Here’s what makes this GST Calculator Online different: when you calculate, the tool doesn’t just show a single tax number. It automatically splits the total GST into CGST (Central GST) and SGST (State GST) – each displayed right below the breakdown. For instance, if your GST is ₹360, you’ll see CGST: ₹180 and SGST: ₹180. This reflects how Indian tax invoices are designed. No need for manual partitioning.
Switch to “Remove GST” mode, enter the inclusive total, select the GST rate, and the tool shows your base amount before tax.
