Frequently Asked Questions

What is the difference between GST Inclusive and GST Exclusive amounts?

GST Exclusive means the tax amount has not been added to the base price of the item yet. GST Inclusive means the tax percentage is already built into the total price, requiring a reverse calculation to find the base value and tax split.

How are SGST and CGST split in the calculator?

For intra-state transactions under Indian tax compliance, the total GST is divided equally between State GST (SGST) and Central GST (CGST). The calculator automatically handles this division and prints the precise splits.

What are the standard GST tax rate slabs globally?

Different countries apply varying VAT/GST rates. For example, India applies 5%, 12%, 18%, and 28% slabs. The calculator provides presets for these standard rates while offering a custom slider so you can calculate any tax rate globally.
