How to calculate GST in Singapore?

To calculate Singapore GST (currently 9% as of 2024), multiply the pre-tax price by 0.09. Add this tax amount to the original price to determine the final cost payable.

Formula

GST Amount = Price × 0.09 Total = Price + GST Amount

Worked Example

An item costs $100 SGD.

  1. Tax: $100 × 0.09 = $9
  2. Total: $100 + $9 = $109

Result: The final price with GST is $109.
