Pro-rata salary is what you actually get paid when you don’t work a full month, a joiner starting mid-month, a leaver whose last working day falls somewhere in the middle, or anyone on loss of pay for part of the period. There’s no single legally mandated formula for this in India, which is exactly why the method matters.

The three common methods

Indian payroll practice generally uses one of three divisor conventions, and they don’t all give the same answer for the same partial month:

• Fixed 30-day divisor: monthly salary ÷ 30 × days worked, regardless of the actual number of days in that calendar month
• Actual calendar-day divisor: monthly salary ÷ the real number of days in that month (28, 29, 30 or 31) × days worked
• Working-days-only divisor: based only on actual working days, excluding weekly offs, sometimes using a 26-day convention

Take a monthly salary of ₹60,000 and 16 days worked in a 30-day month. On the fixed 30-day method, that’s ₹60,000 ÷ 30 × 16 = ₹32,000. The other two methods can land close to this or noticeably different depending on the specific month and the company’s exact convention, which is why it’s worth confirming which method your payroll actually uses rather than assuming.

Frequently asked questions

Does the method change PF and other statutory deductions?

Yes. Since PF, professional tax and similar deductions are calculated on the pro-rated wage, a different divisor method changes not just gross pay but the deductions that flow from it too.

Is one method more “correct” than the others?

No single method is legally mandated for general pro-ration, so none is inherently more correct. What matters is that your company applies its chosen method consistently, since inconsistency between employees or months is what actually causes disputes.
