A good method for determining an asking price for used washers and dryers is to estimate their current value. Divide the original purchase price by 10, the average lifespan of the appliances in years, and multiply the result by the number of years remaining until the 10-year mark.
Household appliances depreciate in value over time and with use in the same way as automobiles and other equipment. Estimating the current value of the appliances relative to their age is a good starting point for an asking price, but the current condition and usage history also have an impact on that price. Heavy usage, physical damage and poor maintenance all lower the value of the appliance.
