Calculate GST for inclusive or exclusive pricing
Use this GST calculator to estimate tax amount, taxable value, invoice total, and whether the tax splits into CGST plus SGST or IGST. It is useful for quick invoice planning before you file or register.
Enter the amount on which GST should be calculated.
Invoice breakdown
This is a quick estimate for planning and invoice checks. Final GST treatment still depends on the actual nature of goods, services, place of supply, exemptions, and invoice context.
Estimate how much GST to add to a quote or how much tax is already included in a final price.
See whether the tax likely splits as CGST plus SGST or applies as IGST for the transaction.
Use the result as a quick estimate, then move into GST registration or filing support if you need operational help.
