    Hello,

    I currently work for a fairly large call center and we are attempting to forecast our abandon rate for any given day.

    Currently we forecast for staffing levels, off phone work, call handle time and service level. Ultimately we would like to brake abandon rates down into half hour intervals like our service level, but an overall abandon rate for the day would be fine.

    Is there a way we could calculate this based on the forecast day?

    Thank you.

    No one can accurately predict abandonment rate as there are too many factors involved. How long would you wait for a sales line, for a claims line, on a freephone line, staff available when you call, sudden surges in calls etc

    However if you do want to try, there are free calculators on the internet where you can specifiy the time that callers will wait before giving up. you can then for any given call volume and handle time, estimate the number of abandoned calls.

    Abandons will vary depending on the business you are in, the cost of the call and how important it is to the customer that they speak to you, the ease of alternatives, e-mail, quality of your queue messages/music.
    If I need your help, I will wait for a long time, if I am buying from you and you dont answer, I probably wont wait for so long.

    Standard Erlang assumes callers will wait for ever but there are versions out there that will estimate abandon rates for you if you really need it.

    You could use look up table based on your historical data. IT may be that 100 call generates 2 abandoned calls,125 generates 15 etc etc

    Is there a calculator to calculate the staffing which can look at BOTH % of calls answered within specified time and the abandonment rate (65% of calls answered within 20 sec and less than 5% abandonment – calls abandon after 20 secs)

    -Can you tell me correct or incorrect: AHT=7*(60*60)*65%/20

    if incorrect you tell me caculation “Average short message broadcasting traffic of each user ”

    thank alot
