Add GST on top of an amount, or work out the base price and GST already included in a total — with the CGST/SGST or IGST breakup used on Indian invoices. Nothing here is sent anywhere; it's plain arithmetic that runs instantly as you type.
Add GST on top of an amount, or work out the base price and GST already included in a total — following India's CGST/SGST/IGST structure.
Adds GST on top of a base amount, or — in "remove" mode — treats your entered amount as a GST-inclusive total and backs out the base price and GST portion. The transaction type toggle then splits that GST figure the way an Indian invoice would: into equal CGST and SGST halves for a sale within the same state, or as a single IGST line for a sale between states.
