The Calculate buttons in Employee Rate Details calculate the other rate fields based on the values entered. The calculation is based on the Pay Frequency selected in Pay Details, Normal Hours Paid and the Rate you choose in Rate Details. You can calculate rates based on Yearly Salary, Autopay Amount or Normal Rate.
Yearly Salary and Auto Pay Amount are calculated to two decimal places. The other rates are to the number of decimal places specified in General Parameters. The default is 4. It is these calculated values that are used in transactions.
For example, when you calculate based on the Yearly Salary:
Auto Pay Amount is calculated by dividing the Yearly Salary by the number of periods in a year.
Normal Rate is calculated by dividing the Auto Pay Amount by Normal Hours Paid.
Conversely, when you calculate based on the Normal Rate:
Auto Pay Amount is calculated by multiplying the Normal Rate by Normal Hours Paid.
Yearly Salary is calculated by multiplying the Auto Pay Amount by the number of periods in the year.
Note: Auto pay transactions use the Autopay amount stored in Rate Details rather than calculating the amount based on the normal rate and normal hours paid. If the Autopay Amount is incorrect (i.e. not equal to normal rate by normal hours paid), then the transaction will be incorrect.
Remove the Autopay Amount on the employee's record if you want auto pay transactions calculated by multiplying the normal rate by the normal hours paid.
