Performance Bonuses: A Motivator and a Payroll Challenge
In Malaysia performance bonuses have a big impact on employee motivation and recognition of great work. They boost morale and reward good results — but they also bring up a question HR teams tackle every year:
“How can we figure out bonuses when people start or leave mid-year?”
This is where prorated bonuses come into play. To be fair, companies adjust bonuses based on how long each employee worked during the bonus period.
In this guide, you’ll learn about:
- How performance and prorated bonuses work
- Whether companies must pay them
- How to figure out prorated bonuses
- How EPF, SOCSO, and PCB apply to bonuses
- How HRMS software simplifies the process
What Is a Performance Bonus?
A performance bonus is a cash reward that recognizes an employee’s work during a review period linked to goals or company results.
Unlike fixed pay, bonuses are optional — they depend on performance, company rules, or contract terms.
Examples of performance bonuses:
- Yearly performance bonuses
- Bonuses for finishing projects
- Sales or KPI-based rewards
What Is a Prorated Bonus?
A prorated bonus gives employees a portion of the yearly bonus if they didn’t work the full year — for instance, if they started midway or quit before bonus distribution.
A prorated bonus in Malaysia is a partial performance bonus that has a calculation based on the time an employee worked during the bonus period
This ensures fairness and consistency for all employees regardless of when they started or left.

Do Malaysian Employers Have to Pay Bonuses?
No. Performance bonuses are not required under Malaysian law, unless:
- The employment contract or collective agreement says so, or
- The company’s internal policy makes this promise.
Companies decide:
- If new hires or probationers can get bonuses.
- If a minimum time of service is needed (like 6 or 12 months).
Even though the law doesn’t require them, bonuses are still a powerful way to increase retention and motivate employees — in fields with lots of competition.

How to Calculate Performance & Prorated Bonuses
In Malaysia, people often use two ways:
Method 1: Dividing by Months, Weeks, or Days
This way splits the whole bonus period by the time the employee was there.
Formula:
Prorated Bonus = (Months Worked ÷ Total Months in Bonus Period) × Full Bonus
Example:
Employee started: July 15, 2024
Bonus period: Jan 1 – Dec 31, 2024
Full-year bonus: RM5,000
Worked: ~5.5 months
Prorated Bonus:
(5.5 ÷ 12) × RM5,000 = RM2,292

Tip: You get more accurate results when you prorate by weeks or days instead of months, because months don’t all have the same number of days.
Method 2: Proration by Actual Workdays
This approach relies on total working days rather than calendar months.
Typical working days in Malaysia (2024):
- 5-day workweek → 260 days/year
- 6-day workweek → 313 days/year
Formula:
Prorated Bonus = (Days Worked ÷ Total Working Days in Bonus Period) × Full Bonus

This calculation produces the most precise figure as it takes into account weekends, holidays, and unpaid leave.
How to Handle Bonuses for Employees Who Leave
Companies often limit bonus payments to employees on the payroll when bonuses are distributed.
Still, some companies provide partial bonuses to employees who quit before bonus time, as a nice gesture. In these situations, HR applies the same prorated formula — worked out up to the employee’s final day on the job.
EPF, SOCSO & PCB Deductions on Bonuses
Performance and prorated bonuses fall under Additional Wages (AW) in Malaysian payroll rules.
This means they get taxed for:
- EPF (Employees Provident Fund)
- SOCSO (Social Security Organisation)
- EIS (Employment Insurance System)
- PCB (Potongan Cukai Bulanan / Monthly Tax Deduction)
Example – EPF Deduction on Bonus:

Note: Always check EPF’s official contribution table to get the latest rates.

When you avoid these mistakes, you keep your employees’ trust and follow the rules.
