Guide to Optimising Overtime Pay Management In Singapore

In Singapore, navigating the complexities of overtime pay regulations while ensuring accuracy and compliance can be a daunting task for many businesses. From calculating overtime hours to staying updated with evolving labor laws, the process demands precision and efficiency.

Understanding Overtime Pay in Singapore

In Singapore, overtime pay constitutes a critical component of labor regulations, ensuring fair compensation for employees who work beyond regular hours.

Who is eligible for overtime pay in Singapore?

According to MOM (as of February 2024), the following working overtime employees are entitled to mandatory overtime pay: 

How do you calculate overtime hours in Singapore?

Overtime pay is calculated as follows: Hourly basic rate of pay × 1.5 × number of hours worked overtime.

Please note that according to MOM, an employee can only work up to 72 overtime hours in a month. If an employer requires employees to work more than 12 hours a day (up to a maximum of 14 hours), they must apply for an overtime exemption.

You can find out more about how to calculate overtime hours in Singapore on the MOM website.

When can an employee claim for overtime?

An employee can claim for overtime if he or she works in excess of the contractual working hours.

Challenges of Manual Overtime Pay Calculations

In the digital age where technology streamlines even the most complex tasks, manually calculating overtime pay is not only outdated but also prone to errors and inefficiencies.

Here are some potential issues that you may face if you calculate overtime pay manually.

Human Error

Manual calculations are susceptible to errors, leading to inaccurate payments and potential legal disputes.  Even the most meticulous individuals can make mistakes when performing repetitive calculations, especially when fatigued or under pressure to complete tasks quickly.

A single miscalculation can result in inaccurate payments, leading to dissatisfaction among employees and potential legal disputes.


Manually calculating overtime pay is time-consuming and labor-intensive. HR personnel must meticulously review timesheets, verify hours worked, and apply the appropriate overtime rates according to labor laws and company policies. This process can be particularly cumbersome for organizations with a large workforce or employees working irregular hours across different shifts or locations.

Compliance Risks

Labor laws governing overtime pay can vary by jurisdiction and are subject to change. Staying compliant with evolving regulations requires a deep understanding of labor laws and diligent monitoring of updates. Manual calculations increase the likelihood of overlooking regulatory changes or misinterpreting complex provisions, exposing organizations to compliance risks and potential legal consequences.

Lack of Scalability

As businesses expand and employee headcounts grow, manual processes become increasingly unsustainable. Managing overtime pay for a handful of employees may be manageable using manual methods, but it quickly becomes impractical as the organization scales. Manual calculations limit scalability and hinder the HR department’s ability to efficiently manage workforce time and attendance.

Audit Trail and Reporting

Manual calculations lack transparency and audit trails, making it difficult to provide accurate records during audits or disputes.

In this digital era, manual calculations are not only outdated but also prone to errors and inefficiencies, underscoring the need for automated solutions.
