How to use the Free Indian GST Calculator?

Our Advanced GST Calculator is designed to help business owners, freelancers, and consumers quickly figure out the exact tax amount. Whether you are generating a bill or trying to understand the original price of a product, this tool does the complex math for you instantly.

Add GST (Exclusive Calculation)

If you have a base price of a product and want to know how much to charge your customer after applying GST, use the "Add GST (+)" option. For example, if your service costs ₹10,000 and falls under the 18% slab, the calculator will instantly show that you need to add ₹1,800 as tax (₹900 CGST + ₹900 SGST), making the final bill ₹11,800.

Remove GST (Reverse / Inclusive Calculation)

If you purchased a product for ₹11,800 which already includes 18% GST, and you want to know the original price (base price) to claim Input Tax Credit (ITC), use the "Remove GST (-)" option. The tool will calculate backwards and reveal that the actual base price was ₹10,000.
