors besides cost?
A: Yes, also consider installation costs (gas requires a gas line), environmental impact, drying time, and maintenance requirements.
Q4: How much can I save by choosing the cheaper option?
A: Savings vary but typically range from $50-$150 per year depending on usage patterns and local rates.
Q5: Do these calculations account for efficiency differences?
A: The calculations assume you've entered accurate usage data for comparable dryers. Actual efficiency varies by model.
