Worked out from Central Board of Indirect Taxes and Customs, GST rate structure (5%, 12%, 18%, 28%) and CGST/SGST/IGST heads and 3 other sources.
The rate is whatever you enter. Statutory GST/VAT/HST rates change by jurisdiction, supply type and budget - confirm the rate for your supply before relying on the figure.

How this is worked out

3 steps
  1. Tax = amount x rate / 100 = 100 x 18 / 100 = 18
  2. Total = amount + tax = 100 + 18 = 118
  3. Tax at 18% = 18
