Loss of Pay (LOP) Calculation from Attendance

Loss of pay is where attendance and payroll meet, and where many salary complaints start. Direct Payroll reads paid days from the attendance month HR has finalized, including penalty days from your attendance rules, and prorates each salary over the calendar days of the month. The deduction policy decides how half days, absences, leave without pay, weekly offs and holidays are paid, and every payslip shows payable days, working days and LOP days.

How it works

Set the Attendance and Salary Deduction Policy in Settings, Statutory Payroll Rules: half-day pay, absent-day deduction, LWP deduction, weekly-off pay and holiday pay.
Finalize the month in Attendance. This freezes each person's present, half, absent, leave, weekly off and holiday days, and the penalty days from the attendance rules.
When a run is created, paid days are present days, paid rest days and paid leave, plus half days at the half-day pay percentage, less penalty days.
The earned gross is the monthly gross multiplied by paid days and divided by the calendar days of the month.
Joining and exit dates bound the paid days, so a joiner on the 16th of a 30-day month earns 15 of 30 days.
If the month is not finalized, the draft reads the older attendance records instead, and a banner on the run says the month is not finalized.

What you can set

Half-day pay (%): the part of a day paid for an attendance half day, 50 percent by default.
Absent-day deduction (days): salary days lost per absent day, 1 by default.
LWP deduction (%): the part of a leave without pay day deducted, 100 percent by default.
Weekly-off pay and holiday pay: paid or unpaid, both paid by default.
Sandwich policy: weekly offs and holidays bridged by absence become unpaid, off by default.
Penalty days from the attendance rules, such as late marks turning into half days, come off the payable days.
Every policy save is a new version with an optional reason, listed in version history with who changed it.

Why LOP disputes happen and how to avoid them

Many LOP complaints come from two versions of the truth: the muster the supervisor kept and the figures payroll used. A late correction, a half day counted as full, a weekly off treated as unpaid, and the employee's pay no longer matches what they were told. Direct Payroll reads one frozen month, applies one written policy, and prints the payable, working and LOP days on the slip. Keep the policy consistent with your standing orders and the rules on deductions from wages.

Worked example: September 2026 in Pune

Kiran earns a monthly gross of ₹36,000. September 2026 has 30 days: 8 weekend days, one company holiday on Monday 14 September and 21 working days. Kiran has 19 present days, 1 half day and 1 unpaid absence. With the default policy, weekends and the holiday are paid and a half day pays 50 percent, so paid days are 19 + 8 + 1 + 0.5, which is 28.5. LOP is 1.5 days and the earned gross is ₹36,000 x 28.5 / 30, or ₹34,200.

Kiran also collected late marks, and the attendance rules turned them into a half-day penalty in the finalized month. Paid days drop to 28 and the earned gross to ₹33,600. Had the policy paid half days in full, paid days before the penalty would have been 29, worth ₹34,800. Each day is worth ₹1,200 in September because the gross is divided by 30.

Policy settings that keep LOP fair

Decide the half-day pay percentage once and publish it. Think carefully before making weekly offs unpaid for monthly salaried staff, since it changes pay sharply in months with five weekends. Use the monthly penalty cap in the attendance rules so late marks cannot swallow a salary. Finalize attendance only after corrections are approved, and if something changes later, reopen the month with a reason, fix it and finalize again before the run.

Frequently asked questions

How is loss of pay calculated in Direct Payroll?

LOP days are the calendar days of the month minus paid days, and each is worth the monthly gross divided by the calendar days. With a ₹36,000 gross in a 30-day month, a day is ₹1,200, so 1.5 LOP days cost ₹1,800 and the earned gross is ₹34,200.

What is the difference between LOP and LWP?

LWP, or leave without pay, is approved leave taken when paid balance runs out. LOP, loss of pay, is the pay lost for any unpaid day, whether it came from LWP, an unapproved absence or an attendance penalty. In ZeniaHR, LWP is a leave type and LOP days print on the payslip.

Does Direct Payroll divide salary by 26 days?

No. By default Direct Payroll prorates over the calendar days of each month, so September divides the monthly gross by 30 and October by 31. Paid weekly offs and holidays count as paid days, so a person with full attendance always receives the full monthly gross.

Are attendance penalties deducted from salary automatically?

Yes, once the month is finalized. Penalty days from your attendance rules, such as late marks that turn into half days, are part of the frozen month and come off the payable days in the payroll run. HR can waive a penalty with a reason before finalizing the month.
