LOP calculator
Work out the loss of pay for unpaid days, the way Indian payroll does it, with every step shown. Free, no sign-up, and nothing you type leaves your browser.
The LOP formula
LOP deduction = monthly salary ÷ days × LOP days, where “days” is 30 for every month (the most common), the days in that month, or 26 working days.
Example: ₹30,000 a month, 2 LOP days, 30-day basis: ₹30,000 ÷ 30 = ₹1,000 a day, so the deduction is ₹2,000. LOP days are absent days without leave plus unpaid leave, with a half day counting 0.5.
How LOP is worked out
Start from one day’s pay: the monthly salary divided by a fixed number of days. Most Indian companies use 30 for every month, so ₹30,000 is ₹1,000 a day and 2 LOP days cut ₹2,000. On the days in the month, the same 2 days cut ₹1,935 in a 31-day month and ₹2,143 in February. On 26 working days, a day is ₹1,154, and 2 days cut ₹2,308.
LOP days are the days absent with no paid leave left: a full day counts 1 and a half day counts 0.5. Weekly offs and holidays aren’t LOP. Many companies also turn repeated late marks into half days of LOP; the late mark calculator works that part out.
Before you deduct
Pick one way of dividing the salary, write it into the appointment letter or salary policy, and use it every month: mixing 30 days with the days in the month makes the same absence cost different amounts. Absence from duty is one of the deductions the Code on Wages, 2019 allows; for the details in your state, check with your CA or HR adviser.
The hard part is usually the count, not the sum: who was absent which day, who was on leave, who left at lunch. A register gets argued over at month end.
Timerfly counts LOP days for you from your team’s computers. Absent days, half days and approved leave are marked against each person’s hours, and the monthly payroll Excel has loss of pay and paid days for everyone.
Questions
What are LOP days?
The days in a month that aren’t paid: absent days without leave, unpaid leave, and half of each half day taken without leave. 3 absent days and 1 unpaid half day make 3.5 LOP days.
How do you mark LOP?
In the attendance record for the month, mark each day absent without approved leave, and each day of unpaid leave, as LOP (a half day as 0.5). At month end, add them up and send the total to payroll with the paid days.
What is LOP in salary?
Loss of pay: days an employee is absent without paid leave left, so that day’s salary isn’t paid. On a payslip it shows as LOP days and a deduction.
How is LOP calculated?
One day’s pay is the monthly salary divided by a fixed number of days, then multiplied by the LOP days. With ₹30,000 and 30 days, a day is ₹1,000, so 2 LOP days cut ₹2,000.
Should LOP use 30 days or the days in the month?
Both are common. 30 for every month is simplest and the most used. The days in the month makes a day in February worth more than a day in March. 26 working days leaves out Sundays and makes each day worth more again. Use whatever your appointment letter or salary policy says, and keep it the same every month.
Does LOP apply to the whole salary or only basic?
Usually to the whole monthly salary (gross), since every part of it is paid for the days worked. Some companies apply it to fixed parts only and leave reimbursements alone. PF and ESI then follow the lower earned wages.
Is a half day absent half a day of LOP?
Yes. A half day without leave is 0.5 LOP. Many companies also turn repeated late marks into half days; the late mark calculator works that out.
