Formulas Used in a GST Calculator India

A GST calculator uses two basic formulas. The formula depends on your calculation type.

1. Formula for GST Exclusion (Adding Tax)

You use this formula when you want to add tax to the base price.

GST Amount = (Original Cost * GST Rate) / 100
Total Price = Original Cost + GST Amount

2. Formula for GST Inclusion (Removing Tax)

You use this formula when the price already includes the tax amount.

GST Amount = Total Price – (Total Price * (100 / (100 + GST Rate)))

How the Calculator Works with Examples

Our GST calculator online structure is very simple. You must enter your original amount first. Then you select the correct tax rate percentage. Finally, you select your calculation type from the options.

Example of GST Exclusion

You buy a laptop for ₹50000. The tax rate is 18%. You want to add tax to this price.

  • Original Amount: ₹50,000
  • GST Rate: 18%
  • GST Amount: (50000 * 18) / 100 = ₹9,000
  • Total Amount: 50000 + 9000 = ₹59,000

Example of GST Inclusion

You buy a smartphone for ₹11200. This price includes 12% tax. You want to know the original price.

  • Total Amount: ₹11,200
  • GST Rate: 12%
  • Taxable Value: 11200 * (100 / (100 + 12)) = ₹10,000
  • GST Amount: 11200 – 10000 = ₹1,200
