Calculate GST inclusive/exclusive with CGST, SGST, IGST split — instantly.
Enter the base amount, select the GST slab (5/12/18/28%), and the calculator shows the GST amount plus total. For intra-state supply, it splits into CGST + SGST (half each). For inter-state, it shows IGST as the full GST amount.
CGST + SGST applies when seller and buyer are in the same state (half each). IGST applies when they're in different states — the full GST goes as IGST to the central government, which later distributes to the destination state.
If ₹118 is the final GST-inclusive amount at 18%, the base is ₹118 ÷ 1.18 = ₹100 and GST is ₹18. Switch the calculator to 'Inclusive' mode to do this automatically.
Most services are at 18%. Essential food items are typically 5%. Luxury goods are at 28%. Refer to the official GST rate schedule or ask your CA — this tool doesn't determine the rate, only calculates it.
