Free Per Day Salary Calculator
Work out one day's salary and the pay for days worked, on the calendar-day, 30-day and 26-day basis.
Quick answer
Per-day salary = monthly salary ÷ the number of days your policy uses. There are three common bases: calendar days in that month (₹15,000 ÷ 30 = ₹500 in November, ₹15,000 ÷ 31 = ₹484 in October), a fixed 30 days (₹500 every month), or 26 working days (₹577, because Sundays are paid). The same absence costs a different amount under each method, so write the method in the appointment letter and use it every month.

Frequently asked questions
How do I calculate one day salary from monthly salary?
Divide the monthly salary by the days in your pay basis. For ₹18,000 a month: ₹18,000 ÷ 30 = ₹600 per day on a 30-day basis, ₹18,000 ÷ 26 = ₹692 on a 26-day basis, or ₹18,000 ÷ 31 = ₹581 in a 31-day month on the calendar-day basis.
Should I divide salary by 26 or 30 days?
Neither is mandated for all employers. Dividing by 26 treats Sundays as paid holidays and gives a higher daily rate, so each absence costs the employee more. Dividing by 30, or by the actual calendar days, gives a lower daily rate. Gratuity and leave encashment are normally worked out on 26 days. Pick one basis, put it in writing, and apply it to everyone.
How much salary is cut for one day of absence?
One day's rate on your chosen basis. On ₹15,000 a month that is ₹577 (26-day basis), ₹500 (30-day basis), or ₹484 to ₹536 depending on the month (calendar-day basis).
