How to Calculate GST

Adding GST (Exclusive)

When you have the base price and want to find total

GST = Base × Rate ÷ 100
Total = Base + GST

Example: ₹1,000 + 18% = ₹1,180

Removing GST (Inclusive)

When you have the total and want to extract GST

GST = Total × Rate ÷ (100 + Rate)
Base = Total − GST

Example: ₹1,180 total → GST = ₹180
