The Goods and Services Tax (GST) is a unified multi-stage consumption tax levied in India and many countries worldwide. Our Free Online GST Calculator helps buyers, sellers, freelancers, and business owners calculate GST Inclusive and Exclusive amounts in seconds.

GST Calculation Modes:

  • GST Exclusive: Add GST to the base net price to find total gross invoice amount.
  • GST Inclusive: Extract the base price and total tax from an MRP or gross amount.
  • Indian Tax Slabs: One-click presets for standard 0%, 5%, 12%, 18%, and 28% GST rates, plus custom percentages.

Indian GST Formula Reference:

GST Exclusive Formula: GST Amount = (Base Price × GST Rate) ÷ 100 | Gross = Base Price + GST Amount

GST Inclusive Formula: Base Price = Gross Amount ÷ (1 + (GST Rate ÷ 100)) | GST Amount = Gross Amount - Base Price

Frequently Asked Questions

What is the difference between GST Inclusive and Exclusive?

GST Inclusive means the tax is already bundled into the total price (e.g., MRP). GST Exclusive means the tax must be added on top of the base product price.

How is CGST and SGST calculated?

For intra-state sales within the same Indian state, total GST is divided equally: 50% CGST (Central Government) and 50% SGST (State Government).
