GST Calculation Guide

What is the difference?

GST Exclusive: Use this when you have the price of an item and need to know how much to add for tax. Formula: (Price * GST%) / 100.

GST Inclusive: Use this when you have the total "MRP" or final price and need to know how much of that money is actually tax. Formula: Total - (Total / (1 + GST%/100)).

CGST vs SGST

For intrastate transactions (within the same state), the GST is split 50/50 between the Central and State governments. This tool automatically shows you that split for your records.
