3. Legal Compliance

Types of GST Calculation Solutions
1. Manual GST Calculation Support
Ideal for small businesses and freelancers who need formula-based assistance.
Formula when GST is exclusive:
GST Amount = (Purchase Value × GST Rate) ÷ 100
Total Price = Purchase Value + GST
Example:
If goods cost ₹10,000 and GST rate is 18%:
GST = (10,000 × 18) ÷ 100 = ₹1,800
Total = ₹11,800
2. GST Extraction from Inclusive Price
When GST is already included in the price:
GST Amount = (Inclusive Price × GST Rate) ÷ (100 + GST Rate)
Example:
Inclusive price = ₹11,800
GST Rate = 18%
GST = (11,800 × 18) ÷ 118 = ₹1,800
Original Price = ₹10,000
