How to remove GST manually

Divide the gross amount by 1.18 (the "GST fraction") to get the net amount:

net = gross ÷ 1.18 → GST = gross − net

Example: ₹1,000 ÷ 1.18 = ₹847.46 net, so the GST portion is ₹152.54.

How do I take GST off a price?

Divide the GST-inclusive amount by 1.18. For example, ₹1,200 ÷ 1.18 = ₹1,016.95 net — the rest is GST.

Why is my calculated GST not just 18% of the total?

Because GST is charged on the net amount, not the gross. Taking 18% of the gross overstates the tax. Dividing by 1.18 is the correct backward calculation.
