  • Detailed Breakdown: We don't just show the total tax; we show the CGST (Central GST) and SGST/IGST split, making it easy for you to create invoices.
  • Updated Tax Slabs: Includes all official Indian GST rates: 0.25%, 3%, 5%, 18%, and 40% (Luxury/Demerit items).
  • Error-Free Accuracy: Handles complex reverse calculations (Gross to Net) with precision, eliminating manual errors.

How to Calculate GST: The Formulas

Understanding the math behind GST is important for business compliance. Our calculator uses the following official formulas:

1. Adding GST (Tax Exclusive)

If you have the base price of a product and want to add tax:

Mathematical Formulas
$$GST \ Amount = \frac{Base \ Price \times GST\%}{100}$$ $$Gross \ Amount = Base \ Price + GST \ Amount$$
2. Removing GST (Tax Inclusive / Reverse GST)

If you have the total price (MRP) and want to find the original price before tax:

Mathematical Formulas
$$Base \ Price = \frac{Total \ Price}{(1 + GST\% / 100)}$$ $$GST \ Amount = Total \ Price - Base \ Price$$

Note: For intra-state transactions, the total GST is divided equally into CGST (50%) and SGST (50%).

Understanding GST Components in India

  • CGST (Central Goods and Services Tax): This portion of the tax goes to the Central Government on an intra-state (within the same state) sale.
  • SGST (State Goods and Services Tax): This portion goes to the State Government on an intra-state sale.
  • IGST (Integrated Goods and Services Tax): This is applied when goods or services are moved from one state to another (inter-state). The Center collects this and distributes it accordingly.
