A juicer is used to extract juice from fruits, wheatgrass or vegetables. The average price of a juicer depends on the brand name of the juicer, the size of the juicer and the store in which it is bought. On average, the cost of a juicer is $100. With this said, the price you spend should reflect the quality you demand in the product. If you plan to use the juicer on a daily basis, a higher-end model might be best, which cost roughly $150 to $300 each.
