Understanding GST in India.
The standard Goods and Services Tax (GST) rate for most goods in India is 18%. This calculator isolates the net value and GST amount from any gross purchase total using standard international calculation guidelines.
How to Back Out VAT/GST in India
To calculate the pre-tax net cost (base amount) from a gross total that includes a standard 18% GST, apply the reverse VAT calculation formula:
Net Price = Gross Amount / (1 + (18 / 100))
Which simplifies to dividing the total by 1.18.
For example: If you paid a total of ₹120.00 inclusive of 18% VAT:
- Divide the gross amount:
₹120.00 / 1.18 = ₹101.69(Net Price). - Subtract the net amount from total paid to extract the tax portion:
₹120.00 - ₹101.69 = ₹18.31(Extracted tax).
