GST Calculator
Calculate GST, CGST, SGST and total invoice value.
What is GST?
Goods and Services Tax (GST) is an indirect tax used in India. This calculator helps estimate GST on a taxable amount and can show the total amount after tax. Depending on the transaction, GST may be represented through components such as CGST and SGST or IGST.
For an intra-state example with an 18% total GST rate, the rate is commonly split into 9% CGST and 9% SGST. The correct treatment depends on the nature and place of supply, so businesses should verify the applicable rules.
GST inclusive vs exclusive amounts
A GST-exclusive amount is the taxable base before GST. A GST-inclusive amount already contains GST. When issuing invoices or checking prices, confirm which type of amount you are working with before calculating.
