Methodology
How this tool works
The calculator uses total basic salary earned during the calendar year divided by 12.
Monthly mode adds only the basic salary rows you enter, which is safer for partial-year, unpaid leave, resigned, or separated employee scenarios than a simple months-worked shortcut.
Direct mode is for payslips, HR records, or final-pay computations where the total basic salary earned for the year is already known.
Allowances, overtime, premium pay, night differential, holiday pay, unused leave conversion, and COLA are excluded unless your agreement, company practice, or policy treats them as part of basic salary.
