Understanding the GST Calculator

The Goods and Services Tax (GST) is a unified, multi-stage, destination-based tax that is levied on every value addition in the supply chain. In India, GST has replaced many indirect taxes such as excise duty, VAT, and service tax. Our GST calculator is a handy tool for businesses and consumers to calculate the amount of GST payable on a product or service, or to determine the base price of an item when GST is already included in the final price.

Why Use Our GST Tool?

Calculating GST involves determining the applicable tax slab (5%, 12%, 18%, or 28%) and then applying the formula correctly based on whether the tax is being added or inclusive. For businesses, this is vital for accurate invoicing and tax filing. For consumers, it brings clarity to the actual cost of products and services they consume.

How to Use the GST Calculator

To find the GST amount, follow these simple steps:

  1. Enter the net price or the total price of the service/goods.
  2. Select the relevant GST percentage from the standard slabs (5%, 12%, 18%, 28%).
  3. Select 'Add GST' if you want to find the final price including tax, or 'Remove GST' if you have the total price and want to find the original base price.

The calculator instantly shows the CGST, SGST (or IGST), and the total product cost.

Real-World Examples

Example 1 (Inclusive): You bought a smartphone for ₹20,000, and the GST rate is 18%. By selecting 'Remove GST', the tool shows that the base price was ₹16,949 and the GST paid was ₹3,051.

Example 2 (Exclusive): You are selling a consulting service for ₹10,000 + 18% GST. The tool calculates the tax as ₹1,800, making the total invoice amount ₹11,800.
