Prorated Salary in Malaysia: How to Calculate an Employee's First Salary

When a new employee joins your company in the middle of the month, one of the first payroll questions employers ask is: How much salary should I pay?

Instead of paying the full monthly salary, employers usually calculate a prorated salary, which is based on the number of days the employee actually worked during that salary period.

In this guide, we'll explain how to calculate an employee's first salary in Malaysia, the common prorated salary methods, and payroll considerations such as EPF, SOCSO, EIS and PCB.

What is a Prorated Salary?

A prorated salary is a partial salary paid to an employee who does not work the entire payroll period.

This commonly happens when an employee:

Joins the company mid-month
Resigns before the end of the month
Returns from unpaid leave
Takes extended unpaid leave

For example, if an employee starts work on 15 July, they are generally paid only for the days worked from 15 July to 31 July.

Is Salary Proration Required in Malaysia?

Yes. Employers generally pay employees based on the period they have worked.

However, the Employment Act 1955 does not prescribe a single formula for calculating prorated salary. Employers may use different calculation methods as long as they are applied consistently and comply with the employment contract or company policy.

Common Methods to Calculate Prorated Salary

There are several methods commonly used by employers in Malaysia.

1. Calendar Days Method

This method divides the monthly salary by the total number of calendar days in the month.

Formula

Monthly Salary ÷ Number of Calendar Days × Days Worked

Example

Monthly Salary: RM3,000

Employee starts: 15 July

Calendar days in July: 31

Days worked: 17

RM3,000 ÷ 31 × 17

First Salary = RM1,645.16

2. Working Days Method

Some companies calculate salary based only on working days (excluding weekends and public holidays).

Formula

Monthly Salary ÷ Total Working Days × Days Worked

Example

Monthly Salary: RM3,000

Working days in July: 23

Days worked: 13

RM3,000 ÷ 23 × 13

First Salary = RM1,695.65

3. Ordinary Rate of Pay Method

Some employers calculate salary based on the Ordinary Rate of Pay under the Employment Act for certain payroll calculations.

The exact calculation depends on the company's payroll policy and employment terms.

Which Method Should Employers Use?

There is no single mandatory method for salary proration in Malaysia.

Many employers choose one of the following:

Calendar days
Working days
Company payroll policy

Whichever method is used, it should be applied consistently to all employees.

Do EPF, SOCSO and EIS Apply to a Prorated Salary?

Yes.

If an employee joins mid-month and receives a prorated salary, statutory contributions are generally calculated based on the actual wages paid for that month, subject to the applicable contribution tables and regulations.

Employers should ensure payroll calculations are accurate before submitting monthly contributions.

What About PCB (Monthly Tax Deduction)?

PCB (MTD) is generally calculated based on the employee's taxable income for that payroll period.

If the employee's first salary is lower because it is prorated, the PCB amount may also be lower, depending on the employee's overall tax profile.

Payroll Tips for Employers

When calculating a new employee's first salary:

Confirm the employee's official joining date.
Use a consistent salary proration method.
Check your employment contract or company policy.
Calculate EPF, SOCSO, EIS and PCB based on the applicable rules.
Keep payroll records for future reference.

Using payroll software or salary calculators can also help reduce manual errors.
