In 1906, Italian economist Vilfredo Pareto created a mathematical formula to describe the unequal distribution of wealth in his country, observing that 20% of the people owned 80% of the wealth. This became known as the 80/20 Rule, and is now widely used in many organizations as a benchmark of good quality practice.

In the world of telephone sales, the 80/20 Rule means that only a few calls we make (20%) are vital and many (80%) are trivial, reminding us to focus our efforts on the 20% that matters. Those 20% produce 80% of your results.

The Sales Call Calculator enables you to calculate how many sales calls are required to hit your weekly sales targets, based on the 80/20 rule of sales conversion.

Simply add in your weekly sales target (£), your current level of sales activity and the average value of a typical successful sales call, and let the calculator tell you whether or not you are on track to hit your targets.
