Appliance Life Expectancy
Most appliances and small electrical products have fairly predictable life expectancies. Depending on the original cost, manufacturing quality, and how heavily it´s used, an appliance may last a longer or shorter period than shown in the following table.
Nevertheless, it´s useful information, especially if you want to make sure you get your money´s worth. Just knowing that the microwave is going to die after only 10 years, or that you need to budget for a replacement for your gas range after about 20, helps plan for the inevitable expense. And if you are buying used appliances, it´s a good indicator of how long you can expect a five-year-old top-loading washer to last.
The following table shows average life expectancies for common household appliances. This information has been derived from different sources including manufacturers´ websites and consumer resources, and is intended only as an estimate. Care and maintenance as well as proper installation also play big roles in performance and longevity.
