How to Calculate Salary Arrears After Minimum Wage Revision?

Salary arrears arise when a revised wage becomes effective from an earlier date, but the employee was already paid using the old wage.

Simple formula:

Revised Salary

Salary Already Paid

Monthly Arrear

Then:

Monthly Arrear × Affected Months

Total Salary Arrear

Example

Old Salary: ₹18,000

Revised Salary: ₹19,500

Monthly Difference:

₹19,500 - ₹18,000 = ₹1,500

Affected Period: 3 Months

Total Arrear:

₹1,500 × 3 = ₹4,500

The employee is therefore entitled to ₹4,500 salary arrear, subject to attendance and applicable payroll rules.

What Else Should Be Recalculated?

A salary arrear may also affect:

• PF
• ESIC
• Bonus
• Gratuity provision
• Employer cost

Do not calculate only the salary difference.

Important

Always use the effective date mentioned in the official wage notification.

Example:

Revision effective: 1 April

Revision processed: June

Then April and May payroll should also be reviewed.

Correct Payroll Process

New Wage Notification → Identify Effective Date → Find Affected Employees → Calculate Wage Difference → Recalculate PF / ESIC → Pay Arrears → Preserve Old Payroll Records

Do Not Overwrite Old Payroll

Keep the original payroll as historical evidence.

Use:

Original Payroll + Arrear Adjustment + Revision Evidence

This creates a clear audit trail.

Conclusion

Salary arrears are simply the difference between the revised payable wage and the amount already paid for the affected period.

Whenever arrears are calculated, also review PF, ESIC and other wage-linked statutory components.
