My new employee's first day of work was 25th September. Is my calculation for his salary(RMX) this way? RMX/30*6 calendar days, or RMX/30*4 working days, or RMX/26*4 working days?
Also, My employee's last day was 18th September. Is my calculation for his salary (RMX) this way? RMX/30*18 calendar days, or RMX/30*12 working days?
The easiest way is to use (salary/days in the month) x calendar days. You can of course use other methods as long as they give accurate amount or more or less the same as using calendar days.
