Calculate GST on a taxable value or extract GST from a tax-inclusive total. Split CGST, SGST and IGST in one compact workspace.
The calculator will add GST to the amount entered below.
A forward GST calculation starts with the taxable value and adds the applicable GST. A reverse GST calculation starts with the GST-inclusive total and extracts both the original taxable value and the included tax. This is useful for invoices, quotations, retail pricing, reconciliation and checking tax-inclusive vendor bills.
Enter the taxable amount, choose the rate and calculate the final invoice value.
Enter a GST-inclusive amount and recover the taxable value and included GST.
For eligible intrastate supplies, the GST amount is shown as equal central and state portions.
Switch the supply type to show the applicable GST amount as IGST.
Multiply the taxable value by the GST rate and divide by 100. Add the GST amount to the taxable value to obtain the GST-inclusive invoice total.
Divide the GST-inclusive total by one plus the GST rate expressed as a decimal. The result is the taxable value. Subtract that amount from the total to identify the included GST.
IGST is generally associated with interstate supplies. Place-of-supply rules can be more complex than the physical location of the parties, so the correct tax treatment should be verified.
