The GST Calculator adds or removes Goods and Services Tax at any rate and splits the GST into equal CGST and SGST components for intra-state transactions. Preset buttons cover the standard slabs of 3%, 5%, 12%, 18% and 28%.
Calculate GST both ways
Add GST to a base price to find the invoice total, or remove GST from a tax-inclusive amount to find the taxable value. For intra-state supply, GST is divided equally between Central GST (CGST) and State GST (SGST), and the calculator shows both halves automatically.
Outputs
- Net (taxable) amount
- Total GST and the CGST / SGST split
- Final amount including GST
