The GST Calculator adds or removes Goods and Services Tax from a price and splits it into CGST and SGST (for intra-state sales) at rates of 5%, 12%, 18% or 28% as applicable — the standard slabs used across most goods and services in India under the GST regime.
For intra-state transactions, GST is split equally between CGST (Central GST) and SGST (State GST) — an 18% GST bill means 9% CGST + 9% SGST, both going to different government treasuries — while inter-state sales instead charge IGST at the full rate to a single authority; this calculator shows the intra-state split businesses need for invoicing.
CGST and SGST apply together on sales within the same state, split equally between central and state governments. IGST applies as a single tax on inter-state sales, collected by the central government and later apportioned to the destination state.
Divide the GST-inclusive price by (1 + GST rate/100). For an ₹1,180 price inclusive of 18% GST, the base price is 1180 ÷ 1.18 = ₹1,000. This calculator's 'remove GST' mode does this automatically.
