Your daily rate is your annual salary divided by the number of days you are paid for in a year — not your monthly salary divided by the days in a month. The two are different, and only the first is the rate overtime, holiday and leave pay are computed against. The hourly rate follows from the daily rate and your ordinary hours.
Because months are not the same length. Dividing the annual salary by the paid days in a year gives one rate that holds all year; dividing a monthly salary by the days in that particular month gives a rate that changes every month, and it is not the rate premiums are computed against.
It depends on your contract. 261 assumes Monday to Friday with rest days unpaid, 313 assumes a six-day week, and 365 assumes every day is paid. Your payslip or contract will say; if it does not, ask HR rather than guessing.
No. Enter basic pay only. Overtime, night differential, holiday premium and allowances are computed from the rates this gives you, not included in them.
The factor changes the answer substantially, which is why it is a choice and not a constant.
