Singapore Take Home Pay and CPF Calculator The pay calculator is a simple online application to compute CPF contributions and other relevant government contributions for an employee in Singapore. Notes: • | The computed CPF components include: Employer and Employee CPF contributions, Charity (CDAC, ECF, MBMF, SINDA) contributions and Skills Development Levy (SDL). | • | The salary is computed for employee with 5 days working week (Monday to Friday). This is not an issue in general, except when computing CPF contribution for an employee who have just converted to a Singapore PR. | • | CPF contribution computation for additional wage does not take into account of additional wage in the previous months. | • | The computed SDL is for a single employee. The cents should be ignored when the total SDL contribution for the company is computed. | |
