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.
- Tax: $100 × 0.09 = $9
- Total: $100 + $9 = $109
Result: The final price with GST is $109.
