What is the Salary Proration Calculator (Part Month Salary)?

If you join a company on the 16th, you do not get the full month's salary. The same is true for your last month, or a month with loss of pay (LOP) leave. The salary is prorated, which means paid only for the days counted.

Companies count days in different ways: the real days in the month, a fixed 30 days, a fixed 26 days, or only working days. Enter your salary, pick the month and your company's method, and see your salary for that month, your per-day pay and the amount cut.

How to use it

  1. Enter your monthly basic, HRA and other allowances.
  2. Pick the salary month and why it is a part month.
  3. Enter the joining or last day, or the LOP days.
  4. Choose your company's day counting method.

Frequently asked questions

How is salary calculated for 15 days?
Salary for the month ÷ days counted by your company × days worked. With the calendar method in a 30-day month, 15 days = half the salary.
What is the 26-day method?
Some companies divide the monthly salary by 26 (days without Sundays). Each working day then pays a bit more, and Sundays in your joining period are not paid.
What does LOP mean?
Loss of Pay. It is leave you take without having paid leave left, so that day's salary is cut.
Which method does my company use?
Check your appointment letter or payslip, or ask HR. Calendar days and fixed 30 days are the most common in India.
