About this tool

Indian GST applies slab rates such as 0%, 5%, 12%, 18%, and 28%. This GST calculator adds tax to a net amount or extracts tax from a gross amount for the slab you select.

Exclusive mode starts from the price before GST; inclusive mode backs tax out of a shelf price. Exempt and niche cases still need the rate your invoice actually uses — the control is yours.

For VAT-style European or Japanese consumption tax see the VAT page. For any country’s headline rate, use the world tax calculator or type a custom percent.

Formula

  • Exclusive: tax = net × rate
  • Inclusive: net = gross ÷ (1 + rate)

How it is calculated

  1. Choose the GST slab (or 0% exempt).
  2. Enter amount as exclusive or inclusive of tax.
  3. Read net, tax, and gross.
  4. If your country, school or provider uses different rules, pick another option in the “Standard” menu at the top.

Questions

CGST + SGST vs IGST?

Intra-state invoices split the slab (9%+9% for 18%). Inter-state uses IGST at the same total. This calculator shows the combined tax.

When should I change the “Standard” setting?

When the rules you work with differ from the default chosen for your language. Options on this page: India GST 5%; India GST 12%; India GST 18%; India GST 28%; India GST 0% / exempt. The formula, steps and result update to match your choice.
