About this GST Calculator
Two directions: Add GST when you have a pre-tax price and need the invoice total, and Remove GST when you have an MRP or tax-inclusive figure and need the base value (reverse GST). For intra-state supplies in India the tax splits equally into CGST and SGST — shown separately. For inter-state supplies the full amount applies as IGST.
