How GST is Calculated

GST can be calculated in two ways:

1. Adding GST

Used when product price is exclusive of tax.

Formula:

GST Amount = Base Amount × GST Rate ÷ 100

Final Amount = Base Amount + GST

2. Removing GST

Used when product price already includes GST.

Formula:

GST Amount = Inclusive Price − (Inclusive Price ÷ (1 + GST Rate ÷ 100))

Example of GST Calculation

Suppose:

  • Product Price = ₹10,000
  • GST Rate = 18%

GST Amount:

₹1,800

Final Amount:

₹11,800

What is a GST Slab?

A GST slab refers to a predefined tax percentage applied to products and services.

Common GST slabs include:

  • 3%
  • 5%
  • 12%

Different products may fall under different slabs.

Examples include:
