Appliance Savings Calculator
This savings calculator allows you to answer the question "What is a new appliance worth to me?". It factors in the time value of money, tells you what you should pay for the appliance and calculates your real rate of return. If you don't know how much power your appliances consume, use the links to search our database. The database has several thousand entries from ENERGYSTAR® (American), EnerGuide (Canadian), Office of Energy Efficiency (Canadian). If you can't find your model, there are also some generic listings which give you the average annual consumption for appliances made in a particular year.
Instructions:
- Price of new appliance: Optional. If you enter this, the system will calculate your rate of return.
- Annual power need of old appliance in kWh: If you don't know, use the look-up link.
- Annual power need of new appliance in kWh: Look at the tag on the new appliance, or use the look-up link.
- Power cost: Get this from your monthly utility bill. If you pay 12 cents, enter 0.12 .
- Interest rate: The default is 7%. This is the average growth, adjusted for inflation, of the stock market over the last 200 years. We recommend you keep this value. Enter 7% as 0.07 .
- Resale value: What you expect to sell the appliance for (garage sale perhaps) when you get rid of it.
- Expected life: Default is 15 years.
- Annual maintenance: For a refrigerator, you can enter zero. For something like a gas furnace, you might put in the cost of the annual service call.
