LOP Calculator (Loss of Pay)

Calculate salary deduction for absent days and find your final payable salary.







Calculate the exact salary deduction for any unpaid leave days in seconds — works for both the 30-day and working-day method used by Indian companies.

💡 Quick tip: Not sure how many working days your company uses? Most Indian companies use either 30 calendar days or the actual working days (excluding Sundays and public holidays). See the section Which method does my company use? below to figure it out in 30 seconds.

What is LOP (Loss of Pay)?

LOP stands for Loss of Pay — a salary deduction applied when an employee is absent from work on a day they are not entitled to paid leave. It is also called Leave Without Pay (LWP) in some organisations, especially in the public sector.

LOP happens in any of these situations:

  • You’ve used up all your paid leave (casual, sick, earned leave) but still need to take time off
  • You’re absent without prior approval from your manager or HR
  • You take leave during your probation period before paid leave entitlement begins
  • You take leave during your notice period when the company restricts paid leave use
  • You’re late or leave early beyond the permitted threshold (treated as half-day LOP in many companies)

LOP is legal in India under the Payment of Wages Act, 1936 — as long as the deduction doesn’t reduce your salary below the applicable minimum wage and the policy is clearly documented in your employment agreement.

How Is LOP Calculated? (The Formula)

The standard LOP calculation formula used across Indian payroll is:

LOP Deduction = (Monthly Salary ÷ Working Days in the Month) × Number of LOP Days

Final Payable Salary = Monthly Salary − LOP Deduction

The only variable that changes between companies is what counts as “working days.” There are two accepted methods.

Method 1: Calendar Days Method (30-Day Basis)

Most companies in India use 30 calendar days as the divisor regardless of how many days the month actually has. This is the simplest method.

Formula: Per Day Salary = Monthly Salary ÷ 30

Method 2: Working Days Method

Some companies — especially manufacturing, BPO, and shift-based industries — use the actual working days in the month, excluding Sundays and public holidays. This typically gives 22–26 working days per month.

Formula: Per Day Salary = Monthly Salary ÷ Actual Working Days

Comparison: Same Salary, Same LOP — Different Deduction

Detail 30-Day Method Working Days Method (22 days)
Monthly Salary ₹45,000 ₹45,000
Per Day Salary ₹1,500 ₹2,045
LOP Days 2 2
LOP Deduction ₹3,000 ₹4,090
Final Payable ₹42,000 ₹40,910

👉 Notice: The working-days method results in a higher per-day deduction. This matters most when you’re planning unpaid leave — ask your HR which method applies to you before taking LOP.

LOP Calculator Examples (Real Scenarios)

Example 1: A 30-Day Month, 2 LOP Days

  • Monthly Salary: ₹50,000
  • Working Days: 30 (calendar method)
  • LOP Days: 2

Calculation:

  • Per Day Salary = 50,000 ÷ 30 = ₹1,666.67
  • LOP Deduction = 1,666.67 × 2 = ₹3,333.34
  • Final Payable = 50,000 − 3,333.34 = ₹46,666.66

Example 2: Working Days Method, 3 LOP Days

  • Monthly Salary: ₹60,000
  • Working Days: 22 (Sundays + 2 holidays excluded)
  • LOP Days: 3

Calculation:

  • Per Day Salary = 60,000 ÷ 22 = ₹2,727.27
  • LOP Deduction = 2,727.27 × 3 = ₹8,181.81
  • Final Payable = 60,000 − 8,181.81 = ₹51,818.19

Example 3: Half-Day LOP

Many companies apply half-day LOP when employees arrive late beyond a defined threshold (commonly 30 minutes) or leave early.

  • Monthly Salary: ₹40,000
  • Working Days: 30
  • Late arrival: 1 day (counted as half-day LOP)

Calculation:

  • Per Day Salary = 40,000 ÷ 30 = ₹1,333.33
  • Half-Day LOP Deduction = 1,333.33 × 0.5 = ₹666.67
  • Final Payable = 40,000 − 666.67 = ₹39,333.33

Which Method Does My Company Use?

Most employees don’t know which method their company applies — until they see a confusing payslip. Here’s how to find out:

  • Check your offer letter or employment contract. The salary calculation method is usually mentioned in the “Compensation” or “Payroll” section.
  • Check your company’s HR policy document. This is usually available on your company intranet, HRMS portal, or by request from HR.
  • Look at a payslip with a known LOP day. Take your gross salary, divide it by 30, and check if that matches your daily deduction. If not, try dividing by 22 or 26. Whichever matches is the method used.
  • Ask HR directly. Send a short email: “Could you please confirm whether LOP deductions are calculated on a 30-day basis or on actual working days? I’d like to understand the formula before planning leave.”

How LOP Affects Your Other Salary Components

LOP doesn’t just reduce your take-home pay for the month. Because most statutory contributions are calculated as a percentage of your salary, LOP has a ripple effect on:

1. Provident Fund (PF)

PF is calculated at 12% of your Basic Salary. When LOP reduces your Basic for the month, your PF contribution that month is also lower. Over many months, this slightly reduces your long-term retirement corpus.

2. ESI (Employees’ State Insurance)

If you earn under ₹21,000 gross and are covered by ESI, your contribution (0.75% of gross) reduces proportionally when LOP cuts your gross salary.

3. Gratuity

Gratuity is calculated based on your last drawn basic salary when you leave the company. If you have LOP in your final month, it can slightly reduce your gratuity payout. This matters most if you’re planning to resign — try to avoid LOP in your final salary month.

4. Bonuses and Incentives

If your company pays attendance-linked bonuses or performance incentives, frequent LOP days can reduce these payouts.

LOP During Notice Period — What You Need to Know

This is one of the most common — and expensive — LOP situations.

When you serve your notice period after resignation, most companies restrict paid leave use. Any absence during this time may be marked as LOP, which:

  • Reduces your final salary
  • Extends your notice period (you may have to work the LOP days back)
  • Affects your Full & Final Settlement (F&F) amount

Practical tip: Before resigning, check your remaining paid leave balance. If you have unused leave, you may be able to encash it (depending on company policy) rather than losing pay during notice.

🔗 Use the Notice Period Calculator to calculate your exact last working day, or the Experience Calculator to verify your total service tenure for F&F.

How to Reverse a LOP Deduction

If LOP was applied incorrectly — for example, you had leave approved but it was wrongly marked as unpaid — you can request a LOP reversal. Here’s the standard process:

  1. Identify the error on your payslip. Note the specific date(s) marked as LOP.
  2. Gather supporting documents — leave approval email, manager’s WhatsApp approval, or medical certificate for sick leave.
  3. Send a written request to HR within the same payroll cycle if possible. Use a short, factual email rather than a verbal request.
  4. Follow up if not actioned within 7 working days. Most companies reverse the deduction in the next month’s payroll.

LOP vs LWP vs Absent — What’s the Difference?

These terms are often used interchangeably in India, but there are subtle distinctions:

Term Full Form Used When Salary Impact
LOP Loss of Pay Most Indian private sector payroll Salary deducted
LWP Leave Without Pay Public sector, government, formal unpaid leave Salary deducted
Absent — Unauthorised absence with no prior approval Salary deducted + possible disciplinary action

In most company payslips, LOP and LWP refer to the same deduction. The calculation formula is identical. The distinction mainly matters for HR records and disciplinary tracking.

Frequently Asked Questions (FAQ)

What does LOP mean in salary?

LOP stands for Loss of Pay. It’s a salary deduction applied when an employee is absent from work on a day they are not entitled to paid leave — usually because their paid leave balance is exhausted, or the absence was not approved in advance.

How is LOP calculated in India?

The standard formula is: LOP = (Monthly Salary ÷ Working Days) × LOP Days. The “working days” figure depends on whether your company uses the 30-day calendar method or the actual working-days method. Both are legal under the Payment of Wages Act, 1936, provided the method is consistently applied and documented.

Is LOP calculated on basic salary or gross salary?

Most Indian companies calculate LOP on gross salary, meaning the deduction is proportional to the full monthly salary. Some companies calculate only on basic salary, which results in a smaller deduction. Check your company’s HR policy or offer letter to confirm.

What is half-day LOP?

Half-day LOP is a deduction of 50% of your per-day salary, usually applied when you arrive late beyond a defined threshold (commonly 30+ minutes) or leave significantly early. The exact rule is defined in your company’s attendance policy.

Can I avoid LOP deduction?

Yes, in a few ways: (1) Use available paid leave balance instead of unpaid leave, (2) Use comp-off if you’ve worked on a holiday or weekend, (3) Request leave approval in advance — some companies allow advance leave with adjustment in the next cycle, (4) If LOP was applied incorrectly, request a reversal with proof of approval.

How does LOP affect PF and gratuity?

LOP reduces your basic salary for that month, which means your PF contribution (12% of basic) is also lower. For gratuity, only your last drawn basic salary matters — so LOP in your final month before resignation can reduce your gratuity payout slightly.

Can a company deduct more than my actual salary due to LOP?

No. The Payment of Wages Act, 1936 prevents any deduction that would bring your salary below the applicable minimum wage. If LOP days exceed your earned days in a month, the company can only deduct up to your earned salary — not more.

Is LOP the same as unpaid leave?

Yes, functionally they are the same. “Unpaid leave” is the everyday phrase; “LOP” is the payroll term that appears on your payslip. Both mean salary is not paid for those days.

Does LOP affect my tax?

Yes, indirectly. LOP reduces your gross salary, which reduces your annual taxable income and your TDS deduction for that month. Your Form 16 at year-end will reflect the lower total earnings.

How long do I have to dispute a wrong LOP deduction?

There’s no fixed legal time limit, but you should raise it within the same payroll cycle or the next. The earlier you flag it, the easier it is for HR to reverse without affecting subsequent months’ payroll.
