Limits, stated plainly. This does plain percentage maths only. Real GST depends on what the item is, who sells it and where - some items are exempt, some use a cess, and composition schemes differ. CGST and SGST are each half only for sales within one state; inter-state sales use IGST at the full rate. For a filing or invoice decision, check the rate for your exact goods or services on cbic.gov.in or with a tax professional.
