How do you find the average cost of an iPhone 5?

As of 2015, determine the average cost of an iPhone 5 by averaging price figures from websites such as Amazon.com, Best Buy and eBay. The original iPhone 5 is no longer available from Apple. Prices for used models vary depending on the condition of the product.

iPhones are often available for a reduced price when purchased with a contract with a phone service provider. The amount of internal storage on the phone also affects the price.

According to Digital Trends, the most current used prices for a 16GB iPhone 5 on Verizon range from $165 to $250. These prices may depend on the condition of the phone or the reputation of the seller.

Best Buy's website lists a number of iPhone 5s for sale with two-year service contracts. With a contract, an iPhone 5 with 64 GB of memory costs $200, while an iPhone 5 with 32 GB of memory costs $100. An iPhone with 16 GB of memory costs $50.
