Turn a pre-GST managed security, VAPT or vCISO quote into the amount you actually pay, including 18% GST and card or forex charges.
Enter the quoted price before GST, the GST rate (18% for most IT and security services; confirm your supply on the CBIC site) and any card, forex or bank charges. The tool shows the GST amount and the total cash you pay.
Worked example (illustrative). A VAPT quote of ₹3,00,000 + 18% GST = ₹54,000, total ₹3,54,000. If the provider is in another state, the ₹54,000 is IGST; within your state it is split ₹27,000 CGST + ₹27,000 SGST.
Foreign platforms. If you are GST-registered and buy from a supplier outside India, there is usually no GST on the invoice; you pay 18% IGST yourself under reverse charge and normally claim it back as input tax credit. Enter the rupee value, keep 18%, and add the card's forex markup in the charges field to see the cash outflow before the credit comes back.
Limits. The credit is only available if you are registered, the service is used for taxable business supplies and the conditions of the CGST Act are met. TDS may also apply. See GST, TDS and dollar pricing and confirm with your CA.
