Formula & Mathematical Methodology: Exclusive & Reverse (Inclusive) GST Formulas

Exclusive:   GST = Net × r100,   Inclusive:   Net = Gross1 + r100
Exclusive: GST = Net × (r/100), Gross = Net + GST; Inclusive: Net = Gross / (1 + r/100), GST = Gross − Net
  • Net: Taxable value before GST
  • Gross: Total invoice value including GST
  • r: Applicable GST slab percentage

Rounding: Rounded to 2 decimal places (paise).

Worked Example: ₹50,000 IT Consulting Invoice at 18% GST (Intra-State Exclusive)

An agency bills ₹50,000 net within the same state at 18% GST.

  1. Total GST = ₹50,000 × 0.18 = ₹9,000.
  2. CGST (9%) = ₹4,500; SGST (9%) = ₹4,500.
  3. Gross Invoice Total = ₹50,000 + ₹9,000 = ₹59,000.
Result: Total GST is ₹9,000 (₹4,500 CGST + ₹4,500 SGST) for a gross bill of ₹59,000.

Frequently Asked Questions

How do I remove 18% GST from a GST-inclusive price?

Never subtract 18% directly from the gross price. Instead, divide the gross amount by 1.18 to find the pre-tax net value, then subtract that net value from the gross amount.
