Download the Free Contact Centre (Erlang) Calculator

We have developed a free Erlang Calculator - in handy Excel based Spreadsheet format to help with your call centre staff planning.

This is a simple Excel spreadsheet tool that allows you to work out how many agents you will need. You just need to enter your call volume and the service level that you would like to achieve. The calculator then looks at the agent capacity you would need to achieve the service level.

And because it is all done in an Excel spreadsheet it makes it pretty easy for you to model different call volumes across the course of the day.
