Online Erlang Calculators

The free online Erlang calculators can be used to make capacity planning calculations. Erlang C is a safety staffing model that takes fluctuations in the number of arrivals and handling times into account. However, it has its limitations in modern-day contact centers. Therefore, we recommend Erlang X, which takes abandonments and retrials into account as well.
