🔬 How GST Calculator India 2026: Add, Remove & Reverse GST Works

📐 Formula

Add: GST = Original × GST%/100, Final = Original + GST. Remove: Original = Final/(1+GST%/100), GST = Final − Original

GST Add/Remove (GST 2.0): CGST + SGST split 50-50 for intra-state. GST rates 2026: 0% (essentials), 5%, 12%, 18%, 28%, 40% (GST 2.0 demerit goods).

Variables:

  • Add GST: GST Amount = Original Price × GST%/100
  • Remove GST: Original = Final Price ÷ (1 + GST%/100)

📋 Step-by-Step Calculation Process

1

Adding GST

Product: ₹10,000, GST 18%. GST = ₹10,000 × 18% = ₹1,800. Final = ₹11,800 (CGST ₹900 + SGST ₹900)

2

Removing GST from ₹11,800

Original = ₹11,800 ÷ 1.18 = ₹10,000. GST = ₹11,800 − ₹10,000 = ₹1,800
