CPF contributions are calculated from the employee's wages and the wages are classified into 2 categories (following the definition from the CPF's Board):
- Ordinary wages: Wages due or granted wholly and exclusively in respect of an employee's employment in that month and payable before the due date for payment of CPF contributions for that month. This includes allowances.
- Additional wages: Wages which are not granted wholly and exclusively for the month. These are the annual bonus, leave pay, incentives and other payments made at intervals of more than a month.
