Frequently Asked Questions

What's the difference between GST exclusive and inclusive pricing?

GST Exclusive: The price entered does NOT include GST. The calculator adds the GST amount to this price to give you the final total. This is common when businesses quote prices before tax.

GST Inclusive: The price entered ALREADY includes GST. The calculator works backward to determine the original price of the goods/services and the GST amount embedded within the total. This is often used by consumers who see a final price and want to know the tax component.

How to compute reverse GST from total amount?

To compute reverse GST (i.e., find the original amount before tax from a GST-inclusive price), use the "GST Inclusive" option in our calculator. Input the total amount you paid (which includes GST) and the applicable GST rate. The calculator will then display the original amount and the exact GST amount that was part of your total.

What are India's basic GST rates?

India's Goods and Services Tax (GST) regime primarily features four main tax slabs: 5%, 12%, 18%, and 28%. Additionally, some essential goods and services are exempt (0% GST), while certain luxury items or demerit goods fall under the highest slab. There are also special rates for specific items like precious stones (0.25%) or certain textiles (3%).
