The cost to send money using Western Union varies based on the amount of money sent and the sending and receiving locations. Fees also vary by the method chosen to send the money as well as where and how the recipient receives the money, according to the Western Union website.
As of 2015, sending $100 within the United States by delivering cash to an agent and having the money received in-person at a destination agent costs $12 and is available to the receiving party in minutes. Sending $100 through an agent for pickup one to three days later costs $10, as stated on the Western Union site.
Sending $100 from an agent for deposit into a bank account within two days costs $8, according to Western Union.
