How to Use This Attendance Calculator
- 1Enter your Gross Monthly Salary — the CTC-component salary before any deductions (not take-home).
- 2Set the Total Working Days for the month. This is the number of working days in your company's calendar for that month (typically 24–26 for a 6-day week or 20–22 for a 5-day week).
- 3Enter the Days Present — the number of days you actually attended office or worked from home.
- 4Add Paid Leaves (CL/SL/PL) applied and approved for the month. Present Days + Paid Leaves cannot exceed Total Working Days.
- 5View your LOP days, LOP deduction amount, and final net salary instantly.
How LOP Deduction is Calculated
Indian payroll uses a straightforward pro-rata deduction for Loss of Pay (LOP) days. The calculation is based on the number of working days in the month, not calendar days:
LOP Days = Total Working Days − Present Days − Paid Leaves
LOP Deduction = (Gross Salary ÷ Total Working Days) × LOP Days
Net Salary = Gross Salary − LOP Deduction
Present Days + Paid Leaves must not exceed Total Working Days.
LOP Days can never be negative (clamped to 0 if all working days are covered).
Working Days vs Calendar Days
Most companies use actual working days (excluding weekends and public holidays) as the divisor for per-day salary. A few companies use 30 or 26 as a fixed number regardless of the month. The divisor used significantly impacts the per-day rate — always verify with your HR or salary slip.
Leave Priority Order
Most Indian HR policies apply leaves in this order: CL first, then SL, then PL/EL. Leaves applied in excess of balance are converted to LOP. Some companies allow leave without pay (LWP) as a formal request that is approved upfront rather than retroactively marked as LOP.
Worked Example
Software Engineer, Gross Salary ₹60,000, September 2024
| Gross Monthly Salary | ₹60,000 |
| Total Working Days (Sept) | 26 days |
| Days Present | 22 days |
| Paid Leaves (CL used) | 2 days |
| LOP Days (26 − 22 − 2) | 2 days LOP |
| Per Day Rate (₹60,000 ÷ 26) | ₹2,308 |
| LOP Deduction (₹2,308 × 2) | − ₹4,615 |
| Net Salary | ₹55,385 |
Attendance: 92.3% (24 of 26 days). Two LOP days reduced the salary by ₹4,615. Had 2 more CL been available, the full ₹60,000 would have been received.
Common Payroll Mistakes to Avoid
Using 30 days instead of actual working days
Many employees assume per-day salary = monthly salary ÷ 30. But most Indian companies divide by actual working days (e.g., 26). Using 30 underestimates the per-day rate and makes LOP deductions appear smaller than they actually are.
Not accounting for paid leaves before marking LOP
Employees sometimes assume they have LOP when they actually have CL or SL balance available. Always check your leave balance with HR before assuming LOP. Unused approved leaves are paid and should offset absent days before LOP is applied.
Forgetting that LOP affects variable pay and bonuses
LOP does not just reduce your monthly salary — it can disqualify you from variable pay, performance bonuses, and annual increments if your attendance falls below the company's minimum threshold (typically 75–85%). The financial impact of LOP is therefore greater than just the monthly deduction.
Assuming LOP rules are the same across companies
Every company has its own leave policy, approved leave types, and LOP calculation method. Some use calendar days as the divisor, some use working days. Some carry forward unused leaves, others don't. Always read your offer letter and HR policy document rather than assuming industry-standard rules apply everywhere.
Frequently Asked Questions
Q: What is LOP (Loss of Pay) and how is it calculated?
LOP (Loss of Pay) refers to the days an employee is absent without approved paid leave. LOP days reduce the gross salary proportionally. The formula is: LOP Deduction = (Gross Salary ÷ Total Working Days) × LOP Days. For example, if gross salary is ₹50,000 and there are 26 working days, each day is worth ₹1,923. Two LOP days deduct ₹3,846 from the salary.
Q: What is the difference between CL, SL, PL, and LOP?
CL (Casual Leave) is for short, unplanned absences — typically 7–12 days/year. SL (Sick Leave) is for medical reasons — 7–12 days/year. PL or EL (Privilege/Earned Leave) is accrued based on days worked — typically 15–21 days/year. All CL, SL, and PL are paid leaves. LOP (Loss of Pay) occurs when an employee is absent after exhausting all approved paid leaves.
Q: How many working days does a month typically have in India?
A typical Indian work month has 24–26 working days depending on the company policy and the number of weekends. Companies with 5-day work weeks (Mon–Fri) have 20–23 working days. Companies with 6-day work weeks (Mon–Sat) have 24–26 working days. Most payroll systems use the actual working days of that month, not a fixed number.
Q: Does LOP apply if I take a half-day leave?
Yes. Most companies calculate half-day leave as 0.5 days. If you take 2 half-days without paid leave, that is 1 LOP day, and the deduction is 1/26 × Gross Salary. The exact policy varies by company — some companies treat half-days differently, so check your HR policy document.
Q: Can my employer deduct more than the LOP amount from my salary?
Under the Payment of Wages Act, 1936, deductions from wages are regulated. Employers can only make deductions that are legally permitted — LOP, PF, ESI, TDS, and other authorised deductions. Arbitrary deductions beyond LOP are illegal. If you face such deductions, you can raise a complaint with the Labour Commissioner.
Q: How does attendance percentage affect my salary appraisal?
Attendance percentage is a key parameter in performance reviews at many Indian companies. Most companies require a minimum of 75–85% attendance to be eligible for annual increments or promotions. Below 75% attendance often triggers HR escalation, warning letters, or performance improvement plans (PIP). Some companies also link attendance to variable pay and bonus eligibility.
Q: What happens if present days + paid leaves exceed total working days?
This is not logically possible in payroll — you cannot be both present and on leave for more days than the total working days. In our calculator, paid leaves are automatically capped so that Present Days + Paid Leaves never exceed Total Working Days. In practice, if an employee claims excess leaves, HR will reconcile and only approve up to the available working days.
Q: Does LOP affect PF and ESI contributions?
PF (Provident Fund) contributions are calculated on actual wages paid (i.e., net salary after LOP). If LOP reduces your Basic Salary component below ₹15,000, the employer's and employee's PF contributions reduce accordingly. ESI contributions (for employees earning up to ₹21,000/month gross) are also calculated on wages actually earned after LOP deduction.
Q: Is LOP deduction applicable for public holidays?
No. Public holidays (national and gazette holidays) are paid days and are not counted as working days. If an employee is absent the day before or after a public holiday, some companies treat that as LOP under "sandwich leave" policy. Check your company's leave policy for specific rules around public holidays.
Q: How do I calculate per-day salary for LOP in India?
The standard formula used by most Indian employers is: Per Day Salary = Gross Monthly Salary ÷ Total Working Days in that month. Note: some companies use calendar days (30 or 31) as the denominator instead of working days — this gives a slightly different per-day rate. Always clarify with your HR whether they use calendar days or working days for LOP calculation.
