Half the GST confusion in small F&B outlets comes from not being sure whether a number already includes tax. This calculator handles both directions: give it a base amount and it adds GST, or give it a final billed amount and it extracts the tax, with the CGST/SGST split shown either way.
To add GST: GST amount = amount times rate divided by 100. To extract GST from a tax-inclusive figure: base = amount divided by (1 plus rate divided by 100).
| Amount | 1000 ₹ |
| GST rate | 5 % |

For intra-state supply, GST is split into Central GST and State GST at half the total rate each, so a 5% GST bill shows as 2.5% CGST and 2.5% SGST. Inter-state supply instead charges IGST at the full combined rate, this calculator assumes the intra-state case.
