Instantly calculate CGST, SGST, and IGST for your business invoices.
Running a business in India means navigating the complexities of the Goods and Services Tax (GST) system on a daily basis. Whether you are a freelancer generating your first invoice, a retail shop owner billing customers, or a corporate accountant filing monthly GSTR returns, manual tax calculations are prone to human error. The Hargod GST Calculator is a premium, lightning-fast, and 100% free online utility designed to automate this entire mathematical process instantly.
One of the most common confusions for business owners is understanding when to add GST and when to extract it. Our tool provides a seamless toggle for both scenarios:
Use this mode when you know the base price of your product or service and need to calculate how much tax to add on top of it to generate the final invoice.
Formula: GST Amount = (Original Cost × GST %) / 100
Use this mode when you have a final MRP (Maximum Retail Price) that already includes the tax, and you need to reverse-calculate to find out what the actual base value of the product is, and exactly how much tax was collected.
Formula: GST Amount = Original Cost - [Original Cost × {100 / (100 + GST %)}]
India's dual GST model depends entirely on the "Place of Supply." Our tool allows you to switch between these modes to perfectly format your invoices:
