The main changes in Version 5.5 is a bug fix affecting calculations below 1 erlang of traffic intensity.
In Version 5.4 we added the ability to handle higher call volumes, addition of dynamic charts for the Day Planner and Expected Service Level charts – so you can add on extra rows.
Erlang Theory is named after the Danish mathematician Agner Krarup Erlang (1 January 1878 – 3 February 1929) , who invented the fields of traffic engineering and queueing theory.
He published his Erlang C formula in 1917 and it has been widely used ever since.

There is no need to install an add-in as the macro is stored in the worksheet.
This uses the Excel Formula =Agents Req(Calls, Reporting_period, Average_Call_duration, Service_level_percent, Service_level_time) For example =Agents Req(B9, C9, D9, E9, F9) Please note that this does not include any Shrinkage (holidays, training, meetings, etc.) This uses the Excel Formula =Agents FTE(Calls, Reporting_period, Average_Call_duration, Service_level_percent, Service_level_time, Shrinkage) For example =Agents FTE(B30, C30, D30, E30, F30, G30) This formula is more accurate as it includes Shrinkage (holidays, training, meetings, etc.) and so gives a more realistic staffing requirement.

We have also developed a Multi-Channel call centre calculator which can mix calls emails and webchat. It has a really nice visualisation that shows the contacts and the calls over time.

The Erlang C formula (which is the one that this Erlang Calculator is based on) is the one used for working out the numbers of agents needed for a given call volume.
