In the case of  antiques or valuable collections, consult pricing guides at the library or online or ask an expert. Visiting local consignment stores and looking at newspaper and internet ads for similar objects can also give you an idea of how much your furniture is worth. Compare this information with the used furniture calculator.

Even if your furniture is not old enough to be classified as antique or have value as a collector's item, it is still worth something. Consider how much you paid for it, who manufactured it, how long you have used it and its present condition. Input this information into the used furniture calculator.

Another fact worth remembering is that upholstered furniture is the hardest to sell, and you will have more takers for case goods.

Contact a professional liquidator if you have a lot of furniture to sell, and they will suggest the best method for disposing of your furniture. They might suggest an on-site auction, moving everything to an auction house, or having a tag sale. They will set the prices for all items, and you can expect them to charge 20 to 30 percent of the sale proceeds. Go through all costs and commissions before you sign any agreements. To find liquidators in your area look online under "estate sales."

If you are left with items you were unable to sell, consider donating to charities or furniture banks. You get the satisfaction of helping someone and receiving a tax break.
