PRICE ALREADY INCLUDES TAX

GST Inclusive Calculator

Find the taxable value inside a GST-inclusive price. This is useful when a retail price or vendor quote already includes GST.

Formula for removing GST

Divide the inclusive amount by 1 plus the GST rate as a decimal. For example, ₹1,180 ÷ 1.18 = ₹1,000 before tax, leaving ₹180 as GST. Do not subtract 18% directly from ₹1,180 because that produces an incorrect base.
