To use the Pag-IBIG contribution table calculator, you'll typically need to input your monthly salary. The calculator will then show you the corresponding contribution amount based on the updated rates set by the Pag-IBIG Fund. You can find these calculators on various financial websites or directly on the Pag-IBIG Fund's official site. Remember that your actual contributions may vary due to individual circumstances, so it's a good idea to check with Pag-IBIG or a licensed financial advisor for accurate guidance.
