Formula to calculate GST manually

The following formulas can be used in order to calculate the GST:

  • To add GST to the base amount
    • GST Amount = Value (GST Rate ÷ 100)
    • Total value of goods or services including GST = Value + GST Amount
  • For example:

    Assuming X product has a value of 100 INR and the GST Rate on X is 18%.

    Amount of GST

    = 100 (18 ÷ 100)

    = 118 INR.

    Total value of x including GST

    = 100 + 18

    = 118 INR.

    So, according to the above calculation, the GST amount on Product X will be18 INR and net value will be 118 INR

  • To exclude GST from the base amount,
    • Amount of GST = Value – Value x [(100 ÷ (100 + GST Rate)]
    • Net Value of the goods or services = Value – Amount of GST
  • For example:

    Assuming X product has a value of 100 INR and the GST Rate on X is 18%.

    Amount of GST

    = 100 – [100(100 ÷ (100 + 18)]

    = 100 – [100(100 ÷ 118)]

    = 15.25 INR

    Net Value of X excluding GST

    = 100 – 15.25

    = 84.75 INR

    So, according to the above calculation, the GST amount on Product X will be 18 INR and net value will be 118 INR
