Unveiling the GST Calculation Formula

Curious about the GST calculation formula and its behind-the-scenes operation? No problem! Let us walk you through the process:

  • Add GST: To calculate the GST-excluded amount, use the following formula:
    Amount × (1 + GST rate).
  • For example, if the GST rate is 8%, and the amount is 200, the calculation will be:
    200 × (1 + 8%) = 216.  
  • Subtract GST: To find out the amount excluding GST, use the formula:
    Amount ÷ (1 + GST rate).
  • For example, if the GST rate is 8% and the GST-included amount is 216, the calculation will be:
    216 ÷ (1 + 8%) = 200.
