How LOP is calculated
Payroll first works out a per-day rate, then multiplies it by the LOP days. The per-day rate depends on the company's chosen basis. Some divide the monthly gross by the calendar days in that month, others by the working days, and many use a fixed divisor such as 30 or 26. With a gross of ₹31,000 in a 31-day month on a calendar basis, one LOP day costs ₹1,000. The same salary on a fixed 26-day basis costs about ₹1,192.31 per LOP day, rounded to two decimals. That gap is why the basis belongs in the written policy.
Loss of pay versus leave without pay
The two terms are often mixed up. Leave without pay is a type of leave that the employee asks for and the manager approves, for example ten unpaid days to care for a parent after paid leave is exhausted. Loss of pay is the salary effect of any unpaid day. Every approved LWP day creates LOP, but LOP can also come from days nobody approved: unauthorized absence, a missing punch treated as absent, or a late-mark penalty. The difference matters beyond payroll, because approved LWP is not misconduct, while repeated unexplained absence can be.
Keeping LOP accurate
Most LOP disputes come from timing and visibility. Deductions must also respect the rules on deductions from wages. In ZeniaHR, the deduction policy sets the loss of pay basis as working days, calendar days, or a fixed 30, 26, 24 or 22 days, and paid days come from the finalized attendance month.
- Freeze attendance before payroll so LOP days do not change after salaries are computed
- Show LOP days and paid days on the payslip
- Limit LOP to the days between joining and exit dates in the month
- Reverse a wrong LOP as an arrear in the next payroll, with a note

What does LOP mean in a salary slip?
LOP on a salary slip means loss of pay: the number of days in the month for which salary was not paid. The payslip usually shows LOP days next to paid days, and gross earnings are reduced in proportion. If you see LOP you did not expect, check your attendance and leave records for that month and raise it with HR before the next payroll.
Is LOP calculated on basic or gross salary?
Most companies calculate LOP on the monthly gross, so every component, such as basic, HRA and special allowance, is reduced by the same share. Some calculate it on selected components only. The method, and the divisor used for a day's pay, should be written in the payroll policy so that the same absence costs every employee the same share of salary.
What is the difference between LOP and LWP?
LWP, leave without pay, is approved unpaid leave that the employee asked for. LOP, loss of pay, is the salary deduction for any unpaid day, whether it came from approved LWP, unauthorized absence or an attendance penalty. So every LWP day becomes an LOP day in payroll, but not every LOP day was an approved leave.
