GST Calculator - Free Online Calculator
GST calculation is simple once you know whether the price is inclusive or exclusive of tax. This calculator helps you convert between the two and shows the CGST/SGST or IGST split for quick invoice planning.
Use the correct GST rate for your category of goods or services. If you are unsure, verify from the official GST portal or your tax consultant. A small rate mismatch can lead to incorrect invoice totals.
For businesses, it is useful to test multiple prices to see how GST affects final customer price or margin. Combine this with the profit margin calculator to set the right base price.
If you issue invoices across states, use IGST rates and verify place of supply rules. The calculator helps estimate values, but compliance needs official verification.
