Use this tool to calculate the cost of your calling campaign.
Message duration will vary based on the length of the script. The calls that reach answering machines have to repeat the message, resulting in a longer call. This typically balances out calls that are hung up before the end of the message, so actual length of the recorded message is a good guess for your average call duration.
Call completion rate varies with the quality of your phone list, and increases as you allow more time for callbacks. By allowing the system to redial busy and no-answer numbers over several days, a delivery rate of 90% is common. Only successfully connected calls are billed.
