GST Calculator

Our GST Calculator is designed specifically for Indian businesses and consumers to calculate Goods and Services Tax quickly and accurately. Whether you need to add GST to a price or find the base amount from a GST-inclusive price, this tool handles both scenarios.

Select your calculation type: "Add GST" to calculate tax on a base amount, or "Remove GST" to extract the original price from a GST-inclusive amount. Enter your amount in rupees, select the applicable GST rate (5%, 12%, 18%, or 28%), and click calculate.

The calculator shows the complete breakdown including CGST (Central GST) and SGST (State GST), which are equal halves of the total GST rate for intra-state transactions. For inter-state transactions, IGST applies at the full rate.

Perfect for business owners creating invoices, accountants verifying calculations, or consumers understanding tax components in their purchases. All calculations follow the standard GST formulas used across India.
