# Relative capacity requirements percent each roleΒΆ

**Percentage per professional role**

This option calculates the percentage by which a demand for an occupational role may have been met or undermet with the available skilled labour.

The capacity utilisation per role is calculated using the formula:

(Actual capacity used/total capacity) x 100

The existing resource capacity is defined as the basis, i.e. how many person-days are available per role, for example, is taken as 100%.

**Percentage of all professional roles**

A percentage share of an occupational role is calculated in relation to a common need for all roles.

(Actual capacity used per roll/total capacity of all rolls) x 100
