How It Works: GST on Discount Calculator

Under Section 15 of the Central Goods and Services Tax (CGST) Act, any discount given before or at the time of supply and duly recorded on the invoice is deducted from the transaction value before calculating GST. Therefore, GST is charged strictly on the net discounted price, not on the original MRP.

Formula & Calculation Methodology

Discount Amount = (Original Price × Discount Rate) / 100
Taxable Discounted Price = Original Price - Discount Amount
GST Amount = (Taxable Discounted Price × GST Rate) / 100
Final Amount Payable = Taxable Discounted Price + GST Amount

Notice: Designed to provide accurate results based on the standard formulas described above.
