GST formulas and examples
Use these formulas to check the amount added to a tax-free price or removed from a tax-included total.
Add tax
Total = tax-free price x (1 + rate / 100)
Remove tax
Tax-free price = tax-included total / (1 + rate / 100)
Tax amount
Tax = tax-free price x rate / 100
Quick example
Starting from ₹100, a 18% rate gives ₹18 in tax and ₹118 total.
Starting from ₹118, the tax-free amount is ₹100 and the tax is ₹18.
