Goods and Services Tax (GST) has simplified India's tax system by replacing multiple indirect taxes. Whether you're a business owner filing GST returns, a freelancer raising invoices, or a consumer trying to understand your bill, this calculator helps you compute GST accurately. With four main rates - 5%, 12%, 18%, and 28% - applying to different goods and services, calculating GST can be confusing. This calculator works both ways: add GST to a base price (for invoicing) or extract GST from an inclusive price (to know the actual product cost). Understanding GST isn't just for compliance; it helps you price your products competitively, claim input tax credit correctly, and make informed purchasing decisions.

Select whether you want to add GST to a base amount (exclusive price) or remove GST from an inclusive price. Enter the amount and select the applicable GST rate. Most services attract 18% GST, while goods vary - essential items at 5%, standard goods at 12-18%, luxury items at 28%. The calculator breaks down the amount into CGST, SGST (for intra-state) or IGST (for inter-state transactions). For businesses, this breakdown matters for GST return filing. Experiment with different rates to see the impact on final price. If you're setting product prices, calculate backwards from your target selling price to determine the pre-GST amount you need to charge for desired margins.

The results show your base amount (pre-GST), GST amount, and final price (with GST). For intra-state transactions, GST is split equally into CGST and SGST. For inter-state transactions, it's entirely IGST. As a business, you can claim input tax credit on GST you pay on purchases, reducing your net GST liability. Keep invoices organized for this. As a consumer, the GST breakdown helps you understand how much tax you're paying on your purchases. Compare prices across products with different GST rates to make smarter buying decisions. Remember, GST is included in MRP on most packaged products, so you're already paying it even if not explicitly mentioned.
