The salary due for a part month, when someone joins after the 1st or leaves before the month ends.
An employee who joins or leaves mid-month is paid for the days they were on the rolls, not the whole month. The pro-rata salary is the monthly salary multiplied by paid days over the month's divisor.
This pro rata salary calculator lets you choose the divisor your payroll uses, so the joiner's first payslip and the leaver's settlement are worked out the same way as every other month.
Enter your figures, then press Calculate
Your 5 inputs become a full breakdown, with every step of the working shown beneath the headline figures.
Paid days over the month's divisor, times the monthly salary. The divisor is the only judgement, and it should be the same one your payroll uses for LOP.
Pro-rata salary = Monthly salary × Paid days ÷ Divisor
For a joiner, from the joining date to the month end. For a leaver, from the 1st to the last working day. Count them on the same basis as the divisor: calendar days with calendar days, working days with working days.
Calendar days in the month, working days, or a fixed 30 or 26. It should match your LOP basis so that part months and absences are treated alike.
Multiply the monthly salary by paid days and divide by the divisor. Apply the same fraction to each salary component.
What this does not include
Asked often enough about this calculation to be worth answering beside it.
Count the days from the joining date to the end of the month, inclusive, then multiply the monthly salary by those days and divide by the month's divisor. A joiner on the 13th of a 30-day month has 18 paid days.
Either is used in practice. Actual calendar days gives a slightly different day rate each month; a fixed 30 keeps it constant. Use whichever your payroll uses for LOP so the two stay consistent.
On a calendar-day basis, yes: weekly offs that fall after the joining date are paid. On a working-day basis, count only working days in both the paid days and the divisor.
Yes. Paid days run up to and including the last working day.
A calculator applies a rule to figures you type in. A payroll run applies it to your actual employee record, your locations and your verified declarations, which is where Professional Tax, LWF and TDS also resolve.
