The Pay Trends graph plots total employee net pay over the most recent pay runs. This includes the current one.
It also plots the total cost to the employer of employees’ pay.
The graph is a useful visual way of seeing unexpected pay changes.
EXAMPLE:
For example, if all employees are on a fixed pay rate, you expect the total employee net pay value not to change. If you do see an unexpected change, this can be due to a pay processing error.
